Effect of Snowmelt on Groundwater Bacterial Community Composition and Potential Role of Surface Environments as Microbial Seed Bank in Two Distinct Aquifers from the Region of Quebec, Canada.

Events of groundwater recharge are associated with changes in the composition of aquifer microbial communities but also abiotic conditions. Modification in the structure of the community can be the result of different environmental condition favoring or hindering certain taxa, or due to the introduction of surface-derived taxa. Yet, in both cases, the local hydrogeochemical settings of the aquifer is likely to affect the amount of variation observed. Therefore, in our study, we used 16S rRNA gene sequencing to assess how microbial communities change in response to snowmelt and the potential connectivity between subsurface and surface microbiomes in two distinct aquifers located in the region of Vaudreuil-Soulanges (Québec, Canada). At both sites, we observed an increase in groundwater level and decrease in temperature following the onset of snow melt in March 2019. Bacterial community composition of each aquifer was significantly different (p < 0.05) between samples collected prior and after groundwater recharge. Furthermore, microbial source tracking results suggested a low contribution of surface environments to the groundwater microbiome except for in the months associated with recharge (March 2019 and April 2019). Overall, despite differences in soil permeability between both sites, the period of snow melt was followed by important changes in the composition of microbial communities from aquifers.

Seed conservation of Begonia spp. from West Sumatra, Indonesia

Begonia collections in Indonesian Botanic Gardens are a source of germplasm for ornamental plants, foods, and future medicinal plants. Seed exploration activity was focused on the West Sumatra area to increase the representation of Begonia collections at the Indonesian Botanic Gardens’s Seed Bank. It will accommodate collection numbers and genetic variation. The purpose of this study was to collect seeds and living collections of the Sumatran Begonia species, mainly from West Sumatra. Beside that, this study aimed to identify the storage characteristics of Begonia seeds in the Seed Bank. The research method was carried out exploratory and investigated in several districts of West Sumatra. From the explorations, we collected 27 species of Begonias from five districts, namely Solok, Sijunjung, Tanah Datar, Lima Puluh Kota, and West Pasaman. The most Begonia species were found in Solok Regency (25%). We found those Begonias in the vegetative and generative phases. About 76.67% of the plants found produce flowers. Some plants were producing fruit (60%). Begonia habitat is generally a humid area (karst cliffs, caves, streams, forest floors and wet rocks). Furthermore, the characteristics of 30 Begonias, types of seeds, and its storage, also associated plants around Begonia will be described in this paper.

High Quality Rna Isolation and Exogenous Reference Gene for Real-time Pcr In Cedrela Odorata Seed Physiology Studies

Seed banks represent an important strategy for the conservation of forest genetic resources, although a basic understanding of the physiological changes that seeds undergo during storage that affect quality and germination is still lacking for most tropical and subtropical species. Here, we describe the optimisation of an RNA isolation procedure and reference gene normalisation for expression analysis in Cedrela odorata (cedro or Spanish cedar) seeds during different physiological states, as well as in the steady-state stem and leaf. The expression profiles of five endogenous candidate reference genes ( 18S , EF1α , GAPDH , CDC27B , PP2A2 ) and an exogenous ( HMBS ) gene were evaluated by using dedicated algorithms, including Genorm, Normfinder, Bestkeeper and Ct. We found that the expression of all endogenous genes varied considerably in response to both ageing and hydration. Therefore, using the external HMBS was a suitable alternative to evaluate gene expression in these highly contrasting physiological conditions. The reference genes EF1α and GAPDH were the most stable, and could be used for normalisation of qRT-PCR results under specific circumstances.

Effects of Rotation with Trap Crops on Striga (Striga hermonthica Del. Benth) Incidence, its Seed Bank and Sorghum Growth and Yield

A trial was conducted for three consecutive seasons (2006/07,2007/08 and 2008/09) in a field artificially infested by Striga hermonthicain the Experimental Farm of the Faculty of Agriculture, University ofSinnar. The effects of a two seasons’ crop rotation on striga incidence, itsseed bank and growth and yield of subsequent sorghum crop wereinvestigated. The rotation comprised the trap crops, cowpea (Vignaunguiculata), millet (Pennisetum glaucum), sesame (Sesamum indicum),sunflower (Helianthus annuus) and fallows, in assorted combinations. Asorghum monoculture, for the three seasons, was included as a control.All treatments reduced striga emergence significantly in comparison tosorghum monoculture. Sunflower and sesame grown for two consecutiveseasons caused the maximum reductions (80%), while a fallow followedby sorghum resulted in the least reduction (42%). Significant reduction instriga capsules (37%) was caused by two consecutive sesame crops. In thesecond season, all treatments significantly reduced striga seed bank,. Twoconsecutive fallows and two consecutive crops each of cowpea, millet andsunflower resulted in the highest reductions in striga incidence (80% -92%), while a fallow followed by sorghum exhibited the least reduction(51-65%). None of the treatments had adverse effects on sorghum standearly in the season; however, at harvest significant reduction wasobserved. Sorghum monoculture resulted in the lowest stand, whilesunflower planted subsequent to a fallow and two successive sunflowercrops affected the highest stands. Among all treatments, sorghum

Effect of Quarry Activities on Some Morphological Parameters of Two Maize Varieties (SWAN 1 and SAMMAZ 52)

The effect of quarry activities on some morphological parameters of two maize varieties (swan 1 and sammaz 52) was investigated with the aim of determining the impact of quarry activities on some growth parameters of the maize varieties under study. The seeds were collected from the Seed Bank Department of the Ondo State Ministry of Agriculture, Akure, Ondo State. They were authenticated at the Herbarium unit of the Federal University of Technology, Akure, and the voucher was deposited. Soil samples were collected at 50m, 100m, 150m, 200m, and 250m from the quarry site and transferred to the laboratory for analysis. A screen house experiment was set up to house the pots. Seeds of SWAN 1 and SAMMAZ 52 were sown into perforated plastic pots (30 cm diameter and 33 cm depth) filled with 10 kg of quarry soil. The following morphological parameters were determined; shoot height, leaf area, plant dry weight, shoot dry weight, root dry weight, root-shoot ratio, leaf area, and determination of photosynthetic parameters especially chlorophylls a and b. The result revealed that at 50 meters from the quarry site, SAMMAZ 52, one of the maize varieties grown in soil taken from the site, had the highest shoot height (94 cm). which showed that plants growing in higher concentrations of dust pollution respond to nutrient stress by devoting more of their available carbon to shoot growth, resulting in elongated stems, were consistent with the observed higher shoot height in SAMMAZ 52, daily variations in photosynthetic activity and the rate of nitrogen uptake are to blame for these alterations in plant behavior. The efficiency with which plants use the available nutrients determines whether they will survive in an area where there is quarry dust. The observed higher biomass (3.84g) under SAMMAZ 52's management regime can be attributed to the best possible rates of photosynthesis and nutrient assimilation, as well as to the presence of more chlorophyll and larger leaf surfaces.

Long-term seed bank persistence in a stochastic desert environment.

Seed banks, the collection of viable seeds in the soil, are particularly important determinants of population survival in highly variable environments. Predictions of increased stochasticity in the amount and timing of precipitation in desert environments raise the question of how seed banks of desert species will respond to climate change, and ultimately, whether these species will persist. Here, we present data from our long-term studies of germination requirements and seed bank dynamics in a rare desert gypsophile perennial, Arctomecon californica (Las Vegas bearpoppy). Arctomecon californica is a relatively short-lived plant that recruits from seed in sequences of unusually favorable years. We used germination experiments, an in situ seed bank study, and a 15-year field seed retrieval study to examine factors affecting seed bank persistence. In the germination study, a majority of seeds remained dormant, despite a wide variety of treatments, suggesting that a large proportion of the seed dispersed each year has cue-nonresponsive dormancy. Our in situ seed bank study showed that seed density varied widely between sites, among transects, and among samples within a transect. The patchiness of seeds in the soil highlights the importance of protecting large areas where A. californica populations are known to have existed in the past. The seed retrieval study provided strong evidence that this species has a long-lived seed bank in which only a small fraction of seeds (roughly 5%) become nondormant each year, allowing seed banks of this species to last up to 20 years without a seed production event. Whether this impressive life-history strategy can maintain the species in the face of climate change depends on the future frequency of the well-timed precipitation that allows for the establishment of new cohorts of adult plants.

Evaluation of Germination under Different Storage Conditions of Four Endemic Plant Species from Ethiopia: Implications for Ex Situ Conservation in Seed Banks

The conservation of endemic plant species is a major concern, as the species are with restricted distribution range. Since in situ conservation alone will not guarantee their maintenance, ex situ conservation measures must be undertaken to support the conservation of these species. Investigation of the impact of the storage environment of seeds gives baseline information. Therefore, this study was conducted to investigate the effect of different storage conditions (room temperature, 4 °C and −10 °C) and different storage periods over one year. Four Ethiopian endemic plant species, namely Euryops pinifolius, Kniphofia foliosa, Lobelia rhynchopetalum, and Solanecio gigas, were considered. Multivariate analyses revealed a significant (p &lt; 0.05) effect of storage condition and period on seed germination. The storage of seeds at room temperature before drying may not be recommended for short-term storage of the studied species, except K. foliosa. After drying of seeds, E. pinifolius, K. foliosa, and L. rhynchopetalum seeds showed high germination percentage (above 80%) after storage even at sub-zero temperatures for one year. The germination percentage of S. gigas stored at room temperature before drying for thirteen months was 60% and that stored at 4 °C was 6%, which indicates that the seeds may be categorized under intermediate storage behavior. The three species can be grouped in the orthodox seed storage category. Research on desiccation screening should be undertaken to predict an optimal combination of storage moisture content and suitable storage temperature to determine storage category with certainty.

Weed Seed Bank Density in Seven-Year-Old Conservation in No-Till System

Weed management remains a challenge when introducing new cropping systems. In Lebanon, farmers are increasingly adopting conservation agriculture (No-till) because it saves energy and reduces water and nutrient erosion. However, introducing a new system will cause a significant shift in production and management practices and is expected to produce novel weed management challenges. Thus, knowledge of soil seed banks of weeds in such systems is vital in designing effective weed management strategies. The objective of this research was to assess the size of the weed seed bank in seven-year-old conservation no-till fields. Soil samples were collected from established till and no-till fields at a depth of 0-5 cm. Transient and persistent weed seeds banks were evaluated. Results provide tangible evidence that the weed seed bank at a depth between 0-5cm in no-till system is greater than in till system. The no-till fields contained almost seven times the density of monocot and dicot weed seeds than in the conventional tilled fields. Ongoing work that builds on present results will help gain knowledge pertaining to weed seed bank dynamics in no-till system compared with conventionally tilled system.

Evaluation of two biostimulants in soybean production

The results of a study of soybean (Glycine max, (L.)) are presented, which was developed in areas of the Basic Sugarcane Seed Bank of the province of Cienfuegos, located in areas of the Espartaco community with the variety INIFAT- 70. The study was planted on May 24 and harvested on September 12 with 111 days, the application of biostimulants was carried out on July 19 at 55 days after planting, the randomized block design was used with 3 treatments (Control, FitomasEC and Fitomasplus) and 5 replicates, in plots of 36 m2. The seed used was basic from the bank itself with more than 95% germination and the study area was not fertilized. The treatments used were: Witness and/or control, FitomasEC an application at 2 liters ha-1, Fitomasplus an application 2.0052 liters ha-1 (tank mix 2 liters ha-1 of FitomasEC and 5.2 milliliters ha-1 of enerplant), The variables evaluated were ton ha-1 and the economic valuation. A simple classification analysis of variance (ANOVA) was performed and as there were significant differences between the treatments, the mean comparison test was performed using the multiple range test with Tukey's p&lt;0.05 test. For data analysis, the statistical package Statgraphics Plus 5.0 was used. It was obtained as a result that the application of biostimulants increased soybean production, resulting significant with Fitomasplus, which achieved increases compared to the control of 25% and compared to FitomasEC of 22%, the Benefit/Cost ratio reported a positive effect of 1.02 for the FitomasEC and 1.25 for Fitomasplus with respect to the control.

An Invasive Ecological Study on the Flora of Soil Seed Bank and Standing Vegetation Across Diverse Anthropo-ecosystems in Indian Dry Tropics

Plant invasions in tropical ecosystems are being increasingly realized particularly in highly dynamic but fragile dry tropical ecosystems, where there is generally little ecological information on invasions in subterranean vegetation. The present study was carried out to understand the floristic composition of both seed bank and standing vegetation across a range of five diverse anthropo-ecosystems in an urban region in Indian dry tropics. A total of one hundred soil samples (each of size of 25cm×25cm from 0-5 cm and 5-10 cm depth) from five anthropic sites (vegetation of University campus, polluted Kali River bank, Brick kiln, Waste land and Road side) were analyzed for their taxonomic position, life form and bio-geographic origin of the seedling emergents in relation to the flora in standing vegetation. A total of 221 plant species (58% aliens, 34% of aliens of American origin, 75% weedy herbs) in standing vegetation spread over 54 families were recorded in standing vegetation of the study sites with more than 55% representation from eight dominant families led by Fabaceae, Poaceae and Asteraceae followed by Malvaceae, Amaranthaceae and Solanaceae. In contrast, a total of 81 seed bank flora (10 unidentified, 62% aliens, 43% of American origin, 87% herbs) distributed over 32 angiospermic families were recorded. While none of the seed bank vegetation at any site showed significant similarity with its standing vegetation indicating the minor role of seed bank flora in the regeneration of the standing plant communities above ground. However, a considerable similarity among seed banks and standing vegetation at other sites indicated a significant possible role of anthropogenic activities in the urban regions of Indian dry tropics, evinced by the largest proportion of grasses and herbs dominated by exotics, especially of American origin. These aliens through successful naturalization via seed banks may cause homogenization of floristic structure. In conclusion, the present study revealed a heavy scale of intrusion by the alien plants dominated by American elements into not only standing vegetation but also in seed banks across the anthropic sites in urban regions in Indian dry tropics which is likely to alter the standing vegetation floristic structure with a larger abundance of alien flora.

Seed Viability, Spikelet Dispersal, Seed Banks and Seed Storage Requirements for Native and Invasive Cordgrasses (Genus Spartina) in Southwest Iberian Peninsula

Seed banks play an important role in determining the spatial and temporal distribution of halophytes in salt marshes. We tested the ability of native Spartina maritima and invasive S. densiflora spikelets to disperse by flotation on water with different salinity concentrations, and the longevity of spikelet viability relative to environmental conditions including dry or wet storage at low or moderate temperatures, and aqueous salinity concentrations from fresh to sea water. We quantified pre-dispersal seed production and pre- and post-dispersal focal Spartina spp. presence in seed banks along intertidal gradients within salt marshes at the Gulf of Cádiz (Southwest Iberian Peninsula). Spartina densiflora spikelets, especially from middle and high elevation marshes, showed greater ability than S. maritima to remain afloat, which suggests this species could be dispersed over longer distances. Wet-stored Spartina seeds were able to maintain viability for months, while seeds under dry storage rapidly lost viability. This decline was most significant for S. maritima, and for seeds stored at moderate temperatures. Storage of spikelets under wet and cold conditions optimized spikelet viability. Native S. maritima did not establish transient or persistent seed banks, while invasive S. densiflora established transient seed banks mainly at higher marsh elevations. Our results on the dynamics of seed dispersal and seed banks and seedling recruitment provide fundamental knowledge that can be applied for conservation of native S. maritima, management of invasive S. densiflora, and ecological restoration of tidal salt marshes.

Seed dormancy and storage behaviour of the Hawaiian endemic Coprosma kauensis (Rubiaceae)

Context Seed banking is the most efficient and cost-effective method of preserving plant germplasm, but not all species can be conserved by conventional practices. Further, restoration of plant populations from seeds often is hindered by a lack of a priori knowledge of seed dormancy and germination requirements. Aims Our objective was to determine seed desiccation, initial freezing tolerance and the dormancy-breaking and germination requirements of Coprosma kauensis, a dioecious shrub endemic to Kauaʻi Island in Hawaiʻi. Methods The effects of temperature and gibberellic acid (GA3) on germination of fresh seeds were tested in light/dark at 15/5, 25/15 and 20/10°C with and without treatment with GA3. To test effects of desiccation and initial freezing on germination, seeds were dried to 15% relative humidity at 15°C and then stored at −20°C. Key results Regardless of incubation temperature and treatment (or not) with GA3, final germination ranged from 78 to 88%; however, time to 50% germination decreased at 20/10°C for seeds treated with 500 ppm GA3. There was no significant difference in final germination percentage between freshly harvested seeds and those desiccated, nor of those desiccated and then subsequently frozen at −20°C. Conclusions Fresh seeds of C. kauensis exhibit a low degree of nondeep physiological dormancy. They can germinate over a range of temperatures, but germination speed is increased by GA3. Fresh seeds are desiccation and freeze tolerant (after 6 months storage). Implications This vulnerable Kauaʻi endemic species easily can be propagated from seeds. Future studies should investigate long-term longevity at various storage temperatures.

Wild Seed Conservation in National Botanical Garden, Lalitpur, Nepal

Seed banks are the important means for the ex-situ conservation of plant genetic diversity. Though the seeds of domesticated varieties have been preserved for a long time, wild seed conservation is a noble concept in Nepal. Seed Bank of National Botanical Garden, Godawari, Lalitpur (NBG) is a major initiative for the conservation of wild plant seeds in Nepal. In the present study, a standardized seed banking procedures practiced at the Seed Bank of NBG, from seed collection to storage including germination test has been included. Currently, seeds of 84 wild species belonging to 77 genera of 47 families are preserved in the NBG. Alongside preserving wild genetic resources, NBG Seed Bank also provides materials for restoration, reintroduction and research that supports broader plant conservation goals, as well as contributes to education and public awareness about plant conservation.

The Impact of N.I. Vavilov on the Conservation and Use of Plant Genetic Resources in Scandinavia: A Review

In this review we examine Nikolai Ivanovich Vavilov's relationship to Scandinavia and the impact he and his ideas have had on Scandinavia. We trace the historical connections from Vavilov back to 18th century scientists, such as Carl Von Linneaus (Sweden) and 19th century European scientists such as Alphonse de Candolle (Switzerland), Henry de Vilmorin (France), and William Bateson (England). Vavilov has influenced the conservation work in Scandinavia resulting amongst other in the establishment of the Nordic Gene Bank in 1979 and the Svalbard Global Seed Vault which started operating in 2008. Vavilov travelled to Scandinavia in 1921 and in 1931 to give lectures and exchange ideas, especially with the breeders at the Swedish Seed Association (Svalöf) in Scania, Sweden, but also at the Copenhagen University in Denmark. Vavilov did not recognize Scandinavia as part of a center of origin of cultivated plants. It was only after World War II, when P.M. Zhukovsky, a scholar of N.I Vavilov, developed the concept of mega-centers of diversity of cultivated plants, that Scandinavia became part of what he termed the European-Siberian Region of Diversity. We list species domesticated in Scandinavia or Northern Europe, and we further discuss concepts related to crop evolution and highlight the great impact Vavilov has had by inspiring scientists across disciplines and over many decades.

Free-Grazing versus Enclosure Lead to an Increase in the Germination of the Leymus chinensis Seed Bank in the Hulunbuir Grassland

Leymus chinensis is a primary plant in the meadow steppe and typical steppe of China. With global warming and increasing grazing intensity, grassland degradation is being exacerbated. To better protect the L. chinensis grassland in this area and provide a theoretical basis for restoring it, this paper compared the germinable seed bank in the soil and the germination characteristics of L. chinensis (including initial germination time, duration of germination, germination termination time, germination dynamics, and germination index) in free-grazing and enclosed areas. At the same time, combining information about the density of L. chinensis on the ground and previous research results, a comprehensive analysis was conducted. The major results were: (1) there was no significant difference in the number of germinable seeds in the soil between the free-grazing area and the enclosed area, and these seeds were mainly concentrated in the 0–2 cm soil layer. (2) The free-grazing area resulted in a significant increase in the number of germinable L. chinensis seeds and advanced the initial germination time. (3) The number of soil germinated seeds and the number of L. chinensis germinated seeds decreased with the increase in soil depth. (4) Livestock grazing behaviours increased seed burial, thus improving the L. chinensis germination rate. At the same time, the L. chinensis seed bearing percentage and seed quality and the number of germinable L. chinensis seeds were significantly higher in the free-grazing area than in the enclosed area. However, this result still needs to be further explored.

Morphological Characterization and Evaluation Of Snake Gourd Genotypes for Fruit Yield, Yield Attributes and Other Characters

The experiment was conducted at the research field of Horticulture Department of Bangabandhu Sheikh Mujibur Raman Agricultural University (BSMRAU) during the period from March to June 2017 to characterize and evaluate the snake gourd genotypes morphologically. In the study, 55 snake gourd genotypes collected from Plant Genetic Resources Centre (PGRC) of Bangladesh Agricultural Research Institute (BARI), Genetics and Plant Breeding Department of BSMRAU, different seed companies and various parts of Bangladesh. The genotypes exhibited 67.3% cylindrical, 21.8% elliptical, 1.8% fusiform, 9.1% ovate shape fruit along with 56.4% green, 18.2% light green, 16.4% dark green and 9.0% white fruit. Seed colour with 38.2% was brown and 83.6% seed shape was elliptical. The fruit length varied from 12 to 54 cm while fruit diameter varied from 3.5 to 5.5 cm. Days to 1st female flower opening ranged between 44 and 62 days and nodes number on female flower initiation was between 12 and 26. Days to 1st fruit harvest varied from 54 to 72 days. The number of fruits/plants ranged from 8.33 to 27, whereas individual fruit weight varied from 90 to 325g. Fruit yield/plant ranged from 1.29 to 7.74 kg. Genotypes were TC01, TC03, TC04, TC05, TC07, TC08 and TC19 identified as early maturity. The genotypes differed significantly in most of the parameters and offer a good scope for selection of parent for crop improvement programme.&#x0D; Bangladesh J. Agril.

The eternal return: Imagining security futures at the Doomsday Vault

This article examines how imaginaries of security in the Anthropocene function at the Svalbard Global Seed Vault (SGSV), otherwise known as the ‘Doomsday Vault’. Recent explorations by scholars of security have suggested that different ways of seeing, understanding, acting in, and imagining the world are necessary to adequately respond to complex crises in the Anthropocene. The dissolution of the nature/culture divide and the existential risk from planetary threats are said to require new and creative formations of security. Buried in the Norwegian high Arctic, the heavily fortified SGSV was built in 2008 as a planetary-scale, ‘deep-time organisation’ that would forever secure a wide variety of plant seeds and their genetic makeup against regional or global upheavals. The article argues that his seed ‘ark’ materialises three Anthropocene security imaginaries: apocalypse, hope and escape. The prevalence and use of these imaginaries reveal the stability of long-held security logics and challenge the widely-held belief in the innately transformative properties of the Anthropocene concept for security. Instead, the SGSV demonstrates the difficulty in overcoming a collective mindfulness that fixes security to eternal forms even in the midst of unprecedented threats, interventions and technology.

Maize Rotation Combined with Streptomyces rochei D74 to Eliminate Orobanche cumana Seed Bank in the Farmland

Orobanche cumama wallr. is the sunflower root parasitic weed with special life stage in which seed germination and parasitism take place in the soil. In practice, applying microbial agents and trapping crop rotation are utilized separately, or just one of them is selected to control O. cumana. The development of the sunflower industry is severely constrained on the farmland, where there is high density of O. cumana’s seed banks. In this study, two biological control methods were combined to solve the problem of O. cumana parasitism. The bioassay experiment showed that the high concentration fermentation filtrates of Streptomyces rochei D74 could effectively inhibit the germination and growth of the germ tube of O. cumana seeds. As the concentration was increased to 3.1 mg/mL, O. cumana was almost unable to sprout. A two-year pot experiment revealed that the use of D74 agents and sunflower–maize–sunflower rotation together promoted sunflower growth, as shown by the biomass accumulation, plant height, and denser root systems. The combined method resulted in a significant decrease in the number of O. cumana parasitism, compared to one method alone. Additionally, it affected the bacterial community composition of sunflower rhizosphere, mostly leading to an increase in Streptomyces and Brevibacterium and a decrease in Arthrobacter. This experiment, combined with multiple biological control, means significantly reducing the parasitism of O. cumana, which provides an effective foundation for practical application.

Cost Analysis of Collection and Ex Situ Conservation of Seeds of Important Native Tree Species of Mexico

In Mexico, there are barely any studies that estimate the cost of germplasm conservation especially that carried out ex situ. The objective of this study was to analyze the collection and storage costs (CSC) of seeds of some native tree species that have social and economic importance in Mexico. Information on the importance of native trees was obtained through a literature review and research from a seed bank and forest technical service providers. Based on the environmental and social importance, as well as the conservation status of native species, poverty attention, and food security, an indicator of economic and social importance has been designed using multicriteria analysis. The highest value of the indicator included 32 species; Fabaceae was the most represented family (28%). The CSC analysis was applied to the species with the highest value indicator, currently available market price (CMP), and stored in the seed bank (SB). They were evaluated using the “cost of collection” method comparing CMP vs. SB. The cost of accession in the SB is 11 times higher than the CMP with 7% of nominal interest rate (NIR) and increases 24 times during a storage period of ten years with the same NIR per year. Despite the costs associated with the maintenance and management of SBs, their importance for conservation and contribution to society is highlighted.
