Constraints in the adoption of Allanblackia stuhlmannii (Engl.) Engl. as agroforestry tree in East Usambara, Tanzania

ABSTRACTNatural forests in the East Usambara Mountains provide villagers with several Non-Timber Forest Products. Useful trees are often retained when forests are converted to farmland. Allanblackia stuhlmannii is a common forest tree on farmland. Due to the high-quality seed oil, a wish to conserve the species and to provide farmers with income from seed sale, efforts have been made for large-scale production by smallholders. The strategy includes maintenance of existing trees on farmland and rejuvenation by planting. An adoptability survey was conducted among 225 seed collectors and farmers in 10 villages in East Usambara. Results showed that the traditional open fruit collection from farmland trees had become more restrictive. Adoption by farmers was slow. Although seeds were collected from standing trees, barriers to cultivation were long juvenile period, competition with crops, lack of space for tree planting and potential waste of land for male trees. The greatest obstacle was the preference for other tree species. Economic calculations showed that the production of Allanblackia seed was not competitive compared to clove and cinnamon. The study shows that although several NTFPs are collected, only Allanblackia was cultivated. The study questions whether Allanblackia cultivation, based entirely on smallholders, is sustainable.

A hybrid weed optimized coverage path planning technique for autonomous harvesting in cashew orchards

A coverage path planning algorithm is proposed for discrete harvesting in cashew orchards. The main challenge in such an orchard is the collection of fruits and nuts lying on the floor. The manual collection of fruits and nuts is both time consuming and labour intensive. The scenario begs for automated collection of fruits and nuts. There are methods developed in research for continuous crop fields, but none for discrete coverage. The problem is visualized as a graph traversal problem and paths for autonomous maneuvering are generated. A novel Mahalanobis distance based partitioning approach for performing coverage is introduced. The proposed path planner was able to achieve a mean coverage of 52.78 percentage with a deviation of 18.95 percentage between the best and worst solutions. Optimization of the generated paths is achieved through a combination of local and global search techniques. This was implemented by combining a discrete invasive weed optimization technique with an improved 2-Opt operator. A case study is formulated for the fruit picking operations in the orchards of Puducherry. The performance of the proposed algorithm is benchmarked against existing methods and also with performance metrics such as convergence rate, convergence diversity and deviation ratio. The convergence rate was observed to be 99.97 percent and 97.83 percent for a dataset with 48 and 442 nodes respectively. The deviation ratio was 0.02 percent and 2.16 percent, with a convergence diversity of 1.18 percent and 30.14 percent for datasets with 48 and 442 nodes. The achieved solutions was on par with the global best solutions achieved so far for the test datasets.

Testing Rensch’s rule in Acanthoscelides macrophthalmus, a seed-feeding beetle infesting Leucaena leucocephala plants

Rensch’s rule states that males vary more in size than females when body size increases. The main cause of Rensch’s rule has been credited to sexual selection. However, different degrees of plasticity between the sexes have also been proven to be useful for describing variations in sexual size dimorphism, particularly within an intraspecific context. For insects, in general, this rule has rarely been tested within species. Here, we tested whether Acanthoscelides macrophthalmus (Schaeffer, 1907) (Coleoptera: Chrysomelidae: Bruchinae) followed Rensch’s rule when individuals emerged from seeds immediately after fruit collection and when they were reared for one generation, by measuring three morphological traits. Rensch’s rule was not followed for any of the morphological traits. Variations in body size were similar in males and females for bruchines that first emerged from seeds and for those that were reared for one generation. These findings suggest that environmental conditions (e.g., temperature, humidity, and seasonality) are unlikely to drive differential plasticity in males and females of this seed-feeding beetle. It is possible that changes in the body size of A. macrophthalmus have a genetic basis. However, regardless of whether variations in body size have a genetic basis, our findings provide no support for Rensch’s rule.

Development of integrated loose fruit collector machine for oil palm plantations

Oil palm loose fruit have always been part of oil palm harvesting operation. The current manual loose fruit collection by hand picking or raking is contributing to the minimum productivity and large amounts of debris. Effort in future shall be explored for the potential machine or system to collect the loose fruit in the field with the result of clean loose fruit. A new machine for loose fruit collection is being developed and examined which knows as Integrated Oil Palm Loose Fruit Collection Machine for collecting loose fruit from the palm base. Consist of three main integrated stages; the suction stage is used to collect the loose fruit, followed by segregating stage, which used to segregate the loose fruit from debris through double layer rotating drum and unloading stage of loose fruit to the 3-4 metric tons bin by using hydraulic tipping cylinder. Result indicates that at least more than 50% productivity of loose fruit collection were increased. In addition, the clean loose fruit collection resulted with the debris less than 10%. Hence, with this development, better quality loose fruits are collected with minimum debris for further processing in the palm oil mill, which will contribute to better oil extraction rate.

Can exotic drosophilids share the same niche of the invasive Drosophila suzukii?

The presence of the four exotic drosophilids Chymomyza amoena (Loew), Drosophila suzukii (Matsumura), Zaprionus indianus (Gupta) and Zaprionus tuberculatus Malloch has been investigated in different orchards in Northern Italy for two consecutive years. The presence and the abundance of the population of the drosophilid flies were surveyed with apple cider vinegar traps, fruit baited traps, and fruit collection. Chymomyza amoena, Z. tuberculatus and D. suzukii have been identified in the Apple Cider Vinegar traps in both years. Only D. suzukii and Z. tuberculatus emerged from fruit baited traps. Except for D. suzukii, no other exotic drosofilid was captured from the fruit collection. Z. indianus was never observed. Analyses of the presence of the different species, seasonal occurrence and sex ratio are provided.

TOCOPHEROLS OF FRUIT PULP OF FOUR SEABUCKTHORN (HIPPOPHAE RHAMNOIDES L.) SUBSPECIES IN FOREST-STEPPE CONDITIONS OF ALTAI TERRITORY

The aim of the study was to study tocopherols in the fruits of various sea buckthorn ecotypes ssp. mongolica in comparison with other subspecies. The composition of tocopherols in fruit pulp of four subspecies of sea buckthorn – H. rhamnoides ssp. mongolica, ssp. turkestanica, ssp. fluviatilis and ssp. carpatica, growing at Lisavenko Research Institute of Horticulture for Siberia in forest-steppe conditions of Altai territory has been studied. The research has been focused on the most promising subspecies from the point of view of industrial utilization – H. rhamnoides ssp. mongolica, in order to identify possible variation in accumulation of different tocopherols in fruit pulp depending on ecotype, period of collection of fruits as well as conditions of the year.
 It was established that the major tocopherol in the pulp of the fruit of sea buckthorn is α-tocopherol. β -, γ-and δ-tocopherols were characterized by low content. Within subspecies H. rhamnoides ssp. mongolica most fractions of tocopherols (except δ-tocopherol) have relatively high coefficient of variation, which exceeds of that for the whole group of evaluated varieties. That result does not allow us to use this criteria as a reliable background for preliminary systematic identification of evaluated varieties.

Food mobility and the evolution of grasping behaviour: a case study in strepsirrhine primates

Manual grasping is widespread among tetrapods but is more prominent and dexterous in primates. Whether the selective pressures that drove the evolution of dexterous hand grasping involved the collection of fruit or predation on mobile insects remains an area of debate. One way to explore this question is to examine preferences for manual versus oral grasping of a moving object. Previous studies on strepsirrhines have shown a preference for oral grasping when grasping static food items and a preference for manual grasping when grasping mobile prey such as insects, but little is known about the factors at play. Using a controlled experiment with a simple and predictable motion of a food item, we tested and compared the grasping behaviours of 53 captive individuals belonging to 17 species of strepsirrhines while grasping swinging food items and static food items. The swinging motion increased the frequency of hand-use for all individuals. Our results provide evidence that the swinging motion of the food is a sufficient parameter to increase hand grasping in a wide variety of strepsirrhine primates. From an evolutionary perspective, this result gives some support to the idea that hand-grasping abilities evolved under selective pressure associated with the predation of food items in motion. Looking at a common grasping pattern across a large set of species, this study provides important insight into comparative approaches to understanding the evolution of the hand grasping of food in primates and potentially other tetrapod taxa.

Insights into the bioactive compounds, antioxidant potential and TLC profiling of different extracts of Tomato plants

Tomato (Solanum lycopersicum L.) is a widely cultivated vegetable crop worldwide and its consumption is increasing day by day. The only edible part of tomato plant is its fruit. Therefore, the residual tomato plant parts are considered as waste after fruit collection despite some portion of it is used as livestock feed and in the production of fertilizer. Moreover, due to the consumption issue, much of the research is focused on tomato fruit rather than other plant parts. Bioactive compounds can be present in any part of the plant and can be isolated and recovered. Therefore, tomato plant may be useful as a source of bioactive compounds. Our study focuses on the phytochemical constituents and bioactive compounds that are present in different parts of the tomato plant that were being less studied before. Qualitative phytochemical tests were performed to identify the presence of different bioactive compounds. Saponins, tannins, glycosides, phenols, alkaloids, flavonoids and resins are present in significant amount. Total phenol, total flavonoids, total tannin, and total protein content were measured quantitatively. Leaf samples showed higher concentrations of bioactive compounds than roots and stem. Highest total phenol content (66.43 mg/g), total flavonoids content (28.00 mg/g), total tannin content (7.36 mg/g) and total protein content (26.55 mg/g) was found from the leaf water extract. DPPH scavenging assay was performed to find the antioxidant potential and positive results were found. Thin layer chromatography (TLC) was also employed to check the constituents. Our study found several spots for different samples and their retention factors (Rf) were evaluated.

The evaluation of lipids raw material resources with the fatty acid profile and morphological characteristics of Idesia polycarpa Maxim. var. vestita Diels fruit in harvesting

Idesia polycarpa Maxim. var. vestita Diels (further referred as I. polycarpa), belonging to Salicaceae family, is a perennial woody plant. I. polycarpa seed and fruit are well known to be rich in oils, what’s more it is considered to be an industrially valuable oilseed plant grown in the subtropical and temperate regions. The aim of this paper is to systematically study the lipid content, fatty acid profile of oil and morphological characteristics of the I. polycarpa fruit collected from various regions in China. The degree of the changes in oil content and fatty acid composition is also compared for its better industrial application as a source of linoleic acid. Our study found that the sum of the oil content of the pulp and the seed was not significantly different from the oil content of the entire fruit. The present work focuses on the integral use of I. polycarpa fruit. The morphological characteristics of fruits were systematically studied, including fruit shape index, fruit dry biomass, seed number per fruit, seed dry biomass, pulp dry biomass. Gas chromatograph with a mass detector (GC/MS) analysis of fatty acid composition of fruit, pulp and seed were carried out separately. At the same time, we also carried out a correlation analysis between climatic conditions, fruit morphological characteristics and fatty acid composition. The results showed the dry weight, the seed number per fruit, and the seed dry weight are positively correlated with the oil content. The oil content of the fruit from different regions ranged from 21.27 ± 0.83% to 39.47 ± 0.32%. In fruit oil, linoleic acid is the main fatty acid. The linoleic acid content in all regions is above 60%, which is not correlated with the size of the fruit. Our results indicated that I. polycarpa is a potential woody oil plant rich in linoleic acid, which has multiple industrial applications, such as the production of alkyne resin, shoe polish, and the preparation of conjugated linoleic acid as well as varnishes. The results of the study could help us to use targeted fruit collection during fruit ripening and guide us to use the fruit for developing industrial products preparation.

Short Communication: Exploration of bidara laut (Strychnos lucida) parent trees in Gunung Tunak Ecotourism Park, West Nusa Tenggara, Indonesia

Abstract. Setyayudi A, Krisnawati, Nandini R. 2019. Short Communication: Exploration of bidara laut (Strychnos lucida) parent trees in Gunung Tunak Ecotourism Park, West Nusa Tenggara, Indonesia. Biodiversitas 20: 374-378. Bidara laut (Strychnos lucida R. Brown) is one of the widely used medicinal plants. There is a bidara laut wood processing industry in West Nusa Tenggara that produces drinking cups called ‘health cups’ utilizing bidara laut. All raw materials used for the production of health cups are, however, obtained from bidara laut stands in forest areas, which may cause the extinction of this medicinal plant species if the highly intensive raw material harvesting in the forest is not supported with cultivation of this plant species. To preserve this plant species, the Institute for Research and Development of Non-Timber Forest Products Technology (NTFP-RDI) has carried out breeding activities by developing a collection garden of this species from the populations of Bali and West Nusa Tenggara (Lombok and Sumbawa Islands). The initial step carried out was the exploration of the parent trees followed by collection of generative materials (seeds) and nurseries. Exploration of bidara laut parent trees on Lombok Island was carried out in Gunung Tunak Ecotourism Park using a purposive sampling method, followed by collection of fruits to obtain seed propagating materials for establishment of seedling nurseries. Twenty-five parent trees were identified with average height of nine m, stem diameter of 24 cm and stem straightness scales of 1-3. The average seed produced was 413 seeds tree-1. Three parent trees were selected based on the highest seed germination rates, namely parent trees number 6, 14 and 20. This result provides useful information for the next bidara laut breeding activities.

Socio-economic factors influencing land-use and land-cover changes in the miombo woodlands of the Copperbelt province in Zambia

This study examined socio-economic factors that influence land-use and land-cover dynamics in the Copperbelt miombo woodlands of Zambia. Data were collected through household surveys and focus group discussions. All households that have lived in the area for 5 years and above were considered eligible to participate in the survey. A total of 372 households and 30 discussants within a 5-km buffer zone of the forest reserves were selected for interview. Pearson's Chi-square tests were used to test association between independent variables (gender, age, education, wealth status, and household size) and use of forest products. Furthermore, binary logistic regression models were developed to examine determinants of forest products use and land-use and land-cover change. The chi-square results revealed a strong association among the following; charcoal production with gender, age and wealth; use of construction poles with household size; firewood collection with wealth; wild fruits collection with gender and household size; caterpillar collection with education; honey harvesting with gender and wealth; wild vegetable collection and use with education; use of thatching grass with wealth and household size; livestock fodder use with wealth and level of education; collection and use of bush meat with age and residence status; collection of material for brooms with age and wealth respectively. The logistic regression model results revealed that charcoal, construction poles, wild fruits and animal fodder were statistically significant at 1% level while, honey, thatching grass and bush meat were significant at 5%. Gender, age, education, wealth status, household size and residence status were significant determinants in the use of various forest products. Furthermore, the regression model showed that agriculture expansion (p < .031) and population growth (p < .032) were significant determinants of changes in forest cover. The study concludes that there is high level of dependence on forest products by local communities and hence any attempts to avert deforestation should consider addressing social and economic problems faced by local communities. We further conclude that development of sustainable forest management policies and strategies that provide for inclusion of local ecological knowledge and various utilization practices such as charcoal production into sustainable forest management.

Towards Sustainable Livelihood Practices in the Indigenous Forests of Zambia’s Central Province: Barriers and Opportunities

This study was designed with the aim of establishing a comprehensive picture of the problems and needs of local communities in upholding sustainable livelihoods in the face of forest degradation and recommending how their livelihoods may be improved in the short and long term.&amp;nbsp; Thus make them self-reliant by enhancing their resilience.&amp;nbsp; Study Methodology: included a literature review and a household survey for a total of 443 household interviews. In addition, Focus Group Discussions (FGDs) and Key Informant Interviews (KIIs) were conducted with the rural population and other stakeholders respectively. Field visits were made to all the 8 sites in the two districts Serenje and Chitambo. The main constrain of sustainable livelihood in the communities, included, low levels of education and skills, low levels of asset holding, weak local institutions and unfavorable legal and institutional frameworks. But the respondents registered a wide variety of NTFPs based livelihoods obtained from forests resources (15). Most important usage includes land for cultivation, fuelwood, poles for construction, charcoal production and use of NTFPs (collection of mushrooms, wild fruits and nuts, caterpillars, honey production and medicinal plants). The livelihood activities remains largely subsistence and for safety net functions. Trade resulting into incomes generation is minimal, unstructured and therefore unsustainable. In conclusion: commercialization of NTFPS and PES activities may be the solution to sustainable livelihood and forest conservation. A range of specifically forest sector elements would also need to be addressed, including, entrepreneurship, market and skill development for forest product and services delivery; embracing these elements will also require new kinds of enhanced institutional arrangement.

Infestation and timing of use of non-crop plants by Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) in the Okanagan Basin, Canada

AbstractDrosophila suzukii (Matsumura) (Diptera: Drosophilidae), was first detected in 2009 in the Okanagan Basin, British Columbia, Canada. During 2010–2016, 94 570 fruits of 35 non-crop species, from 12 plant families, were collected from 101 sites where adult D. suzukii flies were trapped, and incubated in a controlled environment. In total, 450 adult D. suzukii emerged from 62 of 929 fruit collections, and from 10 host plant species in five families, of which six species are native to the region. Five plant species are reported for the first time as hosts of D. suzukii, and 11 species for the first time as non-hosts. Measures of fly occurrence and infestation reveal it to be relatively abundant in five hosts and low in others. The fly reproduced in a succession of host plants, with first infestation of each from mid-July through mid-September, and was present until mid-October, but overwintering stages were not found. Degree-day accumulations for the infested period suggest that three to five generations of D. suzukii developed on non-crop plants and formed a large contribution to the annual increases observed in trap counts in a semi-arid cold winter climate, with implications for many strategies of pest management.

Propiedades fisicoquímicas de guayabilla (Psidium guineense), arrayán (Psidium sartorianum) y guayaba (Psidium guajava)

A fin de determinar la posible utilización de guayabilla (Psidium guineense) y arrayán (Psidium sartorianum) en la innovación para la generación de productos alimenticios, las propiedades fisicoquímicas de frutos de estas especies fueron comparadas con las de guayaba (Psidium guajava). Para esto, se seleccionaron cinco sitios de colecta de fruta las especies silvestres en el municipio de Talpa, Jalisco. La hipótesis planteada fue que los niveles de ácido cítrico e índice de maduración podrían ser superiores en guayabilla y arrayán, mientras que el contenido de azúcar podría ser mayor en guayaba. El diseño experimental utilizado fue un completamente al azar con un número de frutos que varió en función de los árboles de las especies presentes en cada sitio. Las medias obtenidas fueron comparadas mediante la prueba de Tukey p= 0.05. La acidez observada en frutos maduros de P. sartorianum y P. guineense osciló entre pH 2.84 a 3.21, mientras que en guayaba se observó un pH 4.13 (menos ácida). La acidez titulable obtenida fue congruente con el pH, pues a mayores valores de acidez titulable corresponden los menores valores de pH. A pesar de la acidez de los frutos de P. sartorianum, uno de los sitios de colección mostró un índice de solidos solubles totales (7.4 °Brix) superior al de guayaba (5.32 °Brix). El índice de maduración fue superior para guayaba, en contraste a los valores bajos encontrados en P. guineense y P. sartorianum. Finalmente, P. guajava presentó frutos más grandes que las dos especies silvestres.

Genetic analysis of a major international collection of cultivated apple varieties reveals previously unknown historic heteroploid and inbred relationships.

Domesticated apple (Malus x domestica Borkh.) is a major global crop and the genetic diversity held within the pool of cultivated varieties is important for the development of future cultivars. The aim of this study was to investigate the diversity held within the domesticated form, through the analysis of a major international germplasm collection of cultivated varieties, the UK National Fruit Collection, consisting of over 2,000 selections of named cultivars and seedling varieties. We utilised Diversity Array Technology (DArT) markers to assess the genetic diversity within the collection. Clustering attempts, using the software STRUCTURE revealed that the accessions formed a complex and historically admixed group for which clear clustering was challenging. Comparison of accessions using the Jaccard similarity coefficient allowed us to identify clonal and duplicate material as well as revealing pairs and groups that appeared more closely related than a standard parent-offspring or full-sibling relations. From further investigation, we were able to propose a number of new pedigrees, which revealed that some historically important cultivars were more closely related than previously documented and that some of them were partially inbred. We were also able to elucidate a number of parent-offspring relationships that had resulted in a number of important polyploid cultivars. This included reuniting polyploid cultivars that in some cases dated as far back as the 18th century, with diploid parents that potentially date back as far as the 13th century.

Study on characteristics and microscopic identification of fruits of Notopterygium franchetii and N. forrestii

Rhizoma et Radix Notopterygii is a rare and endangered Chinese medicine. In the collection of Notopterygium franchetii fruits, we collected a sample of N. forrestii , which is a spurious breed. Fruits of N. franchetii and N. forrestii are very similar in morphology and can be easily confused. Until now the morphological identification of the fruits of Notopterygium has not been reported. To provide a scientific basis for the identification of N. franchetii and N. forrestii fruits, the morphology and microscopic identification were studied in this paper. In this study, stereomicroscope and paraffin sections were used to compare the morphological characteristics and microscopic characteristics of these two fruits. Our results showed that these two fruits were different in size, surface texture and the number of vertical edges on the back. These traits can be used as diagnostic characteristic of these two fruits. The difference between the number of tubing and the endosperm cell contents can be used as microscopic identification features. The above discriminative characteristics can distinguish the two fruits and provide scientific basis for the identification and germplasm evaluation of Notopterygium fruits.

Impacts of water availability on macronutrients in fruit and leaves of conilon coffee

Abstract: The objective of this work was to evaluate the concentrations and accumulation of macronutrients in conilon coffee (Coffea canephora) fruit, and their concentrations in leaves, over two years, in irrigated and nonirrigated coffee plants. Three-year-old conilon coffee plants of the cultivar Emcapa 8111 genotype 02 were used. An experimental design was carried out in randomized complete blocks, in a split-plot arrangement, with 14 replicates. The main plot factor was irrigation versus nonirrigation of coffee plants, and the split-plot factor was different fruit and leaf collection times. Collections began 10 days after the beginning of flowering and were performed on average every 28 days, until full fruit ripening. At each sampling date, five plants per treatment were picked out, by collecting one plagiotropic branch by plant, separated into fruit and leaves. Each part was dried, weighed, and subjected to the chemical analysis. Macronutrient accumulations and their accumulation rates were determined. According to the regression analysis of the data, fruit macronutrient accumulation curves fit best to sigmoidal equations. Irrigation affects the macronutrient dynamics in fruit and leaves during the fruiting phase of conilon coffee, and increases the accumulation of nutrients in the plant tissues. The macronutrients found in greater quantities are N, K, and Ca, in fruit and leaves, regardless of the irrigation treatment.
