Vegetative propagation of elite Eucalyptus clones as food source for honeybees (Apis mellifera); adventitious roots versus callus formation

Summer and autumn in Israel are highly arid with not enough plants in bloom offering nectar and pollen to support the local apiary. This leads to decline in colony health and honey production. To increase food sources for honeybees, we initiated a project to clone elite Eucalyptus trees exhibiting constant and rich blooming from late summer to early winter. We induced adventitious roots from cuttings of two mature Eucalyptus trees of which nectar production and honeybees’ attraction was measured: Eucalyptus brachyphylla and Eucalyptus x trabutii. During the rooting process, a high frequency of cylindrical callus formation instead of roots was obtained. To shed light on the inner anatomy of the callus chunks, we compared their cell organization and cell-wall composition to those of roots. Whereas in the root, cells were organized in circumferential symmetry, no symmetry was found in the callus. Instead, a more chaotic accumulation of meristematic-like cells with sporadic clusters of tracheary elements laid in different directions were observed. The outer cell layer of the callus often included swollen cells with thin cell walls. Most callus cells stained more strongly for cellulose and lignin than cells in the root meristem. In addition, specific antibodies to methylesterified and de-methylesterified pectin showed differential staining of callus vs. root cells indicating cell wall differences. Strikingly, roots were seen to differentiate from the chaotic cell organization of the callus, albeit at low rates. Further investigation of the cellular and molecular mechanisms underlying callus formation, are required.

Assessment of Chrysoperla comanche (Banks) and Chrysoperla externa (Hagen) as Biological Control Agents of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) on Tomato (Solanum lycopersicum) under Glasshouse Conditions.

We tested the predatory capacity of newly-hatched or newly-molted Chrysoperla comanche (Banks) and Chrysoperla externa (Hagen) larvae after a 24 h fasting period on adults of Frankliniella occidentalis (Pergande) that were feeding on tomato plants (at vegetative and blooming stage) under glasshouse conditions. We also recorded fruit damage by the thrips. Both Chysoperla spp. depredated a similar number of F. occidentalis (thrips) adults regardless of the phenological stage of the plant. Second and third instar larvae of both species consumed significantly more thrips than first instar during plant blooming, however when the plant was at vegetative stage, all larval stages of both species predated a similar number of thrips. A significantly lower fruit damage percentage was recorded at the blooming plant when C. comanche larvae were in the experimental cage, however the presence of second and third instar of both species significantly reduced the fruit damage. No foliar damage was recorded. As far as we know, this is the first assessment of the predatory capacity of C. comanche and C. externa on thrips feeding on tomato under glasshouse conditions.

СЕВЕРОАМЕРИКАНСКИЕ ВИДЫ РЯБИН (SORBUS L.) КОЛЛЕКЦИИ ЮЖНО-УРАЛЬСКОГО БОТАНИЧЕСКОГО САДА

A brief description of three North-American species of rowan trees from the collection of the South-Ural Botanical Garden-Institute of Ufa Federal Research Centre of Russian Academy of Sciences (UFRC RAS): Sorbus decora, Sorbus americana and Sorbus scopulina is given. The climatic conditions of introduction area are similar in temperature to the parameters of the natural range of the North American S. decora: they are not optimal for it, but the plants bloom and give viable seeds. It can be assumed that vital signs of S. decora would be higher in milder climate and favorable water-physical soil conditions. According to the analysis of variance, it is revealed that the conditions of the year and species characteristics significantly affect all the phenological phases of development of North American rowan trees. At the same time, they are more dependent on the temperature conditions of the year (F=17.4 at p<0.001) and less on species characteristics (F=6.2, at p<0.001), although the sequence of phenophases is maintained from year to year. The average vegetation period of rowan trees is 154–163 days. S. decora growing in the Botanical Garden for a long time (planted in 1960–1974) and relatively new species for the collection – S. mericana and S. scopulina (2009–2013) can be considered promising decorative crops for growing in the climatic conditions of Ufa and the Bashkir Urals

Genetic improvement of bougainvillea in Indian scenario - A review

Bougainvillea is a native of South America and it is a popular plant all over the world with tropical and warm climates. It is a thorny and woody plant having different coloured bracts viz., white, pink, purple, red, orange, yellow etc. Among the different species of Bougainvillea, Bougainvillea glabra and B. spectabilis are most popular across the world. Bougainvillea plants provide colour to the garden when the flowering of winter season annuals ceases and the blooming of summer annuals or other ornamental plants is yet to arrive. The ability of bougainvillea to grow under highly polluted conditions like traffic islands, roadsides and around industries has made it popular among the planners and architects. The plants can be grown as climbers by training them on walls of house or any building, parks, farms garden, open spaces and on arches or pergola or on a tree. The edible flowers of Bougainvillea are frequently used for the preparation of salads and flower teas in different parts of the world. The floral bracts are the rich source of betalain pigments particularly betacyanin which can be exploited as a natural colorant in food industries. Although, Bougainvillea has originated in South America, but approximately 50% of the present day cultivars were evolved and developed in India. The Division of Floriculture and Landscaping of IARI is a pioneering centre of Bougainvillea and have a good collection of germplasm of bougainvilleas. Besides, NBRI, Lucknow; IIHR, Bangalore; CAZRI, Jodhpur and BARC, Mumbai have contributed significantly in breeding of Bougainvillea. Division of Floriculture and Landscaping IARI, New Delhi has been recognized as the International Registration Authority for Bougainvilleas by Royal Horticultural Society, U.K, since, 1966 and again during the recent meeting of 2007 held at Wageningen, The Netherlands. The division is one of the major repository centre and more than 100 cultivars of Bougainvilleas are conserved here with different colour, thorny, thornless, variegated, bicoloured, multibracted etc. The varieties evolved at IARI include Dr. R.R. Pal, Stanza, Summer Time, Sonnet, Spring Festival and Vishakha.

Development of Growth Models Based on Years for Salep Orchid Planted in Natural Environment

Abstract The orchids that produced tuber are known as salep orchids and have been collected from nature for centuries as a medicinal and aromatic plant. These orchids are endangered species because of their limited vegetative and generative production possibilities. Salep orchids, seed germination has been achieved with in-vitro studies, but no source has been found regarding the development of germinated seeds over the years. In this study, Dactylorhiza euxina (Nevski) Czerep. was used as research material. Seeds that were determined to germinate in nature were observed to develop in their own environment for five years and some morphological characteristics (plant height, number of leaves, leaf length, leaf width, total weight, tuber width, and tuber weight) were determined at the end of each vegetation year. Plants that start to develop with seed germination produce one leaf and a tuber of 0.115 g in the first year. When the tubers obtained from the first year were planted again, the plants was obtained 2-3 leaves and they were formed 0.465 grams of tubers. In the third year plants bloom for the first time. The period until flowering in the plant was called maturity period and Dactylorhiza euxina (Nevski) Czerep. was found to have a 3-year maturity period. Plants produced tuber 0.850 g in the third year, 1.585 g in the fourth year and 2.522 g in the fifth year. According to the mathematical modeling, the relationship between year (Y) and fresh tuber weight (FTW) was found Y = 1.22 + (1.61 × FTW) and there was a significant relationship among year, fresh tuber weight, and total biomass (TBM). This equation Y = 1.05 + (0.76 × FTW) + (0.14 × TBM) shows us the mathematical relations of year, fresh tuber weight, and total biomass. The mathematical relations among to fresh tuber weight, total biomass, and plant height (PH) was produced Y = 1.74 - (0.11 × FTW) + (0.57 × TBM) - (0.09 × PH). R2 values were found 0.95-0.99. All R2 values and standard errors were found to be significant at the p < 0.01 level.

Role of Growing Medium in Yield and Quality of Anthurium: A Review

Anthurium belongs to family Araceae and is highly praised flowering plant for its colourful long lasting unique flower and shining foliage. It is also an excellent plant for interior and as cut flower, especially for flower arrangement. The most suitable part of anthurium is modification of the leaf and botanically known as ‘spathe’. Heart shaped spathe emerges on the long flower stalk with a spadix. This plant blooms almost continuously under suitable conditions. It is epiphytic in nature with climbing, creeping and arboreous stems including many aerial roots that aid in taping water and nourishment. Quality and productivity of anthurium flowers depends on the growing medium. Most of the anthurium growers prepare own their growing media, but they do not know that the low productivity and quality might come from an poor potting mixture that they are using. One of the most important components of anthurium cultivation is the choice of growing substrate or medium. It is known to grow best in a well aerated medium with good water retention capacity and drainage. A good medium needs to be able to anchor the roots and stems so that the plant will not topple over as it grows larger, yet it should provide sufficient moisture, nutrient and aeration to the plant. The objective of this review is to present a summary of the influence of various growing medium on the growth, flowering, productivity and quality of anthurium grown in protected conditions. The results from the literature prove that the productivity of anthurium tends to be more in those plants which grown in different growing medium compared to soil grown plants.

Effect of Treatment of &lt;i&gt;Callistephus chinensis &lt;/i&gt;( L.) Ness. Plants by Ivin at Growth and Decorative Parameters in Conditions of Industrial City

The effect of the new growth stimulator with the cytokinin nature Ivin was investigated at the parameters of growth, blooming and chlorophylls content of the leaves of Callistephus chinensis (L.) Ness. plants. The researched plants grow under the impact of industrial and exhaust fumes. The intensification of the growth processes of the treatment plants in comparison with untreated was established. The processed specimens enhance height, the number of side shoots, quantity of the leaves and their area as well as the area of the total assimilation plants surface with increasing of the vegetative mass of the plants accordingly. At the same time, the number of inflorescences and their average diameter increase. There was no significant difference in essential influence of the biostimulator upon the plants of Callistephus chinensis between breeds ‘Victoria Sharlachovaya’ and ‘Strausovo pero Rubinivaya’ with the exception of some variables (total assimilation surface). The content of chlorophyll in leaves of Callistephus chinensis plants increases under spraying by Ivin. The rising occurs originally after spraying seedlings due to chlorophyll, after the third treatment (flower-bud formation) – due to both forms of chlorophylls was established, as well as the breed specific reaction of plants was determined. The novelty of this work consists in the investigation of the influencing the growth stimulator on the development of the ornamental flower plants in the conditions of environmental pollution. The treatment of this preparation is appropriate for stimulation of growth and intensity of bloom of the ornamental flower plants of urban territories.

MEDICINAL PLANTS OF BULGARIA

Bulgaria is a small country in Southeast Europe, but its geographic location, vari ed relief and climate contribute to great floristic diversity. The medicinal plants are part of it . They represent 23.2% of the country's flora. The aim of the present paper is to present information about the full composition of the medicinal plants of Bulgarian flora as well as characteristics of the systematic structure and classification according to biological type, life form, floristic geolements, period of flowering, and ecological groups. The complete list of medicinal plants in Bulgaria was compiled on the basis of the Medicinal Plants Act, extensive literature analysis and own researches. The life forms were identified according to Raunkiaer and for floral elements the classification of Walter was used. The ecological forms were identified according to Flora of Republic Bulgaria . As a result of the conducted surveys it was found that there are 950 medicinal species of vascular plants in the country belonging to 468 genera and 126 families. The richest family containing medicinal plants was Rosaceae (98 specie). The most medicinal plants exist ed among perennial herbaceous plants (539 species). Geoelements with a European component were predominated (408 species). The most plants bloom from June to August (121 species). The ecological structure of medicinal plants shows that mesophytes (435 species); heliophytes (545 species) and thermophylous plants (607 species) were dominated. The results of the study include also a detailed information about the national and international conservation importance of the analyzed species. 65 species were included in the Red Book of Bulgaria. There were 81 species protected by the Biodiversity Law. Among the medicinal plants are 16 Balkan and 4 Bulgarian endemic spesies. The international significance of these plants was defined by the fact that 33 of species were under protection by different international conventions. The ratio between the biological types, the predominant geoelements and the life forms shows is typical for the temperate continental climate zone and the flora of our country. The total percentage of protected species (7%) is not high, which is positive because most species are subject to use by the local population, the pharmaceutical and perfumery industry.

Creating Rare Species Artificial Populations of the Genus Hedysarum L. (Fabaceae)

In connection with the intensive mineral resource development, it is now topically relevant to 3cinserve the gene pool of plant rare species, whose populations find themselves within the exclusion zones (quarry mining, disposal of overburden and waste rocks, etc.). However, methods for moving plants from such zones to safe places in order to create artificial populations are still poorly developed. In Bashkortostan, tests are being undertaken to develop the methods for creating rare species artificial populations, including tick trefoils, such as Hedysarum grandiflorum Pall. and H. razoumovianum Fisch. et Helm. These species are included into the Red Data Books of the Republic of Bashkortostan and the Russian Federation. The works are being performed in the Natural Botanical Garden (natural protected area “Gurovskaya Gora” near Ufa). The aim of the research is to develop the methods for evacuating rare species and to create artificial populations and source nurseries for obtaining seeds and planting materials in order to conduct reintroduction works in the crucially endangered populations. In the test with H. grandiflorum we used 15 specimens from different places of Bashkortostan, among them from two sites where mining works are planned to be launched. The number of testing plots created since 2006 is 53. Seedlings are recorded during the first 4-6 years of observation. A massive loss of young plants is observed. Generative plants and self-seeding occur in the majority of the tests. Six specimens of H. razoumovianum are under investigation. Starting in 2005, 17 tests have been undertaken. Seedlings are recorded during 4-6 years. Generative plants emerge in the fourth or fifth year of observation. These plants bloom, produce fruits and self-seed every year. By 2014, two self-reproducing micropopulations have been formed. In 2017, 487 plants were recorde4d in one of them, with 24 maternal plants. The tests suggest the possibility to create artificial populations of these species and to conserve them under eco-phytocoenotic conditions comparable to those in nature. Even now they can serve as the seed source for the reintroduction works.

Draft Genome Sequence of Pseudomonas sp. Strain M7D1, Isolated from the Rhizosphere of Desert Bloom Plants.

We announce the draft genome sequence of Pseudomonas sp. strain M7D1, isolated from the rhizosphere of a plant in the Atacama Desert bloom event. The genome sequence had 6,170,633 bp with a G+C content of 59.9%. This draft genome sequence gives information about the presence of genes related to iron acquisition, alleviation of abiotic stress, and other essential traits of plant growth-promoting rhizobacteria.

Male and female bees show large differences in floral preference

BackgroundIntraspecific variation in foraging niche can drive food web dynamics and ecosystem processes. In particular, male and female animals can exhibit different, often cascading, impacts on their interaction partners. Despite this, studies of plant-pollinator interaction networks have focused on the partitioning of the floral community between pollinator species, with little attention paid to intraspecific variation in plant preference between male and female bees. We designed a field study to evaluate the strength and prevalence of sexually dimorphic foraging, and particularly resource preferences, in bees.Study designWe observed bees visiting flowers in semi-natural meadows in New Jersey, USA. To detect differences in flower use against a shared background of resource (flower) availability, we maximized the number of interactions observed within narrow spatio-temporal windows. To distinguish observed differences in bee use of flower species, which can reflect abundance patterns and sampling effects, from underlying differences in bee preferences, we analyzed our data with both a permutation-based null model and random effects models.FindingsWe found that the diets of male and female bees of the same species were often dissimilar as the diets of different species of bees. Furthermore, we demonstrate differences in preference between male and female bees. We show that intraspecific differences in preference can be robustly identified among hundreds of unique species-species interactions, without precisely quantifying resource availability, and despite high phenological turnover of both bees and plant bloom. Given the large differences in both flower use and preferences between male and female bees, ecological sex differences should be integrated into studies of bee demography, plant pollination, and coevolutionary relationships between flowers and insects.

Non-native honey bees disproportionately dominate the most abundant floral resources in a biodiversity hotspot.

Most plant-pollinator mutualisms are generalized. As such, they are susceptible to perturbation by abundant, generalist, non-native pollinators such as the western honey bee ( Apis mellifera), which can reach high abundances and visit flowers of many plant species in their expansive introduced range. Despite the prevalence of non-native honey bees, their effects on pollination mutualisms in natural ecosystems remain incompletely understood. Here, we contrast community-level patterns of floral visitation by honey bees with that of the diverse native pollinator fauna of southern California, USA. We show that the number of honey bees visiting plant species increases much more rapidly with flower abundance than does that of non-honey bee insects, such that the percentage of all visitors represented by honey bees increases with flower abundance. Thus, honey bees could disproportionately impact the most abundantly blooming plant species and the large numbers of both specialized and generalized pollinator species that they sustain. Honey bees may preferentially exploit high-abundance floral resources because of their ability to recruit nest-mates; these foraging patterns may cause native insect species to forage on lower-abundance resources to avoid competition. Our results illustrate the importance of understanding foraging patterns of introduced pollinators in order to reveal their ecological impacts.

Climate Change Communication in the Midwestern United States: Perceptions of State Park Interpreters.

Parks and protected areas can be ideal settings for climate change communication since many visitors have an affinity for natural and cultural settings, and an interest in resource protection. However, climate-based education efforts in the Midwestern United States may need a slightly different approach since this region lacks obvious indicators, such as sea level rise and melting glaciers. Interpretation, an informal communication process designed to transmit scientific information to visitors in leisure-based settings, could be a useful strategy for engaging visitors in climate change discussions. Few studies have assessed perceptions of interpreters on this topic, much less, their willingness to communicate such information. To address this issue, a mixed methods approach (surveys, interviews, photovoice) was used to examine interpreters' perceptions of climate change and its impacts in Missouri State Park and Historic Sites. Although nearly 70% of interpreters were either alarmed or concerned about climate change, many of them were unsure about its causation. Interpreters report observing impacts such as flooding, earlier plant blooming, high temperatures, extreme weather, and invasive species, but were uncertain about attributing these impacts to climate change. Interpreters did not believe that visitors would be responsive to climate-based education per se but thought the topic could be addressed in pre-existing programs and activities. Rather than discussing complex science with visitors, interpreters felt more comfortable with conveying the significance of resources at their sites. Implications from this study include acknowledging multiple viewpoints, framing strategic messages, and developing place-based educational materials.

Study of the cluster composition of pollen particles entering the atmosphere during the bloom of anemophilic plants

КЛАСТЕРНЫЙ СОСТАВ ПЫЛЬЦЕВЫХ ЧАСТИЦ АТМОСФЕРЫ В ПЕРИОД ЦВЕТЕНИЯ АНЕМОФИЛЬНЫХ РАСТЕНИЙ

A study is made on pollen emission into atmosphere of 12 species of anemophilous plants (Betula fusca Pall. ex Georgi, Betula pubescens Ehrh., Ulmus pumila L., Corylus americana Marsh., Corylus avellana L., Stipa pennata L., Poa nemoralis L., Achnatherum splendens (Trin.) Nevski, Panicum virgatum L., Lolium perenne L., Avena sativa L., Setaria maximowiczii Tzvelev &amp; Prob.), exposed by the Central Siberian Botanical Garden, SB RAS. These plants are widely spread over the territory of the Russian Federation and produce great amounts of allergenic pollen. Estimated is the share of clusters of two and more pollen grains in the total number of pollen particles, entering the atmosphere upon blooming of plants of a given species. It is shown that although the anemophilous plants display morphological properties, that prevent the formation of clusters, substantial number of such clusters is recorded in all experimental series. In this case, the share of pollen grains could exceed 50% of the total number of pollen grains, entering the atmosphere.

Encapsulation of ginger ethanolic extract in nanoliposome and evaluation of its antioxidant activity on sunflower oil

Ginger (Zingiber officinale Roscoe) is a blooming plant in the Zingiberaceae family which is broadly utilized as a flavor or a traditional drug. The ethanolic extract of ginger (GE) in liposome is encapsulated in the present examination. The average size of the nanoliposomal GE (NGE) was 164.5 nm. The phenolic content of GE was measured by Folin–Ciocalteo reagent. The DPPH radical scavenging, reducing power of Fe(Ш) and total antioxidant activity assays were used to evaluate the antioxidant activities of GE and NGE contrasted with the synthetic antioxidant (BHT). The antioxidant activities of NGE were higher as compared to GE and BHT in all tests. Furthermore, in order to assess the effects of GE and NGE at 100–1000 ppm concentrations in deferring the oxidation procedure of sunflower oil, heat treatment tests (peroxide and thiobarbituric acid values) at 63 °C within a 12-day period were used. The peroxide and thiobarbituric acid values of NGE were lower than GE and BHT. The NGE at 1000 ppm concentration had the highest level of antioxidant activity. In conclusion, findings indicate that NGE can be securely utilized as a natural antioxidant agent instead of synthetic preservation additives for food and biological systems.

緑肥作物ハゼリソウにおけるハモグリバエ類（ハエ目：ハモグリバエ科）の土着寄生蜂相とネギハモグリバエ防除のためのバンカープランツおよびインセクタリープランツとしての利用の可能性

Phacelia tanacetifolia Bentham is known worldwide as a kind of insectary plant and is used in Japan as a green manure crop before Welsh onion planting. To explore the possibility of using P. tanacetifolia as a banker plant or an insectary plant for parasitoids of Liriomyza chinensis Kato, we investigated the seasonal abundance of agromyzid leafminers and their hymenopterous parasitoids on infested leaves and blooming flowers of P. tanacetifolia collected in Chiba Pref., Japan, in 2009, 2010, and 2012. We also investigated longevity increase in Diglyphus isaea（Walker）adults with a blooming P. tanacetifolia plant in the laboratory. Almost all agromyzid leafminers reared from leaves were Chromatomyia horticola（Goureau）. Twenty-one parasitoid species including seven species reported from L. chinensis mines by different authors in Japan were reared from leaves, and nine species including eight species reared from leaves were caught on flowers. The most abundant parasitoid species was D. isaea. In this study, Diglyphus crassinervis Erdös was reared from C. horticola for the first time in Japan. The longevity of D. isaea adults provided with a blooming plant and water was about 18 days at 24°C with a 16L : 8D photoperiod. The log-rank test, used to compare survival curves from the 2 treatments; with and without blooming P. tanacetifolia plant, showed a statistically significant difference between treatments. These results suggest that P. tanacetifolia has potential as a banker plant or insectary plant for parasitoids to control L. chinensis in Welsh onion fields.

Predicting plant attractiveness to pollinators with passive crowdsourcing.

Global concern regarding pollinator decline has intensified interest in enhancing pollinator resources in managed landscapes. These efforts frequently emphasize restoration or planting of flowering plants to provide pollen and nectar resources that are highly attractive to the desired pollinators. However, determining exactly which plant species should be used to enhance a landscape is difficult. Empirical screening of plants for such purposes is logistically daunting, but could be streamlined by crowdsourcing data to create lists of plants most probable to attract the desired pollinator taxa. People frequently photograph plants in bloom and the Internet has become a vast repository of such images. A proportion of these images also capture floral visitation by arthropods. Here, we test the hypothesis that the abundance of floral images containing identifiable pollinator and other beneficial insects is positively associated with the observed attractiveness of the same species in controlled field trials from previously published studies. We used Google Image searches to determine the correlation of pollinator visitation captured by photographs on the Internet relative to the attractiveness of the same species in common-garden field trials for 43 plant species. From the first 30 photographs, which successfully identified the plant, we recorded the number of Apis (managed honeybees), non-Apis (exclusively wild bees) and the number of bee-mimicking syrphid flies. We used these observations from search hits as well as bloom period (BP) as predictor variables in Generalized Linear Models (GLMs) for field-observed abundances of each of these groups. We found that non-Apis bees observed in controlled field trials were positively associated with observations of these taxa in Google Image searches (pseudo-R2 of 0.668). Syrphid fly observations in the field were also associated with the frequency they were observed in images, but this relationship was weak. Apis bee observations were not associated with Internet images, but were slightly associated with BP. Our results suggest that passively crowdsourced image data can potentially be a useful screening tool to identify candidate plants for pollinator habitat restoration efforts directed at wild bee conservation. Increasing our understanding of the attractiveness of a greater diversity of plants increases the potential for more rapid and efficient research in creating pollinator-supportive landscapes.
