1. Pollen viability and stigma receptivity in Swainsona formosa (G.Don) J.Thompson (Fabaceae), an ornamental legume native to Australia
Abstract Pollen viability and stigma receptivity are prerequisites for successful cross-pollination and seed set in Swainsona formosa. In this study, the pollen viabilities and stigma receptivities was assayed by in vitro pollen germination and simple hand-pollination method on glasshouse-grown plants, respectively. The viability of pollen grains was tested

2. Germination of Crotalaria and Lupinus (Fabaceae) seeds submitted to different pre-germination treatments and their effect on enzymatic activity during early germination
Resumo A maioria das sementes de leguminosas nativas e selvagens têm um tegumento rígido e impermeável, o que causa dormência física e impede a germinação, mesmo se as condições ambientais forem favoráveis. O estudo avaliou o efeito de tratamentos de escarificação sobre a germinação e a atividade enzimática de sementes de Crotalaria longirost

3. Isolation, Characterization and Symbiotic Efficiency of Nitrogen-Fixing and Heavy Metal-Tolerant Bacteria from a Coalmine Wasteland
ABSTRACT: Areas affected by coal mining can be recovered by revegetation with leguminous plants associated with nitrogen-fixing bacteria. This study addressed the isolation and characterization of native nitrogen-fixing bacteria from coalmine wasteland under different vegetation restoration approaches using Macroptilium atropurpureum (DC) Urb and Vicia sativ

4. Physicochemical, structural and thermal properties of oxidized, acetylated and dual-modified common bean (Phaseolus vulgaris L.) starch
Abstract Common beans are rich in protein and complex carbohydrates that are valuable for the human diet. Starch is the most abundant individual component; however, in its native form it has limited applications and modifications are necessary to overcome technological restrictions. The aim of this study was to evaluate the influence of oxidation, acetylatio

5. Whisker-mediated transformation of peanut with chitinase gene enhances resistance to leaf spot disease
Abstract Peanut (Arachis hypogaea) is an important legume and oilseed crop, native to South America and grown in all tropical and temperate regions of the world. A simplified and rapid direct gene delivery system in peanut was developed by vortexing silicon carbide whiskers with callus and with plasmid harboring chitinase and hygromcin genes. The effects of

6. Symbiotic potential and survival of native rhizobia kept on different carriers
Native rhizobia are ideal for use as commercial legume inoculants. The characteristics of the carrier used to store the inoculants are important for the survival and symbiotic potential of the rhizobia. The objective of this study was to investigate the effects of peat (PEAT), perlite sugarcane bagasse (PSB), carboxymethyl cellulose plus starch (CMCS), an

7. Chemical composition and antioxidant activity of jatobá-do-cerrado (Hymenaea stigonocarpa Mart.) flour
The Brazilian Savannah, known as "Cerrado," has an extensive biodiversity, but it is under explored. Among the native vegetables is the jatobá-do-cerrado (Hymenaea stigonocarpa Mart.), a legume with great potential for exploration for its content of dietary fiber. Legumes are an important source of nutrient compounds, such as phenolic compounds and vitamins

8. Symbiotic nitrogen-fixing bacterial populations trapped from soils under agroforestry systems in the Western Amazon
Cowpea (Vigna unguiculata) is an important grain-producing legume that can forego nitrogen fertilization by establishing an efficient symbiosis with nitrogen-fixing bacteria. Although inoculating strains have already been selected for this species, little is known about the genotypic and symbiotic diversity of native rhizobia. Recently, Bradyrhizobium has be

9. Forage yield and nitrogen nutrition dynamics of warm-season native forage genotypes under two shading levels and in full sunlight
The successful achievement of a highly productive understorey pasture in silvopastoral systems depends on the use of well-adapted forage genotypes, showing good agronomic performance and persistence under shading and grazing. In this study, the herbage dry matter yield (DMY) and nitrogen nutrition dynamics were determined in three native warm-season grasses

10. Tolerance of Anadenanthera peregrina to Eucalyptus camaldulensis and Eucalyptus grandis essential oil as condition for mixed plantation
With the purpose of selecting the species of woody Caatinga for mixed plantations with Eucalyptus spp., the allelophatic effects of E. camaldulensis and E. grandis essential oil were studied on the growth activities of Anadenanthera peregrina. The plants were closed in glass chambers in the presence of volatile oil of E. camaldulensis or E. grandis at the co

11. Microsatellite diversity and chromosome number in natural populations of Trifolium riograndense Burkart
Twenty eight natural populations of Trifolium riograndense Burkart, an important forage legume from native pastures of the state of Rio Grande do Sul, Brazil, were evaluated for genetic diversity with eight Simple Sequences Repeats (SSR) markers. Chromosome numbers were also determined. The eight markers were polymorphic, with 35 alleles and an average of 4.

12. Rizobactérias promovem o crescimento de feijoeiro-comum e de milho por diferentes processos / Rhizobacteria promote growth of common bean and maize by different processes
Plant Growth Promoting Rhizobacteria (PGPR) promote the growth of legumes and non-legume plants enhancing their nutrition, mainly of nitrogen and phosphorus. For this purpose, these bacteria make use of mechanisms such as solubilization of insoluble inorganic phosphate, plant growth hormone production and biological fixation of nitrogen in the rhizosphere, i
