influence of ground cover management on diversity and density of phytoseiid mites (acari: phytoseiidae) in guadeloupean citrus orchards.the abundance and diversity of phytoseiid mites in the vegetal ground cover of a citrus orchard were surveyed by monthly samplings from october 2008 to july 2009. six different vegetal cover management methods were studied: herbicide application without mowing (gly), mowing without herbicide application (pv), mowing with herbicide application (av), late mowing without herbicide application (lmv), cover crop (neonotonia wightii, fabaceae) without herbicide application (pneo) and cover crop with h ...201020480212
bradyrhizobium tropiciagri sp. nov. and bradyrhizobium embrapense sp. nov., nitrogen-fixing symbionts of tropical forage legumes.biological nitrogen fixation is a key process for agricultural production and environmental sustainability, but there are comparatively few studies of symbionts of tropical pasture legumes, as well as few described species of the genus bradyrhizobium, although it is the predominant rhizobial genus in the tropics. a detailed polyphasic study was conducted with two strains of the genus bradyrhizobium used in commercial inoculants for tropical pastures in brazil, cnpso 1112t, isolated from perennia ...201526362866
chemical composition of certain tribal pulses in south india.raw seeds of tribal pulses atylosia scarabaeoides, canavalia gladiata, lablab purpureus var. lignosus, neonotonia wightii var. coimbatorensis, rhynchosia filipes, vigna trilobata and vigna unguiculata subsp. unguiculata were investigated for their proximate composition, minerals, vitamins (niacin and ascorbic acid) and certain anti-nutritional substances. the seeds of l. purpureus var. lignosus and v. trilobata had a higher content of crude protein than the commonly consumed indian pulses. the s ...200312775370
nitric oxide and nitrous oxide production by soybean and winged bean during the in vivo nitrate reductase assay.this study was conducted to determine by gas chromatography (gc) and mass spectrometry (ms) the identity and the quantity of volatile n products produced during the helium-purged in vivo nr assay of soybean (glycine max [l.] merr. cv williams) and winged bean (psophocarpus tetragonolobus [l.] dc. cv lunita) leaflets. gaseous material for identification and quantitation was collected by cryogenic trapping of volatile compounds carried in the he-purge gas stream. as opposed to an earlier report, a ...198616665099
root-knot nematode management in dryland taro with tropical cover crops.twenty-two cover crops were evaluated for their ability to reduce damage by root-knot nematode, meloidogyne javanica, to taro, colocastia esculenta, in a tropical cropping system. cover crops were grown and incorporated into the soil before taro was planted. barley, greenpanic, glycine, marigold, sesame, sunn hemp, and sorghum x sudangrass dekalb st6e were poor or nonhosts to the nematode as measured by low population changes of nematodes in soil between cover crop planting and taro planting. al ...199719274275
5s rrna genes in tribe phaseoleae: array size, number, and dynamics.the organization of 5s rrna genes in plants belonging to tribe phaseoleae was investigated by clamped homogeneous electric field gel electrophoresis and southern blot hybridization. representatives of subtribe glycininae included the diploid species neonotonia wightii and teramnus labialis, as well as three soybean accessions: an elite glycine max (l.) merr. cultivar (bsr101), an unadapted g. max introduction (pi 437.654), and a wild glycine soja (pi 468.916). a cultivar of phaseolus vulgaris (k ...199618469906
