Bradyrhizobium japonicum Survival in and Soybean Inoculation with Fluid Gels.
The utilization of gels, which are used for fluid drilling of seeds, as carriers of Bradyrhizobium japonicum for soybean (Glycine max (L.) Merr.) inoculation was studied. Gels of various chemical composition (magnesium silicate, potassium acrylate-acrylamide, grafted starch, and hydroxyethyl cellulose) were used, although the hydroxyethyl cellulose gels were more extensively investigated. Gel i...
متن کاملChemotaxis of Bradyrhizobium japonicum to soybean exudates.
The chemotactic response of Bradyrhizobium japonicum toward soybean seed and root exudates was examined. Assays using various isoflavones and fractionated exudate indicated that isoflavones are not the principal attractants in exudates. Likewise, induction of nod genes with isoflavones or seed exudate before assay did not enhance chemotaxis. Screening of numerous compounds revealed that only di...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولStability of Bradyrhizobium japonicum Inoculants after Introduction into Soil.
Bradyrhizobium japonicum USDA 125-Sp, USDA 138, and USDA 138-Sm had been used as inoculants for soybean (Glycine max (L.) Merr.) in soils previously free of B. japonicum. At 8 to 13 years after their release, these strains were reisolated from soil samples. A total of 115 isolates were obtained through nodules, and seven colonies were obtained directly by a serological method. The stability of ...
متن کاملPhysiological Responses of Soybean - Inoculation of Bradyrhizobium japonicum with PGPR in Saline Soil Conditions
Soil salinity is one of the most severe factors limiting nodulation, yield and physiological response in soybean. The possible role of plant growth promoting rhizobacteria (PGPR) in restricting mineral nutrients and thus alleviating soil salinity stress during plant growth has not yet been established. In this study, the beneficial effects of inoculation with salt-stressed PGPR strains were inv...
