The relationship between resistance of cowpea (Vigna unguiculata) accessions to low temperatures and diseases in Siberia
... samples and their susceptibility to pathogenic micromycetes. Ten Vigna unguiculata samples were used. Pollen viability in vitro was assessed in a 20 % PEG 6000 solution at 25 °C for 3 hours (control) and at 6 °C for 24 hours (cold tolerance assessment). Seed germination under low temperatures was evaluated by germinating seeds on filter paper at 10, 12, and 25 °C (control), as well as in soil at a constant 25 °C and under a regime of 10 °C for 10 days followed by 25 °C. Root system adaptability to ...
Study of the effectiveness of using bacteria Bradyrhizobium japonicum and Bradyrhizobium elkanii as a microbiological inoculant for soy seeds
... demand. Nodulating bacteria of the genus Bradyrhizobium are considered promising candidates for such inoculants. The aim of this study was to isolate and investigate Bradyrhizobium japonicum and Bradyrhizobium elkanii and to develop a microbiological seed inoculant based on these bacteria. Optimal cultivation conditions were determined to achieve the maximum titer of viable bacterial cells. A microbiological inoculant composition was developed, and a prototype was created. Field trials of the experimental ...
