PRESERVATION OF AZOTOBACTER ON CUCUMIS SATIVUS L. SEEDS UNDER DIFFERENT TEMPERATURES
Journal Title: Сільськогосподарська мікробіологія - Year 2018, Vol 27, Issue
Abstract
The results of studies on the effect of temperature on the preservation of Azotobacter chroococcum M-70 and Azotobacter vinelandii M-X cells on the seeds of Cucumis sativus L. are presented. In three months, the number of bacterial cells on the seeds, which were kept at + 4°C, was significantly higher than the parameters of the storage of seeds at +28° С. Azotobacter cysts were preserved better than vegetative cells. To increase the viability of bacterial cells on the seeds, it is proposed to use a complex of chemical substances that provides better survival of both vegetative cells and Azotobacter cysts. The results of the studies can be used to develop new ways to improve the viability of useful soil microorganisms on seeds of agricultural crops.
