Abstract: The population dynamics of associative nitrogen-fixers Azospirillum lipoferum 137, Arthrobacter mysorens 7, Flavobacterium sp. L30 and phosphate-solubilizing strain Agrobacterium radiobacter 10 in soil and the rhizoplane of inoculated plants was studied in pot and field experiments. All of the present strains were able to actively colonize the rhizoplane of barley, wheat, oat, tomatoes, rape, and alfalfa. For the most part the population size and dynamics of introduced bacteria depended only slightly on the plant genotype and soil conditions. The overall pictures of survival of the strains in soil and on plant roots were similar. The reliable effect of inoculation on plants was observed only in individual cases. No correlation was established between survival of introduced bacteria and their effect on plant development. It was concluded that the influence of plants on survival of bacteria was not specific. In contrast, the plant response to inoculation was conditioned to a greater extent by the plant genotype. 相似文献

In laboratory experiments, the rhizobacteria Azospirillum lipoferum 137, Arthrobacter mysorens 7, Agrobacterium radiobacter 10, and Flavobacterium sp. L30 were found to have a relatively high resistance to the toxic heavy metals lead and cadmium (except that strain L30 was found to be sensitive to Cd). When introduced by means of seed bacterization, the heavy metal-resistant strains actively colonized the rhizosphere of barley plants cultivated in uncontaminated and contaminated soils. In both pot and field experiments, seed bacterization improved the growth of barley plants and the uptake of nutrient elements from soil contaminated with Pb and Cd. The bacterization also prevented the accumulation of Pb and Cd in barley plants, thereby mitigating the toxic effect of these heavy metals on the plants. 相似文献
