Agriciltural microbiology| Резюме: | It is carried out a screening of diazotrophs, allocated from rhizosphere and rhizoplane of wheat plants of 13 sorts. It is shown, that strain Azospirillum sp. 77, allocated from rhizoplane of a spring wheat of sort Varyag, was characterized by the greatest nitrogenase activity. Inoculation of wheat seeds by specified strain promoted the increase of its germination on 22,3 % and dry weight of sprouts increase on 18,2 % in comparison with the control, that testifies the ability of Azospirillum sp. 77 to produce biologically active substances. The researched strain causes deformations of root fuzz that confirms the ability of Azospirillum sp. 77 to cause reaction on inoculation of wheat plants sorts Varyag. According to preliminary screening it is selected the strain, which capable to form effective associations with wheat plants. |
