[Morpho-functional changes of spring wheat plants under interrelation with diasotrophs of Azospirillas].

The morphological and functional changes of photosynthetic apparatus of spring wheat at inoculation by active strains of Aospirillium genus diazotrophs were studied. Inoculation resulted in an increase of mesophyll cell size of 3 spring wheat leaves and chloroplasts in them. The largest number of grains and volume of photomembranes were presented in the chloroplasts of plants inoculated by A. brasilense 77, which coincided with an increase in chlorophyll b content. In the mesophyll cells of plants inoculated by A. brasilense 102 a greater number of chloroplasts, mitochondria and peroxysomes was found as compared to other options. The spring wheat plants inoculated by the strains contained a significant amount of carotenoids.
