Influence of soil saprophyte fungus Chaetomium cochliodes on associative system "Triticum aestivum – Azospirillum brasilense"

Abstract

In laboratory and vegetative experiments the ability of soil ascomycete C. cochliodes 3250 to promote the penetration of Azospirillum nitrogen-fixing bacteria into roots’ inner tissues was shown. At the same time the endophytic association: spring wheat – Azospirillum nitrogen-fixing bacteria – soil saprophyte ascomycete C. cochliodes 3250 is forming. It allows activating the nitrogen fixation in the spring wheat roots zone and biosynthetic processes in plants, in particular: to raise glutamine synthetase activity, chlorophylls content in leaves and plants’ productivity.
