Abstract

This paper presents research results on the sensitivity of buckwheat (Fagopyrum esculentum Moench.) inoculated with phosphate solubilizing microorganisms (PSM) to phosphorus deficiency using the transformation of major photosynthetic tissues membrane lipids as the indicator. The analysis of glyco- and phospholipids performed has revealed the plants’ ability to react to a deficit in phosphorus with the selective accumulation of sulfoquinovosyldiacylglycerol (SQDG) and digalactosyldiacylglycerol (DGDG) along with a decrease in phosphatidylglycerol (PG). Pre-sowing seed bacterization with PSM has balanced out the negative impact of a phosphorus deficiency on plants by stabilizing the PG content and reducing the difference in the PG/SQDG ratio.
