Abstract

The contents of endogenous gibberellic acid (GA_3), sugars, and dry mass in apical parts of fertile and sterile thalli of Chara vulgaris were estimated. The GA_3 concentration in the first node of fertile thallus, determined by capillary electrophoresis, was about 70.0 mg kg^−1 of fresh mass (f.m.). Pisum sativum-bioassay showed GA_3 concentration of 80.0 mg kg^−1 (f.m.) which was about 3 times higher than in the first node of sterile thallus. The higher amount of GA_3, glucose, and the lower starch content and dry mass in fertile plants than in sterile ones suggest the interdependence between fertility and contents of studied components.
