The Relationships between Fertility and Contents of Gibberellic Acid, Sugars and Dry Mass in Apical Parts of Chara Vulgaris Thalli
- 1 Department of Cytophysiology, University of £ód¼, £od¼, Poland
The contents of endogenous gibberellic acid (GA3), sugars, and dry mass in apical parts of fertile and sterile thalli of Chara vulgaris were estimated. The GA3 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 GA3 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 GA3, 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.
