Abstract

The content of gibberellic acid (GA₃) in male sex organs of Chara tomentosa L. was estimated using capillary electrophoresis. Young antheridia contained 0.25 μg GA₃ while mature ones 0.48 μg per antheridium. Although there are significant differences in GA₃ content in antheridia between C. vulgaris and C. tomentosa, these values calculated per one spermatid are 2.4 and 3.3 pg, respectively. The present results compiled with the previous knowledge about regulation of GA₃-dependent development of Characeae species allow an implication that the mechanisms controlling antheridia differentiation in both species can be similar
