| Summary: | The content of gibberellic acid (GA<sub>3</sub>) in male sex organs of <i>Chara tomentosa</i> L. was estimated using capillary electrophoresis. Young antheridia contained 0.25 &#956;g GA<sub>3</sub> while mature ones 0.48 &#956;g per antheridium. Although there are significant differences in GA<sub>3</sub> content in antheridia between <i>C. vulgaris</i> and <i>C. tomentosa</i>, 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 GA<sub>3</sub>-dependent development of <i>Characeae</i> species allow an implication that the mechanisms controlling antheridia differentiation in both species can be similar |
