Abstract: | In male sex organs of Chara vulgaris L., the gibberellic acid (GA3), was identified by capillary zone electrophoresis. The antheridia at cell division stage of antheridial filaments leading to formation of spermatids contain 0.09 microg GA3 per antheridium, i.e. 5.3 times more than antheridia at differentiation stage of spermatozoids (spermiogenesis). Spermiogenesis is not regulated by gibberellins. |
