摘要: Summary Chara braunii is distributed worldwide and the most common charalean species in Japan. This monoecious produces numerous sets of sex organs, each which consists one antheridium oogonium, under laboratory culture conditions. In this study, we report that light intensity strongly affected vegetative phase sexual reproductive species. Under high-light conditions (70.0 μmol photons m−2 s−1), thalli grew but did not form organs. a low-light (10.0 μmol algal bodies formed many addition, antheridia without corresponding oogonia (lone antheridia) were observed The absence oogonium primordia adjacent to lone was confirmed by several microscopic approaches. addition liquid fertilizer increased total number organs growth; however, decreased with increasing concentrations. Exogenously applied gibberellin affect antheridia. These results suggest regulatory mechanisms for appropriate allocation resources exist alga, similar those reported some land plants.
