Gibberellic acid at 10(-4) MXXX was optimal for enhancement of growth, O2 evolution, photosystem II and I and the activity of glycollate dehydrogenase of Anacystis nidulans. A stimulatory effect was observed on photosystem II. Other concentrations of gibberellic acid were inhibitory to O2 evolution and photosystem I. Syntheses of phycocyanin, phycoerythrin and β-carotene were significantly enhanced after 48 h incubation with gibberellic acid at 10(-3) MXXX but the chlorophyll content began to increase 3 h after adding 10(-4) MXXX gibberellic acid.
10(-4) MXXX 的赤霉素最有利于增强鱼腥藻的生长、O2 释放、光系统 II 和 I 以及乙醛酸脱氢酶的活性。赤霉素对光系统 II 有刺激作用。其他浓度的赤霉素对 O2 释放和光系统 I 有抑制作用。用 10(-3) MXXX 的赤霉素处理 48 小时后，藻蓝蛋白、藻红蛋白和 β-胡萝卜素的合成显著增强，但在添加 10(-4) MXXX 赤霉素 3 小时后，叶绿素含量开始增加。
