The shape of chloroplast didn't change after seedling was treated by GA〓, but the number of lamllasomes increased, and starch grain enhanced. These changes were accord to that of the rate of photosynthesis. Mitochondria varied greatly, the structure of mitochondria could see vaguely and carinace almost deliquesce after 4days. Enrolucrum emerged until the seventh day after treatment and endomembrance of mitochondria recovered gradually, cristae could be seen. On the other hand, the endomembrance of mitochondria in CK (normal non-bolting) was obvious and the quantity of cristae in the mitochondria was much more than the GA〓 treatment. This showed that respiration might decrease after GA〓 treatment while reduced the depletion of photosynthesis products and enhanced bolting.

GA〓处理后抽苔过程中叶绿体形状未发生变化，但类囊体增多，淀粉粒增多，这种变化与光合速率的变化吻合；线粒体变化较大，处理后4天线粒体结构较模糊，嵴不清晰，7天时外膜形成，内膜也逐渐恢复，能见到嵴，而对照线粒体内膜结构明显，嵴清晰数量也多，说明GA〓处理后，呼吸作用降低，减少光和产物的消耗；细胞膜无破损，较光滑完整，说明对细胞膜没有伤害。
