一、如何判断光合作用是否进行及光合速率大小光合作用是否进行及光合速率大小,可根据以下几个指标来确定。1.以生成物淀粉作为光合作用的指标。原理为淀粉与碘液或碘蒸气变蓝色。当用淀粉的生成作为反应指标时,必须先对实验叶片进行饥饿处理,再作相关实验。在对实验后的叶片处 First, how to determine whether photosynthesis is carried out and whether the photosynthetic rate and size of photosynthesis are carried out and the size of photosynthetic rate can be determined according to the following indicators. 1. Produce starch as an indicator of photosynthesis. The principle is that starch and iodine or iodine vapor turn blue. When the production of starch is used as a reaction indicator, the experimental leaves must be starved and then subjected to relevant experiments. At the blade after the experiment
