Abstract
With increasing of generations, chlorophyll content in the top three leaves decreased gradually, andthe change in the 3rd leaf was more obvious; ATPase activity, ABA content and net photosynthetic rate de-creased gradually in flag leaf of Oryza sativa cv. ‘Liaojing 326’ but didn’t change in cv. ‘Aoyu 316’. Whilephotosynthetic rate of plant population decreased significantly and difference was evidence between n and n+4.
