摘要/Abstract

摘要： 在夏玉米生育过程中,系统地测定了个体和单叶水平的光合速率动态过程以及对影响叶片光合速率的主要因素的分析表明:在个体水平内,每一叶片的动态表现形式基本相同。初步可分为四个连续的阶段:①Ph(净光合速率)和LA(叶面积)同步增长;②Ph、LA高值出现;③Ph缓降;④叶片衰老Ph速降。不同叶位叶片在光合速率的动态过程中所达到的

Abstract: The dynamic Changeas of the photosynthetic rates (Pn) of individual plants andindividual leaves were studied during the course of growth and development ofSummer-sown corn. The results indicated that the pattern of the course of the dynamicchamges of the Pn of every individual leaf was fundementally
