且与光合速率稳定阶段基本一致。因此说光合功能衰退与叶片中保护酶系的下降和MDA的积累有内在的关系。
So there are inherent relations between photosynthesis function decline and fall of the Protective Enzyme System and accumulate of MDA.
以两个粳稻品种武育粳3号和97-7作材料研究了光合功能衰退进程中叶片中可溶性蛋白质、游离氨基酸和内肽酶活力的变化。
Two japonica rices, Wuyujing 3 and 97.7 were used to study changes in contents of soluble protein, free amino acids and endopeptidase activity during photosynthetic declination.
主茎下部衰老叶片的SOD、POD活性明显降低、叶绿素含量减少、光合作用功能衰退。
SOD and POD activity descended apparently, and chlorophyll contents and photosynthesis declined in senescent leaves of lower stem.
