Changes in RuDP Carboxylase Activity of Rice Leaf Blade at Various Growing Stages

[摘要] Ribulose-1, 5-diphosphate (RuDP) carboxylase, catalase and acid phosphatase activitics, and chlorophyll and soluble protein contents expressed in term of unit leaf area were investigated at various stages of leaf growth in pots. The following results were obtained : (1) When the leaf blade was divided into three equal parts, RuDP carboxylase activity of each part of young leaf blade immediately after it had fully expanded showed the ranking order: middle≥top
