The protochlorophyllide content of dark-grown bean leaves was determined at various ages. It was detectable the second day after germination and reached a maximum on about the tenth day.The resynthesis of protochlorophyllide following a single irradiation and the rate of the 685 to 673 mmu shift of the newly formed chlorophyll was examined. Leaves up to 5-days old show no lag phase in protochlorophyllide resynthesis. By the sixth day, a lag phase is evident which increases with age. The rate of the 685 to 673 mmu shift is similarly age dependent.
测定了不同生长阶段黑暗中生长的菜豆叶片中原叶绿素酸酯的含量。在萌发后的第二天即可检测到，在大约第十天达到最大值。研究了单次照射后原叶绿素酸酯的重新合成以及新形成叶绿素从685至673毫微米的位移速率。5日龄及以下的叶片在原叶绿素酸酯重新合成过程中没有滞后阶段。到第六天，明显出现滞后阶段，且随着叶片年龄的增加而延长。685至673毫微米的位移速率同样与叶片年龄有关。
