Abstract
Light-induced fluorescence quenching of atebrin in isolated pea chloroplasts was studied. The observed quenching effect was shown to be influenced by DCMU, ADP+P and cofactors of photosynthetic electron transport. In the presence of ADP+P the amplitude of the quenching in control plants was not changed, whereas in the pea mutant blocked at PS2 it was considerably decreased. However the dark decay rate of the quenching effect in both cases increased 2-3 folds.
摘要
研究了光诱导的阿的平在离体豌豆叶绿体中的荧光猝灭。观察到的猝灭效应受二氯苯基二甲基脲（DCMU）、ADP + P以及光合电子传递的辅助因子影响。在有ADP + P存在时，对照植物中猝灭的幅度没有变化，而在PS2处受阻的豌豆突变体中，猝灭幅度显著降低。然而，在这两种情况下，猝灭效应的暗衰减速率都增加了2至3倍。
