数据报告的变化，总过氧化物酶活性和过氧化物酶同工酶的模式发生在Shamamelo橙子叶的剥离区和相邻组织之前和期间的叶片分离中存在的应用IAA和乙烯。有一个密切的相关性之间的过氧化物酶活性的增加和未处理的控制，并在叶片中的延迟（IAA）和加速（乙烯）生长调节剂施加的时间过程中的delisission;过氧化物酶活性在delisission区比在相邻的组织在所有的治疗。2种生长调节剂对同工酶水平的影响方向相反，但对它们没有定性影响。
Data are reported on changes in total peroxidase activity and peroxidase isoenzyme patterns occurring in the abscission zone of Shamouti orange leaves and in adjacent tissues before and during leaf separation in the presence of applied IAA and ethylene. There was a close correlation between increase in peroxidase activity and the time course of abscission in untreated controls, and also in leaves where the retarding (IAA) and accelerating (ethylene) growth regulators were applied; peroxidase activity was higher in the abscission zone than in adjacent tissues in all treatments. The 2 growth regulators affected isoenzyme levels in opposite directions but had no qualitative effects on them.
