| 摘 要： | 实验研究了不同熟期的大久保桃果肉超微结构变化、果实成熟过程中的乙烯释放规律、Ｌｏｘ酶活性、ＰＧ酶活性变化规律以及相关代谢。结果表明:(１)桃果实超微结构的成熟衰老变化先于乙烯高峰的出现和ＰＧ酶活性的快速上升,但乙烯、ＰＧ仍然是影响超微结构衰老变化的重要因素。(２)Ｌｏｘ可能是引起超微结构前期变化的因素。

| Abstract: | The changes of flesh ultrastructure and its relationship with endo-ethylene, Lox, PG during the ripening process ofOkubao peach variety were studied. Results showed①The changes of nesh ultrastructure were staried earlier than ethylenepeak and the promotion of PC activity,but ethylene and PG were still the important elements caused the changes;②It mightbe possible that the earlier ultrastructural changes was caused by Lox. |
