【摘要】 本文对麻醉瓜采收前后及衰老期间的呼吸强度、乙烯生成及内源生长调节物质作了测定。麻醉瓜成熟过程中 ABA 首先生成并积累,当 ABA 达到一定水平后才出现乙烯的生成。与杏果相似,麻醉瓜成熟期间果肉中 ABA 大量积累,生长促进物质迅速消失,这可能是它不耐贮藏的内在生理原因。更多还原

【Abstract】 Respiratory rate and ethylene evolution and the levels of endogenous growth regulating substances were determined before and after harvest during the period of senescence of canta- loupes.It was endogenous ABA which appeared first and accumulated during the maturation period,once it reached a certain threshold level the automatic catalysis of ethylene production was triggered.Like apricot fruits,the ABA-like substances accumulated generously in fruit flesh during maturation and the growth promoting substances disappeared rapidly.This se- ems internal physiological cause of the cantaloupes corruption.更多还原
