正己醇处理对草莓果实采后生理和品质的影响

以"达塞莱克特"草莓果实为实验材料,研究了采后正己醇处理对草莓果实品质和生理的影响,以探索保持草莓果实采后品质,延长其贮藏期的措施;并为非呼吸跃变型果实的采后贮藏保鲜提供新的思路.通过0.05;、0.1;正己醇处理对草莓果实失重率、腐烂指数、VC含量、过氧化物酶(POD)活性、脂氧合酶(LOX)活性和丙二醛(MDA)含量的影响研究,结果表明,经正己醇处理后的草莓果实降低了腐烂率和失重率,维持较高水平的VC含量和过氧化物酶(POD)活性,并降低了脂氧合酶(LOX)活性和丙二醛(MDA)含量,从而延缓果实的衰老,有利于保持草莓果实采后品质.

Effect of 1 -Hexanol Treatment on Postharvest Physiology and Quality of Strawberry Fruit

To find new ways in maintaining the postharvest quality and extending the storage life of strawberry fruits and provide new ideas in the postharvest storage of non - climacteric fruits,'Darselect' strawberry(Fragaria ananassa Duch.) was used to investigate the effects of 1-hexanol treatment on postharvest physiology and quality of fruits.After treatment with 0.05%and 0.1%1 - hexanol,the weight loss rate,decay index,vitamin C content, POD activity,LOX activity and MDA content of fruits were studied during storage.The results showed that 1 - hexanol treatment lowered the weight loss rate and decay index,were higher levels vitamin C content and POD activity were,but LOX activity and MDA content were decreased,which is beneficial to delay the senescence and keep the postharvest quality of strawberry fruits.
