几种林果低温贮藏的冷害及其调控研究进展

冷害可造成林果采后低温贮运损失．使其食用品质下降，甚至不能食用。笔综述了林果的冷害症状、冷害机理，并重点介绍了如何防治林果低温贮藏冷害的方法，其中包括变温贮藏、化学物质处理、气调贮藏及其他方法。最后探讨了这些方法在生产中应用的可能性及存在的问题，提出了冷害修复可作为林果冷害防治进一步研究的方向。

Chilling Injury and Anti-chilling Injury Measure of Fruit During Low Temperature Storage

The characteristics of chilling injury of most fruit during cold storage are lack of juiciness and bright gloss,flesh browning and unable to soft or ripen normally and so on.There are many hypotheses about the principle of chilling injury at present,but most of them indicated that the essential cause of chilling injury is the damage of membrane construction caused by low temperature.The approaches to reduce chilling injury of fruit during low temperature storage are concluded to four aspects:(1)Changing temperature storage.This measure includes low temperature preconditioning,intermittent warming(dual temperature cycle and undulating temperature) and heat treatments.(2)Chemical substance treatments.It consists of calcium,SE,BHA,BHT,ABA and polyamines treatments etc.(3)Controlled atmosphere storage.For example,high content of CO_2 and low content of O_2 can alleviate chilling injury.(4)Other treatments such as postponing harvest,high humidity storage,packaging and so on.The possibility of applying these methods in production and the existent problems were disscussed,and advises that chilling injury restoring can be further studied as a direction of anti-chilling injury measure of fruit.
