采后黄瓜冷害及耐冷性调控研究进展

Research advances in chilling injury and the regulation of chilling tolerance of postharvest cucumber fruit

黄瓜是冷敏型果菜类蔬菜,采后黄瓜在低温贮藏期间很容易发生冷害,降低采后品质,缩短贮藏寿命,造成较大的采后损失。因此,探明采后黄瓜冷害发生机制,并有针对性地提出冷害防控措施,是当下果蔬采后保鲜研究领域中迫切需要解决的科技问题。近年来,在采后黄瓜冷害防控及耐冷性调控研究方面取得了一系列进展。本文重点从采后黄瓜冷害症状、冷害发生过程中的生理生化变化和防控技术等角度,总结了采后黄瓜冷害及耐冷性调控研究方面的进展,可以为采后黄瓜的低温贮藏和冷害防控研究提供借鉴和参考。

Cucumber is a kind of chilling-sensitive fruit vegetable.Harvested cucumber is subjected to chilling injury under cold storage conditions,which will reduce the postharvest quality and shorten the storage life,and cause great postharvest losses.Therefore,the urgent scientific-technical issue to be solved in the field of postharvest preservation of fruits and vegetables is to ascertain the mechanisms of chilling injury in harvested cucumber and propose purposeful technical measures for the prevention of chilling injury.In recent years,a series of important progresses about prevention technologies of chilling injury and the regulation of chilling tolerance in harvested cucumber have been made.This article comprehensively summarized research advances on chilling injury and chilling tolerance of harvested cucumber fruit,from the perspectives of chilling injury symptoms,physiological and biochemical changes during the occurrence of chilling injury,and prevention techniques.This article can provide references for the research of cold storage technology and prevention technologies of chilling injury in harvested cucumber.
