摘要: 能量是采后果蔬维持正常生理代谢活动的基础。近年来的研究表明,能量亏缺是导致采后果蔬衰老的重要因素。本文从采后果蔬的呼吸代谢、活性氧和细胞膜完整性与能量状态的关系等方面阐述能量状态在果蔬采后衰老中的作用,并对采后果蔬能量状态的调控措施以及调控机制等方面的研究进展进行综述。此外,从能量合成、转运、耗散和感知相关基因在转录和蛋白水平的表达与调控,采后果蔬衰老的起始因子,能量亏缺的应激反应等方面进行展望,旨在为从能量角度探究采后果蔬衰老的机制和研发果蔬采后保鲜新技术提供参考。

Abstract: Energy is the basis for maintaining the normal physiological metabolism of postharvest fruits and vegetables. Recent studies have shown that energy deficiency is a vital factor inducing the senescence of harvested fruits and vegetables. This paper discusses the role of energy status in the senescence of harvested fruits and vegetables from the perspectives of its relationship with respiratory metabolism, reactive oxygen species and cell membrane integrity. Moreover, recent advances in the regulatory measures and mechanisms of energy status in harvested fruits and vegetables are reviewed. The expression characteristics and regulation of genes related to energy synthesis, transport, dissipation and perception, the initiating factors of the senescence process in harvested fruits and vegetables, and stress response to energy deficiency are also covered. This review aims to provide a basis for exploring the mechanism of senescence of postharvest fruits and vegetables from the perspective of energy and for the development of new preservation technologies.

Key words: fruits and vegetables, senescence, energy status, energy deficiency, energy regulation
