中文摘要：

果蔬成熟度是影响其抗冷性的重要因素，不同成熟度的果蔬由于细胞膜脂肪酸组分、细胞内含物（可溶性固形物、糖、钙、脯氨酸）含量、各类相关代谢活动（呼吸代谢、乙烯代谢、活性氧代谢、膜脂代谢）等方面存在差异而表现出不同的抗冷性。在前人相关研究的基础上，本文对果蔬的采收成熟度与抗冷性的关系及其作用机理进行综述。旨在为确定果蔬更适宜低温贮藏的采收成熟度以及减轻果蔬贮藏冷害提供理论依据。

英文摘要：

Maturity is an important factor that affects the chilling resistance of fruit and vegetable.Fruits and vegetables with different maturity show different cold resistance due to the differences in the factors such as membrane fatty acid composition,content of cell inclusions （soluble solid,sugar,calcium,proline）,and some kinds of relevant metabolic activity （respiratory metabolism,ethylene metabolism,reactive oxygen metabo-lism,membrane lipid metabolism ）.On the basic of previous correlational studies,the relationship between maturity and chilling resistance of fruit and vegetable and its acting mechanism are reviewed in this paper.The purpose is to find the appropriate maturity of fruit and vegetable for low temperature storage and to provide the-oretical foundation for alleviating the chilling injury of them.
