Abstract:

This paper summarizes the evaluation status of chilling tolerance of cucurbitaceous vegetables from seed vigor，seedling morphological and physiological and biochemical indicators. Furthermore，the physiological basis and the identification of functional genes of chilling tolerance of cucurbitaceous vegetables are discussed. Finally，effective ways to improve the low temperature tolerance of cucurbitaceous vegetables by breeding，agronomic measures and exogenous substance application are elaborated. The objective of this review is to provide reference for further constructing scientific and rapid evaluation system of chilling tolerance and solving the problem of chilling damage in cucurbitaceous vegetables production.

Key words: cucurbitaceous vegetables, low temperature, evaluation system, cold resistant mechanism, regulation measure
