摘要： 非生物胁迫(低温、高温、干旱、水涝、盐害等)是影响牧草生长和发育的重要因素,因而探究牧草抗逆性响应特征、指标、评价方法和提升途径,对于提升和稳定牧草生产有重大意义。本文通过文献资料调研和计量分析方法,综述了牧草对温度、水分和盐分等非生物胁迫作用的响应,概述了牧草的形态结构、生理生化和生产性能抗逆性指标,总结了6类牧草综合评价方法的原理和优缺点,综述了4种牧草抗逆性提升途径,并对今后在非生物胁迫下牧草抗逆性方向上需开展的3个方面研究工作进行展望,以期为选取牧草抗逆性指标和评价方法,提升牧草质量和产量提供参考依据。

Abstract: Abiotic stresses,especially low temperature,high temperature,drought,waterlogging,salt damage,etc.,are important factors affecting the growth and development of forages. Therefore,it is of great significance to explore the characteristics,indicators,evaluation methods and measures for improving forage stress resistance and stabilizing forage production. In this paper,the responses of forages to abiotic stresses such as temperature,water and salt were investigated through literature review and quantitative analysis. We reviewed the morphological structure,physiological and biochemical indicators and production performance resistance indices of forages,summarized the principles,advantages and disadvantages of six types of comprehensive evaluation methods for the abiotic stress resistance of forage,proposed four measures to improve the stress resistance of forages,and pointed out three aspects of future research in the field of abiotic stress resistance of forages. This review is expected to provide insight into selecting forage stress resistance indicators and evaluation methods to improve forage quality and yield.

Key words: Stress resistance indicators, Abiotic stress, Evaluation method, Forages
