紫花苜蓿Medicago sativa因其营养丰富被广泛栽培,已成为草食家畜和奶牛养殖业的重要饲草,更是一种重要的生态改良草,在我国畜牧业发展和生态保护中起着不可比拟的作用.高温是影响紫花苜蓿生长的重要限制因子,研究发现高温胁迫致使植物发生一系列生理、生化及形态上的响应.在河南省,由于夏季高温的胁迫,致使紫花苜蓿夏眠,甚至死亡,严重影响其品质和产量.结合植物自身的调节机制,从植物形态及抗氧化系统综合阐述了高温条件下紫花苜蓿的抗热性鉴定方法和评价指标,旨为其抗热性鉴定和选育工作提供一定的科学参考.

High temperature is one of the limiting factors in alfalfa production, which induces a series of responses in physiology and morphology. Alfalfa in Henan Province usually aestivate or died because of the high temperature stress, which affects quality and yield of the forage greatly. The progress of identification methods and evaluation indexes for heat resistance of alfalfa were summarized in this paper.
