摘要
紫花苜蓿(Medicago sativa)是世界上最重要的豆科牧草之一,但盐渍化土地严重制约着其种植范围。培育耐盐新品种是降低盐渍化土地对紫花苜蓿生长和产量影响的有效途径。笔者综述了紫花苜蓿耐盐生理、盐诱导相关基因以及耐盐性育种方面的主要进展,并对紫花苜蓿耐盐性研究的前景进行了讨论。
Alfalfa(Medicago sativa) is one of important legume forages worldwide.However,the growth range of alfalfa is limited due to its sensitivity to soil salinity,and breeding salt-tolerant alfalfa cultivars is one approach to reducing the deleterious effects of soil salinity on alfalfa production.This article has reviewed the salt-tolerance physiology,genes induced by salt stress and salt-tolerant breeding of alfalfa.The further researches on salt-tolerance alfalfa have also been discussed.
