摘要
黑麦草属(Lolium)植物是一种根系发达、分蘖多、适口性好、营养价值高的牧草,深受牛、羊等反刍动物的喜爱.近年来,黑麦草因受环境胁迫的影响,其生长发育受阻,产草量显著降低,因此,探究黑麦草属植物对环境胁迫的响应和提升途径具有重要意义.文章综述了黑麦草属植物的耐旱、耐盐碱、耐高温、耐低温和耐重金属5个抗逆性方面的研究进展,并对黑麦草属植物今后的研究方向进行了展望,以期为加快我国黑麦草属植物抗逆育种进程提供参考.
Abstract
Lolium plant is a kind of pasture grass with well-developed roots,multiple tillers,good palatability,and high nutritional value,which are highly favored by ruminant mammals such as cows and sheep.In recent years,the growth and development of Lolium have been hindered by environmental stress,resulting in a significant decrease in grass yield.Therefore,exploring the response of Lolium plants to environmental stress and enhancement pathways are of great significance.This article reviewed the research progress on drought resistance,salt alkali resistance,high temperature resistance,low temperature resistance,and heavy metal resistance of Lolium plants,and looks forward to the future research directions of Lolium plants,in order to provide reference for accelerating the process of stress resistance breeding of Lolium plants in China.
