紫花苜蓿(Medicago sativa L.)是我国最重要的豆科牧草之一,是世界分布最广的豆科牧草,也是我国种植面积最大的人工牧草,其营养价值丰富,生物量大、再生性强,是改良土壤的绿肥植物,被称为“牧草之王”.苜蓿在干旱胁迫下的适应能力较强,能通过自身的生理代谢、结构发育和形态建造等方面适应干旱的环境条件.有关苜蓿的旱性研究一直以来都是牧草学研究的热点之一,研究领域也逐渐从形态水平发展到生理、生化及分子生物学等更深入的领域,并取得了很多有价值的研究成果.
Research Progress on Alfalfa (Medicago sativa L.) Adaptability under Drought Stress
Alfalfa (Medicago sativa L.) is one of the most important leguminous forage in China,and distributed most widely in the world.Because of Its high nutritional value,large biomass and strong reproducibility and improved soil green manure plants,it is a kind of green manure plant capable of improving soil and known as "the king of forage".Alfalfa has strong adaptability under drought stress,and could adapt drought conditions through its physiological metabolism,structure development and morphology construction.Drought resistance in alfalfa is always a hot research subject of forage,and the research has been gradually developed from the morphological level to more-deeply physiological,biochemical and molecular biology fields,and has made many valuable research achievements.
