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。
Alfalfa (Medicago sativa L.) is one of the most important legume forages in our country, and is the most widely distributed leguminous forage in the world. It is also the largest artificial forage in China with rich nutritional value, large biomass and strong regenerative ability , Is to improve the soil of green manure plant, known as the “king of pasturage.” Medicago sativa has strong adaptability under drought stress and can adapt to drought conditions through its own physiological metabolism, structural development and morphological construction. Studies on the drought resistance of alfalfa have always been one of the hot topics in pasture research. The fields of research have gradually evolved from the morphological level to more in-depth fields such as physiology, biochemistry and molecular biology, and many valuable research results have been obtained.
