英文摘要	Selecting drought-tolerant alfalfa cultivars is conducive to improve the forage yield in arid and semi-arid areas. In this study, drought resistance of five alfalfa (Medicago sativa L.) cultivars at the seedling stage was analyzed by using agronomic and physiological indicators. After withholding water for 6 days and then re-watering for 4 days, shoot dry weights of Longdong and Daye were significantly higher than that of the other cultivars. Under drought stress, Daye had healthier plasma membrane with the minimum leaf membrane permeability, while the leaf osmotic potential of Longdong and Gannong No. 3 were significantly lower than that of the other three cultivars. Moreover, Longdong showed the highest leaf relative water content. According to the combination of above indicators, the relative drought resistance of the five cultivars decreased in order: Longdong, Daye, Gannong No. 3, Sandili, and Rambler. This study suggested that Longdong and Daye might be more suitable for planting in arid and semi-arid regions.
