Comparative study on drought resistance of alfalfa cultivars at seedling stage between China and Australia

摘要：

In this study, seedlings of two Australian alfalfa Super10 and Prime and two Chinese alfalfa Zhaodong and Wudi (provided by SARDI) were evaluated during the imposed drought stress under greenhouse conditions to compare the physiological characteristics of drought resistance between cultivars.The objectives are (i) to evaluate physiological traits of four alfalfa cultivars that contribute to tolerance for water deficit at the seedling stage, and (ii) to understand the response of these cultivars to drought stress may further to understand the mechanisms of drought tolerance of different germplasm, that could be incorporated into breeding programs to improve drought tolerance.
