摘 要: 通过在温室内控温和控湿的盆栽试验,对来自国内外的23种紫花苜蓿品种进行抗旱性胁迫比较试验,旨在为干旱区紫花苜蓿的选种培育提供参考依据。通过试验将23种紫花苜蓿品种分为3个抗旱等级,其中,‘爱来’、‘抗旱6号’、‘陇中苜蓿’、‘察南苜蓿’、‘矩-3苜蓿’、‘安西苜蓿’和‘定西苜蓿’属于抗旱性较强品种,而国外品种抗旱性中等。因此,在品种引进时可因地制宜进行选择。

Abstract: The experiment was carried out in greenhouse where the temperature and humidity were controlled. 23 alfalfa varieties were compared under drought stress to provide reference for the selection and breeding of alfalfa in drought area. The result showed that 23 alfalfa varieties were divided into three ranks of drought resistance, thereinto, ‘Ailai’, ‘kanghan NO.6’, ‘Longzhong’, ‘Chanan’, ‘Ju-3’, ‘Anxi’ and ‘Dingxi alfalfa’ had strong resistance to drought stress, and most of foreign alfalfa had the middle resistance to drought stress, so the introduction of a new variety should be acted according to circumstances.
