摘　　要：通过测定9个不同苜蓿Medicagosativa品种的保水力、水势、细胞膜相对透性、脯氨酸含量等生理指标,对9个不同苜蓿品种的抗旱隶属函数值进行计算,对不同苜蓿品种的综合抗旱适应性进行评价。抗旱性排序为:保丰>超级13R>路宝>牧歌>爱博>爱林>新疆大叶>巨人>全能。同时表明,抗旱性是一个综合指标,不应由单一指标决定。the study was conducted on nine alfalfa varieties with different drought resistance under semiarid conditions 4 physiological drought resistance characteristics, water retention capabilities, water potential,cell membrane stability and proline content, were measured and a comprehensive evaluation on drought resistance of different alfalfa varieties was given based on subordinate function values analysis Results indicated that the order of drought resistance from high to low was:BaoFeng>13R supreme>Lobo>AmeriGraze401+Z> Arriba >Abilene+Z>Xingjiang big leaf>Ameristand201+Z>Total+Z

关 键 词：苜蓿 抗旱性 隶属函数值 保水力 细胞膜相对透性 脯氨酸含量
