摘　　要：为筛选适合盐渍化土地种植的耐盐型作物,以14个紫花苜蓿(Medicago sativa)杂交组合F1代为试验材料,采用室内盆栽法,研究不同浓度盐胁迫对其幼苗的过氧化氢酶(CAT)活性、丙二醛(MDA)含量、可溶性糖(SS)含量以及可溶性蛋白(SP)含量的影响,并结合隶属函数法综合评价14个紫花苜蓿杂交组合的抗盐能力强弱。不同杂交组合对不同浓度的盐胁迫反应不一。根据紫花苜蓿杂交组合对各指标的综合评价,结果表明,耐盐性较好的杂交组合为骑士-2(2010)×MS-GN,WL319HQ×MS-GN,维多利亚×MS-GN,阿迪娜×MS-GN,甘农3号×MS-GN。In order to screen salt-tolerant crops suitable for salinized land,14alfalfa(Medicago sativa)F1hybrid combinations were tested using an indoor potting method to study the catalase(CAT)activity,malondialdehyde(MDA)content,soluble sugar(SS)content,and soluble protein(SP)content of seedlings under different salt stresses.The effects of SS and SP content,combined with the membership function method,were used to comprehensively evaluate the salt tolerance of the14alfalfa hybrid combinations.The hybrid combinations reacted differently to different concentrations of salt stress.The comprehensive evaluation of the alfalfa hybrid combinations showed that the best salt tolerance of alfalfa hybrid combinations occurred in Knight-2(2010)×MS-GN,WL319HQ×MS-GN,Victorian×MS-GN,Adrenalin×MS-GN,and Gannong No.3×MS-GN.
