摘　　要：以品种宁春4号为对照,对27个春小麦品系进行了室内抗盐性鉴定,对22个春小麦品系进行了抗盐性盆栽试验。结果表明,品系08m2627、08m2712的发芽率、发芽势和发芽指数受盐胁迫的影响较小,品系09m3689受盐胁迫影响较大。品系08m2770发芽期间根、芽生长受盐胁迫影响较小,品系09m3377受盐胁迫影响较大。盆栽试验可以证明,供试部分材料具有一定的抗盐能力,可选择出抗盐性优于宁春4号的优良材料。In this article, spring wheat varity Ningchun 4 as a control, the salinity tolerance of 27 spring wheat strains were identified in room, and salt resistance of 22 spring wheat strains were investigated by pot experiment. The results showed that the germination rate, germination potential and germination index of the strain 08m2627, 08m2712 has little influence on salt stress, the strain 09m3377 has great influence on salt stress. The root and bud of the strains 08m2770 during germination has little influence on salt stress, strain 09m33777 has great influence on salt stress. In general, it could select excellent materialis superior to salt resistance Ningehun 4.
