| 摘 要： | 用含0％、0．1％、0．2％、0．3％、0．4％五种Nacl浓度的修改MS培养基胁迫马铃薯脱毒试管苗的办法，鉴定马铃薯品种的抗盐性。结果表明，随着盐浓度的升高，试管苗受影响的程度加重，其试管苗株高、根长、干物质及生物产量间差异显著，最后确定0．3％Nacl胁迫为临界浓度。

| Abstract: | The plantlets in vitro of 3 potato cultivars with different salt resistance were treated bythe MS medium containing 0% 10.1% 10.2%. 0.3% and 0.4% sodium chloride, in order toscreen salt, resistant cultivars. Tile results shqwed that the higher salt concentration, themore inhibited effect was. In addition , it showed that the difference between the five treatments were highly significant on the plant height, root length, dry matter accumulation and,the biology yields. Finally, the optimum. Nacl concentration of 0. 3 % was established as acritical vallue to sereen salt resistance of potato cultivars (clones ) cultured, in vitro. |
