| 摘 要： | 对11份引自俄罗斯的野生无芒雀麦(Bromus inermis Leyss.)材料,在0.3%、0.4%、0.5%NaCl胁迫下,通过存活率、总生物量、叶片伤害率、株高的测定,采用隶属函数法和标准差系数赋予权重法进行耐盐性综合评价。结果表明:供试11份无芒雀麦在0.3%、0.4%、0.5%NaCl胁迫下存活率分别为90%～100%,76.7%～96.7%,67.0%～96.7%;根据耐盐性综合评价值(D)得出供试材料耐盐性顺序为,ZXY04P-371>ZXY04P-255>ZXY04P-136>ZXY04P-188>ZXY04P-96>ZXY04P-503>ZXY04P-34>ZXY04P-322>ZXY04P-241>ZXY04P-46>ZXY04P-18。

| Abstract: | 4 indexes(Survival rate,total biomass,leaf damage rate and plant height)of 11 wild Bromus inermis Leyss materials from Russia were determined under NaCl stress(0.3%,0.4% and 0.5%)at seedling stage.Besides,salt-tolerance of Bromus inermis Leyss.was evaluated comprehensively by membership function method and standard deviation coefficient allocation weighted method.The results showed that survival rate was 90% to 100%,76.7% to 96.7%,67%to 96.7% under NaCl stress(0.3%,0.4% and 0.5%)respectively.According to the comprehensive evaluation value of salt-tolerance,11 Bromus inermis Leyss materials were ordered below:ZXY04P-371>ZXY04P-255>ZXY04P-136>ZXY04P-188>ZXY04P-96>ZXY04P-503>ZXY04P-34>ZXY04P-322>ZXY04P-241>ZXY04P-46>ZXY04P-18. |
