对21份国外引进的野生偃麦草属种质材料在不同梯度NaCl胁迫下,通过存活率、株高、根茎比、生长胁迫指数和叶片伤害率的测定,利用主成分分析法和隶属函数法,综合评价其耐盐性.结果表明:随着盐浓度增大,偃麦草属材料除伤害率外,其它指标与对照相比均有所下降.根据综合评价值可知,其耐盐性由强到弱为ZXY03P-388,ZXY03P-349,ZXY03P-433,ZXY04P-210,ZXY04P-257,ZXY04P-77,ZXY03P-463,ZXY03P-480,ZXY04P-25,ZXY03P-368,ZXY03P-491,ZXY04P-176,ZXY04P-29,ZXY04P-490,ZXY04P-6,ZXY03P-444,ZXY04P-103,ZXY03P-318,ZXY03P-271,ZXY03P-289,ZXY04P-157.
對21份國外引進的野生偃麥草屬種質材料在不同梯度NaCl脅迫下,通過存活率、株高、根莖比、生長脅迫指數和葉片傷害率的測定,利用主成分分析法和隸屬函數法,綜閤評價其耐鹽性.結果錶明:隨著鹽濃度增大,偃麥草屬材料除傷害率外,其它指標與對照相比均有所下降.根據綜閤評價值可知,其耐鹽性由彊到弱為ZXY03P-388,ZXY03P-349,ZXY03P-433,ZXY04P-210,ZXY04P-257,ZXY04P-77,ZXY03P-463,ZXY03P-480,ZXY04P-25,ZXY03P-368,ZXY03P-491,ZXY04P-176,ZXY04P-29,ZXY04P-490,ZXY04P-6,ZXY03P-444,ZXY04P-103,ZXY03P-318,ZXY03P-271,ZXY03P-289,ZXY04P-157.
