猫尾草属牧草苗期耐盐性评价

孙桂枝;张耿;王赞;王运琦;高洪文

  对16份引自俄罗斯的野生猫尾草属(Phleum pratense)材料,在0.3%,0.4%和0.5%NaCl胁迫下,通过株高、存活率、叶片伤害率的测定,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16份猫尾草属牧草在0.3%,0.4%和0.5%NaCl胁迫下存活率分别为30%~83%,13%~67%和7%~57%。根据耐盐性综合评价值(D)得出猫尾草耐盐性顺序,ZXY03P-465>ZXY03P-168>ZXY03P-149>ZXY03P-389>ZXY03P-117>ZXY03P-81>ZXY03P-240>ZXY03P-370>ZXY03P-290>ZXY03P-64>ZXY03P-17>ZXY03P-340>ZXY03P-135>ZXY03P-186>ZXY03P-419>ZXY03P-33。……
