| 摘 要： | 为选育抗旱性强的狗牙根优质品种,运用模糊数学隶属函数法对10份狗牙根种质的植株生长高度、叶绿素含量、叶片相对含水量、细胞膜透性、可溶性蛋白质含量、POD酶活性、SOD酶活性、脯氨酸和丙二醛等9项指标进行抗旱性综合评价。结果表明,10份种质的抗旱性强弱顺序为：福建A478〉海南A373〉海南A185〉海南A476〉福建A492〉江苏A72〉江苏A25〉上海A330〉河南A237〉云南A301。

| Abstract: | For breeding Cynodon dactylon varieties with better drought resistance,membership function of fuzzy mathematics was used to comprehensively evaluate 10 Cynodon dactylon varieties filtrated preliminary about the plant height,chlorophyll content,relative water content in leaf,permeability of cell membrane,content of soluble protein,POD,SOD,praline and MDA.The capability order of drought resistance of the 10 varieties was: A478(Fujian)>A373(Hainan)>A185(Hainan)>A476(Hainan)>A492(Fujian)>A72(Jiangsu)>A25(Jiangs... |
