摘　　要：采集四川岷江流域、青衣江流域以及成都、雅安、天全、茂县等11个市县不同居群的野生狗牙根和野生假俭草材料,在四川农业大学草学系新试验基地内进行田间栽培试验并结合实验室测定,对其电导率进行了测定,并以此为依据鉴定其抗寒性的强弱。试验结果表明,野生狗牙根中电解质渗透率最大的是11号宜宾狗牙根(47.1%),最小的是12号宜宾狗牙根(34.6%);野生假俭草材料中电解质渗透率最大的是4号乐山假俭草(42.9%),最小的是1号雅安假俭草(27.2%);在所试材料中抗寒性最强的狗牙根是12号宜宾狗牙根,假俭草则是1号雅安假俭草。Different kind of native bermudagrass and native centipedegrass were collected from drainage area of Sichuan Mingjiang River and Qingyijiang River and in Chengdu ,Ya'an,Tianquan,Maoxian etc to cultivate in the new experimental base of Department of Grassland Science Sichuan Agricultural University.They were observed the electric conductivity .Based on the result we can know the cold resistance of it.The result of this experiment showed:among the bermudagrass the max relative leakage is Yibin No.11(47.1%) and the min relative leakage is Yibin No. 12 (34.6%).Meanwhile among native centipedegrass the max relative leakage is Leshan No.4(42.9%),and the min relative leakage is Ya'an No.1(27.2%).So we can make a conclusion that in all experimental material the cold resistance of Yibin No.12 among native bermudagrass is strongest,and Ya'an No.1 among native centipedegrass is strongest.
