| 摘 要： | 以14个结缕草品种(系)为试验材料,以马尼拉和天鹅绒为对照,用电解质渗透法作为指标,比较它们的抗寒性。结果发现:与天鹅绒相比,除了引自中国台湾的Z095的抗寒性较差外,其它几个国产品种(系)的抗寒性都较强;与马尼拉相比,引自中国山东枣庄的Z116的半致死温度与其相同,国外引进品种的抗寒性则较差或与其接近。

| Abstract: | The low temperature tolerance (LTT) of 14 cultivars of Zoysia willd. and the control Tianerong and Manila was studied by means of electrolyte leakage rate in May, 2003. The results showed that the LTT of all the domestic cultivars except Z095 was better than that of Tianerong. The LT_(50) of Z116 was the same as that of manila and LTT of all the overseas cultivars was worse than or close to that of manila. |
