摘要/Abstract

摘要： 以18种（品种）不同地理分布及不同抗寒力的绣线菊为试验材料，通过测定露地自然低温下的抗寒性相关生理指标，应用隶属函数模型、Logistic方程计算生理指标隶属函数值；通过测定冰冻处理枝条电导率计算其半致死温度，根据生理指标隶属函数值和半致死温度确定其抗寒力。结果表明，华北绣线菊、土庄绣线菊、绒毛绣线菊、石蚕叶绣线菊、绢毛绣线菊、金丝桃叶绣线菊、三裂绣线菊抗寒力最强；毛果绣线菊、石棒绣线菊、柳叶绣线菊抗寒力较强。

关键词: 绣线菊, 抗寒性, 半致死温度, 隶属函数值

Abstract: Eighteen species or varieties of Spiraea were used as the experimental materials，which had different geographic distributions and different cold resistances. The physiological indexes which were related to cold resistance were determined under the natural low temperature in the open field. The subjection function model and Logistic equation were considered to calculate the subjection function value of the physiological indexes，and semi-lethal temperature was calculated through measuring the electrical conductivity of branches with frozen treatments. According to the subjection function value of the physiological indexes and the semi-lethal temperature to determine their cold resistant abilities. The results showed that S. fritschiana Schneid，S. pubescens Turcz，S. velutina Franch，S. chamedryfolia L.，S. sericea Turcz，S. hypericifolia L. and S. trilobata Linn were screened out as the ones which had the strongest cold resistances，also S. trichocarpa Nakai，S. media Schmibt and S. salicifolia Linn as the ones which had the stronger cold resistances.

Key words: Spiraea, cold resistance, semi-lethal temperature, subjection function value
