摘　　要：以适宜新疆地区种植的彩色树种紫叶稠李为研究对象,通过低温处理,用电导法测定紫叶稠李相对电导率.并用Logistic方程拟合求拐点值来估计其半致死温度,探讨其抗寒性。结果表明,紫叶稠李的半致死温度为-35.6℃,在新疆寒冷的冬季不采取任何措施可安全过冬,是园林工程、荒山绿化树种配置的优良树种。Cold resistance color species of Padus racemosa of suitable cultivated in Xinjiang was examined, by low temperature treatment and conductivity measurement method. Semilethal temperature was determined by using Logistic equation fitting for inflection point value. The results showed that semi-lethal temperature of P. racemosa was -35.6℃, indicating that plant could overwinter safely in Xinjiang without any protection measures. It can be used as suitable tree species in landscope engineering and afforestation.
