摘要
采用电导法测定了 11个黑杨派无性系的枝条经不同低温处理后的电解质渗出率 ,探讨其之间的抗寒性差异 ,并测出其半致死温度均在 - 2 3℃～ - 2 9℃。
Treated under different low temperatures, the electrolyte seepage percent of shoots of 11 poplar clones of Aigeiros were measured to study the cold-tolerance differences between them using the method of electrical conduction. According to the result, the median lethal temperature of all clones is -23℃～-29℃.
