摘　　要：以长春市繁荣路的行道绿化树种垂爆109柳为观测材料,对其抗寒能力进行调查与分析,结果表明:在2009年至2010年冬春季节的温度条件下,冻害发生严重,有整株死亡现象,3个地段的冻害指数分别为52.8、43.5和32.2,平均冻害指数为42.8,受害率达到80%以上。在2010年至2011年冬春季节的温度条件下,冻害相对较轻,无死亡植株发生,但枯梢现象仍比较严重。冬春季节温度低且持续时间长形成的累积效应是导致冻害发生的主要因素,此外,还与植株的生长势以及是否感染病虫害有一定关系,而与遗传性没有必然联系。The cold-resistance of Salix × ＇Chuibao109＇ growing on the Fanrong road was investigated and analyzed in Changchun city.The cold injury was serious during 2009 winter and 2010 spring because of low temperature.The cold injury index were 52.8%,43.5% and 32.2 in three places,with the average at 42.8%,and the injury percentage was above 80%.The cold injury was relative slight during 2010 winter and 2011 spring.There was no dead plant,but phenomenon of dried top was serious.The long-term accumulative effect of low temperature in winter and spring was the main factor for the occurrence of cold injury of this tree.Furthermore,cold injury was also related with the growth potential and health of plants,but no inevitable relationship with the heredity.
