基因库中２１个美洲黑杨无性系的抗寒性徐红，张崎纹，陈一山，解荷峰关键词美洲黑杨无性系，抗寒性，电导率，膜脂脂肪酸不饱和度美洲黑杨（ＰｏｐｕｌｕｓｄｅｌｔｏｉｄｅｓＭａｒｓｈ）无性系具有生长迅速，抗病虫性较强等优良性状。历史上引种成功的几个美洲黑杨无性...
Populus deltoides Marsh.clones planted in the gene-library in Changqing
County,Shangdong Province were used as experimental material to measture their electrolyte
permeability and ratio of the unsaturated to sattirated fatty acid in the cell membrane as
indexes of cold resistance,The results show that the clones with high cold resistance are
No.87,78,91,113,100,those with low cold resistance are No. 36,135,50,30.Those clones with
high cold resistance can be expected to be cultivated in further northern regions.
