摘要
对杜仲优树无性系试验测定林中初选的15个优良无性系在低温下的电解质渗出率及低温处理后枝条染色度进行了测定,并对其抗寒性进行了比较分析,为杜仲良种的终选和良种的推广栽培提供了理论依据。
The electrolyte permeability and coloured level of fifteen priliminary selected Eucommia ulmoides clones of plus trees were measured under different low temperature treatments. The differences of cold resistance among the fifteen clones were compared and analysed. All this provide theory proof for finaly selecting eucomia fine colones and cultivating.
