以引自亚热带北缘的８种常绿阔叶树为试材，分别对树叶、当年生枝条经过０、－１０、－２０、－３０、－４０℃冷冻处理后，用电导法、电阻法、气孔行为观察法、组织水势法对其抗寒性进行测定。并对其抗寒性指标进行了模糊聚类分析、主成分分析和模糊相似优先比分析，确定了常绿阔叶树种引种到济南的优化链． Using the eight kinds of evergreen broad-leaved trees from the northern margin of the subtropics as test materials, the leaves, the annual branches after 0, -10, -20, -30, -40 ℃ freezing treatment, the conductivity method, resistance method, Behavioral observation method and tissue water potential method were used to determine its cold resistance. The indexes of cold hardiness were analyzed by fuzzy cluster analysis, principal component analysis and fuzzy similarity priority analysis to determine the optimal chain of introduced evergreen broad-leaved species in Jinan.
