摘　　要：以9个不同品种仙客来幼苗为试材,通过叶片细胞相对膜透性的测定,结合叶片显微结构的观察,对仙客来不同品种间幼苗的耐热性进行了比较。结果表明:法国、日本仙客来品种耐热性最强,荷兰品种耐热性最差;仙客来叶片细胞相对膜透性和叶片表皮厚度均可作为其不同品种间耐热性鉴定指标。The heat tolerance in 9 different cultivars and seedling ages of cyclamen stocks was tested by means of the relative membrane permeability and the microstructures in leaves. The results showed that heat toleranee of France and Japanese cultivars was the highest, while that of Holland cultivars was the lowest. Microstructures and epidermis thickness of leaves could be used as indexes to identify heat tolerance in different cultivars of cyclamen.
