摘　　要：[目的]了解葛萝槭种子休眠的温度特性。[方法]采用不同温度、贮藏天数和贮藏方式处理对葛萝槭种子进行发芽试验,研究最佳发芽条件。[结果]低温贮藏60 d种子发芽率最高,达25.33%,60、80 d和100 d低温贮藏发芽率无显著差异,低温贮藏40 d发芽率最低;5℃条件下种子不发芽,10℃下种子发芽率为6.67%,25℃下发芽率最高,达25.33%。4℃低温湿砂贮藏方式的种子发芽率最高,达45.10%,其次是4℃低温贮藏,常温贮藏种子发芽率极低。[结论]该研究可为培育优良的葛萝槭苗木提供科学依据。[Objective]In order to understand the dormancy temperature characteristics of Acer grosseri seeds.[Method]The germination test of Acer grosseri seeds was carried out through different temperatures,storage days and storage treatments,the optimum germination conditions were studied.[Result]The germination rate of seeds stored at low temperature for 60 days was the highest,which was 25.33%.There was no significant difference in the germination rate of seeds stored at low temperature for 60 days,80 days and 100 days,and the germination rate of seeds stored at low temperature for 40 days was the lowest.The seeds did not germinate at 5℃,the germination rate at 10℃was 6.67%,and the germination rate at 25℃was the highest,up to 25.33%.The germination rate of seeds stored in 4℃low temperature wet sand was the highest,up to 45.10%,followed by 4℃low temperature storage,and the germination rate of seeds stored at room temperature was extremely low.[Conclusion]This study can provide a scientific basis for cultivating excellent Acer grosseri seedlings.
