摘　　要：研究了虎皮楠等10个珍稀树种种子的萌发适宜温度。结果发现，10个树种种子的萌发温度差异较大。其中适于在较低温度（15～20℃）下萌发的种子有尖萼厚皮香、香港四照花、金叶含笑和八月桂；适于在较高温度（25～30℃）下萌发的种子有香花崖豆藤、虎皮楠和东京白克木；对发芽温度要求较宽的树种有伯乐树、椤木石楠和蓝果树。The suitable seed germination temperature of ten rare tree species in southern Jiangxi province was studied in this paper. The results showed that there were great differences in suitable germination temperature among ten different tree seeds even collected in the same area. The suitable seed germination temperature for Ternstroemia luteoflora, Dendrobenthamia hongkongensis, Michelia foveolata and Osmanthus fragrans was 15～ 20℃, while for MiUettia dielsiana, Daphniphyllum oldhami and Exbucklandia tonkinensis it was 25 - 30℃. The seed of Bretschneidera sinensis, Photinia davidsoniae and Nyssa sinonsis could be germinated at a greater range of temperatures.
