| 摘 要： | 目的]探讨不同水温浸种对毛蕊铁线莲种子发芽指标的影响,为毛蕊铁线莲种子繁殖提供理论和实践依据。方法]利用恒温培养箱,经10和15℃（室温条件下的自来水温度,以此作为对照,CK）,20、25、35和45℃的恒温水浸种48 h后,测定毛蕊铁线莲种子发芽率、发芽指数、发芽势及活力指数5个指标。结果]毛蕊铁线莲种子水温浸种的适宜温度为20℃,其发芽率为80.7%,发芽指数为6.184,发芽势为54.0%,活力指数为9.442。结论]20℃水温浸种后毛蕊铁线莲种子的各项发芽指标最高。

| Abstract: | Objective]The aim was to discuss on the effects of different water temperature on the seed germination indexes of Clematis lasiandra Maxim,in order to supply theoretical and practical basis for its reproduction.Method]seeds were soaked in constant-temperature incubator under 10,15,20,25,35,and 45 ℃.Germination rate,germination index,germination energy,vigor index,of Clematis lasiandra Maxim were determined.Result] The results showed that the appropriate temperature for seeds of Clematis lasiandra Maxim was 20 ℃.The germination rate was 80.7%,germination index was 6.184,germination energy was 54.0%,and the vigor index was 9.442.Conclusion] After soaking in water under 20 ℃,the indices of Clematis lasiandra Maxim germination were the highest. |
