[Objective]To discuss on the effects of different water temperatures on the seed germination indicators 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 ( CK) ,20,25,35 and 45 ℃. Germination rate,germination index,germination energy and vigor index of C. lasiandra seeds were determined. [Result]The results showed that the appropriate temperature for C. lasiandra seeds 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 germination indices of C. lasiandra seeds were the highest.
