中文摘要：

[目的]了解柽柳植物在自然条件下的萌发行为。[方法]以长穗柽柳为实验材料,观察研究了种子形态与萌发特性[结果]①长穗柽柳种子平均的长、宽、千粒重分别为1011.96μm、399.94μm、38.66mg;②自然条件下长穗柽柳种子平均的发芽率、发芽势、发芽指数、发芽系数分别达到95.56%、46.67%、20.25、56.86;③各地理居群之间的种子形态及萌发特性没有显著性差异。[结论]该研究以期为长穗柽柳的引种繁育及沙丘植被保护提供参考。

英文摘要：

[Objective] The aim was to study the germination behavior of Tamarix elongata Ledeb.under natural conditions.[Method] By using T.elongata as the experimental materials,the seed morphology and germination characteristics were observed and measured.[Result] ① T.elongata seed was 1 011.96 μm in length and 399.94 μm in width,and the thousand-seed weight was 38.66 mg;② the germination rate,germination energy,germination index and germination coefficient of T.elongata seeds were 95.56%,46.67%,20.25 and 56.86 respectively;③ there were no significant differences in morphology and germination characteristics among the three different geographical populations.[Conclusion] The present research will provide reference for the introduction and breeding of T.elongata as well as the protection of sand dune vegetation.
