[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.
