Abstract: In this paper, the effects of MgCl₂ solution, KCl solution and normal temperature deionized water（ck） soaking treatment on germination characteristics of Rhodomyrtus tomentosa provenances from 21 different regions distributed naturally in 6 provinces in China were investigated. The results showed that there were significant differences in germination rate, germination index and germination potential among different provenances under ck treatment, the higher germination rate, germination index and germination potential of R. tomentosa provenances were found in Huiyang of Guangdong, Lianjiang of Guangdong, Du’an of Guangxi and Lingao of Hainan. Compared with ck, seed-soaking treatment with MgCl₂ solution significantly reduced the germination rate of provenances from Dapeng of Guangdong, Lianjiang of Guangdong, Luchuan of Guangxi, and Lingao of Hainan, but significantly increased the germination potential of provenances from Liancheng of Fujian, Huiyang of Guangdong, and Dapeng New District of Guangdong. The germination rate, germination index and germination potential of provenances from Chaoan of Guangdong and Luchuan of Guangxi were significantly decreased by soaking seeds with KCl solution.
