Abstract
Germination of Lespedeza f loribunda Bunge. seedswas studied in order to p rovide cultivation and app lication in gardening and landscap ing. Results indicated that the seeds of Lespedeza f loribunda had the characteristic offorcing dormancy thatwas caused by hard seed vessels. The dormancy could be released by soaking in hotwater andby sulphuric acid treatment. The most app rop riate treatment time was 10～30 min, resulting in average germinationrate (96% ) , average germination power (82. 53% ) and average germination index (17. 54). The op timum germination temperature was 25 ℃ and the germination rate, germination power and germination index was 95% , 81% ,22. 95 respectively after treated by sulphuric acid for 20 min.
