摘要
Germination of Lespedeza floribunda Bunge.seeds was studied in order to provide cultivation and application in gardening and landscaping.Results indicated that the seeds of Lespedeza floribunda had the characteristic of forcing dormancy that was caused by hard seed vessels.The dormancy could be released by soaking in hot water and by sulphuric acid treatment.The most appropriate treatment time was 10～30 min,resulting in average germination rate(96%),average germination power(82.53%)and average germination index(17.54).The optimum 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.

Results indicated that the seeds of forcing dormancy that was caused by hard seed vessels. The dormancy floribunda had the characteristic of could be released by soaking in hot water and by sulphuric acid treatment. The most appropriate treatment time was 10-30 min, resulting in average germination rate（96% ）,average germination power（82.53% ）and average germination index（17.54）. The optimum 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.
