Seed hardness is a big problem for Chamaecrista rotundifolia cultivation. A experiment was conducted to determine the impact of seed soaking treatments （hot water and H2 SO4 ） on germination of two varieties of C. rotundifolia （cv. Minyin and cv. Minyin NO. 2） for finding a technique to break seed dormancy of C. rotundifolia seed. This study showed that seeds hardness rate of two varieties reached 56.3% and 76.0%, respectively;however, the hardness rate of Minyin treated by 100 ℃ water for 3 min decreased to 11.7 %, and its germination rate and germination index increased to 42.7 % and 32.1 respec tively. The hot water treatments did not work on the seed hardness rate of Minyin NO. 2. Seeds of Minyin and Minyin NO. 2 treated by 98% H2SO4 for 10 min performed better, and indicating that their germina- tion indexes were 58.9 and 37.0 and their germination rates were 64.7% and 80.0%, respectively.%为寻求圆叶决明（Chamaecristarotundifolia）种子硬实破除技术，开展热水和硫酸浸种处理对2个圆叶明品种种子萌发的影响试验。结果表明，未浸种条件下闽引圆叶决明、闽引2号圆叶决明种子硬实率分别56．3％、76．0％。初始温度为100℃热水浸种3rain，闽引圆叶决明种子硬实率降至11．7％，发芽率升至42．7乡发芽指数达32．1，高于其他热水浸种处理。不同热水浸种处理闽引2号圆叶决明的种子硬实率无显著差爿98％硫酸浸种10min，闽引圆叶决明、闽引2号圆叶决明的种子硬实率分别降至1．3％、
