R e su lts indicated that the seed s of L esp edeza f loribunda had the characteristic of forcing dorm ancy that wa s cau sed by hard seed ve ssels. The dorm ancy cou ld be relea sed by soak ing in hot water and by su lp hu ric acid treatm en t. The mo st app rop riate treatm en t tim e wa s 10 ～30 m in , re su lting in average germ ination rate ( 96% ) , average germ ination power ( 82. 53% ) and average germ ination index ( 17. 54 ) . The op tim um germ ina tion temp eratu re wa s 25 ℃ and
