  • The effects of GA3,6-BA,CEPA,PP333 and CCC were experimented on length and diameter of shoots,number of staminte and pistillate per shoot,length of spike and fleabane number of Castanea mollissima. The results showed that the number of pistillate was increased significantly by spraying GA3, 6-BA and PP333 and decreased by CEPA. The number of staminte was reduced by GA3 and CEPA(50 mg·L-1 treatment promoted). The vegetative growth was promoted by GA3,6-BA and CEPA and prevented by PP333 and CCC. The length of spike was restrained by GA3 and CEPA. The number of fleabane was promoted by GA3 and PP333 and prevented by CEPA. PP333 (500,1　000 mg·L-1) were optimal recipe for enhancing the number of female flowers and fleabane number.
