摘　　要：The effects of GA3,6-BA,CEPA,PP333 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 GA3, 6-BA and PP333 and decreased by CEPA. The number of staminte was reduced by GA3 and CEPA(50 mg·L-1 treatment promoted). The vegetative growth was promoted by GA3,6-BA and CEPA and prevented by PP333 and CCC. The length of spike was restrained by GA3 and CEPA. The number of fleabane was promoted by GA3 and PP333 and prevented by CEPA. PP333 (500,1　000 mg·L-1 ) were optimal recipe for enhancing the number of female flowers and fleabane number.The effects of GA3,6-BA,CEPA,PP333 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 .
