The callus subculture and induction of adventitious bud of Zizyphus jujuba were studied in this paper. The results shown that the callus induced from stem segments could regenerate adventitious buds after being cultured 4 times. The optimal concentration of hormones was NAA 0015 mg·L~(-1)+ZT 175 mg·L~(-1) turned from NAA 30 mg·L~(-1)+ZT 20 mg·L~(-1) during the callus subculture. The difference am...
