The higher the concentration of Cefotaxime was, the lower the rate of differentiation was; when the concentration of Cefotaxime was high 400~500mgL^(-1, the growth of callus was inhibited. However, the effect of Carbenicillin on callus was little and the differentiation of adventive buds was promoted under appropriate concentration. When the Carbenicillin's concentration was 200mgL^(-1), the differentiation rate reached the maximum 68.8%.

头孢霉素浓度愈大，213品种不定芽分化频率愈低，当头孢霉素浓度较高400~500mgL^(-1时，愈伤组织生长受到抑制；而羧苄青霉素对愈伤组织影响很小，在适宜的浓度下能促进不定芽分化，213品种在羧苄青霉素浓度为200mgL^(-1)时，分化频率达到最大值68.8%。
