| Summary: | The effects of factors including seedling age, different combinations of BA and NAA concentrations, Agar concentration, AgNO<sub>3</sub> and GA<sub>3</sub> on bud induction from cotyledon are analysed. The results indicate that the explants from 5-9 days old seedling are the most efficient to induce adventious buds. The concentration of BA is the key factor to adventious buds differentiation. BA lower than 2 mg/L, is harder to induce adventious buds. The combinations of 6 mg/L BA and 0.05 mg/L NAA can improve adventious buds induction. The culture medium with 12 g/L Agar, 5 mg/L AgNO<sub>3</sub> and 2-3 mg/L GA<sub>3</sub> can increase the frequence of differentiation. According to these results, a procedure for induction of adventious buds and regeneration system for Chinese cabbage is estabished. By using this system, high regeneration frequence can be obtained, but could be affected by genotypes. |
