Abstract: ‘Zhongjiao 5’and‘Xiangyan 10’were used as experimental materials , The effects of different concentration of PA (Spd , Spm) and ABA and added at different stages on regeneration from cotyledon of pepper were studied. The results are following : (1) The rate of adventitious bud elongation is increased obviously by adding 100μmol·L-1 Spm at both different and elongating stages ; The rate of elongation on ‘Zhongjiao 5’and ‘Xiangyan 10’are increased 78%, 73% respectively compared with control ; (2) The rate of adventitious bud elongation is increased significantly by adding 0.3 mg·L-1 ABA at different stages. The rate of elongation on ‘Zhongjiao 5’and‘Xiangyan 10’are increased by 52.8 % , 71.6 % respectively over the control .
