Effect of 6-BA and 2, 4-D on Soybean Transformation

Regeneration from cotyledonary nodes and embryonic tips of soybean "Peking" was studied. The disinfectant ways of the mercuric chloride and chlorine gas were used and the concentrations of 6-BA and 2, 4-D were studied in the culture medium. The results showed that the sterilization effect of chlorine gas was better than that of mercuric chloride. The best concentration of 6-BA was 1.0 mg · L-1 and the best concentration of 2, 4-D was 2.0 mg · L-1 in the germinating medium. The number of buds of each explant was 3.56 and 2.98, respectively. The best concentrations of 6-BA and 2, 4-D were 3.0 mg·L-1 and 3.5 mg·L-1 in regeneration of embryonic tips. The best inducing time was 16-20 h and the mean shoots per explant was 2.69 and 2.78, respectively.
