Abstract:
To compare regeneration capacities of two kinds of explants in soybean (Glycine max L.),the induction rate,number and length of adventitious buds were investigated with embryonic tips and hypocotyls as explants.The results showed that the adventitious bud production depended on the genotypes applied in soybean.In the embryonic tip regeneration system,the maximum induction rate of adventitious buds was observed in Jilin 35,and the maximum number of adventitious buds was observed in Jinlin 35 and Hefeng 35,while as the longest adventitious buds appeared in Heinong 44.In the hypocotyls regeneration system,desired induction rates of adventitious buds were realized in Huaidou 4,Heinong 44,Huaidou 9 and Jinlin 35.Similar number of adventitious buds were achieved in all of those genotypes except for Heinong 40 possessing less adventitious buds.Furthermore,the maximum length of adventitious buds appeared in genotypes Huaidou 9,Heinong 44 and Hefeng 35.The results indicated that Hefeng 35 had the best regeneration capacity in both regeneration systems,based on the data from induction rates of adventitious buds,number and length of adventitious buds,and their regeneration capacities.In addition,Heinong 40 may to be more suitable for embryo tip regeneration system,and Huaidou 9 was more desirable for hypocotyl regeneration system.
