| 采用正交试验设计法,研究了NAA、KT、2,4-D、蔗糖浓度和不同外植体类型等因素对银杏愈伤组织诱导的影响。结果表明:不同外植体类型对银杏愈伤组织诱导率影响最大,KT和NAA其次,2,4-D和蔗糖浓度最小。银杏愈伤组织诱导最佳培养基为MS+NAA 0.5 mg·L-1+KT 0.5 mg·L-1+蔗糖40 g·L-1,最佳外植体为茎段,其愈伤组织诱导率可达100%。 |

| Abstract: |
| Effects of NAA,KT,2,4-D,sucrose concentration and explants type on the callus induction of Ginkgo biloba were investigated by orthogonal test in this paper. The results showed that explants type was the most important factor among the five factors for callus induction of G. biloba,followed by KT and NAA concentration,while 2,4-D and sucrose concentration were the weakest. The best medium for callus induction of G. biloba was MS+NAA 0.5 mg·L-1+KT 0.5 mg·L-1+sucrose 40 g·L-1,and stem was the best explants. With the stem as explants and with the optimal medium as the culture medium,the highest rate of callus induction in G. biloba was up to 100%. |
