摘要: 以铁线莲品种‘MultiBlue’的茎尖为外植体,1/2MS为基本培养基,进行胚性愈伤组织和体细胞胚的诱导及植株再生条件的选择。结果表明:茎尖外植体在1/2MS+TDZ(1.0 mg/L)+NAA(0.5 mg/L)+2 %蔗糖+0.7 %琼脂的固体培养基中培养时可形成淡黄色块状至颗粒状愈伤组织,经继代培养后可逐渐形成胚性愈伤组织;体细胞胚诱导以1/2MS+TDZ(0.2 mg/L)+IBA(0.1 mg/L)+ABA(0.3 mg/L)+CH(0.5 g/L)为佳,诱导率可达96 %;而适宜的体细胞胚萌发培养基为1/2MS+6-BA(0.2 mg/L)+IBA(0.05 mg/L)。体胚再生植株经驯化后,移 栽成活率可达80 %以上。

Abstract: Using stem tip of Clematis ‘MultiBlue’ as explants and 1/2 MS as culture media, the suitable conditions for induction of embryogenic callus and somatic embryos, as well as plant regeneration, were determined. The results indicated that the optimal conditions for induction of embryogenic callus were 1/2 MS supplemented with 1.0 mg/L TDZ, 0.5 mg/L NAA and 2 % scourse plus 0.7 % agar. Explants cultured in this solid medium could form yellow massive or granular callus and produced embryogenic callus after subculture. Suitable media for somatic embryo induction were 1/2 MS added with 0.2 mg/L TDZ and 0.1 mg/L IBA plus 0.5 g/L CH, with an induction rate of 96%. The germination rate of somatic embryos was the highest when the plant growth regulators were 0.2 mg/L 6BA and 0.05 mg/L IBA. The plantlets with root were successfully transplanted to the medium with vermiculite. The survival rate of regeneration plant could be up to at least 80 %.
