摘要:

以海滨木槿(Hibiscus hamabo)带腋芽茎段为试验材料,采用组织培养法,研究不同消毒处理对外植体的影响,以及不同植物生长调节剂对腋芽诱导、增殖培养、生根培养的影响。结果表明,海滨木槿外植体最适宜消毒的方法为50% 84消毒液处理15 min,污染率为0,褐化率为12.22%;最适宜的诱导培养基为基本培养基(MS)+30 g·L-1蔗糖+7 g·L-1琼脂+0.5 mg·L-1 6-苄基腺嘌呤(6-BA)+0.05 mg·L-1萘乙酸(NAA),萌芽率为88.89%;最适宜的增殖培养基为MS+30 g·L-1蔗糖+7 g·L-1琼脂+1.0 mg·L-1 6-BA+0.20 mg·L-1 NAA,增殖系数为2.01;最适宜的生根培养基为1/2 MS+30 g·L-1蔗糖+7 g·L-1琼脂+0.1 mg·L-1 IBA,生根率可达91.11%。该研究建立了完善的海滨木槿组培快繁体系,为海滨木槿遗传转化育种及工厂化生产提供参考依据。

Abstract:

Hibiscus hamabo with axillary bud stem segment was used as the test material. The effects of different disinfection treatments on explants and the effects of different plant growth regulators on axillary bud induction, proliferation culture and rooting culture were studied by tissue culture method. The results showed that the most suitable disinfection method for Hibiscus hamabo explants was 50% 84 disinfectant for 15 min, the contamination rate was 0, and the browning rate was 12.22%. The most suitable induction medium was MS+30 g·L-1 sucrose+7 g·L-1 agar+0.5 mg·L-1 6-BA+0.05 mg·L-1 NAA, and the germination rate was 88.89%. The most suitable medium for proliferation was MS+30 g·L-1 sucrose+7 g·L-1 agar+1.0 mg·L-1 6-BA+0.20 mg·L-1 NAA, and the proliferation coefficient was 2.01. The most suitable rooting medium was 1/2 MS+30 g·L-1 sucrose+7 g·L-1 agar+0.1 mg·L-1 IBA, and the rooting rate was 91.11%. In this study, a complete tissue culture and rapid propagation system of Hibiscus hamabo was established, which provided a reference for genetic transformation breeding and factory production of Hibiscus hamabo.

Key words: Hibiscus hamabo, stem segment, tissue culture, rapid propagation
