摘要: 以'易丰'女贞(Ligustrum lucidum'Yi Feng')当年新发半木质化带腋芽茎段为外植体,以芽繁芽的方式,建立了较为完善的可用于大规模工厂化生产的组培快繁技术体系。研究表明,最佳诱芽(启动)培养基为WPM+0.3 mg/L Kinetin(KT)+0.1 mg/L 6-Benzylaminopurine(6-BA)+0.05 mg/L 1-Naphthylacetic acid(NAA),腋芽萌发率达到95.6%;最佳的增殖培养基为WPM+0.5 mg/L KT +1.0 mg/L 6-BA +0.05 mg/L NAA,平均增殖系数达到5.63;最佳的生根培养基为1/2WPM+1.5 mg/L 3-Indolebutyric acid(IBA)+0.1 mg/L NAA,生根周期约为20 d,生根率约为95.4%,炼苗移栽后成活率达到95%以上。建立的组培技术体系能够满足产业化生产的需要,得到的组培苗后代能够稳定地遗传亲本的优良变异性状。

Abstract: Ligustrum lucidum'Yi Feng', a wild and variant species, because its resource was very scarce, and routine methods could not achieve large-scale propagation during a short period of time, a relatively perfect tissue culture and rapid propagation system for massive production was established in this research with axillary buds of young branch cuttings as explant materials. The results showed that, the optimal initial medium was WPM+0.3 mg/L KT +0.1 mg/L 6-BA +0.05 mg/L NAA, and the germination frequency of axillary buds reached 95.6%;the optimal proliferation medium was WPM+0.5 mg/L KT +1.0 mg/L 6-BA +0.05 mg/L NAA, and its average proliferation coefficient reached 5.63;the optimal rooting medium of shoots was 1/2WPM+1.5 mg/L IBA +0.1 mg/L NAA. After about 20 days, the overall frequency of shoots rooting reached about 95.4%. And then, more than 95% of the plantlets could survive on the substrate soil in the end. The system can satisfy the need of industrial production, and the plantlets can steadily inherit the outstanding variation character of parents.
