摘要: 本研究旨在为枸杞繁育提供技术支持。在枸杞无菌苗的基础上,以茎段为外植体,在MS培养基中添加外源激素IAA、IBA、GA和NAA,考察其对枸杞离体茎段生根及生长的影响。结果发现:外源添加IAA有利于诱导枸杞无菌苗离体茎段的生根与生长,其中以1.0 mg/L浓度较为显著。培养30天后,根数达到22.03、根长为15.13 cm、根鲜重为0.6015 g/株。外源添加IAA(1.0 mg/L浓度)培养30天最有利于诱导枸杞无菌苗离体茎段的生根与生长。

Abstract: The study aims to provide technological support for breeding lycium. On the basis of lycium virus-free plantlet, the stems were used as explants, and the exogenous hormones IAA, IBA, GA and NAA were added to MS medium. Influence of those hormones on rooting and growth of lycium plantlets were investigated and analyzed. The results showed that exogenous IAA had a promoting effect on the rooting and growth of lycium stem in vitro, the effect was most significant with the concentration of 1.0 mg/L. After 30 days culture, the root number was 22.03, the root length was 15.13 cm and the fresh weight was 0.6015 g/plantlet. The treatment of exogenous IAA (1.0 mg/L) and 30 days culture was the best for promoting the rooting and growth of lycium plantlets.
