云南特色油料植物青刺果侧芽诱导技术优化

Optimization of lateral bud induction technology of Yunnan characteristicoil plant

青刺果,属蔷薇科李亚科扁核木属植物。由于青刺果具有十分广泛的应用价值,合理有效地开发利用青刺果已产生巨大的经济、社会和生态效益,已逐步成为地方经济转型升级的支柱产业之一。本研究通过对青刺果侧芽诱导,深入探究青刺果侧芽诱导技术方法。通过对青刺果外植体的组织培养发现,以MS培养基为基质,在含基质4.74g/L、糖30 g/L、琼脂6.5 g/L的母液中加入0.5mg/L 6-BA(细胞分裂素)和0.1mg/L IBA(生长素)的培养基,对于青刺果侧芽的诱导效果最佳。本研究对青刺果种植资源进行良种繁育、繁育驯化、育苗、栽培管理等方面可提供技术支持。

The thorn fruit is a genus of the genus Rosaceae. Because of the wide application value of green thorn fruit.The rational and effective development and utilization of green thorn fi＇uit has produced enormous economic, social and ecological benefits. It has gradually become one of the pillar industries for the transformation and upgrading of the local economy. In this study, the lateral bud induction technique of the thorn fi＇uit was deeply explored. Through the tissue culture of the thorn fruit explants, MS medium as matrix, containing matrix 4.74g / L, sugar 30 g / L, agar 6.5 g / L, it was found that the medium of 0.5 mg/L 6-BA （cytokinin） and 0.1 mg/L IBA （auxin） was added on the basis of MS medium. The lateral buds have the best induction effect. This study can provide technical support for the cultivation of green thorn fruit cultivation, breeding, domestication, seedling cultivation and cultivation management.
