中金系列杨树的组培技术研究

中金系列杨树是杨柳科杨属白杨派植物,选择其腋芽（或顶芽）、嫩茎段、嫩叶片等为外植体,进行愈伤组织诱导试验、不定芽分化试验、生根试验,筛选出了适合植株分化、生根的培养基成分;对生根试管苗进行移栽基质配比试验,确定组培苗最佳生长环境。总结出适合中金系列杨树组培的技术流程,保证了杨树的遗传稳定性,降低了培养成本,加快了培养速度。

The Tissue Culture Technique of Zhongjin Series Poplar

Zhongjin series poplar belongs to the genus of populus,family of salicaceae.Selecting axillary bud or terminal bud,shoot segments,Callus,etc.as explants,the experiments of callus induction,adventitious bud differentiation and rooting were carried on.The medium components were screened for plant differentiation and rooting.The optimal growth environment of tissue culture seedlings was determined with matrix combination through transplanting rooting tube plantlets.The technical process was summarized for Zhongjin series poplar in tissue culture,ensuring hereditary stable,lowering the cultivation costs and improving the cultivation speeds.
