组织培养技术用于泡桐优良品种无性系的快速繁殖,能尽早稳定杂种后代性状,缩短育种年限,提高选种效率。一株无菌苗一年可增殖10—20万株苗,所以组织培养是一个多、快、好、省方法。目前对泡桐无菌实生苗的茎尖、茎节及根萌发芽虽已培养成再生植株,但因培养基内激素及其浓度、无机盐、铁盐含量的多少及培养基的不同配方,对各种组织再生的影响不同。为了探索泡桐叶,隐芽的再生规律,作者在杭州植物园组培组老师们的指导
Tissue culture technology for rapid propagation of elite Paulownia clones, as soon as possible to stabilize hybrid offspring traits, shorten the breeding life, improve the selection efficiency. A sterile seedlings can proliferate 10-20 million seedlings a year, so tissue culture is a more, faster, better, provincial method. At present, although the stem tips, stem nodes and root sprouting of the sterile seedlings of Paulownia have been cultured into regenerated plants, due to the hormones and their concentrations in the medium, the content of inorganic salts and iron salts and the different formulas of the medium, The effects of various tissue regeneration are different. In order to explore the Paulownia leaf, hidden buds of the law of regeneration, the author of the Hangzhou Botanical Garden tissue culture group of teachers guidance
