苦丁茶繁殖特性与繁育技术研究

Propagation Characters and Grow Seedling Technique of Kudingcha (Ligustrum robustum)

贵州野生苦丁茶（ＬｉｇｕｓｔｒｕｍｒｏｂｕｓｔｕｍＢｌ．）人工播种后发芽率仅５％左右，采用１５０ｍｇ／ｋｇ赤霉素液浸种２４ｈ，可有效解除抑制，提高发芽率至６０％以上。苦丁茶种子萌发过程需要适当的光照，育苗应浅播浅盖。扦插繁殖：１～２年生枝条和当年生绿枝扦插成活率为３７％左右，老枝成活率仅１８％；应用吲哚丁酸、生根粉等处理插条可提高成活率，对老枝插条处理效果更显著。

Artifical planting of wild Kudingcha (Ligustrum robustum Bl.) just begins.Only about 5% of its seeds can germinate after sowing.Before sowing the seeds should be soaked in 150 ppm gibberellic acid solution for 24 h. Sowed seeds are relieved in the retardation and its sprouting rate over 60%.Because sprouting of seeds reguire a certain light,the seeds should be sowed shallowly.The surviving rate of cutting roots with one or two years old twig are about 37%,it is only about 18% to the old branches.Cutting branches soaked in indole butyric acid or rooting powder etc.solution,the surviving rate could be increased,especially to the old branches.
