摘要
利用播种、扦插和组织培养 3种方式繁殖变色秋海棠均获得成功。播种繁殖的发芽率约 60 % ;在 3种不同的叶插繁殖中 ,以锥形叶插成活率最高 ;组织培养以叶片为外植体、MS+BA1 +NAA0 .1固体发芽培养基较好 ,从外植体直接分化出芽原基和新芽 ,属于器官型再生方式。利用密闭容器栽培法或类似此种方法栽培变色秋海棠 ,取得较好效果。
Begonia versicolor can be propagated by seeds, cutting and tissue culture. The germination rate of seeds is about 60%. Cone leaf cuttings and wedge leaf cuttings were more applicable to leaf cuttings. New budlets grew out directly from leaf explantations by tissue culture in solid medium of MS+BA+NAA 0.1 in about 60 days without producing callus. It is a good way of using enclosed containers or similar ways for cultivating B. versicolor.
