摘要
黄瓜离体子叶培养时，整片子叶培养形成花芽的百分率明显高于切除部分子叶的花芽形成的百分率。切除黄瓜幼苗１／２子叶明显促进黄瓜幼苗去顶芽后直接形成花芽的百分率。纵向切除１／２子叶不利于直接花芽的形成。
Cotyledons from aseptical seedlings of cucumber (cucumis sativus L. ) inoculated on modified Murashings and skoog (MS) medium, the percentage of the direct floral buds formation of the whole cotyledons was higher than those cutting out the part of cotyledonary blade. The cutting of 50% cotyledo- nany blade promoted the percentage of direct floral bud formation at the cotyledonary node region of the decapitated cucumber seedlings.
