对五味子实生苗地下横走茎的形态发生、发育过程进行了研究。结果表明:1a生五味子子叶腋芽可发育为地下横走茎,但其发育较缓慢,在8月下旬至9月初才发育成地下横走茎,第1片真叶腋芽和第2片真叶腋芽当年均可以发育成地下横走茎;2a生和多年生五味子植株基部的越冬芽都会发育成地下横走茎;无论是子叶腋芽还是越冬芽在转变初期与一般芽形态相似,但经过伸长生长后,其茎尖开始弯曲以适应地下生长。地下横走茎的发生部位较集中,常呈轮生状。较高节位芽的超显微结构与子叶叶芽存在较大差异,说明五味子的芽能否形成地下横走茎在其形成的早期可能就已经决定。
Studies on the morphogenesis and development of rhizome from seedling of Schisandra chinensis (Turcz.)Baill. The results showed that one-year axillary bud of cotyledon could develop to rhizome in late August-early September slowly, and both axillary bud of rough leaf and secondary euphylla would develop into rhizome finally; winter bud grown from the base of biennial and perennial plantlet also developed into rhizome; both axillary bud of cotyledon and winter bud were similar to general bud in the initial stage, while rhizome tip became bendy gradually through elongation growth. Rotiform rhizomes were concentrated in the base of stern. Ultrastructure of axillary bud on the higher node have more differences from rough leaf, it was decided in early stage that whether axillary bud of cotyledon develop to rhizome or not.
