| 摘 要： | 描述分枝假槟榔的形态特征,并对其成因进行分析。认为假槟榔这个侧枝是直接从主干叶腋中由茎花芽逆转后萌发生成,为偶发分枝,其生长方式与花苞类似,但这个叶鞘包被的是叶芽而不是花芽,由于营养生长相对于主干较弱,侧枝比主干略小,侧枝的环痕间距也比主干窄。

| Abstract: | Morphogenesis of the branching stems was analyzed in palm plants.A branching plant stem of Archontophoenix alexandrae Lour was found firstly in the campus of Fujian Agriculture and Forestry Unversity,and its morphological character and morphogenetic causation was studied in this paper.A.alexandrae was mainly trees in landscape campus of Fujian Agriculture and Forestry University,branching stem was not found generally in single palm plant.The branching stem of A.alexandrae occored directly from detorsion of flower primordium into leaf primordium,it was occasional branching stem,and its growth way was the same as the calyx which grown a budding leaf with leaf sheath.The branching stem of A.alexandrae was less than main stem,and the interval of annular leaf trace in the branching stem was also less than main stem,because their nutrient distribution was relatively deference between the branching stem and the main stem. |
