中国苎麻属植物比较形态学研究

在同地种植条件下，苎麻属16种7变种的主要植物形态特征比较研究表明：1.根有分枝根型、浅直根型和萝卜根型。2.茎有直立茎型、斜倚茎型和匍匐茎型。3.部分种的植物形态特征在不同生长发育阶段有明显变化。4.花序为簇生花序组成的穗状花序或复穗状花序或单个腋生，是典型的“具小叶的”花序类型和“具苞片的”花序类型的过渡花序类型。分析了该属植物外部形态的演化趋势及组间亲缘关系。

The Comparative Morphology of Boehmeria in China

species and 7 varieties were used as materials for comparative study on botanical morphology in Boehmeria. The result showed , 1 . Root could be classified as branching root , shallow streight root and storage root. 2. Stem could be classified as erect stem , creeping stem and slope stem. 3. There were obvious variation on botanical mor- phology traits in some species at different growing stage. 4. It was spike or compound spike or individual inflorescence , which was made fascicled inflorescence. The evolution- ary trend of botanical morphology and affinity of five groups were discussed in this paper.
