| 摘 要： | 利用扫描电子显微镜，通过管道铸型技术，对黑龙江槭树科（Aceraceae）槭树属（Acer Linn.）中8种植物导管分子的微形态结构进行了比较研究。结果表明：该属植物导管分子长度，除白牛槭 （Acer mandshurica Maxim.）较长外，其余植物种类导管分子长度在133.00～187.50 μm；导管管腔宽度，在17.06～28.00 μm之间；纹孔排列方式以对列式、互列式单独存在，或以两者形式并存；管间纹孔成群分布且大部分呈现一定形状；讨论了导管分子管腔的主要特征及其与生境的关系。

| Abstract: | By means of scanning electron microscope (SEM) and resin casting method, the morphological structure of the vessel element in plants of Aceraceae in Heilongjiang province which includes 8 species in Acer Linn. is studied, The result shows that the length of vessel element is between 187.5 μm and 133.00 μm, except for Acer mandshurica Maxim. which has large longer length than other species. The width of vessel element is between 17.06 μm and 28.00 μm. In the types of pits of vessel element, there are alternate pitting only, opposite pitting only and both. The pits between vessels are distributed in groups, most of them show some forms. The relationship between the main characters of vessel element and their habitat is studied. |
