运用光学显微镜、万能显微镜、解剖镜对黄波罗、胡桃楸、水曲柳的根、茎、叶和芽的结构特征进行了比较观察。它们的叶肉细胞的形状和排列方式、角质层的厚度、毛状体类型和根、茎组成成份、分泌组织类型和分布等均有差异。这充分说明它们的结构与环境是统一的,是长期适应环境的结果。 The structure characteristics of roots, stems, leaves and buds of Huangboluo, Juglans mandshurica and Fraxinus mandshurica were observed with light microscope, universal microscope and dissecting microscope. Their mesophyll cell shape and arrangement, the thickness of the stratum corneum, trichome types and root, stem composition, secretion of tissue types and distribution are different. This fully shows that their structure is consistent with the environment and is the result of long-term adaptation to the environment.
