不同生境的金露梅解剖特征比较

THE COMP ARATIVE STUDY ON THE ADAPTION OF DASIPHORA FRUTICOSA'S ANATOMICAL CHARACTERS IN DIFFERENT ECOLOGICAL ENVIRONMENT

通过对青藏高原东北部不同海拔高度金露梅茎、叶形态和解剖结构的比较观察发现：金露梅共同表现出叶为异面叶，叶表皮细胞单层，栅栏组织细胞均两层，茎中通气组织发达等特征，此外其形态结构依不同生境发生规律性的变化。这些变化是植物对温度、水分、太阳辐射、海拔高度等自然条件改变的整体适应。

According to the comparative reserch of Dasiphora fruticosa's morphological and anatomicalcharacters in the different altitude in the east-northern part of Qinghai-Tibetan Plateau, Wehave discovered that their characters have regular changes with different ecological environment.These changes are the adaptation for the difference of temperature, water, solar radiation and thealtitude etc.
