为探究蜡梅花被片表层蜡质的微形态结构特征和差异性，采用扫描电子显微镜对蜡梅和山蜡梅的花被片进行观察。结果表明：蜡梅花被片表层无明显蜡质覆盖物，细胞排列平滑，内表层有加厚透明状覆盖物；山蜡梅花被片表层有厚蜡质覆盖物和表皮毛；山蜡梅、蜡梅花被片均无气孔。以上独特的结构形态对于蜡梅花开放于寒冷季节，应对外界环境胁迫可能有一定的保护作用和生态意义。

Scanning electron microscopy was used to explore the tepal microstructure of Chimonanthus praecox and C. nitens.The results showed that the tepal of C.praecox has thick,transparent covering at its inner epidermis and no wax at its outer epidermis,while the tepal of C.nitens had wax covering and epidermal hair.Stomata were not found at the tepals of both species.These morphological characteristics may confer C.praecox the environmental resistance and therefore are of significant ecological value.
