凹唇姜属(Boesenbergia O. Kuntze)和山柰属(Kaempferia L.)(姜科)叶的解剖学

摘要

Leaf anatomical variations between species of Boesenbergia (B. curtisii, B. prainiana, B. rotunda and B. plicata) and Kaempferia (K. pulchra, K. galanga, K. gilbertii, K. rotunda, K. parviflora and K. angustifolia) were studied in order to investigate anatomical variations which could be used to distinguish species. Results show that there are variations in the type of stomata, the structure of the midrib, the outlines of the leaf margin and petiole in transverse section, and the presence or absence of abaxial or adaxial hypodermis and trichomes in the lamina. The results suggest that a combination of these characters is useful in distinguishing the species studied.%通过凹唇姜属(Boesenbergia curtisii, B. prainiana, B. rotunda 和 B. plicata)和山柰属(Kaempferia pulchra, K. galanga, K. gilbertii, K. rotunda, K. parviflora 和 K. angustifolia)种间叶解剖学变化的研究，寻找能用于鉴别种的解剖学特征。结果显示变化表现在气孔的类型、中脉的结构、叶缘和叶柄横切面轮廓、叶片的远轴面或近轴面下皮层和毛状体的出现或缺如。研究表明这些特征的联合对已研究的种的鉴别是有用的。
