Anatomía y arquitectura foliar
caso del género Zanthoxylum (Rutaceae)
Abstract
Plant anatomy is a biological discipline that studies morpho-anatomical structures; facilitates the understanding of these structures over time and their interrelation with the environment; which contributes to problem solving in areas such as botany and ecophysiology through the study of structure, provides us with information and data that offer tentative solutions for taxonomic aspects. This paper addresses an example of the use of these leaf characters in 12 Mexican species of the genus Zanthoxylum. The method used was the diafanization of leaves and anatomy microtechnique of inclusion in paraffin to obtain histological cuts. Species are characterized by the presence of oil glands, diversity in trichomes (simple, multicellular, starry, and pelted); patterns are recognized in the arrangement of the glands and characteristics of the leaf anatomy are described as petiole forms, vascular system, presence of fibers and parenchyma in palisade with one or two stratums. A greater diversity of forms is observed in Mexican species.
