Abstract

The study of the ecological anatomy of the wood seeks to detail the behavior of the tree in relation to environmental adversities. Light and water availability are determining factors for variations in anatomical and morphological characteristics in the wood of a species. Guarea Kunthiana A. Juss. (Meliaceae) occurring inside the Gruta do Janelão, occurring in the Cavernas do Peruaçu MG National Park, demonstrates different phenotypes along the length of the cave, and therefore, the objective of this work was to carry out an anatomical-ecological analysis of the wood and leaf morphology of the species. to understand the plant-environment interaction and how it affects the anatomical characteristics of wood. For this, three trees were measured in different positions in the cave, samples of wood, leaves and the light intensity of each location were collected. Then, anatomical characterization and Spearman correlation were performed to verify the influence of the environment on wood anatomy. It was observed that the anatomical components found are common to the genus and the family; proximity to water courses exerts greater influence on the amount of anatomical elements than light intensity; there is a strong association between leaf blade area and wood anatomy. It is concluded that G. kunthiana has anatomical adaptations for mesomorphic environments.
