This work aimed to describe the foliar anatomy of seven species of Eucalyptus, emphasizing the characterization of secretory structures and the chemical nature of the compounds secreted and /or present in the leaves. Anatomical characterization and histochemical evaluation to determine the nature and localization of the secondary compounds were carried out in fully expanded leaves, according to standard methodology. Anatomical differences were verified among the species studied, especially in E. pyrocarpa. Sub-epidermal cavities were the only secretory structures found in the seven species studied, with higher density in E. pellita and lower in E. pilularis. The following compounds were histochemically detected: lipophilic compounds, specifically lipids of the essential or resin-oil type and sesquiterpene lactones found in the lumen of the cavities of the seven species; and hydrophilic compounds, of the phenolic compound type found in the mesophyll of all the species studied and on the epidermis of some of them. The results confirmed the complexity of the product secreted by the cavities, stressing the homogeneous histochemistry nature of these compounds among the species. However, the phenolic compounds results may be an indication of important variations in adaptations and ecological relations, since they show differences among the species. |
