Ecological anatomy of Eugenia punicifolia (Kunth) DC. (MYRTACEAE) in the restinga region,state of Ceará
Abstract The species Eugenia punicifolia (Kunth) DC. (myrtle) occurs in the coastal region of the state of Ceará and has ecological and medicinal importance. This study aimed to characterize the leaf anatomy of myrtle (E. punicifolia) in the rainy and dry seasons, as well as in the sun and shade in the restinga region of the state of Ceará and to contribute to the understanding of the morphoanatomic variations in response to the natural conditions of the occurrence of this species. For this, collections of fully expanded leaves were performed at the Botanical Park of Ceará and fixed in FAA70, being replaced by 70% ethanol after 24 hours. The usual anatomical procedures were then performed in order to qualitatively and quantitatively analyze the leaf blade, petiole and epidermis structures. As a result, it was found that myrtle has xeromorphic characteristics such as thick cuticle, hypoestomatic leaf and sclerenchyma fibers in the median vein vascular bundles. It was concluded that E. punicifolia has great plasticity to adjust well under the analyzed conditions.
