Resumo: | The ecological foliar anatomy of the genus Myrcia DC. is still little studied. Myrcia guianensis (Aubl.) DC. species popularly known as mapirunga, occurs in a coastal region in the state of Ceará and has ecological importance and medicinal potential. The objective was to characterize the ecological foliar anatomy of this species in rainy and dry seasons, as well as, in the sun and shade in the Ceará’s Restinga. To do so, samples were collected in São Gonçalo Botanical Garden, with leaves totally expanded and fixed in FAA70, being replaced by 70% ethanol after 24 hours. It was followed to the usual anatomical procedures in the Ecology Laboratory of the Ceará State University, in order to qualitatively and quantitatively analyze the structures of the leaf blade, petiole and paradermal sections. The results showed the presence of characteristics that contribute to its survival in a Restinga environment with periods of water deficit and high luminosity, such as: presence of slightly thick cuticle, hypoestomatic leaf, increased stomatal density in leaves of sun, presence of abundant fibers in the vascular bundles of the central vein and presence of drusen. Therefore, it is concluded that the plant under study has a great acclimative capacity to the analyzed conditions (intense luminosity and periods of water deficit). |

A espécie Myrcia guianensis (Aubl.) DC., popularmente conhecida como mapirunga, ocorre em região de litoral no estado do Ceará e possui importância ecológica e potencial medicinal. Objetivou-se caracterizar a anatomia foliar ecológica dessa espécie nas estações de chuva e seca, bem como, ao sol e à sombra na Restinga cearense. Para isso, foram realizadas coletas no Jardim Botânico de São Gonçalo de folhas totalmente expandidas e fixadas em FAA70, sendo substituído por etanol 70% após 24 horas. Seguiu-se para os procedimentos anatômicos usuais no Laboratório de Ecologia da Universidade Estadual do Ceará, a fim de analisar qualitativamente e quantitativamente as estruturas da lâmina foliar, pecíolo e paradérmico. Como resultados obteve-se a presença de características que contribuem para sua sobrevivência em ambiente de Restinga com períodos de deficit hídrico e alta taxa de luminosidade, tais como: presença de cutícula levemente espessa, folha hipoestomática, aumento da densidade estomática em folhas de sol, presença de fibras abundantes nos feixes vasculares da nervura central e presença de drusas. Portanto, conclui-se que a planta em estudo possui grande capacidade aclimatativa às condições analisadas (intensa luminosidade e períodos de deficit hídrico).Universidade Federal de Santa Maria2020-06-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3099710.5902/1980509830997Ciência Florestal; Vol. 30 No. 2 (2020); 307-322Ciência Florestal; v. 30 n. 2 (2020); 307-3221980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/30997/30997Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessLemos, Viviane de Oliveira ThomazLucena, Eliseu Marlônio Pereira deBonilla, Oriel HerreraEdson-Chaves, BrunoFreitas, Morgana Andrade2021-05-20T04:00:45Zoai:ojs.pkp.sfu.ca:article/30997Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:45Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
