Biodiversidade das Myrtaceae Brasileiras Adaptadas a Florida, EUA (Biodiversity of Brazilians Myrtace ae Adapted to Florida, USA)
A America e em especial o Brasil, sao ricos em especies frutiferas tropicais nativas e/ou exoticas de grande potencial fitoquimico. Neste contexto, podemos destacar as especies da familia Myrtaceae que apresentam elevado potencial de uso pela presenca de compostos, principalmente de natureza fenolica em suas folhas e frutos. Diante disso, a presente pesquisa objetivou catalogar a biodiversidade das Myrtaceae brasileiras adaptadas a Florida, EUA. Foram feitas duas visitas de cinco dias cada junto as colecoes pertencentes a instituicoes publicas e privadas no Estado da Florida, EUA. A primeira a fim de catalogar as Myrtaceae brasileiras existentes e a segunda para observar as alteracoes fenologicas. Para a realizacao da fenologia observou se os padroes de enfolhamento, floracao e frutificacao. As plantas tambem foram classificadas quanto ao tipo. Os resultados indicaram que existem alteracoes fenologicas entre a duas observacoes realizadas nas especies brasileiras, com surgimento de flores e/ou frutos. Conclui se que nas colecoes pertencentes a instituicoes publicas e privadas no Estado da Florida, EUA, existem 64 Myrtaceae e destas 16 sao de origem brasileira, as quais estao totalmente adaptadas ao novo ecossistema: Acca sellowiana (O.Berg) Burret, Eugenia brasiliensis Lam. Eugenia cerasiflora Miq. Eugenia luschnathiana (O.Berg) Klotzsch ex B.D.Jacks. Eugenia pyriformis Cambess. Eugenia stipitata McVaugh, Eugenia uniflora L. Myrciaria dubia (Kunth) McVaugh, Myrciaria floribunda (H.West ex Willd. O.Berg, Myrciaria glomerata O.Berg, Plinia cauliflora (Mart. Kausel, Plinia edulis (Vell. Sobral, Psidium acutangulum DC. Psidium cattleianum Sabine, Psidium guajava L. e Psidium guineense Sw. Biodiversity of Brazilians Myrtaceae Adapted to Florida, USA A B S T R A C T America and especially Brazil, are rich in tropical fruit species native and/or exotic big phytochemical potential. In this context, we highlight the species of Myrtaceae family that have high potential for use by the presence of compounds, mainly phenolic nature in its leaves and fruits. Therefore, the present study aimed to describe the biodiversity of Brazilians Myrtaceae adapted to Florida. Two visits five days each were made along the collections belonging to public and private institutions in the State of Florida, USA. The first to catalog existing Brazilians Myrtaceae and second to observe phenological changes. To perform the phenology observed patterns of foliage, flowering and fruiting. Plants were also classified according to type. The results indicated that there are phenological changes between the two observations carried out in Brazilian species, with the emergence of flowers and/or fruits. We conclude that the collections belonging to public and private institutions in the State of Florida, there are 64 Myrtaceae and these 16 are from Brazil, which are fully adapted to the new ecosystem: Acca sellowiana (O.Berg) Burret, Eugenia brasiliensis Lam. Eugenia cerasiflora Miq. Eugenia luschnathiana (O.Berg) Klotzsch ex B.D.Jacks. Eugenia pyriformis Cambess. Eugenia stipitata McVaugh, Eugenia uniflora L. Myrciaria dubia (Kunth) McVaugh, Myrciaria floribunda (H.West ex Willd. O.Berg, Myrciaria glomerata O.Berg, Plinia cauliflora (Mart. Kausel, Plinia edulis (Vell. Sobral, Psidium acutangulum DC. Psidium cattleianum Sabine, Psidium guajava L. and Psidium guineense Sw. Keywords: Native fruits, Flora of Brazil, Phenology, Botanical Garden.
