It contains a mosaic of vegetation types and various taxonomic and ecological studies are exploring the previously almost unknown flora. This study is a floristic survey of the species of the families Clusiaceae s.s., Calophyllaceae and Hypericaceae in the PNV and an investigation of the floral biology and visitors and potential pollinators of Clusia nitida Bittrich, ined. (Clusiaceae s.s.). The field work was conducted between November 2009 and January 2011. Collections of fertile individuals were made in different vegetation types and collections of Clusia nitida were made so that we could establish the flowering phenology and make visual observations and experiments to determine the breeding system and floral visitors of C. nitida.In the PNV, "Clusiaceae s.l." is represented by 7 genera and 17 species: Calophyllum (1), Caraipa (2), Clusia (6), Platonia (1), Symphonia (1), Tovomita (2) and Vismia (4), occurring in all environments of the park. Six new records are made for Roraima and there is the possibility of a new species of Vismia, which requires more complete fertile material before confirmation. We present identification keys, taxonomic descriptions, photographic illustrations and document the occurrence of species in the PNV and elsewhere, thus contributing to the information about the family in Amazonia. The flowering season of the species is from September to February and the fruit formation is from November to July. The sex ratio between staminate and pistillate and staminate individuals is 2:1, respectively. The anthesis and floral resin secretion occur first in the staminate flowers and coincides with the beginning of the activities of the floral visitors. Clusia nitida is a non-apomictic species. The reproductive success was greater in the hand-pollination treatment, showing the importance of a vector to carry the pollen from the staminate to the pistillate flower. Clusia nitida was visited by eight species of bees and the main pollinators were Trigona spp. Taxonomic studies like this and studies of floral biology are very important so that we can reduce the scarcity of basic, reliable data in the Amazon. O Parque Nacional do Viruá (PNV) é indicado como um lugar de alta biodiversidade, formando o que é conhecido como um mosaico de vegetações e é alvo de vários estudos taxonômicos e ecológicos para conhecer a flora previamente quase desconhecida. O presente estudo realiza o levantamento florístico das espécies das famílias Clusiaceae s.s., Calophyllaceae e Hypericaceae no PNV e investiga a biologia floral e os visitantes e possíveis polinizadores de Clusia nitida Bittrich, ined. (Clusiaceae s.s.). O trabalho de campo foi realizado entre novembro de 2009 e janeiro de 2011. Coletas de indivíduos férteis nos diferentes tipos de vegetação foram realizadas, bem como coletas de Clusia nitida para estabelecer a fenologia da floração e observações visuais e experimentos foram realizados para determinar o sistema reprodutivo e os visitantes florais da espécie. No PNV, ―Clusiaceae s.l. está representada por 7 gêneros e 17 espécies: Calophyllum (1), Caraipa (2), Clusia (6), Platonia (1), Symphonia (1), Tovomita (2) e Vismia (4) e ocorrem em todos os ambientes do PNV. Seis novos registros para o Estado de Roraima são feitos e existe a possibilidade de uma espécie nova de Vismia, sendo necessário material fértil mais completo para essa confirmação. Apresentamos chaves de identificação, descrições taxonômicas, ilustrações fotográficas e ocorrência das espécies no PNV e outros locais, colaborando, portanto, com o aumento de informações mais claras sobre as Clusiaceae na Amazônia. Clusia nitida floresce de setembro a fevereiro e forma frutos de novembro a julho. A razão sexual entre indivíduos estaminados e pistilados é de 2:1, respectivamente. A antese e secreção da resina floral ocorrem primeiro nas flores estaminadas e coincide com o horário de início das atividades dos visitantes florais. Clusia nitida é uma espécie não-apomítica. A maior formação de frutos houve no tratamento de polinização manual, mostrando a importância de um vetor para realizar o transporte do pólen da flor estaminada para a pistilada. Clusia nitida foi visitada por 8 espécies de abelhas, sendo os principais polinizadores as Trigona spp. É de fundamental importância a continuidade de estudos taxonômicos e de biologia reprodutiva para que se possa diminuir a escassez de dados básicos e confiáveis na região Amazônica. 2020-02-18T19:41:53Z 2020-02-18T19:41:53Z 2011-07-07 Dissertação https://repositorio.inpa.gov.br/handle/1/12728 http://lattes.cnpq.br/1440396954810002 por Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Instituto Nacional de Pesquisas da Amazônia - INPA Botânica
