Resumo: | (Orchidaceae of the State Park of Serra de Caldas Novas, Goiás State, Brazil). This study conducted a survey of the Orchidaceae species occurring at State Park of Serra de Caldas Novas (PESCAN) and a study of the floral biology and reproductive biology of Cyrtopodium eugenii Rchb. f. & Warm. and the effect of floral herbivory on reproductive success of this specie that occurs in the rocky fields of PESCAN. The Orchidaceae family consists of 850 genera, with about 20000 species, and has cosmopolitan distribution, but its greatest concentration is in the tropical region. In Brazil, 200 genera are found, with more than 2500 species, and then, it is considered the third country in the world in diversity of orchids, only inferior to Ecuador and Colombia. In the Cerrado Biome, the family is represented by 666 species, from these, 12 species and 7 genera were found in PESCAN. The most common habit among the species that occur in PESCAN is the terrestrial and the predominant flowering season is the rainy season. Only one specie flowers in the dry season, C. eugenii, a common specie in PESCAN, which flowers from May to September. Cyrtopodium eugenii flowers are pale-yellow with brown spots, but the lip is bright-yellow. The only species found as a pollinator of C. eugenii was Centris (Trachina) fuscata Lepeletier,1841 (Anthophoridae, Centridini). Although C. eugenii offers no floral rewards to pollinators, its lip seems to mimic flowers of Tetrapterys ramiflora A. Juss., a yellow-flowered oil producer Malpighiaceae. Thereby, C. eugenii deceives the pollinator. As in other species without reward, C. eugenii receives few visits from their pollinator, and consequently has a low fruit production rate. Cyrtopodium eugenii is self-compatible, but no fruit was generated by spontaneous self-pollination as well as agamospermy. Preliminary field observations revealed that inflorescences and flowers of C. eugenii experience continuous florivory. The natural florivory quantification shows that 55.20% of the flowers weren t eaten,while in 15.45% sexual structures were eaten (florivory direct effect). More flowers had the lip damaged (20.50%) than the other petals and sepals (18.92%). A manipulative experiment showed a significant decrease in C. eugenii reproductive success (male and female), only if the florivory occurred in the lip (florivory indirect effects). This result indicates that the lip is the most important flower part to attract the pollinator and to C. eugenii reproduction, because even with a high level of herbivory in the other petals and sepals, the reproductive success didn t decay significantly. |

Neste estudo foi realizado um levantamento das espécies de Orchidaceae ocorrentes no Parque Estadual da Serra de Caldas Novas (PESCAN), bem como um estudo da biologia floral e reprodutiva de Cyrtopodium eugenii Rchb. f. & Warm. e o efeito da herbivoria floral sobre o sucesso reprodutivo desta espécie que ocorre nos campos rupestres do PESCAN. A família Orchidaceae, constituída por 850 gêneros, com cerca de 20.000 espécies, apresenta distribuição cosmopolita, mas com maior concentração na região tropical. No Brasil, são encontrados 200 gêneros, com mais de 2.500 espécies, sendo considerado o terceiro país do mundo em diversidade, perdendo apenas para Equador e Colômbia. No Bioma Cerrado, a família é representada por 666 espécies, sendo que no PESCAN foram encontradas 12 destas espécies, distribuídas em sete gêneros. O hábito mais comum entre as espécies ocorrentes no PESCAN é o terrestre e a época de floração predominante é na estação chuvosa. Apenas uma espécie floresce na estação seca, C. eugenii, uma espécie muito comum no PESCAN, florescendo entre os meses de maio e setembro. As flores de C. eugenii são amarelo-pálidas com máculas castanhas, porém o labelo é amarelo-vivo. A única espécie, encontrada neste estudo como polinizador de C. eugenii foi Centris (Trachina) fuscata Lepeletier,1841 (Anthophoridae, Centridini). Apesar de C. eugenii não oferecer recompensa floral ao seu polinizador, seu labelo parece mimetizar a flor de Tetrapterys ramiflora A. Juss. uma espécie de Malpighiaceae de flor amarela, produtora de óleo, enganando assim o polinizador. Assim como em outras espécies sem recompensa, C. eugenii recebe poucas visitas de seu polinizador, e consequentemente, possui baixa taxa de produção de frutos. Cyrtopodium eugenii é auto-compatível, porém não foram gerados frutos por auto-polinização espontânea, assim como por agamospermia. Observações preliminares realizadas no campo revelaram que as inflorescências e flores de C. eugenii sofrem constante florivoria ou herbivoria floral. A quantificação desta herbivoria natural mostrou que 55,20% das flores não sofreram herbivoria enquanto 15,45% foram inutilizadas pelo consumo das estruturas sexuais (efeitos diretos da florivoria). Foram encontradas mais flores com herbivoria no labelo (20,50%) do que com herbivoria em outros verticilos (18,92%). Um experimento manipulativo mostrou que há uma diminuição significativa no sucesso reprodutivo (masculino e feminino) de C. eugenii apenas quando a herbivoria ocorre no labelo (efeitos indiretos da florivoria). Esse resultado indica que o labelo é a parte da flor mais importante na atração do polinizador e para a reprodução de C. eugenii, pois apesar de um alto nível de herbivoria nos outros verticilos ter sido aplicada, não houve diminuição significativa no sucesso feminino e masculino dos indivíduosMade available in DSpace on 2014-07-29T16:21:20Z (GMT).
