Resumo: | Post-fi re phenological behavior and breeding biology of the Spiranthera odoratissima A. St.-Hil. (Rutaceae). The phenological behavior of species in response to cerrado stricken by fi re is little known. A phenological and reproductive biological study of Spiranthera odoratissima was carried out in an anthropized area of cerrado sensu stricto affected by fi re in Goiânia County, Goiás, Brazil. Phenolocial observations indicated that the indivi- duals bloomed in synchrony three months after the fi re. The phenological rhythms were associated with the seasonal pluviometric effects, a chara- cteristic pattern of shrublet species of the cerrado. The fl owers are white with a sweet odor and are grouped in panicle infl orescences. The blos- soming occurs during dusk and begins at around 16h. It offers pollen and nectar to its visitors. The species produces 32.8?l (± 3.4) of nectar with an average concentration of 16.4% (± 0.43) in equivalents of sucrose. The pollination system (phalenophily) was proposed based on an analysis of the fl ower’s characteristics. Observed visitors were bees (Apis to be merely resource thieves. It was observed that Trigona spinipes Fabr. can act as a secondary pollinator during the pilling of pollen. The results of manual pollination and the incompatibility index (ISI) indicate that the species is xenogamous and self-compatible. |

O estudo da fenologia e biologia reprodutiva de Spiranthera odoratissima A. St.-Hil. foi realizado em uma área antropizada de cerrado sensu stricto submetida ao fogo no município de Goiânia, Goiás. Observações fenológicas evidenciaram que os indivíduos floresceram sincronicamente três meses após a queima. Os ritmos fenológicos estiveram associados aos efeitos da sazonalidade pluviométrica, padrão característico das espécies subarbustivas de cerrado. As flores são brancas, de odor adocicado e estão reunidas em inflorescências paniculadas. A antese é crepuscular e inicia-se por volta das 16h. Os recursos oferecidos aos visitantes são pólen e néctar. A espécie produz 32,8?l (± 3,4) de néctar com concentração média de 16,4% (± 0,43) em equivalentes de sacarose. O sistema de polinização (falenofi lia) foi proposto com base na análise das características florais. Os visitantes observados foram abelhas (Apis mellifera Linnaeus), moscas, vespas, formigas e besouros, porém, devido ao comportamento na inflorescência, foram considerados apenas pilhadores de recursos. Foi constatado que Trigona spinipes Fabr. pode atuar como polinizador secundário durante a pilhagem de pólen. Os resultados das polinizações manuais e o índice de incompatibilidade (ISI) indicam que a espécie é xenógama e auto-compatível.Universidade Federal de Santa Catarina2011-09-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2008v21n1p2910.5007/2175-7925.2008v21n1p29Biotemas; v. 21 n. 1 (2008); 29-392175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2008v21n1p29/18966Copyright (c) 2008 Cristiane Soares Pereira da Silva, Mirley Luciene dos Santosinfo:eu-repo/semantics/openAccessSilva, Cristiane Soares Pereira daSantos, Mirley Luciene dos2018-03-07T18:16:27Zoai:periodicos.ufsc.br:article/20961Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2018-03-07T18:16:27Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
