Biologia floral, melitofilia e influência de besouros Curculionidae no sucesso reprodutivo de Grobya amherstiae Lindl. (Orchidaceae: Cyrtopodiinae)

Abstract: -(Floral biology, melittophily and influence of curculionid beetles on the reproductive success of Grobya amherstiae Lindl. (Orchidaceae: Cyrtopodiinae)). The phenology, floral morphology, pollination mechanisms and reproductive biology of Grobya amherstiae Lindl. were studied in two populations located in altitudinal forests at Serra do Japi, Jundiaí, São Paulo State, Brazil. The flowering occurs in summer and lasts about one month (part of February and March). The flowers of an inflorescence open almost simu… Show more

“…However, spontaneous selfpollination tends to be avoided by the presence of special floral arrangements (Van der Pijl & Dodson 1966, Catling & Catling 1991. Manual pollination carried out under experimental conditions results in increased fruit production in many Orchidaceae species, if compared with populations in the natural environment (Pansarin 2003, Mickeliunas et al 2006, Storti et al 2011, Suetsugu 2015 influence the reproductive success in orchids' natural habitat.…”

“…Additionally, orchids tend to produce more viable seeds after cross-pollination (Stort 1983and 1986, Smidt et al 2006. Pollination carried out under experimental conditions also promotes increased fruit production in many Orchidaceae species, when compared with populations in the natural environment (Pansarin 2003, Mickeliunas et al 2006, Storti et al 2011. In their habitat, herbivory and fruit and seed predation can negatively influence its reproductive success.…”

“…Durante as observações às flores de C. micranthum, foi observado que opolinário geralmente é removido junto com o capuz da antera. A retenção do capuz da antera pelas polínias é um fenômeno conhecido e tem sido documentado para várias espécies de orquídeas como um mecanismo floral que tende a evitar a ocorrência de autopolinização (e.g., Catling & Catling 1991b;Singer & Cocucci 1999;Borba & Semir 2001;Mickeliunas et al 2006).…”

“…(e.g., Mickeliunas et al 2006;Pansarin et al 2006;Pansarin 2008;Pansarin & Amaral 2008). Estudos têm mostrado que orquídeas, cujas flores oferecem néctar como recurso apresentam maior sucesso reprodutivo em relação às espécies que produzem qualquer outro tipo de recurso ou são polinizadas por engano (Tremblay et al 2005).…”
