Polinização de Cambessedesia hilariana (Kunth) DC. (Melastomataceae): sucesso reprodutivo versus diversidade, comportamento e freqüência de visitas de abelhas

Abstract: -(Pollination of Cambessedesia hilariana (Kunth) DC. (Melastomataceae): reproductive success versus bee diversity, behaviour and frequency of visits). The reproductive phenology, pollination biology and reproductive system of Cambessedesia hilariana were studied in a population occurring on rocky outcrops at Vinhedo, São Paulo State, southeastern Brazil. This species presents a flowering peak between October and December with high daily flower production. Anthesis begins at 7:00 h with slow petal separation, f… Show more

“…2). This may be due to their vibration behavior, since smaller bees often collected from one anther at a time (Renner 1989;Fracasso & Sazima 2004). Furthermore, visits may last longer because less pollen was available because flowers of T. gracilis were intensively visited by B. pauloensis early in the day.…”

“…Na maioria das espécies de Melastomataceae, esse sistema reprodutivo é facilitado pela separação espacial entre o estigma e o pólen nas fl ores (hercogamia) e pela presença de anteras poricidas, que necessitam ser fortemente vibradas para liberação do pólen (Renner 1989). Entretanto, trabalhos recentes têm mostrado a presença de espécies autocompatíveis e apomíticas na família (Goldenberg & Shepherd 1998, Melo et al 1999, Goldenberg & Varassin 2001, Fracasso & Sazima 2004.…”

“…This genus is an important pollen source for oilcollecting bees due their capacity to remove pollen using vibration (Buchmann 1983). Other pollen sources with poricidal anthers as Senna and Cambessedesia species were also registered as important pollen sources for Centridini species (Fracasso and Sazima 2004;Dórea et al 2010;Gonçalves et al 2012).…”

“…The analysis was performed in R, using the Vegan package. The anther type and the flower's resources of each plant were determined according to literature (see Anderson 1979;Buchmann 1983;Oliveira et al 1987;Oliveira and Gibbs 1994;Kill et al 2000;Carvalho and Oliveira 2003;Fracasso and Sazima 2004;Pereira and Barbosa 2004;Andena et al 2005;Ragusa-Netto 2005;Souza and Lorenzi 2005;Del Lama and Peruquetti 2006;Filho et al 2007;Pool 2009). …”
