Biologia reprodutiva de Byrsonima gardnerana A. Juss. (Malpighiaceae) e interações com abelhas Centris (Centridini) no nordeste do Brasil

Abstract: -(Reproductive biology of Byrsonima gardnerana A. Juss. (Malpighiaceae) and interactions with Centris bees (Centridini) in northeastern Brazil). The pollination ecology, the reproductive system and the flowering phenology of Byrsonima gardnerana A. Juss were studied in a Caatinga area of the Parque Nacional do Catimbau, Pernambuco state, Brazil. The species is a shrub with hermaphrodite and zygomorphic flowers, which change color after pollination, with oil as primary floral resource. Flowering pattern is annu… Show more

“…Juss., B. crassifolia e B. coccolobifolia (Benezar & Pessoni 2006, Costa et al 2006, Rêgo & Albuquerque 2006, Bezerra et al 2009), sendo importante no efeito de atração das abelhas. A mudança na coloração floral evoluiu, de acordo com Weiss (1995), provavelmente em resposta à seleção por polinizadores e reflete uma convergência funcional dentro das angiospermas.…”

“…possui 160 espécies, com cerca de 70 no Brasil (Flinte et al 2003), onde são importantes componentes da flora do cerrado (Barros 1992). Por possuírem flores vistosas, frutos que atraem aves e pelo seu rápido crescimento, espécies de Byrsonima têm grande potencial ornamental e na recuperação de áreas degradadas (Anderson 1981 Em relação ao sistema reprodutivo, auto-incompatibilidade foi constatada em B. gardnerana (Bezerra et al 2009), B. crassifolia (Rêgo & Albuquerque 1989) e B. sericea (Teixeira & Machado 2000;Costa et al 2006). Barros (1992) observou certo grau de autocompatibilidade nas sete espécies de Byrsonima estudadas.…”

“…Its flower offers pollen and oil as rewards to floral visitors, and other features such as diurnal anthesis, yellow flowers, exposed reproductive structures and floral architeture to favor landing, suggest the melitophily syndrome (Faegri and Van De Pijl 1979). Concentrated flowering, gradual and asynchronous availability of mature flowers and their different orientations in the inflorescence arrangement which facilitate the access to flower visitors, as observed in B. cydoniifolia, seem to be common characteristics to many species of the genus Byrsonima which rely on bee pollination, as reported by many authors (Barros 1992, Pereira and Freitas 2002, Teixeira and Machado 2000, Benezar and Pessoni 2006, Smith et al 2006, Rêgo and Albuquerque 2006, Bezerra et al 2009). In fact, B. cydoniifolia was visited by a range of floral visitors, all of them belonging to two bee Families.…”

“…Floral visitors were also classified according to the size as being medium to large (body length ≥ 12 mm) or small (body length < 12 mm) (Bezerra et al 2009). Later, floral visitors were placed in the zoological collection of the Universidade Federal de Mato Grosso do Sul.…”
