Taxas de cruzamento em uma população natural de Cryptocarya Moschata Nees (Lauraceae)

Abstract: -[Outcrossing rates of a natural population of Cryptocarya moschata Nees (Lauraceae)]. The mating system of the canopy Brazilian Atlantic rain forest tree Cryptocarya moschata was studied at Parque Estadual Carlos Botelho, São Miguel Arcanjo, São Paulo, Brazil. Outcrossing rates were determined through electrophoretic allozyme markers from seedlings germinated of seed cohorts collected from 35 trees. An indirect estimate of the outcrossing rate at equilibrium gave a mean of eq t = 0.51.

“…this pattern has been reported also in previous studies using RaPDs in tropical tree species (Cardoso et al, 1998;Pither et al, 2003). High variability in the tropical species of the lauraceae family has been associated with its dioeciousness, protogyny, insect pollination and animal-mediated seed dispersal (gibson & Wheelwright, 1995;moraes & monteiro, 2002), although low RaPD variability was recently reported in an endangered woody non-tropical lauraceae species (ZhongSheng et al, 2005).…”

“…the species appears to have an allogamous mating system, which is common in other lauraceae species (gibson & Wheelwright, 1995;moraes & monteiro, 2002). it is insect pollinated, with meliponinae bees apparently most important (Kubitzki & Kurz, 1984) and, possibly, small thysanoptera insects (Spironello et al, 2003;W.…”

“…Although there is no consensus on the predominant mating system for Rosewood, the rate of outcrossing is suspected to be high and similar to other Lauraceae species (Gibson et al, 1996;Moraes & Monteiro, 2002). This could further explain the high levels of genetic diversity found in this current study.…”
