Pollination and breeding system in Adesmia bijuga Phil. (Fabaceae), a critically endangered species in Central Chile

Abstract: A. bijuga showed a mixed mating system that involves both cross-and self-pollination. The fruit set ranges from 20% to 60% in the absence or presence of pollinators, respectively. This selfing ability would provide reproductive assurance when pollinators fail. The taxon showed ability of asexual formation of seeds without the occurrence of fertilization by agamospermy. Supplemental outcross pollen did not increase female reproductive success, suggesting that the species is not pollen limited. All these factors… Show more

“…We analyzed the genetic diversity of the endangered Adesmia bijuga as a step for describing its biology and conservation status, complementing our previous studies (Hahn and Gómez 2008;Gómez et al 2012Gómez et al , 2014. We selected six polymorphic ISSR markers for analyzing 81 individuals, representing the only three remaining populations of this species in South America.…”

“…The exclusively South American genus Adesmia (Fabaceae) includes approximately 240 species of herbs and shrubs (Barreto-Dias et al 2004;Ulibarri and Burkart 2000). It has been widely studied because of its nutritional, pharmacological, agronomical and ecological importance (Barreto-Dias et al 2004;González et al 2004;Barboza et al 2009;Eyssartier et al 2009;Gómez et al 2013). In their natural range, Adesmia species are distributed in mountainous and semidesert areas, from Northern Peru to Patagonia and from the Andes range in Peru to the Serra do Mar in Brazil (Burkart 1967;Ulibarri and Burkart 2000;Mihoc et al 2006).…”

“…Adesmia bijuga es una especie arbustiva con alturas de hasta 3,5 m. En todo el mundo sólo existen tres poblaciones de la especie, las cuales se distribuyen en la Región del Maule en Chile central, con una superficie total aproximada de cuatro hectáreas. Dentro de las plantas vasculares que crecen en Chile esta especie se encuentra "En Peligro Crítico" debido a que su hábitat ha sido transformado por plantaciones forestales de especies exóticas (Gómez et al, 2012(Gómez et al, , 2014(Gómez et al, , 2016. Las poblaciones que hasta hoy han logrado sobrevivir se encuentran aisladas e integradas en un paisaje dominado por plantaciones de Pinus radiata D. Don (Gómez et al, 2014).…”
