STYLAR MOVEMENT IN Talinum fruticosum (TALINACEAE): CONTRIBUTIONS TO THE REPRODUCTIVE SUCCESS OF THE SPECIES IN POPULATIONS FROM CENTRAL-WEST BRAZIL

In plant species, the movement of reproductive structures can be an adaptive advantage in mating system studies. This phenomenon promote outcrossing or cause a reduction intrafloral male-female sexual interference. Consequently, this contributes to avoidance self-pollination and/or delayed autonomous self-pollination. The aim short communication is report results assessments done two natural populations native species from central-west Brazil that grows spontaneously and sub-spontaneously opening ruderal areas Pantanal. study, stigma was recorded throughout floral anthesis, determined. Floral measurements such as: flower time, pollen viability period receptive were also reported. formation fruits by spontaneous cross-pollination reinforces hypothesis stylar Talinum fruticosum facilitate hinder some situations.
