FLORAL BIOLOGY OF Syagrus oleracea cf (Mart.) Becc IN BARIRI PARK, PARA MINAS CITY, MG, BRAZIL

Abstract

S. oleraceais a species belonging to the family Arecaceae, is popularly known as guariroba and originally from Brazil.It is located in the tropics, lying naturally composing the vegetation of forests in several states, such as Goiás, Minas Gerais, MatoGrosso do Sul, MatoGrosso, Bahia, São Paulo, Rio de Janeiro, Espirito Santo and Paraná.Pollination is the process by which male reproductive cells of higher plants (pollen grains) produced in the anthers of flowers, are transferred to the female recipient (stigma) of the same plant or plant of the same species.Through this process, the pollen sowing the flower stigma, beginning the formation of the pollen tube, which will culminate with the fertilization of the egg cell.Thus the study of floral biology of this species and other justified by the importance of this process in reproductive propagation of species.Excessive use of pesticides in agriculture has led to numerous endangered pollinators become the pollen grain process for unviable egg cell, which may jeopardize the survival of many species. This work aims to study the reproductive biology of the species Syagrus oleracea cf and its floral morphology in order to provide a basis for understanding the pollination process of this species. Its main objectives Identify potential pollinators of S. oleracea; Determine schedules and frequency of pollinator species visitation; Featuring floral, external and internal morphology of S. oleracea; Determine the presence of relevant substances and structures to their relationship to pollinators.
