Acompanhamento de fenofases da Erythrina crista-galli (L.) nas condições do Município de São Gabriel

Abstract

The Erythrina crista-galli (L.), known for cockpur belonging to the family Fabaceae is a species characteristic of the southern fields present in riparian forests and wetlands. The species is so widely used ornamental trees in city squares, and is still suitable for reclamation for the character of a pioneer, and adapt to environments with lower humidity. Very few studies related to the phenology and reproduction of the species are found in the literature and is still great difficulty in collecting seed for reproduction. Thus the study aims to characterize the vegetative and reproductive phenological phases of the species in the vicinity of São Gabriel - RS for which have concrete data to obtain seeds of this species. Were followed from October 2010 to April 2011 30 individuals of the species along the BR 290, photographing and records on both clones of all individuals. Characterized the first sequence of both clones in the period from October to December 2010 as the highest intensity, registering the reproductive phases of flowering and fruiting. In the second period from March to April, with lower intensity was observed only 20% of individuals had only one flowering and (a) individual in the fruiting stage. Finally, we characterized the months of November and December as the highest percentage of flowering and fruiting is an indication that time to collect seeds of Erythrina crista-galli (L.) in the region of São Gabriel - RS.
