Qualidade fisiológica de sementes de Enterolobium contortisiliquum armazenadas em diferentes embalagens e temperaturas

Abstract

The study aims to evaluate the quality of Enterolobium contortisiliquum’s seeds stored in different environments and packaging. The treatments tested were lots of E. contortisiliquum seeds stored for four years and six months in plastic bags and glass jars stored in both cold and wet room 70% and glass bottles kept in a cold chamber at -5 ° C. Four replications were used containing twenty-five seeds each. It was determined the moisture content (for treatments in a humid chamber), and the physiological quality was analyzed from: germination percentage, germination speed index and electrical conductivity test, the latter only for treatments in a humid chamber. It was concluded that the Enterolobium contortisiliquum seeds are orthodox and maintain their germination potential in these storage time. The seeds of Enterolobium contortisiliquum, have greater conservation of physiological quality when stored in a cold environment (-5 ° C) and dry. The electrical conductivity test has proved to be an efficient method for evaluation of the physiological quality of the batch of seeds Enterolobium contortisiliquum.
