GERMINAÇÃO E VIGOR DE SEMENTES DE Inga laurina (Sw.) Willd. EM FUNÇÃO DA MATURAÇÃO E DO ARMAZENAMENTO DOS FRUTOS

Abstract

The Inga laurina (Rich.) Willd, is a fruit cultivated for reforestation, shade and food has recalcitrant seeds. This study aimed to evaluate the germination and vigor of seeds as a function of maturation and fruit postharvest storage. The experiment was carried in the Laboratório de Análise de Sementes do Centro de Ciências Agrárias, in Areia, PB, Brazil. The evaluation of treatments effects was accomplished by determining the water content, germination, emergence and vigor tests. To maturation accompanying nine harvests were performed, in which determined the dimensions and water content of fruits and seeds, as well as germination and vigor. Were used for storage periods of 0, 24, 48, 72, 96, 120, 144 and 168 hours in a laboratory environment (temperature of 28.5 °C and 75% of relative humidity) and evaluated the water content, germination and vigor. The physiological maturation of I. laurina seeds in Areia, PB conditions occurs at 139 days after flowering and harvest point is reached between 146-160 days. Seeds of I. laurina maintains its viability when stored in fruit in laboratory environment throughout the storage period.
