Seeds should be stored properly in order to minimize the deterioration process. Therefore, the aim of this work was to evaluate the germination of Amburana cearensis seeds after storage in different packaging and environments. Seeds were stored in two packages (plastic and paper bags) under three different conditions: laboratory (30±5°C/66% RU); germination chamber (20±2°C/86% RU) and cold chamber (±10±2°C/77% RU) during 3, 6, 9 and 12 months. Seeds water content and germination were evaluated before and after the storage period. Seeds stored in germination chamber had higher values of water content either in plastic or paper bags. Physiological quality of A. cearensis seed was affected by the storage environment only when packed in paper bags, which showed 50% decreased germination as of 9 months in cold chamber.
