This study aimed to evaluate the viability of catanduva seeds stored for 210 days under controlled and uncontrolled environmental conditions (laboratory), in plastic, paper and glass packaging. The experimental design was completely randomized in a sub-subdivided plot, where the main plot were the storage conditions (laboratory and cold room) and sub-plots consisted of the packaging (plastic and paper bags and glass bottles) and sub-sub-plots of the storage times(0, 30, 60, 90, 120, 150, 180 and 210 days). The tests were conducted in the laboratory and greenhouse. Evaluations were made every 30 days of the percentage of germination and the rate of germination velocity in the laboratory and of seedling emergence in the greenhouse. The seed viability of catanduva decreased as a function of storage time during the 210 days. Catanduva seeds (Piptadenia moniliformis Benth.) can be packed for 210 days either in glass bottles or plastic bags without losing their physiological potential. The controlled environment (18-20 °C, ±60% RH) is the most suitable. Source
