The moringa (Moringa oleifera Lam.) recently introduced into the department of Córdoba - Colombia, is planted for fodder, food and human medicine. Seeds are stored in different types of containers under oscillatory conditions of temperature and relative humidity, influencing germination, vigor and seedling quality. The objective was to evaluate the physiological seed quality in different types of packaging in both controlled environments and the local environment during a year of storage. The experimental design was completely randomized with five treatments. i) in a refrigerator and aluminum container 7°C and 77.0% relative humidity (RH), ii) in a refrigerator and plastic container 7°C and 77.0% RH, iii) in cold room and aluminum container 6°C and 70% RH, iv) cold room and plastic container 6°C and 70% RH, v) without refrigeration in glass container at average temperature of 28°C and HR average of 74%. Seeds of regional grown trees were used. Monthly physiological quality based on the percentage of germination, germination rate index, moisture content, seedling height and number of leaflets was evaluated. Moringa seeds stored under ambient conditions of the Sinú valley loses its physiological quality in 150 days, due to the effects of high temperature and humidity fluctuations that cause deterioration. The storage under refrigeration, in plastic or aluminum packaging, allows to preserve its physiological potential for up to 360 days.

Keywords : Vigor; deterioration; germination; moisture; seedling height.
