Effects of drying and storage conditions in the quality of sunflower seeds

Resumo

The viability of seeds passing through the appropriate conditions of harvest and post -harvest storage and the step. The objective of this study was to evaluate the physiological potential of sunflower seeds under different storage conditions (25 °C and 50%, 20 °C and 60%, 30 °C and 40% RH air) using different packages (permeable and impermeable). Physiological assessments were carried seeds in zero, three and six months of storage times and analyzed by the average test were compared by Tukey test at 5% probability. Under the conditions of 20 °C and 60% RH, and 25 °C and 50% RH in air and impermeable packaging obtained the best quality results. The physiological potential of sunflower seeds was affected by drying temperatures and storage conditions. The drying air temperature above 45 °C negatively affected the quality of sunflower seeds. Permeable and waterproof packaging not guaranteed the quality of sunflower seeds during storage. The quality of sunflower seeds stored up time of three months was negatively affected. The conditions of 20 °C and 60% RH air were more favorable for the preservation of physiological quality of sunflower seed during the storage time.
