Abstract: The aim of this study was to evaluate the physiological quality of babassu (Orbygnia phalerata Mart.) embryos in relation to drying rate. The fruits were kept in a dry chamber with forced air circulation at 57 ± 2°C and 37 ± 2°C for 0, 6 and 11 days. An interaction between the drying time and temperature on water loss was not observed. Fruits dried at 37 ± 2°C failed to achieve the same water content values as those dried at 57 ± 2°C. Embryos dehydrated at 37 ± 2°C remained viable even after 11 days of drying, while embryos dehydrated at 57 ± 2°C were dead after 6 days of drying. Germination percentages above 67% were obtained for all times at drying 37°C, even for seeds with 9% water content, which highlights a possible orthodox behavior. Under the experimental conditions of the present study, drying embryos at 57 ± 2°C decreased the percentage and speed of germination as well as the initial growth of seedlings.
