Resumo

ABSTRACT This paper aimed to evaluate the effect of packaging, environments, and storage periods on physiological quality of Talisia esculenta (A. St. Hil.) Radlk seeds. Seeds were conditioned in PET transparent bottle, Kraft paper bag, and transparent polyethylene bag; they were stored in chamber (18 °C; 50% RH), in freezer (-21 ± 2 °C; 95% RH), and under laboratory natural environment (28 ± 5 °C; 65% RH). They were evaluated at the 0, 25th, 50th, 75th, and 100th storage day for moisture content, thousand seed weight, emergence percentage, emergence rate index, length, and dry mass of shoot and root. T. esculenta seeds should be stored in chamber or laboratory natural environment, packed in polythene bag up to 25 days. The Kraft paper bag and the PET bottle cannot be used for storing T. esculenta seeds. Freezer is not recommended for storing T. esculenta seeds because it makes them unviable.
