Abstract
Seeds of the tropical tree Antiaris toxicaria have typical recalcitrant storage behaviour. The purpose of this work was to examine the effects of temperature and moisture content (MC) on germination during storage. Germination of seeds with a MC of 1.14, 0.90, 0.76 or 0.68 g H2O g(-1) DW was not significantly reduced when stored at 15 degrees C for one year. However, seeds with a MC of 0.90 or 0.68 g g(-1) DW stored at -20 degrees C for one month lost viability, as did approximately 50% of those at 4 degrees C. After one year, seeds with a MC of 0.90 g g(-1) DW stored at 15 degrees C had significantly higher germination percentage than those stored at -20, 4, 10 and 25 degrees C; seeds with a MC of 0.68 g g(-1) DW stored at 25 degrees C had significantly higher germination percentage than those stored at -20, 4, 10 and 15 degrees C. Thus, the lower the MC (0.68 g g(-1) DW) of seeds, the higher the storage temperature (25 degrees C) required to ensure seed survival.
