The effects of storage time and exogenous gibberellic acid on lychee seeds germination were studied. The seeds were removed from ripe fruits, washed, dried, stored at 8°C for 0, 15 and 30 days, and soaked during 24 hours in water and GA3 at 50, 100 and 200 mg.L-1 solutions. As the storage period increased, the germination capacity was lost, and the seeds had a short germinability after 30-day storage period. Gibberellic acid had not significant effect on enhancing both the germination percentage and rate.
