In the present study, the seeds of bitter gourd ( Momordica charantia L. ) cultivar Blue Mountain Giant White were hydrated, but re-dried under different desiccation rates. The effects of desiccation rate on antioxidative responses during hydration and re-drying, and the quality of treated seeds were examined. The results indicated that both the levels of antioxidants and the activities of antioxidative enzymes were increased during hydration. More antioxidants were accumulated and highter activities of antioxidative enzymes ( SOD, CAT, APX ) were maintained for slow-drying seeds during re-drying, as compared to that of fast-drying seeds. The seeds subjected to slow-drying had greater emergence percentage and faster emergence rate than fast-drying seeds.
