Hydration effect on lipid peroxidation and peroxide-scavenging enzymes activity of artificially aged peanut seed

Abstract

Hydratation offers an effective means for raising seed performance in many crop species. The objective of this study was to evaluate the effect of vermiculite hydration on germinability, seedling growth, and several physiological activities related to vigour in the artificially aged seed of two peanut cultivars. Hydration was achieved by mixing the unaged and aged seeds with moist vermiculite No.3 at 15 o C for 48h. The partially hydrated seeds were air-dried at 25 o C for 72h to their original moisture level (6.2%). Significant differences existed between unaged and aged seeds for germination percentage, mean germination time and seedling growth
