Abstract

This experiment was conducted to examine the effect of pre-storage seed priming on biochemical changes in okra seed. Two factorial complete randomize design with three repeats was used for this experiment. Seeds were primed with water, polyethylene glycol 8000 (PEG-8000) and Mannitol solutions while dry seeds were used as control. After treatment seeds were dried to initial moisture content and then evaluated at zero, 3 and 6 months storage for lipids, aldehydes and electrical conductivity. Results showed that reduction in lipids content and increase in aldehydes and electrical conductivity occurred during storage for each treatment but it was significantly controlled by priming with PEG at -1.2 Mpa water potential for eighteen hour duration followed by priming with Mannitol at the same water potential and duration as used for PEG priming compared to water treatment and dry seeds.
