  • Abstract
    Maize (Zea mays L.) seeds were subjected to accelerated aging treatment for, 3, 7, and 14 days at 45 ±1 C° and 100% relative humidity. These artificially aged seeds were compared to control (Unaged seeds) for evaluation of vigor in seeds. Accelerated aging of Maize seeds up to three days had significant effect on germination percentage solute leakage. However, further increase in aging period caused an increased in solute leakage and a decrease in germination percentage. Germinability was lost completely at 14 days of accelerated aging. In addition, the reduction in germination percentage was correlated with decrease in seedling length, germination speed index, seed vigor index, seedling fresh dry weight. Finally, the results revealed that accelerated aging caused depression of maize seeds viability through the above parameters.
