The seeds were sealed in polythene bags and stored at 25 ± 1 °C for 3, 6, 9, 12 and 18 months. In both the cultivars, germinability decreased whereas membrane deterioration assayed as electrical conductivity of the seed leachates increased with storage period. The decrease in germinability was well correlated with increased accumulation of H<sub>2</sub>O<sub>2</sub> and malondialdehyde content. The activities of peroxidase, catalase, ascorbate peroxidase, glutathione reductase and superoxide dismutase decreased with ageing. Seeds of cv. H1098 were more susceptible to ageing than HS6.
