摘要

The pattern of ageing was compared under both natural and accelerated ageing conditions in two soybean cultivars and the loss of viability and different vigour parameters viz., seedling dry weight, vigour index I, release of volatile aldehydes and loss of membrane permeability were studied. All the vigour and viability parameters showed a continuous decline under both natural and accelerated ageing conditions with increased time period, but the nature of decline was different under these two ageing conditions. Significant difference was observed between the varieties under both ambient and accelerated ageing conditions for all the parameters except for seedling dry weight under ambient storage and electrical conductivity under accelerated ageing conditions. Even though a general decline was observed in different vigour and viability parameters under both ambient and accelerated ageing conditions. The overall pattern of ageing was different under these two situations concluding that the accelerated ageing did not exactly represent the natural ageing particularly for short duration of storage of one year.
