Changes in seed quality during seed development in contrasting crops.

The hypothesis that seeds attain maximum quality at the end of the seed-filling phase (termed mass maturity) and that thereafter seed viability and vigour decline has been widely accepted. In studies with cereals and vegetable crops, however, maximum potential longevity was not attained by developing seed crops until some time after mass maturity. In the cereals, seed quality declined after the maximum had been achieved, this decline being quantitatively similiar to that expected in postharvest air-dry storage. In capsicums and tomatoes, however, no substantial decline in seed quality was detected after maximum quality had been attained. This difference between the two crop groups is compatible with results of postharvest seed storage longevity at air-dry and very high moisture contents.
