The capacity of rice ( Oryza sativa L. cv. Rupsail) seeds to synthesize protein shows a gradual decline with loss of seed viability, and the lesion in post‐ribosomal fraction is greater than that of ribosome. Spermine (0.4 m M ) is the most effective among the polyamines in enhancing the rate of protein synthesis. There are also indications that impairment of aminoacyl‐tRNA synthetase may be one of the causes for this decreasing ability in protein synthesis by aged seeds.
