水稻（Oryza sativa L.）CV. Rupsail）种子合成蛋白质的能力随着种子活力的丧失而逐渐下降，核糖体后组分的损伤大于核糖体。精胺（0.4 mM）是多胺中提高蛋白质合成速率最有效的。也有迹象表明，氨酰-tRNA合成酶的损伤可能是老化种子蛋白质合成能力下降的原因之一。
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 mM) 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.
