本文以高羊茅（Camarillo品种）种子为材料，采用人工加速老化的方法，对其老化过程中的RNA和PolyA+RNA进行研究。结果表明，随着老化种子发芽率的下降，干种子胚中的RNA、PolyA+RNA含量均随之下降。在严重老化的种子中，则丧失其在发芽过程中新RNA、PolyA+RNA的合成能力。同时大分子量的RNA降解为小分子量的RNA并丧失其完整性。研究结果表明，在高羊茅种子人工加速老化的过程中，PolyA+RNA含量比总量RNA对老化种子发芽率的下降起着更多的作用。
In this paper, seeds of tall fescue (Camarillo variety) were used as material to study the aging process of RNA and PolyA + RNA by artificial accelerated aging method. The results showed that the content of RNA and PolyA + RNA in dried seed embryos decreased with the decrease of germination percentage of aged seeds. In severely aged seeds, they lost the ability to synthesize new RNA, PolyA + RNA, during germination. At the same time, the large molecular weight RNA degrades to small molecular weight RNA and loses its integrity. The results showed that the content of PolyA + RNA had more effect on the germination rate of aged seeds than the total amount of RNA during artificial accelerated aging of tall fescue seeds.
