The application of indolacetic acid, gibberellic acid and kinetin increased the germination pattern of Pinus pinea seeds. Nucleic acid metabolism during germination has been investigated. Seeds grown in the presence of all these substances, contained higher amounts of total nucleic acid than the controls. Kinetin was the most active factor, increasing t-RNA, DNA-RNA and r-RNA levels in embryos and megagametophytes. On the other hand, gibberellic acid showed in the first stages of germination a selective action on the DNA-RNA complex and afterwards on the r-RNA fraction. Indolacetic acid showed mainly a stimulating effect on DNA-RNA and r-RNA fractions embryos; no significant changes were observed in megagametophytes.
吲哚乙酸、赤霉素和激动素的施用提高了欧洲松种子的萌发模式。已对萌发过程中的核酸代谢进行了研究。在所有这些物质存在的情况下生长的种子，其总核酸含量高于对照。激动素是最活跃的因素，可增加胚和大配子体中t-RNA、DNA-RNA和r-RNA的水平。另一方面，赤霉素在萌发的第一阶段对DNA-RNA复合物表现出选择性作用，随后对r-RNA部分表现出选择性作用。吲哚乙酸主要对胚中的DNA-RNA和r-RNA部分有刺激作用；在大配子体中未观察到显著变化。
