在海洋松树针叶，基础设施和生化结果的比较表明，一个优先网站的合成单萜烃（C10）位于上皮细胞的树脂导管，具有较高的单萜含量比上部的针的基部。14C在基部的单萜中的掺入分别比在中部和上部重要16倍和66倍。对树脂道上皮细胞演化的电镜研究表明，这些细胞具有暂时的活性，这种活性仅在针叶基部非常强烈，而倍半萜（C15）则在整个针叶中按照永久的过程合成。针叶的三个部分呈现出渐进的、连续的积累过程，并且14CO2以倍半萜的形式被显著地掺入。电镜观察显示上肺腺管上皮细胞发生了不可逆的变性过程。
In maritime pine needles, comparisons of infrastructural and biochemical results show that a preferential site of synthesis for the monoterpene hydrocarbons (C10) is located in the epithelial cells of the resin ducts, the basal part of the needles having a higher content of monoterpenes than the upper parts. The incorporation of 14C in the monoterpenes at the base is respectively 16 and 66 times more important than at the medium and upper parts. An electron microscopic study of the evolution of the epithelial cells of the resin ducts shows a temporary activity of these cells and this activity is very intense only at the base of the needles.In contrast, the sesquiterpenes (C15) are synthesized in the whole needle according to a permanent process. The three parts of the needles present a progressive and continuous accumulation, and a significant incorporation of 14CO2 in sesquiterpenes. The electron microscopy reveals an irreversible degenerating process of the epithelial cells of the ducts in the upper par...
