本研究显示了在古巴Pinar del里约热内卢省的三个地点测定的加勒比松（Pinus caribaea var caribaea）木材样品中的木质素含量及其质量（H/G比）。这项研究是在葡萄牙里斯本热带科学调查研究所（GEMA项目）进行的。分析方法为解析热解法。所得结果为三次重复的平均值，与克拉松法相近。结果表明，木素含量与木素含量之间存在一定的相关性。这就有可能通过木质素含量来计算木质素含量。分析热解法在遗传改良项目中有很大的应用价值，因为在遗传改良项目中需要对许多样品进行分析
This work shows the lignin content determined as well as its quality (H/G ratio) in wood samples of Pinus caribaea var caribaea from three sites at Pinar del Rio Province, Cuba. The study was carried out at the Tropical Scientific Investigation Institute, Lisbon, Portugal (Project GEMA). The Analytical pyrolysis was used as analytical method. The results represent the average of three repetitions and was obtained similar values to Klason method used as reference. An acceptable correlation was obtained between the Py-lignin contents and Klason lignin for this species. This may be possible to calculate the Klason lignin through the content Py-lignin content. The Analytic pyrolysis is of great utility in the programs of genetic improvement, in which it is necessary the analysis of many samples, since the
