澳大利亚杂交松产脂量及松脂成分研究

Study on the Output of Resin and Its Chemical Composition from Australia Pine Hybrid

研究表明,7年生杂交松50天内产脂量为588 g/株,分别比湿地松、加勒比松、马尾松高9.91%、23.01%、68.48%;全年产脂量3 057 kg/hm2,分别比湿地松、加勒比松和马尾松高43.1%、59.9%、82.5%。产脂量与树高胸径综合指数密切相关。杂交松松脂成分与湿地松、加勒比松相比,没有显著差别;与马尾松相比,除左旋海松酸偏低、去氢枞酸偏高外,其余组成成分差异不显著。

The study showed that the resin output of Australia hybrid pine of 7 years old was 588g of per tree in 50 days and it was higher than that of Slash pine, Caribbean pine and Masson pine by 9.91% ,23.01% ,68.48% respectively. The resin output of Australia hybrid pine was 3 057 kg/hm2 in whole year and it was higher than that of Slash pine, Caribbean pine and Masson pine by 43.1% ,59.9% ,82.5% respectively. The resin output of Australia hybrid pine was related to the index of the tree height and its diameter. The study also showed that the resin chemical compositions of Australia hybrid pine, Slash pine, Caribbean pine and Massou pine were very similar. There was no any difference between Australia hybrid pine and Slash pine or between Australia hybrid pine and Caribbean pine in the chemical composition. There was a little difference between Australia hybrid pine and the Masson pine.
