本文概述对湿地松单萜烯组成的变异和遗传的研究结果,举例说明如何利用所得到的结果对湿地松的遗传学进行研究.湿地松单萜烯组成的单株变异和遗传湿地松的含油树脂,约有20%是单萜烯类,其余的主要是各种树脂酸.木质组织含油树脂的单萜烯馏分主要由α-蒎烯、β-蒎烯及β-水芹烯构成;莰烯、香叶烯、α-水芹烯及苧烯常以次要成分的形式出现,偶尔还有痕量的△-3-蒈烯及γ-萜品烯.枝尖皮层组织 This paper summarizes the results of the study on the variation and inheritance of monoterpenes in Slash pine and gives an example of how to use the results obtained to study the genetics of Slash pine. Resin, about 20% is monoterpenes, the rest is mainly a variety of resin acids. The mono-terpene fraction of woody oil-containing resin is mainly composed of α-pinene, β-pinene and β-phellandrene; Olefin, myrcene, α-phellandrene and limonene are often present in the form of minor constituents with occasional trace amounts of Δ-3-carene and γ-terpinene.
