This is the first report on population variability of nonacosan-10-ol and n-alkanes in needle epicuticular waxes of Macedonian pine (Pinus peuce GRISEB.) Hexane extracts of needle samples, originating from two natural populations in Montenegro (Zeletin and Sjekirica) and from one population in Serbia (Mokra Gora) were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The amount of nonacosan-10-ol varied individually from 41.3 to 72.31% (average 55.9%), with the Sjekirica population being statistically divergent (64.4% on average). The results showed n-alkanes in epicuticular waxes ranging from C₁₈ to C₃₃. The most abundant alkanes were C₂₉, C₂₅, C₂₇, and C₂₃ (15.5, 11.1, 10.6, and 10.5% on average, resp.). The carbon preference index of Pinus peuce ranged from 1.0 to 4.3 (1.9 on average). Average chain length ranged from 18.4 to 27.7 (average 25.7). A high level of inidividual quantitative variation in all of these hydrocarbon parameters was also detected. These results were compared with published data on other species from the Pinus genus.
这是关于马其顿松（Pinus peuce GRISEB.）针叶表皮蜡中非acosanan-10-醇和正烷烃的种群变异性的第一份报告。对来自黑山的两个自然种群（泽利廷和谢基里察）和塞尔维亚的一个种群（莫克拉戈拉）的针叶样本的正己烷提取物进行了气相色谱（GC）和气相色谱/质谱（GC/MS）分析。非acosanan-10-醇的含量个体差异从 41.3%到 72.31%（平均 55.9%），其中谢基里察种群存在统计学差异（平均 64.4%）。结果表明，表皮蜡中有从 C₁₈ 到 C₃₃ 的正烷烃。最丰富的烷烃为 C₂₉、C₂₅、C₂₇ 和 C₂₃（平均分别为 15.5%、11.1%、10.6%和 10.5%）。Pinus peuce 的碳偏好指数范围为 1.0 至 4.3（平均 1.9）。平均链长范围为 18.4 至 27.7（平均 25.7）。所有这些烃参数的个体定量变化水平都很高。将这些结果与来自松属其他物种的已发表数据进行了比较。
