摘要: 为了研究不同杂种松的产脂力及松脂成分的差异,对21年生湿地松(PEE)与加勒比松(PCH和PCB)的5个不同杂种的产脂力、松脂成分进行方差分析与相关分析。结果表明:杂交松及其对照样的产脂力差异显著,其中3个杂种(PEE×PCH、PCH×PEE、PEE×PCB、(PCH×PEE)×PEE、PCH×(PCH×PEE))产脂力分别比3个对照样(PEE、PCH和PCB)均值高74.55%、23.27%、37.19%、65.26%、46.71%,其中PEE×PCH杂种产脂力表现最优;杂种及其对照仅松脂含油量、β-蒎烯、柠檬烯、左旋海松酸、去氢枞酸、新枞酸差异显著。松脂含油量、单萜中α-蒎烯、β-蒎烯含量最高的杂种分别为PEE×PCH(31.02%)、PEE×PCB(23.24%)、PEE×PCH(14.70%);左旋海松酸、去氢枞酸、新枞酸含量最高杂种分别为PEE×PCH(28.38%)、PCH×(PCH×PEE)(4.34%)、(PCH×PEE)×PEE(11.46%)。PEE×PCH杂种产脂力与松脂性状的相关分析表明,产脂力与松脂性状相关性不显著,含油量、β-蒎烯、柠檬烯、左旋海松酸之间的某种或某几种存在相关性。

Abstract: In order to study the resin-producing capacity of different hybrid pines and the content of oleoresin, the variance and correlation analysis of resin-producing capacity and oleoresin composition of five 21-year-old hybrid pines of slash pine(PEE) and caribbean pine(PCH and PCB) and their contrast were conducted.The results showed that there was significant difference in resin-producing capacity between hybrid pine and its contrast. Lipid production ratios of 3 hybrid pines(PEE×PCH, PCH×PEE, PEE×PCB, (PCH×PEE)×PEE, PCH×(PCH×PEE)) were higher than the average of the 3 contrast by 74.55%, 23.27%, 37.19%, 65.26%, 46.71%. PEE×PCH combination had the best resin-producing capacity. Turpentine oil, β-pinene, limonene,levopimaric acid, abietic acid, neoabietic acid of different combinations had significant difference. The highest content of hybrids turpentine oil and α-pinene, β-pinene were PEE×PCH(31.02%), PEE×PCB(23.24%), PEE×PCH(14.7%), respectively. The highest levopimaric acid, abietic acid, neoabietic acid content in combinations were PEE×PCH(28.38%), PCH×(PCH×PEE)(4.34%),(PCH×PEE)×PEE(11.46%), respectively. The correlation analysis of PEE×PCH combination showed that there was no significant correlation between the resin-producing capacity and oleoresin composition, but some of oil content, β-pinene, limonene, levopimaric acid were significantly correlated.
