Regional Experiment and Evaluation of Growth and Leaf Essential Oil Characteristics of Cinnamomum camphora var.linaloolifera Clones

By measuring the growth indicators（tree height, breast height diameter and volume） and leaf essential oil content of six Cinnamomum camphora var.linalooifera Fujita clones in Nanping, Yong′an and Xiamen, the high yield, stability, adaptability, and selection of oil wood dual-use C.camphora clones in Fujian region were analyzed using variety regional experiments.The results showed that there were significant（P＜0.05） or extremely significant（P＜0.01） differences in tree height, breast height diameter, volume and leaf essential oil content among different clones of Camphor trees.From the perspective of leaf essential oil content, the six clones have strong genetic stability in leaf essential oil content and are suitable for planting in three regions of Fujian.Among them, PC₁ has the highest yield and stability in essential oil traits; from the perspective of growth traits, the six clones have strong genetic stability in terms of tree height and breast height diameter, but it is necessary to strengthen stem removal and pruning to facilitate the cultivation of high-quality dry wood.Among them, the NP₁₁₄ volume trait is the most high-yield and stable.The comprehensive analysis results indicate that there were no suitable oil and wood dual-use C.camphora var.linaloolifera Fujita clones in Nanping region; MD₁ and PC₁ were suitable oil and wood dual-use C.camphora var.linaloolifera Fujita clones for the Yong′an region; MD₂, MD₁ and PC₆₀₁₇ were suitable oil and wood dual-use C.camphora var.linaloolifera Fujita clones for the Xiamen region.
