摘　　要：于2018年对6个芳樟无性系(NP_(114)、NP_(187)、PC_(1)、PC_(6017)、MD_(1)、MD_(2))在南平、永安和厦门的生长指标(树高、胸径、材积)和叶精油含量进行测定,探讨其在福建不同区域的丰产性、稳定性和适应性,并筛选适宜的油材两用型芳樟无性系。结果表明:6个芳樟无性系12年生时树高、胸径、材积和叶精油含量均存在显著(P<0.05)或极显著性差异(P<0.01)。从叶精油含量看,6个无性系叶精油含量遗传稳定性强,适合在福建3个区域栽植,其中PC_(1)精油性状最为高产稳定;从生长性状方面看,6个无性系的树高、胸径遗传稳定性较强,但需加强除干和修枝以利于优质干材的培育,其中,NP_(114)材积性状最为高产稳定。综合分析结果表明:南平地区无适宜的油材两用型的芳樟无性系;MD_(1)、PC_(1)为适宜永安地区的油材两用型的芳樟无性系;MD_(2)、MD_(1)和PC 6017为适宜厦门地区的油材两用型的芳樟无性系。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,PC_(1) 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 NP_(114) 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;MD_(1) and PC_(1) were suitable oil and wood dual-use C.camphora var.linaloolifera Fujita clones for the Yong′an region;MD_(2),MD_(1) and PC_(6017) were suitable oil and wood dual-use C.camphora var.linaloolifera Fujita clones for the Xiamen region.
