Abstract:
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 Xiamen region.
