摘　　要：芳樟[Cinnamomumcamphoravar．1inaloolifelaFujita．]个体自然结果率极低，甚至只开花不结实，而其群体结果率却较高。通过自然授粉繁殖的芳樟子代叶精油类型（主要成分）存在分离现象，如叶精油主含芳樟醇的母株，可产生叶精油主含樟脑和桉叶油素的有性后代，且后代个体间芳樟醇含量差异大怛。Essential oil content and linalool relative content in leaf of excellent individual of Cinnamomum camphora var. linaloolifera Fujita. clones and their variation states were compared. The result shows that essential oil content of the maternal plant is 1.78% and its linalool relative content is 97.56%. Average content of essential oil in leaf of the first and the second generation clones of tissue culture and their cutting clone is 1.65%, 1.60% and 1.58% with CV values of 9.09% , 7.50% and 7.59% , respectively, and average relative content of finalool in these clones is 94.32% , 94.52% and 94.60% with CV values of 0.60%, 0.73% and 0.73%, respectively. There is some difference in essential oil content and linalool relative content between the first generation clone of tissue culture and the maternal plant, but the difference is small. Essential oil content and linalool relative content among these clones have no significant difference and those are stable within clones, indicating the clonal progeny can keep their parent＇ s good traits.
