目的：研究4 种AM 真菌对苍术根茎生长及其挥发油成分的影响。方法：采用盆栽试验，接种AM 菌剂，测定苍术地下部分生长状况和根茎挥发油成分的含量。结果：不同AM 真菌对苍术根茎的侵染率不同，接种AM 真菌能显著降低苍术根茎的折干率，而对根茎挥发油中5 种主要成分含量均无明显影响。结论：AM 真菌与植物之间具有选择性。不同AM 真菌对苍术地下部分的营养生长存在差异，但对苍术挥发油的品质无显著性影响（P>0.05）。

The effects of four AM fungi on the growth and essential oil composition in rhizome of Atractylodes lancea were studied by pot experiments with or without AM fungi. The fresh weight and dry weight of underground parts and the content of essential oil composition of A. lancea were determined. The results showed that the infection rate of different AM fungi differed greatly. The drying rate in rhizome of A. lancea was significantly reduced in AM treatments, although the contents of main essential oil compounds were unchanged. In conclusion, there are selective interactions between AM fungi and A. lancea. AM fungi have significant impact on vegetative growth of the underground parts of A. lancea, whereas the quality of essential oil does not change significantly.
