The effects of arbuscular mycorrhizal fungi (AMF) Glomus mosseae on the growth index and the root exudates chemical composition of Artemisia annua L. were studied under potted conditions. The results showed that the height, shoot dry weight and root dry weight of A. annua inoculated with AMF increased significantly, with an increase of more than 20%; in addition to root radius, root length, root surface area, root volume, tips, forks and root activity of A. annua increased by 87.0%, 97.0%, 10.7%, 38.4%, 75.6% and 19.6%, respectively; compared with the root exudates obtained from the matrix of A. annua without AMF inoculation (NM-S), the content of soluble protein, soluble sugar and free amino acid in the root exudates obtained from matrix of A. annua with AMF inoculation (AM-S) increased by 74.38%, 16.13% and 203%, respectively, following the types and contents of organic acids increased significantly; but the effects of AMF on the root exudates of hydroponic solution showed an opposite trend. In the substrate, AMF may improve root morphology, root activity and secretion of the root exudates so that A. annua could absorb more nutrients and improve its biomass.

Key words: arbuscular mycorrhizal fungi, Artemisia annua L., root exudates
