9 mycorrhizal fungi, including 4 ectomycorrhizal fungi (ECMF) and 5 arbuscular mycorrhizal fungi (AMF), were used to explore their effect on seedling growth of Mytilaria laosensis. The study shows that M. laosensis is one of the species with both VAM and ECM. Mycorrhizal infection rate of all ECM inoculation methods reached level 3, and that of AMF infection rate was 88%-93%, of which AM91 became the highest. In different periods, different inoculation treatment expressed different effects on seedling growth. At the end of the experiment, the height, ground diameter, underground dry mass and upper ground dry mass of seedling inoculated with PX0801 and 9006 respectively increased by 71%, 45%, 128%, 184%, and 65%, 54%,150%, 208%, which exhibited the best overall effect. Coinoculated seedlings with AM90036, AM3008 and AM91 had advantages over uninoculated ones in all the tested growth indicators, which suggest to significantly promote the growth of M.laosensis. The results obtained provide reference for mycorrhizal fungi application on M. laosensis.

Abstract: 9 mycorrhizal fungi, including 4 ectomycorrhizal fungi (ECMF) and 5 arbuscular mycorrhizal fungi (AMF), were used to explore their effect on seedling growth of Mytilaria laosensis. The study shows that M. laosensis is one of the species with both VAM and ECM. Mycorrhizal infection rate of all ECM inoculation methods reached level 3, and that of AMF infection rate was 88%-93%, of which AM91 became the highest. In different periods, different inoculation treatment expressed different effects on seedling growth. At the end of the experiment, the height, ground diameter, underground dry mass and upper ground dry mass of seedling inoculated with PX0801 and 9006 respectively increased by 71%, 45%, 128%, 184%, and 65%, 54%,150%, 208%, which exhibited the best overall effect. Coinoculated seedlings with AM90036, AM3008 and AM91 had advantages over uninoculated ones in all the tested growth indicators, which suggest to significantly promote the growth of M.laosensis. The results obtained provide reference for mycorrhizal fungi application on M. laosensis.
