Abstract: In order to study the dynamic effects of Piriformospora indica on the growth and root morphology of Pinus thunbergii seedlings, we studied the effects of Piriformospora indica on the growth and root architecture, and root fractal dimension of Pinus thunbergii seedlings. The results showed that the promoting effect of Piriformospora indica on the growth of underground roots was earlier than that on aboveground parts, and the effect was significantly higher than aboveground parts. 15 to 30 days after Piriformospora indica was inoculated, the inoculation seem to have little effect on aboveground parts, but the promotion effect on root was obvious, while the aerial part had significant growth effect on the 60th day. Inoculation of Piriformospora indica can increase the above-ground and root biomass, and also significantly improve root length, branch number, surface area, volume and other configuration parameters and root fractal dimension, and promote the growth of Pinus thunbergii.

Key words: growth effect, fractal dimension, root architectures, Pinus thunbergii, Piriformospora indica
