ABSTRACT = {Pinus elliottii is an exotic afforestation pine extensively distributed in
southern parts of China. In order to understand whether endophytic fungi can
affect seedling growth of P. elliottii, Piriformospora indica (Pi), Funnelifcrmis
mosseae (Fm), and Diversispora tortuosa (Dt) were inoculated respectively,
and the non-inoculated group was set as control. The growth indexes, the contents
of soluble sugar and soluble protein, and plant endogenous hormone levels in the
leaves of P. elliottii, were analyzed. The results showed that Fm, Dt and Pi colonized
the P. elliottii roots to form mycorrhizal structure and chlamydospores
arranged in beads respectively. Three fungal inoculants exhibited the stimulated
growth responses, whilst Dt illustrated the most positive effect on plant height, single
fresh weight, trunk diameter and root system structure, compared with the control.
On the other hand, the soluble sugar and soluble protein contents were
increased distinctively in mycorrhizal plants. The endogenous IAA, GA3, ZR contents
were increased, while the ABA contents were reduced in mycorrhizal plants
versus non-mycorrhizal plants. The fungi-induced endogenous hormone changes
triggered plant growth improvement of P. elliottii seedlings. This research unraveled
the positive effect of AM fungi and P. indica on growth of pine seedlings, while,
more application of endophytic fungi to fields needs to be explored.},
