Abstract
Dark septate endophytes (DSEs) and Phosphate-solubilizing fungi (PSFs) are widely distributed and have important application value in improving plant growth. However, the effects of DSE fungi with phosphate-solubilizing ability on host plants need further study. In this study, phosphorus-dissolving DSE fungi were screened for growth-promoting effects. We isolated, identified and characterized three DSE fungal species (Thozetella neonivea, Pezicula ericae and Hyaloscyphaceae sp.) showing phosphate-solubilizing ability. The impact of three single or dual inoculations of DSEs on blueberry plant characteristics was studied. Their effects on colonization intensity, biomass in seedlings, nutrients in plants and soil, and activities of plant resistance enzymes and soil enzymes were remarkably upregulated relative to the control (p < 0.05). The available phosphorus and acid phosphatase in different combinations were significantly increased. These findings indicate that the application of three DSEs may be valuable to facilitate the cultivation of blueberry with a higher biomass and improved plant quality.
