Fig 4.
The shoot dry weights of the switchgrass plants.
The plants were treated with water control and the water broth containing diverse fungal spores and mycelia at 8 weeks under greenhouse condition. The triangle represents the significant difference existing between the fungal broth treated and water treated plants; the data were further analyzed by the Student’s t-test (P<0.05).
