Effects of different concentrations of PsJN on switchgrass cv. Alamo growth with direct inoculation of seeds that were imbibed in water for different days (1-4 days). The seeds were infected with different concentrations of PsJN and grown in vitro for 25 days, then transferred to 72-cavity trays and grown in a growth chamber for 37 days. Sample number was 72 for each treatment. * and ** mean significant difference at 0.05 and 0.01 levels respectively between PsJN and control using student T-test.
