Effects of endophyte PsJN inoculation on switchgrass cv. Alamo growth in growth chamber. The seedlings were inoculated with PsJN and grown in vitro for one month, then transferred to soil and grown in growth chamber for another month. Dry weight was determined after samples were dried in oven at 65°C for one day. Sample number was 36, and ** means significant difference at 0.01 level between PsJN and control using student T-test.
