Figure 8From: Growth promotion and colonization of switchgrass (Panicum virgatum) cv. Alamo by bacterial endophyte Burkholderia phytofirmans strain PsJNEffects 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.
