Fig 3. Growth enhancement of switchgrass (A, B) and sorghum (C, D) seedlings by exposure to carbon-based nanomaterials.

Fig 3

Effects on growth of bioenergy crops by CNTs (B, D) graphene (A, C) added to growth medium. Measurements were performed on 10-day-old seedlings (n = 30 for both sorghum and switchgrass). (* = p < .05 and ** = p < .01).
