Enhancement of seed germination of fiber-producing and ornamental species by the application of CBNs. Effects of CNTs (A,C) and graphene (B,D) added to the growth medium on seed germination of Catharanthus (A,B) and cotton (C,D). The presented graph shows the percentage of seed germination by exposures to CBNs at a concentration of 50 µg/ml and 200 µg/ml. The entire seed germination experiments were repeated twice (n = 60 for each treatment and for conrol). The statistical significance was determined as compared to control (untreated) seeds by p < 0.05 and p < 0.01 (**p < 0.01 and *p < 0.05).
