Activation of seed germination by application of CBNs in cotton and Catharanthus under salt stress. Effects of graphene (A,C) and CNTs (B,D) on seed germination of Catharanthus (A,B) and cotton (C,D) exposed to salty growth media. 50 mM NaCl and 100 mM NaCl were used to impose salt stress in Catharanthus and cotton, respectively. The seed germination experiments were repeated twice (n = 60 for each treatment of cotton and Catharanthus) The statistical significance was determined as compared to seeds exposed to only NaCl by p < 0.05 and p < 0.01 (*p < 0.05 and**p < 0.01).
