GRAPHENE SUSPENSION AS A PLANT GROWTH REGULATOR
Abstract and keywords
Abstract (English):
A stimulating effect has been studied of low doses of graphene (0.2 mg/l, 2 mg/l and 20 mg/l) on two species - corn and cucumber plants. (Earlier, these species had already been studied regarding stimulation by higher doses, and suppression by even higher doses, of carbon nano-materials.) The graphene used was obtained by original supercavitation method and was characterized by electron microscopy and by the Raman scattering. The spectra of the Raman scattering indicated the presence of 1 to 5 carbon atomic layers thick nanoplates. In this investigation, the maximum stimulating effect of graphene was revealed at the graphene concentration of 20 mg/l in an aqueous suspension. At the concentration of 0.2 mg/l no stimulating effect has been detected.
