Studies on effect of carbon based nanomaterial, novel plant growth promoting agents on growth of jasmine (Jasminum sambac Ait.)

Abstract

Multi-carbon nanotubes (MWCNTs) having an average particle size of 71.81 nm with different concentration of MWCNTs (3 and 7 g/L) and graphene oxide having a diameter of 65.99 nm with different concentrations (20 and 40 mg/L), hydrogen rich water (500 ppb and 1000 ppb) and with three concentration of sodium hydrosulfide (0.5 mg, 5 mg, 50 mg) as foliar spry along with absolute control (Deionized water) were used as a foliar spray at 15 days interval during 60 days of growth period in jasmine (Jasminum sambac). This study provided some insights into the use of carbon based Nano-materials. The multi-walled carbon nanotubes (MWCNTs) with 3 g/L treated plants had maximum plant height (57.91 cm), internodal length (4.94 cm), number of leaves (170.55), plant spread E-W (46.01 cm), N-S (55.69 cm), Whereas, graphene oxide treated plant with 20 mg/L showed a promotional effect on plant growth attributes.
