Abstract

The impacts of silicon dioxide nanoparticles (SiO2NPs) at different concentrations (0, 25, 50, 75, 100 and 125 mg/L) on seed germination and growth of seedlings in three genotypes (HHB-67, RHB-173, and MPMH-17) of Pennisetum glaucum ((L.) R. Br.) were investigated by seed priming method. Among the various tested concentrations, 75 mg/L of SiO2NPs enhanced final germination percentage (FGP), seed vigour index-1 (SVI-I), seed vigour index-II (SVI-II), seedling fresh weight and dry weight of genotype HHB-67 and RHB-173 in comparison to untreated seedlings. But in genotype MPMH-17, the germination parameters were enhanced at 50 mg/L of SiO2NPs concentration in comparison to control. This study clearly indicates that SiO2NPs boosts several germination parameters along with overall growth of Pennisetum. This positive role of SiO2NPs is dosage dependent and after a threshold, it shows negative impacts on germination parameters.
