Abstract: The present study was aimed to evaluate the Effects of silica nanoparticles and GA3 loaded silica nanoparticles (SiO2) effects on comparative efficiency of invigoration techniques on seed germinability of maize varieties. The present investigation was carried out at G.B.P.U.A.T., Pantnagar, Uttarakhand under laboratory condition. The ten month aged seeds of six maize varieties viz. Amar, PSM-3, D-765, Tarun, Sweta and Navin along with seven invigoration treatments i.e. control, nanosilica 8g/l, GA3 100 ppm, 100 ppm GA3 loaded nanosilica, 125 ppm GA3 loaded nanosilica, 150 ppm GA3 loaded nanosilica and 100 ppm PEG loaded nanosilica. Results also depicted that D-765 maize variety had significantly maximum value for seed quality parameters including standard germination percentage, germination value, germinative energy, mean daily germination and peak value after 10 month of ageing. The results of experiment showed that ten month aged seeds invigorated with T5 recorded higher value for all the seed quality parameters and increase 23% germination as compared to control. Ten month aged seeds of D-765 maize variety reported highest value for seed quality parameters including standard germination percentage, germination value, germinative energy, mean daily germination and peak value. The results showed that the variety D-765 was minimum deteriorated after the ten month of ageing. Therefore, it is very clear that delivery of GA3 through nanosilica (nSiO2) has a significant impact on the seed germination potential.
