Abstract:

Seed quality is critical factor for seed germination and plant development. This study was carried out by priming of rice seeds with different concentrations (0, 25, 50, 75, 100, 125, 150, 175 and 200 ppm) of biosynthesized silica nanoparticles. Silica nanoparticles (93.14 nm) were biosynthesized by using rice husk as waste material. Result showed concentration dependent response of seed quality parameters and 125 ppm concentration of silica nanoparticles resulted significantly higher seed quality parameters as improved in seed germination (up to 10%) over control and root length (14.80 cm), shoot length (5.65 cm), seedling length (20.45 cm), seedling dry weight (106.98), seedling vigour index-I (1891), seedling vigour index-II (9895), peak value (20.50), speed of germination (26.86) and mean germination time (3.55 day) also, significantly positive response was recorded to control seed borne fungi in one month stored primed rice seeds with silica nanoparticles. The lowest infection level (5.13%) of seed borne fungi was observed in 200 ppm which was significantly on par to (5.53%) at 175 ppm and highest per cent infection level was recorded in control (9.67%). The priming method with silica nanoparticles had favourable effect on rice seed germination and seedling early growth.
