Acceleration of germination of super-hard rice cultivar EM10 by soaking with red onion

Abstract

Red onion accelerated the germination of rice seeds and inhibited microbial infestation during germination. After germination with red onion for 16 h at 35 °C, super-hard rice EM10 showed a higher germination ratio (2.3 times), and it contained more GABA (2.3 times) and glucose (2.9 times) than that soaked without onion. Due to soaking with red onion, germinated EM10 was fortified with quercetin (18mg/100g).
