Abstract
Laboratory and field studies were conducted to evaluate the influence of seed priming on physiological parameters of fresh and aged seeds of maize hybrid (COH(M) 5) and its parental lines UMI 285 (female) and UMI 61 (male). Seeds were soaked in water, 1% KH2PO4, 3% KNO3 and 2% CaCl2 solution for 6 hrs. The result revealed that seed priming with 1% KH2PO4 for 6 hrs showed an increased physiological performance in fresh and aged seeds of UMI 285, UMI 61 and COH(M) 5. The increased physiological performance was observed in terms of increased germination percentage, shoot length, root length, dry matter production and vigour index; accompanied with earlier germination in terms of days to 50% germination and days to maximum germination. Increased field emergence potential was also observed in the seeds primed with 1% KH2PO4 for 6 hrs. However, more pronounced effect of seed priming with 1% KH2PO4 for 6 hrs was observed in aged seeds than in fresh seeds
