 ABSTRACT

The present investigation was conducted at the Department of Seed Science and Technology, CCS Haryana Agricultural University Hisar. The study was planned to determine the effect of aging and priming on seed storage proteins of barley under natural and artificial aged conditions. An effort was also made to define the stability of improvement in seed vigor due to priming. A study was conducted on six barley genotypes Viz.ALFA-93, BH-393,BH-75,BCU-3,RD-2552 and K-551. All Six varieties was divided in two seed lots subjected to accelerated ageing at 42+1°C for 72 hrs on 100% relative humidity.  Both fresh and accelerated aged seeds of genotype BH-75 and BH-393 were primed by soaking in water and in an aqueous solution (27.3 gm/ litre) of polyethylene glycol 6000 (PEG 6000) providing an osmotic potential of -1Mpa (Michel & Kaufnann, 1973) for varible time period (12,18,24 &30 hrs) and different observation related to seed vigour i.e. standard germination, vigor index, rate of germination and dehydrogenase activity was recorded. The present study revealed that priming with water and aqueous solution of PEG 6000 significantly increased the standard germination, rate of germination, dehdrogenase activity and vigor index in both the varieties by boosting the repair mechanism of seed. Among all the priming treatments seed soaking of 12 hrs was found most effective.
