Abstract:

An alternative strategy to ameliorate salt stress could be to use exogenous application of plant growth stimulators. The present investigation was carried out to study the effects of hormonal priming with ascorbic acid and gibberellic acid on wheat (Triticum astivum L.) metabolism during germination phase under saline conditions. Seeds of wheat var. GW- 496 were pre-soaked in three levels each of ascorbic acid (AsA) viz., (50, 100 and 150 mg L1) and gibberellic acid (GA3) viz., (150, 200 and 250 mg L-1) for 2 hrs under salinity stress given by treating with NaCl @ 50, 75 and 100 mM with four replications. The result showed that seeds primed with 100 mg L-1 AsA and 250 mg L-1 GA3 effectively enhances seed moisture content, germination percentage, germination index, root/shoot length ratio, root/ shoot fresh weight ratio and vigour index I. However, among biochemical parameters application of 100 mg L-1 AsA and 150 mg L-1 GA3 enhanced proline content. Seeds primed with 100 mg L-1 AsA and 250 mg L-1 GA3 effectively enhanced polyphenol oxidase activity. It could be concluded that, pretreatment of wheat cultivar with AsA and GA3 could partially alleviate the harmful effect of salinity by increasing vigour, antioxidative enzymes activity and accumulation of osmolytes.
