Seed preconditioning, a short gun approach to modulate the effects of abiotic stresses on crop plants, has recently gained considerable attention of the researchers to induce salinity tolerance in agronomically important crops. The present study was conducted to explore the comparative efficacy of presowing seed priming with silicon (Si) and Si fertigation to modulate the wheat growth and ion dynamics. Seeds of wheat variety, PUNJAB-11, were sown in Petri plates having nutrient solutions with (120 mM) and without NaCl. Six levels of Si (0, 10, 20, 30, 40, or 50 mM), applied as sodium silicate (Na2SiO3), were tested either as a seed priming agent or as a supplement in the nutrient solution. Priming of seeds with Si mitigated the adverse effects of salinity stress on germination percentage, root as well as shoot length, dry and fresh weight. Application of Si either as preconditioning of seeds or addition in the growth medium resulted in reduced accumulation of sodium (Na(+)) in wheat seedlings under saline environment. Seedling's potassium (K(+)) contents either remained unaffected or decreased whereas calcium (Ca(2+)) contents decreased at all Si concentrations except at 30 mM when Si primed seeds were grown under salt stress. Addition of Si, under salt stress, in cultivation medium exerted a positive effect on seedling's K(+) and Ca(2+) contents. Silicon contribution to decontamination strategies was evaluated.
