Boron (B) plays important role in plant growth and development. This study was conducted to optimize the seed priming treatments, with B, in improving the germination and early seedling growth of wheat. Seeds of wheat cultivars Mairaj-2008 and Faisalabad-2008 were soaked in aerated B solution of various concentrations (0.001, 0.01 & 0.1% w/v) 12 h. Seeds soaked in aerated water for 12h (hydropriming) and untreated dry seeds were taken as control. Wheat seeds primed in 0.001 and 0.01% B solutions decreased the time to 50% germination and mean germination time, however did not affect the final germination. Beyond this concentration, there was adverse effect on the germination and seedling growth of both wheat cultivars. Seed priming with 0.001% B also improved the root and shoot length and seedling dry weight. Wheat seeds may be primed with 0.001% B to have better and uniform stand and early seedling growth of wheat.
