Abstract

Zinc (Zn) is an essential micronutrient with various vital metabolic, enzymatic and defensive roles in crop plants. This study was conducted to optimize the seed priming treatments, with Zn in improving the germination and early seedling growth of wheat. Experiments were conducted in petri plates and sand filled pots, respectively in Allelopathy laboratory, Department of Agronomy, University of Agriculture Faisalabad, during 2012. The experiments were laid out in completely randomized design in factorial arrangement with four replications. Seeds of two wheat cultivars Lasani-2008 and Faisalabad-2008 were soaked in aerated Zn solution of various concentrations (0.5, 0.1, 0.05, 0.01, 0.005 and  0.001 M Zn) for 12 h. Seeds soaked in aerated water for 12 h (hydropriming) and untreated dry seeds were taken as control. Wheat seeds primed in 0.1 to 0.01 M Zn solution increased the earliness, uniformity and final germination percentage in wheat. Beyond this concentration, there was adverse effect on germination and seedling growth of both wheat cultivars. Seed priming with 0.1 to 0.01 M Zn solution also improved the root and shoot length and seedling dry weight.
