86 The Increase of Seedling Vigour in Wheat by TiO₂ Nanoparticles Application

In order to evaluate nanopriming effect on the quality seedling production during germination in wheat (Triticum aestivum L.), this experiment was conducted in 2011 at Laboratory Sciences, Islamic Azad University Shahr-e-Qods Branch by a completely randomized design with three replications and the first, seed viability was determined by Tetrazolium test method. The factor studied included different spry of TiO₂ (Control, 0.01 and 0.02 percentage). The results showed that the effect of nanopriming was significant on germination percentage, seedling dry weight and seedling vigour in P ≤ 0.05⁠. Mean comparison showed that the highest germination percentage (97 %), seedling dry weight (1.09 g), seedling vigour (105.73), and seedling length (13.05) were achieved by spry of 0.02 TiO₂.
