Effect of Seed Size on Seedling Production in Wheat (Triticum aestivum L.)

In plants encouraged by the proliferation of seed, seed to plant survival factor to maintain the role is very vital and important. In order to evaluate different size effect's 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 factors studied included different size of wheat seed (small, medium and large). The results showed that the effect of seed size 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 came up to large seeds.
