The Effects of Seed Priming Using Distillate Water and Different Rates of Selenium on Germination, Seedling Growth Traits and Seed Yield of Dryland Wheat in Laboratory and Field Condition

This study was carried out to investigate the effects of different treatments of  priming  on  seedlings traits and seed yield of dryland wheat in labratory and field condition with three replications at the Research Station of Islamic Azad University, Arak Branch, in 2014. The experimental treatments in labratory were control, seed priming with distillate water and priming with rates of 1, 2 and 3m/L Se conducted in a completely randomized design.  In field condition was also used mentiend treatments along with foliar application in a randomized complete block design. The result showed that the minimum mean germination time was 2.62 day in priming with 1m/L Se. Seed priming with distillate water and  priming with 1, 2 and 3m/L Se increased seedling length  by 28.5, 54.4, 49.1 and 48.5 % , respectively, as compared with control. Seed priming with 3m/L Se increased seedling vigor length index by 1.6 times as compared with control. Seed priming with 3m/L Se increased the plumule dry weight and root dry weight by 44.4 and 46.5% , respectively, as compared with control. Seed priming with 1 m/L Se increased the chlorophyll b by 19.3 as compared with control. The result showed that seed priming with 1 and 2 m/L Se along with foliar application of Se  and priming with distillate water along with foliar application of Se  increased seed yield  by 16.7, 19 and 17.9%, respectively, as compared with control. General results of this trail showed that seed priming with low selenium along with selenium spray under dryland condition, optimum yield of wheat can be achieved.
