Effect of different treatments

Delaying in planting and low precipitation are the major problem in wheat (Triticum aestivum L.) farming in Iran. To evaluate the effects of inducing of drought tolerance under field conditions an experiment was done in 2009 at Agricultural research center in western Azerbaijan under well-water and drought stress. The experiment was Split-plot factorial in randomized complete blocks Design with three replications, in which two irrigation conditions includes well water and drought stress as main plots and factorial of two cultivars (Zarrin, and Sardary) and Hardening includes osmotic solutions 10% polyethylene glycol (8000), 3% sodium chloride and 2.5% KCL) and plant growth regulator (10 ppm IAA) by control as subplots. Drought stress obtained by cut irrigation from rapid stem development stage. Result showed that besides traits RWC of flag leaf and fertile stems other traits such as grain yield, number of spike per square meter, number of seed per spike, number of spikelet per spike, total dry mater, 1000- number of seed weight, flag leaf area, Plant height and leaf chlorophyll content had significant different at 5% level. Seed priming can improve many traits such as yield that increase (35 percent) in priming with plant growth regulators (IAA) optimalgrowth condition. Besides the Hormonal priming, Hydropriming and Hardening results showed that close to the Hormonal priming because of the high cost of priming with growth regulators, Hydropriming recommended to use. Priming of seeds is accelerated plant growth stages and thereby reduced to a minimum level of farm irrigation. According to the country’s arid and semiarid climates seed treatment is essential.
