Effect of Foliar Application of Iron on Morpho - physiological Traits of Wheat under Drought Stress

An experiment was conducted in order to evaluate the effects of Fe spraying on quantitative and qualitative yield of Sirvan wheat new variety under water stress condition, in agriculture and natural resource research center of Tehran province in 2012 - 13. a split plot layout within randomized complete block design with three replications was used. main plots wer e three irrigation treatments (normal irrigation, non - irrigation at start of grain filling stage and non - irrigation at start of flowering stage) and sub plots were Fe spraying with two levels including spraying with pure water and Fe spraying with 0.5% con centration. The result showed that all traits significantly affected by stress except plant height. The most effect of stress at filling stage treatment was on thousand kernel weight and leaf area duration. Both two stress treatments caused a significant d ecrease of flag leaf area followed by maximum amount of LAI. Fe spraying significantly increased plant height, no. of fertile tiller and flag leaf area by 5%, 6%, and 11.7% respectively. Also, RWC increased by 8.3% respectively in this treatment. The manne r of LAI changes during wheat growth period had significantly affected by
