Abstract

This experiment was carried out in fall in 2006 to study the effect of selenium on YIELD and YIELD components of two varieties of WHEAT (Azar2 & Pishtaz). The seeds of both varieties of WHEAT planted in normal and DROUGHT STRESS (Stopping the irrigation) conditions. Sodium Selenate (Na2SeO35H2O) was sprayed in 3 levels (b1=withness, b2=20mg/lit and b3=25mg/lit) on booting stage. The experimental design was arranged on Factorial split plot with 4 replications. DROUGHT STRESS (Stopping the irrigation) and selenium used as factorial in main plot and WHEAT varieties in sub plot. In this experiment, factor (a) was named for irrigation treatment, factor (b) for Selenium treatment and factor(c) for WHEAT varieties. The most important assessed traits in the field were measuring of the Spike weight, Grain YIELD, Harvest Index(HI), Thousand grain weight, Mean of the number of total tillers- fertile tillers and Mean of the Spike length. We also assessed the RWC in the lab. The results of the field experiments showed that the traits as Spike weight and Grain YIELD had significant differences in various condition of irrigation. In well water condition, Spike weight and Grain YIELD were more than lack of the water condition. The results also showed the significant differences between the Spike weight and the Grain YIELD in varieties of WHEAT. PISHTAZ VARIETY had more Spike weight and Grain YIELD than Azar2. In Harvest Index (HI), there was no significant difference in various levels of Irrigation and Selenium spraying but we observed significant difference in varieties. AZAR2 VARIETY had more HI than PISHTAZ VARIETY. In thousand grain weight trait, there was significant difference in the different levels of watering. We had more thousand grain weight in well water condition than lack of the water condition. The various levels of Selenium spraying was not effective on thousand grain weight and showed no significant difference. Also AZAR2 VARIETY had more thousand grain weight than Pishtaz. In the Mean of the number of total tillers- fertile tillers traits different levels of watering and selenium spraying showed no significant difference but these traits had significant difference between the varieties of WHEAT. The PISHTAZ VARIETY was superior about Mean of the number of total tillers and fertile tillers traits than Azar2. The Spike length trait had not significant difference in none of the various levels of watering, selenium spraying and varieties of WHEAT treatments. The separate assessed trait in the laboratory was measuring the percentage of relative water content of the leaf. Experimental results showed that the RWC had significant differences between the levels of watering in statistical analyses. In well water condition, the RWC was obviously more than lack of the water condition. The RWC showed no significant difference in various treatments of selenium spraying and WHEAT varieties.
