Abstract

Background and Objectives: One of the approaches that attracted attentions since the early time and has recently gained more importance is the use of plant genotypes efficient at uptake and utilization of nutrients. Recently, these efficient plant genotypes have attracted researchers’ attention. Their use in low input agriculture is a new way of increasing the efficiency of fertilizers. Iron and Zinc are essential macronutrient for plants. These macronutrients are very important for human nutrition as well. The purpose of this study was to identify the efficient genotypes on Use efficiency of Iron and Zinc as well as enriching Wheat seeds with these two nutrients. Materials and Methods: The experiment was conducted as a factorial in a completely randomized design with three replications in order to investigate use and uptake efficiencies of Iron and Zinc in bread Wheat genotypes. The first experimental factor included 12 different Wheat genotypes and the second factor was 4 fertilizer levels. These Wheat genotypes were N87-20, Morvarid, Gonbad, Falat, Tajan, Line90-7, Line91-17, Aftab, Ghabus, Kouhdasht, Karim and Line17. Fertilizer treatments consisted of complete nutrient solution, Iron deficient complete nutrient solution, complete nutrient solution without Zinc and Iron and Zinc deficient complete nutrient solution. Zinc sulfate at zero (deficiency level) and 1μ M (sufficiency level) and sequestrene at 1μ M (deficiency level) and 100μ M (sufficiency level) were supplied as sources of Iron and Zinc. Results: The results showed that shoot dry weight and Iron and Zinc uptake of shoot significantly decreased in Iron and Zinc deficient treatments, but, the Use efficiency of Iron and Zinc in these treatments increased. These indices in treatment with both Iron and Zinc deficiency decreased in comparison with only Iron or only Zinc deficient treatment. However, the Use efficiency of these genotypes increased. Line 90-7 had the highest Iron Use efficiency and line 17 had the lowest one. In contrast, line 17 had the highest Zinc Use efficiency and Kouhdasht, Tajan, Karim and Ghabus genotypes had the lowest ones. Classification of genotypes based on Dry matter weight and Use efficiency of shoot Iron and Zinc (Gill’ s method) showed that the Line 90-7 and N87-20 were high responsive to Iron and Zinc supply respectively and the Line 90-7 and Line17 were high efficient at Iron and Zinc use respectively. The findings also showed that the Tajan and N87-20 were the best and Line17 and Kouhdasht were poor in uptake and use of Iron and Zinc and production of Dry matter. Conclusion: The results of this study indicated that in greenhouse conditions Tajan and N87-20 genotypes were responsive to Iron and Zinc fertilizers. They were also efficient in using Iron and Zinc and producing high Dry matter. However, further field trial of these cultivars in both high and low fertile lands (Iron and Zinc deficient lands) is suggested.
