Waterlogging is an important factor which is influence on nutrient uptake. Therefore, in this study, the uptake and distribution of nutrients ions in different parts of plant were investigted in wheat cultivars. This study was conducted at the Agricultural Research Station, Islamic Azad University- Ahvaz Branch. Experimental design was a factorial according to randomized complete block design (RCBD) with three replications. In this experiment three wheat cultivars namely “Chamran”, “Dez” and “Verry/nac” were used. These were grown under no-waterlogging (control), 7 days and 14 days of waterlogging. Meanwhile, waterlogging treatments for each cultivar were given separately at three different growth stages namely at the beginning of tillering stage, at the beginning of stem elongation stage and at the commencement of booting stage. The results showed that the concentration of N, K, Fe, Mn, Cu and Zn in root, stem and seed did not affect when waterlogging was applied at different growth stages, significantly. Duration of waterlogging significantly decreased concentration of N, K, Cu and Zn in all parts of plant. The concentration of Fe and Mn in the root increased significantly after duration of waterlogging, but decreased in stem and seed. Results also showed a significant difference between tested wheat cultivars for concentration of N, K, Fe, Mn, Cu and Zn in all parts of plant.
