Abstract: In this study, copper content of soil and irrigation water and copper content of leaves and grain of wheat (Triticum spp.) were studied. Study samples of soil, leaf and grain were collected from wheat (Triticum spp.) fields in Cukurova Region of Turkey. Soil samples taken from the root area of plants where the leaf and grain samples were collected and analyzed for copper (Cu) content. The leaf samples taken during the stem elongation and the grain samples taken at the time of maturation were also analyzed for Cu content. The correlation analysis between soil-Cu contents and leaf and grain-Cu contents was performed to determine the relationships among the variables. The Cu content of the soil samples collected in 2005 was between 0.78 and 1.56 mg kg-1. The Cu content of the soil samples collected in 2006 was between 1.12 and 1.96 mg kg-1. The copper content of the majority of soil samples, collected in 2005 was observed above the critical level which is 1 mg kg-1. The Cu content of the leaf samples was ranged from 26.30 to 67.60 mg kg-1 in 2005 and 3.06 to 18.02 mg kg-1 in 2006, whereas the copper content of the grain samples was ranged from 11.77 to 17.89 mg kg-1 in 2005 and 7.37 to 14.06 mg kg-1 in 2006. According to data analysis performed in collected samples, the Cu content of the leaf and grain samples was directly correlated with the Cu content of the soil. Correlation between copper content of soil and copper content of leaf in 2006 are significant at the 0.01 level based on the statistical analysis. Also, correlation between copper content of soil and weight of 1000 grain in 2005 and in 2006 are significant at the 0.01 level in respect of statistical analysis.
