The Effects of Iron Content of Soils on the Iron Content of Plants in the Cukurova Region of Turkey

S. Irmak, A.K. Surucu and S. Aydin
Soil, leaf and grain samples were collected from wheat (Triticum sp.) fields in Cukurova Region of Turkey and the soil samples taken from the root area of plants where the leaf and grain samples were obtained were analysed for iron (Fe) content. The leaf samples taken during the stem development and the grain samples taken at the time of maturation were also analysed for Fe content. The correlation analysis between Fe contents of soil and Fe contents of leaf and grain was performed to determine the relationships among the variables. The Fe content of the soil samples collected in 2005 was between 2.60 and 6.00 mg kg-1. The Fe content of the soil samples collected in 2006 was between 6.96 and 12.70 mg kg-1. The iron content of the majority of soil samples, collected in 2005, was observed below the critical level which is 4.5 mg kg-1. The Fe content of the leaf samples was ranged from 69.50 to 156.70 mg kg-1 in 2005 and 138.10 to 518.10 mg kg-1 in 2006, whereas the iron content of the grain samples was ranged from 96.00 to 299.50 mg kg-1 in 2005 and 11.54 to 134.01 mg kg-1 in 2006. Also the Fe content of the leaf and grain samples was directly correlated with the Fe content of the soil. Correlation between iron content of soil and iron content of leaf in 2005 was significant at the 0.01 level according to statical analysis. While there was a direct relation between iron content of leaves and soil samples, there was an inverse relation between iron content of grain and iron content of leaf in 2006.
