Abstract: 
The distribution of Fe in chlorotic and healthy leaves of grapevine was studied. Application of HCO3- had no significant influence on the long distance transport of labeled Fe. The translocation of Fe from the vascular tissue to the intercostal cells (cells between leaf veins) was affected by HCO3-. Leaf samples collected from 3 different sites showed higher Fe contents in the chlorotic leaves as compared with healthy leaves. The solubility of leaf Fe in diluted HCl, however, was lower in chlorotic leaves than in green leaves. Enzymatic dissolution of leaves into vascular tissue, intercostal cells and chloroplasts revealed that the Fe-content in the intercostal cells of green leaves was significantly higher than in the intercostal cells of chlorotic leaves. The intercostal cells of chlorotic leaves had extremely high Ca and P-contents. The P content of green and chlorotic leaves was not related to the level of available P in the soil. The high P content in chlorotic leaves is the sequence and not the cause of Fe-chlorosis. On each of the 3 sites investigated, higher clay contents were found under chlorotic grapevine plants than under healthy ones. Because of this higher clay content, soil compaction may occur, resulting in an accumulation of CO2 and in an increase of the HCO3- concentration in the soil solution.
