Abstract
Levels of Mg 2+ , Ca 2+ and Fe 2+ /Fe 3+ were determined in roots and shoots of sugar beet seedlings ( Beta vulgaris L. cv. Monohill) cultured for 5 weeks in a complete nutrient solution to which either Cd 2+ (0, 5 or 50 μ M ), EDTA (0, 10 or 100 μ M ) or a combination of both was added. The plants subjected to the various treatments showed a variety of deficiency symptoms. Leaves of the Cd 2+ ‐treated plants became thin and chlorotic (Mg‐ and Fe‐deficiency symptoms). The plants showed reduced growth and developed only a few brownish roots with short laterals (Ca‐deficiency symptoms). EDTA treatment resulted in green, stunted, hard leaves and reduced growth (Ca‐deficiency symptoms). The deficiency symptoms observed correspond well with the observed uptake rates and distributions of Mg 2+ , Ca 2+ and Fe 2+ /Fe 3+ . Increases in either Cd 2+ , EDTA or a combination of both in the growth medium, were correlated with increasing Mg 2+ levels in the roots and with decreasing Mg 2+ levels in the shoots. Cd 2+ alone or in combination with EDTA had little influence on Ca 2+ levels in the shoots but decreased Ca 2+ levels in the roots. Thus, Cd 2+ affects Mg 2+ and Ca 2+ transport in opposite ways: Mg 2+ transport to the shoots is inhibited while that of Ca 2+ is facilitated. Treatment with EDTA alone did not affect Ca 2+ concentrations in either the shoots or the roots. Treatment with Cd 2+ lowered Fe 2+ concentrations in both roots and shoots.
