ABSTRACT
Pot culture studies were conducted to examine the effect of selenite (SeO3(2-)) and selenate (SeO4(2-)) on the uptake and translocation of root absorbed selenium in maize Zea mays plants grown in sand and soil culture. Increasing selenium supplementation (0.5-6.00 microg/ml), increased the selenium retention in roots, but there was little transfer of selenium from shoot to grains. The study indicates that selenite species (less mobile) also accumulates in maize plants when supplied in solution form. Selenium does not cause any adverse effect on the maize plants (dry matter yield vs concentration, no significant correlation, p>0.05).
