Effect of manganese on zinc-65 absorption by rice seedlings and its translocation within the plants

Summary Effect of manganese on absorption and translocation of zinc by rice seedlings was studied in a nutrient solution using radioactive zinc (Zn⁶⁵). With increase in manganese application, zinc uptake decreased in roots, but increased in shoots with an application upto 10 M manganese. Reduction in zinc absorption was more at low rates of zinc application. However, translocation of zinc from roots to shoots increased with manganese application upto 20 M but the increase was more pronounced with an application of 2M zinc only.
