ResumoAbstract Many instances of antagonistic relationships among various micro-elements and between micro- and macro-elements in their absorption, translocation, and functions in plant growth have been reported (1). In a series of our researches on the effect of micro-elements on the growth of rice plants, it was observed that manganese toxicity symptom of rice plants was markedly reduced by increasing the concentration of zinc in the nutrient sdution. Although it has been reported that manganese toxicity symptoms of crops were reduced by addition of Fe (2,3), A1 (4), Ca (5) and silicate (6) to the medium, there have been few reports of the effect of Zn on Mn toxicity of rice plants. In this paper, the interaction between Mn and Zn in the growth of rice plants was reported.
