Seedlings of pabby rice plants of varieties Norin No. 1, Shingyoku anb Kamezi, barley plants of Kingyoku anb Kobinkatagi, anb wheat plants of No. 50, Norin No. 69, and Saitama No. 27, all grown on soil were transplanted at the stage of growth with three tillers into test tubes eontaining solutions of the concentration of 10^-^2, 10^-^3, 10^-^4 anb 10^-^5 normals of iron anb aluminum ion. The varieties having small value of critical reaction in epidermal protoplasm of roots showed great resistance to toxic action of high concentration of iron and aluminum ions. But those having larger values were weaker. Low concentration of iron anb aluminium ions always promoted the growth of the plants. The concentration to promote the growth varied according to the plant and the variety. The growth of the shoot of Norin No. 50 and Norin No. 69 of wheat plant was accelerated in the 10^-^4 and 10^-^5 normal solution, of iron, while all other varieties were subjected to the toxic action. The growth of the root of all varieties, on the other hand, was subjected to toxic action whenever they were cultured in the 10^-^5 normal solution of iron. When aluminium was used, the growth of top and root of Norin No. 69 of wheat was promoted in the 10^-^3 normal solution, whereas Saitama No. 27 of wheat was equally promoted in 10^-^4 normal solution. Norin No. 50 of wheat showed intermediate response, being promoted in both of those solutions. The bariey varieties Kingyoku anb Kobinkatagi were slightly promoted in growth in the 10^-^5 normal solution.
