Studies on Oxidizing Power of Roots of Paddy Rice Plant (Part 1) : On Difference among Varieties of Seedling Roots

Abstract

The authors studied the difference of oxidizing power of seedling roots among thirteen varieties of paddy rice, water-cultured in glass room. Oxidizing power of roots were determined by the method based on precipitation of esculin. Thirteen varieties of paddy rice used were as follows : Norin No. 22,Norin No. 29,Norin No. 37,Mihonishiki, Aichi asahi, Chugoku No. 1,Habutae-mochi, Hokuchu No. 7,Tosan No. 41,Shiga asahi No. 20,Shiga asahi No. 27,Omi asahi, and Yubae. Results obtained were shown in Table 1.
