 note = {The present paper deals with studies on the vitamin B₁ content betweendiploid radishes (2n=18) and artificially induced tetraploid ones (2n=36), thevarieties used being Minowase and Miyashige. Vitamin B₁ was analysed by Permutit-Thiocrom method. (NISHIO,HUJIWARA, KITAMURA. 1946.) Power of assimilation was measured by Leaf-Punch method. The results were as follows. 1. The tetraploid radishes were superior in vitamin B₁ content to the diploid varieties. 2. The tetraploid radishes were superior in power of assimilation and water content to the diploid varieties. 3. Concerning the rate of variation-of vitamin B₁ content in the different organs in the same radish plant by polyploidy, the ratio of that in the root was .remarkably largar than that in the leaf., Article, 信州大學紀要. 第五輯, 農學部 1(1): 1-6(1951)},
