The disappearance of starch grains in the stems had been observed by several workers, when certain synthetic growth substances were applied to the parts of plants (1, 2, 3, 4) and consequently, it is supposed that the substances affected the translocation of carbohydrate. Quite recently a paper was presented by Zika (5), in which he reported about one hundred per cent increase of yield in potatoes after treatment of tubers with a-indoleacetic acid and therefore, the growth substance has been thought to be effective, not only for the translocation of carbohydrate, but also for its accumulation. Recently, just the same results were obtained by the authors in radishes and sweet potatoes after treatment of seeds and sprouts with certain growth substances, and the results will be given in this paper. Experiment 1. The seeds of two varieties of radishes, i. e. Horyo and Syogoin were soaked in the aqueous solutions of potassium j9indoleacetate and potassium a-naphtalenacetate in concentration of 0.02, 0.01, 0,005 and 0.0025% for 24 hours. Controls were kept simply put in ordinary water. The unwashed seeds were then planted on field on Aug. 20th, 1940. A retardation of development, as seen in the germination and growth of seedlings, combined with the swelling of cotyledons and hypocotyls, was seen after treatment with strong solution such as 0.02%, but the abnormality disappeared soon after. On December 1st, when all the plants were harvested and the wet weights of tops and roots were recorded per plant. The means of ten plants in each lot are given in Table 1.
