 note = {Sand culture using radish (Raphanus sativus L.) and hydroponics using carrot (Daucus carota L.) were conducted to examine root-uptake of carbon and its assimilation in the form of C-14-acetic acid. Radishes were grown under the dark conditions or the light conditions for 24 h. Carrot were grown under the light conditions after C-14-acetic acid addition. The C-14 radioactivity in each plant part was determined. The distribution of C-14 in the plants was visualized using autoradiography. The results indicated that the root vegetables absorbed C-14 through the roots and assimilated it into the shoots and edible parts. However, the amount of C-14-acetic acid absorbed by plants through the roots was considered to be very small. Absorption and assimilation of C-14 seemed to be carried out not because of uptake of C-14-acetic acid but because of uptake of C-14 in inorganic forms with very low concentration. C-14 dominantly transferred to the plant parts where were physiologically active., International Conference on Radioecology & Environmental Radioactivity},
