Root-uptake of 14C derived from acetic acid by root vegetables

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 14C-acetic acid. 14C-acetic acid (1, 2-14C, radioactivity: 74 kBq) was added to each pot. Radishes were grown under the dark conditions or the light conditions for 24 h. Carrot were grown under the light conditions af...
