Abstract

Carrot (Daucus carota L. var. Imperator) seeds were planted in soil treated with amiben-C14 at 3 and 6 lb/A. Plants were harvested after 69, 103, and 191 days, autoradiographed or analyzed for the radioactivity in the 80 percent ethanol soluble fraction and in the insoluble fraction. The highest concentration of radioactivity was on or near the surface of the roots, but some radioactivity was present throughout the leaves and roots. The concentration of radioactivity decreased with time both in the soluble fraction and insoluble fraction of the root; in contrast it decreased in the insoluble fraction and increased in the soluble fraction of the leaves.

Disks of carrot root were placed in an aerated solution of amiben-C14. After 6 days, only 18.7 percent of the amiben remained unaltered. About 4 percent of the radioactivity was released as C14O2; 64.3 percent was present in an unknown compound which may contain a sugar moiety; the remaining 11.8 percent was distributed among four additional unknown compounds.
