Yellow nutsedge (Cyperus esculentus L.) tuber maturity was studied to determine its influence on accumulation of 14C from urea and NAA (naphthaleneacetic acid). Radioactive carbon from the above sources accumulated in tubers in decreasing amounts as tubers became more mature when the plants to which they were attached were treated. Tubers that were young at treatment accumulated the highest concentration of radioactivity and parent tubers (most mature) accumulated the least 14C. Tubers that were classified as mature, but not parents, accumulated insignificant amounts of radioactive carbon.
