Abstract
Through the use of a method involving the measurement of the rate of glucose-1-C14 and glucose-6-C14 oxidation, it was shown that while immature plant tissue respired glucose either exclusively or to a large extent via classical yeast glycolysis the participation of the direct oxidation pathway was increasingly pronounced as the tissue aged and differentiated, and in many mature tissues accounted for at least 50% of the respiration. The tissues used were root, stem, leaf, cotyledon, hypocotyl and coleoptile. Indoleacetic acid had no effect on pathway of glucose dissimilation by oat coleoptile.
