Photo-oxidation of ascorbic acid in leaves

Abstract

These studies were planned as an extension of previous work (Mapson, 1961a) on investigations into the possible role of ascorbic acid and its oxidized forms as electron carriers in plant respiration, and the present investigation was also carried out with this object primarily in view. The results to be described in this paper suggest that the ascorbic acid system may function as an electron- transferring system during photosynthesis, in addition to any such role in respiration.
