http://facweb.furman.edu/~lthompson/bgy34/assimil.htm WebJun 4, 2024 · For growth of a plant to actually occur, the photo-assimilates synthesized in leaves must be exported to growing sink tissues. Up to 80% of fixed carbon is exported via phloem translocation in the day and night periods ( Grange, 1985; Geiger and Servaites, 1994; Lemoine et al., 2013 ).
