Photoassimilate translocation
WebIn order to define translocation characteristics of 13 C-photoassimilates to fruit during the fruit development stage in 'Fuji' apple, the 13 C labeled tracer method was used in whole five-year-old 'Fuji'3/M26/Malus hupehensis (Pamp.) Rehder apple trees at different days after flowering (DAF). The changes in 13 C translocation to the fruit, source strength of the … Web2. Light Environment and Photoassimilate Translocation 2.1. Light Intensity Light intensity is a fundamental factor for translocation of photoassimilatesthe in plants. The export percentage of carbon from source leaves is stable, but the amount of carbon per unit leaf area mainly depends on the carbon pool [3].

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 ).
