WebMar 1, 1982 · In C. borealis, there was small, but consistent translocation between sister ramets (0.2–4 per cent). Disturbance of unexposed sister ramets by defoliation, shading or herbivory increased the flow of photoassimilates to … WebPhotoassimilate and Phloem Transport (Carbon Compounds formed from Photosynthesis) Goals and Objectives: ... Be able to describe the source-sink concept and how it is involved in determining the direction and rate of translocation in the phloem.
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 ).
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 … WebIn botany, a photoassimilate is one of a number of biological compounds formed by assimilation using light-dependent reactions. This term is most commonly used to refer to …
WebNov 9, 2015 · The 11C-photoassimilate transport speed did not change over the two developmental stages. However, within a stem, transport speeds were reduced across nodes, likely due to higher 11C-photoassimilate unloading in the nodes. Photosynthesis in leaves and the amount of 11C that was exported to the rest of the plant decreased as …
WebPost-photosynthetic fractionation processes during translocation, storage and remobilization of photoassimilate are closely related to intra-annual sigma13C of tree rings, and understanding how these processes affect tree-ring sigma13C is therefore indispensable for improving the quality of climate reconstruction. inactivated vs unactivatedWebJan 30, 2014 · In general, however, the responses of translocation systems to increased CO 2 have yet to be documented.
