Web11 apr. 2024 · Study have demonstrated that sucrose, the main photoassimilates, is usually transported from leaves to sink organs, such as fruit (White et al. 2016). The phloem loading of sucrose at the leaves, long-distance delivery from leaves to sink organs, and unloading and metabolism in the sink organ are all important processes affecting final … WebSucrose, RFOs and polyols are transported in the sieve tubes to the sink organs in the transport phloem. All along the path, they can be leaked from and reloaded into the phloem via the same mechanism (not shown). Sucrose is unloaded into the release phloem where the hydrostatic pressure is supposed to be lower.
