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. Web2 mei 2012 · Hours later they detected [ 14 C]sucrose, accompanied by small amounts of [ 14 C]hexose, in the bark near the transport front. They concluded that sucrose is the transported sugar, whereas the small amount of radiolabelled hexose had been derived from [ 14 C]sucrose by hydrolysis. somatic psychotherapy today
