Webb7 apr. 2024 · In fact, many compounds of different metabolite families have been found, suggesting that phloem sap has metabolic functions beyond C, N and S redistribution from source leaves to sink organs. Nevertheless, it must be recognized that metabolites found in phloem sap depend on the analytical technique (typically, HPLC, GC-MS or LC-MS), and … WebbFör 1 dag sedan · The direction of mass flow from source to sink then changes to move nutrients to the aboveground organs [45]. Because the carbohydrate synthesized in the leaves cannot sustain the growth of the whole tree in April, when we collected the samples, the stem apex – which is the strongest sink at this stage – still required nutrients from …
