Biomass allocation is the end result of a number of processes which take place in the plant. It starts with the way how sugars are allocated over the different organs after having been fixed by the leaves in the process of photosynthesis (sugar allocation). Conceptually this is simple to envisage, but to quantify the flow of sugars is challenging and requires sophisticated machinery.
