Munch flow hypothesis
WebThe steady state solutions of two mathematical models are used to evaluate Münch's pressure-flow hypothesis of phloem translocation. The models assume a continuous active loading and unloading of translocate but differ in the site of loading and unloading and the route of water to the sieve tube. WebTwo crucial components of Münch's hypothesis, the translocation by mass flow from sources to sinks and the osmotic mechanism of pressure flow, were established notions …

Munch's Mass Flow Hypothesis is the theory which explains the flow of food materials through the phloem from the concentration regions to lower concentration regions. The force is needed to move organic food materials downwards in the phloem. This is caused due to differences in osmotic potential.
