      abstract     = {According to the Munch hypothesis, solution flow through
                      the phloem is driven by a hydrostatic pressure gradient. At
                      the source, a high hydrostatic pressure is generated in the
                      collection phloem by active loading of solutes, which causes
                      a concomitant passive flow of water, generating a high
                      turgor pressure. At the sink, solute unloading from the
                      phloem keeps the turgor pressure low, generating a
                      source-to-sink hydrostatic pressure gradient. Localised
                      changes in loading and unloading of solutes along the length
                      of the transport phloem can compensate for small, short-term
                      changes in phloem loading at the source, and thus, maintain
                      phloem flow to the sink tissue. We tested directly the
                      hydrostatic pressure regulation of the sieve tube by
                      relating changes in sieve tube hydrostatic pressure to
                      changes in solute flow through the sieve tube. A sudden
                      phloem blockage was induced ( by localised chilling of a
                      1-cm length of stem tissue) while sieve-tube-sap osmotic
                      pressure, sucrose concentration, hydrostatic pressure and
                      flow of recent photosynthate were observed in vivo both
                      upstream and downstream of the block. The results are
                      discussed in relation to the Munch hypothesis of solution
                      flow, sieve tube hydrostatic pressure regulation and the
                      mechanism behind the cold-block phenomenon.},
