Water transport across peritrophic membranes of Calliphora erythrocephala—VII

Water ascent in tall trees: does evolution of land plants rely on a highly metastable state?

“…2 in his review article of 2002a) is a re‐invention of the pressure probe of Räde and Zimmermann and deserves, therefore, no further discussion. This also applies to the so‐called root pressure probe (Steudle & Jeschke, 1983; Steudle, 1993) that was adopted from Zimmermann & Mehlan (1976) and is used for measuring bulk water relations parameters of excised roots. This approach does not yield information at the single‐cell level and, due to the multi‐phase root compartment, interpretation of data obtained by the root pressure probe is based on many unproved assumptions.…”
