A steady-state model of solution flow in a tubular semipermeable membrane is developed for an arbitrary distribution of solute sources and sinks along the translocation path. It is demonstrated that the volume-flow mechanism of phloem transport depends only on the two assumptions: 1. that the plasma

The sieve-tube sap of Ricinus communis L. seedlings has been analysed to determine whether or not hexoses can be taken up by the phloem. Under natural conditions, i.e. with the endosperm attached to the cotyledons, glucose and fructose occurred only in trace amounts in the sieve-tube sap. Incubation

Exudate can be obtained from incisions made in the bark of the stem of actively growing Ricinus plants, ltC-labelled assimilates from a fed leaf are rapidly detected in the exudate. This movement was both acropetal and basipetal from the fed leaf, at rates of over 100 cm h -1. Estimated rates within
