The rate of movement of materials in the sieve
elements can be expressed in two ways: as velocity, or as mass transfer rate.
In early publications reporting on rates of transport in the phloem, what is
the velocity and the mass transfer rate?
i)
velocity-centimeters per hour (cm h-1) and mass transfer- grams per
hour per square centimeter (g h-1 cm-2)
ii)
velocity-the linear distance traveled per unit time and mass transfer rate-the
quantity of material passing through a given cross section of phloem or sieve
elements per unit time.
iii) velocity- the
quantity of material passing through a given cross section of phloem or sieve
elements per unit time and mass transfer rate- the linear distance traveled per
unit time
iv) velocity- per hour per square centimeter (h-1 cm-2) and mass transfer- kg centimeters per hour (cm h-1)
