ABSTRACT

Close parallels between transpiration and water deficit indicate that in diseased plants
water loss is largely determined by leaf water content. The rate of water loss
(transpiration) depends on evaporation. Therefore anything that affects the rate of
evaporation would also affect the rate of water lost.
There was no clear relationship between leaf growth rate and leaf water potential or
turgor for either species. It decreases with leaf age and is correlated with the rate of
dehydration, but it is independent of the tissues water potential.
