Abstract
The applanation system on air permeated screen () of this invention is a versatile instrument for measurement of tissue firmness generated by cell turgor pressure of leaves and organs segments with thin and elastic cell wall of several stalk, leaves, fruits and roots. It is composed by an air source with adjusted maximum flow (), a porous element () inserted on a screen (), by which air flows, and a device for compression application (). For measurements, the organ is progressively pressed against the screen until reversible interruption of the air flow crossing the porous element () is indicative of adequate applanation of the leaf against the screen. In this condition, one takes the firmness measurement reading as the applanation pressure (). This firmometer enables postharvest quality evaluation and measurements for ecophysiology studies and irrigation management procedure benchmarking.
