Abstract

A method and apparatus were described for estimating the volume and mean pressure of gas in vapour phase in plant tissues, using a plot of volume versus reciprocal of pressure. This was achieved by using a pressure chamber in which the pressure was increased stepwise from 1.0 to 11.0 bar.
Volume of the gas space, which consists of compartments at various pressures, was partitioned by pressure, on the assumption that all the gas spaces dissolve completely at the same pressure.
This method revealed a peak of gas space at 1.3 bar (0.3 bar above atmospheric pressure) as well as at 1.0 bar in pericarp tissue of freshly picked cucumber fruit.
