摘要：

A new design of viscous flow porometer is described which is based on the pronciple of air suction into a syringe which then measures the volume of air atmosphere pressure. This porometer allows accurate readings to be made on the 0-100 scale on the syringe barrel when the piston has returned following its release. Each reading takes only seconds to make so that data can be collected for statistical analysis before stomata change in aperture and with minimal interference with the leaf envirnionment. Calibiration procedures are described: examples ofthe new porometers and also silicone rubber imprints support the validity of measurements made by the new porometer. © 1979 Oxford University Press.
