Abstract
The apparent rapid closure of stomata in response to the attachment of a porometer-cup, previously thought to be a shock-effect, is a misinterpretation. The porometer provides an accurate measure of stomatai aperture at the time of fixing, the subsequent "recovery" being an abnormally wide opening due to the reduction in CO2-content of the air within the cup, and not occurring elsewhere on the leaf. Superimposed on this is a true shock-effect of much smaller magnitude, probably due to shock-induced respiratory changes.This publication has 3 references indexed in Scilit:
