Conteúdo: | Two experiments indicate that abscisic acid (ABA) may influence stomatal behaviour of Commelina communis L. Stomatal conductance could not be correlated with bulk leaf ABA content but when the abaxial epidermis was assayed for ABA, small increases in ABA content correlated well with limitations of leaf conductance. Restricted conductance of the abaxial surface of leaves was associated with an increase of approximately 40 amole ABA per stomatal complex. This agrees with previously published figures.
