Evidence is presented that the sensitivity of stomata to abscisic acid is greatly influenced by two factors which are known to vary in leaves, namely concentrations of potassium and of indol-3-ylacetic acid.

It is suggested that the notion of ‘quantitative tissue sensitivity’, by which Trewavas explains the action of growth substances in developmental phenomena, may be applicable to stomatal responses to abscisic acid.
