Abscisic acid (ABA) causes the closure of stomata. By means of an infrared gas analyzer it was found that changes in the physiological status of Fragaria grandiflora Duch. cv. Red gauntlet, caused by pretreatment with exogenous ABA, decreased the sensitivity to the next dose of the hormone. A similar decrease of sensitivity to ABA may be obtained by shortening the light period. It is proposed that this decrease in sensitivity to ABA may be due to adaptation of guard cells to an excess of ABA.
