SUMMARY The application of farnesol to isolated epidermis of Commelina causes stomatal closure and death of guard cells. Experiments are reported in which the toxic effects were reduced by manipulation of the assay conditions. Reversible stomatal closure by farnesol was observed in intact plants. These results are discussed in relation to similar physiological effects in Sorghum and the possible role of farnesol as an endogenous antitranspirant.
