Abaxial epidermal strips removed from tissue cultured Chrysanthemum plantlets during the light or dark revealed open stomata and the guard cells contained starch.

Closure of the stomata was not induced by incubation of epidermal strips in darkness or by the presence of ABA.

Further stomatal opening was induced by CO2-free air and by kinetin. Following further opening using CO2- free air, the stomata could be induced to exhibit partial closure to their initial level of opening using ABA and darkness.
