Studies of Chenopodium album L. epidermal peels have shown that stomata respond to light and CO2 in a manner typical of other species. Thus, light and reduced CO2 concentrations were found to cause stomatal opening in the presence of 10−1 M KCl, whilst darkness and ambient CO2 caused closure in the absence of KCl. The herbicide bentazone (10−4 M) caused closed stomata to open in the absence of KCl, whilst KCl-stimulated opening was inhibited. Furthermore, closure of open stomata occurred in the presence of bentazone regardless of KCl availability. These findings are discussed in relation to the effects of other metabolic inhibitors on stomatal movement.
