Abstract: Dissociation constants and limiting molar conductivities of 2-styryl-3-R-benzothiazolium salts were determined in anhydrous ethanol. The values showed dependence on the character of substituent at the position 3 and on the nature of counter-ion. There was found a relationship between the magnitudes of dissociation constants and stimulation/inhibition activity on plant-growth.
