The behaviour of endogenous Mn2+ was studied by electron spin resonance spectroscopy during BA-induced growth of excised cucumber (cv. Long green) cotyledons. The level of endogenous Mn2+ was decreased by BA treatment, most pronouncedly after 96 h. MnCl2 applied alone promoted chlorophyll synthesis at relatively low concentrations but in the presence of BA higher concentrations of MnCl2 were required for stimulation of chlorophyll synthesis.
