Abstract
A substantial enhancement of the width of stomatal aperture was produced by methyl viologen (MV) a Mehler reagent, in isolated epidermal strips from the leaves ofCommelina benghalensis L., andPisum sativum L., other Mehler reagents, flavin mononucleotide and anthraquinone were also found to stimulate the opening process. Histochemical tests have revealed a much greater influx of K+ into the guard cells in presence of MV. Isolated mesophyll chloroplasts possessed appreciable activity of MV-supported photophosphorylation and of oxygen uptake through Mehler reaction.
