Does anyone know whether or not Cytokinin is really used in the Opening and closing of the Stomata in plants? Or does it still remain just a theory?
Jun ('06): actually, no, cytokinins aren't involved in stomatal openings etc. stomatal openings etc are controlled by abscisic acid, which is part of potassium chloride threory, where abscisic acid causes the movement of potassium ions into the guard cells, drawing water into it via osmosis.
Matt ('06): Listen to Jun. He knows his stuff. =D
