Abstract: The effects of added methanol on the stomatal behavior of Vicia faba were tested.Methanol, methanol+6-benyladine (6-BA) and methanol+abscisic acid(ABA) were respectively applied to leaf pieces incubated in the light in bathing solutions.The results suggest that methanol elicit stomatal expansion under given concentration.The optimal concentration is 1.5% (ml/ml).Methanol has also synergism with 6-BA and antagonism against ABA.

Key words: Methanol, Vicia faba, Opening degree of stomata
