Occurrence of crassulacean acid metabolism in leaves of Aristolochia bracteata Ritz

Abstract

Aristolochia bracteata Ritz. is a common weed of fallowlands of hot, semi-arid region of Baramati area. High succulence index was noticed in leaf tissues along with marked diurnal fluctuations in titratable acidity status, and pH of leaf sap. Stomatal behaviour also followed typical CAM pattern. All these findings conclude that Crassulacean Acid Metabolism is in operation in this species.
