Abstract


Water relations, transpiration rate, stomatal behaviour and leaf sap pH of Aloe vera and Aloe eru Aloe vera L. and Aloe eru Berger, were grown in big pots (25 kg soil) under different irrigation regimes of fresh water, irrigation with brackish water, plants supplemented with Acacia saligna green manure and under direct and diffused sunlight. Aloe vera and Aloe eru are succulent CAM plants and exhibited a noticeably economic use of water by virtue of the Crassulacean acid metabolism rhythm, opening stomata by night and closing them by day, thus minimizing water loss. The leaf sap pH is acidic, acidity rose by night and declined by day. Structural adaptive characteristics, in addition to the functional CAM rhythm, are focused upon.
