Abstract | The daily and yearly course of transpiration, water saturation deficit of plants, the course of the quotients: water content/ surface, water content/dry wt., the water content, movement of stomata, the yearly course of the osmotic values of the plants, suction pressure and water content of the soil were measured for a number of halophytes (Suaeda palaestina, S. fruticosa, S. monoica, Arthrocnemum glaucum, Tamarix tetragyna) and xeromorphic plants (Prosopis farcata, Alhagi maurorum, Nitraria retusa). The root system of the halosucculents is poorly developed, but Prosopis and Alhagi have very deep roots reaching the water table (15 m. and more). The osmotic values of the halosucculents are very high, of the xeromorphs relatively low. The water economy of Prosopis and Alhagi is a very wasting one, whereas the halosucculents are thrifty with their water. The high transpiration per unit of surface, (especially of Prosopis and Alhagi) is compensated by the development of a small transpiring surface and its additional reduction in the dry season. The facts observed do not corroborate Schimper's theory of the physiological drought of moist saline habitats. ABSTRACT AUTHORS: M. Evenari |
