Abstract

Salinity is an escalating problem in agriculture worldwide (Szabolics, 1989; Hamdy, 1996; Choukr-Allah, 1996). The use of recycled and saline waters to replace fresh water in agriculture contributes, among other factors, to the aggravation of salinity problems. Most crop plants are sensitive to salinity and poorly equipped to cope with salt stress without suffering from impaired growth and development, and even injury (Läuchli and Epstein, 1990; Maas, 1990). The adverse effects of salinity cause considerable reduction in yields, far below the economic threshold of most crops in present use. It can be stated quite confidently that the prevalent future environment of agricultural crops will be much more saline than today. Therefore, improving salt resistance of crop plants is of major interest in agricultural research. Halophytes are the ultimate candidates to serve as a genetic source for this purpose.
