Aspekte demographischer Kernvariablen,ng areas where arid and semi-arid climates exist. The great majority of these areas appear to have been affected by excess soluble salts for thousands of years, but there is a very large area of land which has become saline within the period of recorded history. Secondary salinity is a great environmental problem faced by man today.

Biology and biogeography of halophytic species and salinity controlled ecosystemsder saline conditions. Great variations have come to our knowledge in the plant world with regard to responses to salinity. Various adaptive mechanisms have appeared in halophytes during the course of evolution. These include the elucidation of structural and functional adaptations which enable thes

Ecological and ecophysiological problemsof 103 countries totaled 203 million hectares (Anonymous, 1970). In general it can be concluded that salinity problems are found in all countries having areas where arid and semi-arid climates exist.

Germination ecology of halophytesn the life cycle will be exposed to. Laboratory investigations of seed germination indicate that seeds of most halophytic species reach their maximum germination in distilled water (Seneca, 1969; Onnis and Bellettato, 1972; Breen et al. 1977; Okusanya, 1977; Ungar, 1977a, 1978a; Zid and Boukhris, 19

Senescence in mangroves and/or withering. Perennials are capable of shedding several of their vegetative parts (branches, leaves, roots, etc.) or reproductive parts (flowers, inflorescences, fruits, etc.) through abscission. During the last two decades a great deal of time and effort has been expended in attempts to unrav
