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.Oligarchy 发表于 2025-3-25 13:25:38
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 thescardiac-arrest 发表于 2025-3-25 15:50:31
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. The great majority of these areas appear to have been affected by excess soluble salts for thousands提名的名单 发表于 2025-3-25 21:13:50

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, 19COLIC 发表于 2025-3-26 11:47:02
Aspects of salinity and water relations of Australian chenopodsant components of the shrub-steppe which occupy about six percent of the Australian land surface area of 4.34 x 10. km.. However, their contribution to pastoral production is much more than their share of the occupied area. Chenopod plant communities lie mainly south of the Tropic of Capricorn in a2否定 发表于 2025-3-26 13:10:20
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.
