A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs, and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'.
Mangroves are hardy shrubs and trees that thrive in salt water and have specialised adaptations so they can survive the volatile energies of intertidal zones along marine coasts. A mangrove is a shrub or tree that grows mainly in coastal saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal ...
Mangrove plants require a number of physiological adaptations to overcome the problems of low environmental oxygen levels, high salinity, and frequent tidal flooding.Each species has its own solutions to these problems; this may be the primary reason why, on some shorelines, mangrove tree species show distinct zonation.
Fields of scientific research relevant to halotolerance include biochemistry, molecular biology, cell biology, physiology, ecology, and genetics.. An understanding of halotolerance can be applicable to areas such as arid-zone agriculture, xeriscaping, aquaculture (of fish or algae), bioproduction of desirable compounds (such as phycobiliproteins or carotenoids) using seawater to support growth ...
The model for salt tolerance of crops stems from Riverside. [4] Saline and alkali soil conditions reduce the value and productivity of considerable areas of land in the United States. The problem is an old one, and there is much information on this subject in the technical literature.
Mangroves represent important nesting sites for numerous birds groups such as herons, storks, spoonbills, ibises, kingfishers, shorebirds and seabirds. Although often plagued with mosquitoes and other insects that make them unpleasant for humans, mangrove swamps are very important buffer zones between land and sea, and are a natural defense ...
Salt tolerance of crops is the maximum salt level a crop tolerates without losing its productivity while it is affected negatively at higher levels. The salt level is often taken as the soil salinity or the salinity of the irrigation water.
These include tolerance to conditions of high soil salinity, tolerance to submergence in water, or waterlogged soil, and to low oxygen conditions. The use of water to disperse young plants is also very characteristic of mangroves. [6] As a result of the water-logged soil that mangrove trees reside in, they have formed adaptations to help them ...
