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'.
High levels of salt entering the plant can trigger ionic imbalances which cause complications in respiration and photosynthesis, leading to reduced rates of growth, injury and death in severe cases. To be considered tolerant of saline conditions, the protoplast must show methods of balancing the toxic and osmotic effects of the increased salt ...
Biosaline agriculture is the production and growth of plants in saline rich groundwater and/or soil. [1] In water scarce locations, salinity poses a serious threat to agriculture due to its toxicity to most plants. [2] Abiotic stressors such as salinity, extreme temperatures, and drought make plant growth difficult in many climate regions. [2]
Crop tolerance to seawater – Crop tolerance to seawater is the ability of an agricultural crop to withstand the high salinity induced by irrigation with seawater. Halophyte – Salt-tolerant plant; Halotolerance – Adaptation to high salinity
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
High salinities occur in locations with high evaporation rates, such as in salt marshes and high intertidal pools. Shading by plants, especially in the salt marsh, can slow evaporation and thus ameliorate salinity stress. In addition, salt marsh plants tolerate high salinities by several physiological mechanisms, including excreting salt ...
Salinity is an ecological factor of considerable importance, influencing the types of organisms that live in a body of water. As well, salinity influences the kinds of plants that will grow either in a water body, or on land fed by a water (or by a groundwater). [19] A plant adapted to saline conditions is called a halophyte.
