Salt tolerance of plants

01 Jan 1986-Vol. 1, Iss: 1, pp 12-25
TL;DR: In this article, the salt-tolerance data as well as tolerance limits for boron, chloride, and sodium are presented for woody crops, which are also influenced by specific salt constituents.
Abstract: Many plant, soil, water, and environmental factors interact to influence the salt tolerance of a plant. This chapter presents the salt-tolerance data as well as tolerance limits for boron, chloride, and sodium. Plant tolerance to salinity is usually appraised in one of three ways: the ability of a plant to survive on saline soils, the absolute plant growth or yield, and the relative growth or yield on saline soil compared with that on nonsaline soil. Temperature, relative humidity, and air pollution are important climatic factors that influence plant response to salinity. The salt tolerance of woody crops is complicated because they are also influenced by specific salt constituents. Crops irrigated by sprinkler systems are subject to additional salt damage when the foliage is directly wetted by saline water. Boron is an essential plant element but it can become toxic to some plants when soil-water concentrations exceed only slightly that required for optimum plant growth.

Abstract: Salinization is the accumulation of water-soluble salts in the soil solum or regolith to a level that impacts on agricultural production, environmental health, and economic welfare. Salt-affected soils occur in more than 100 countries of the world with a variety of extents, nature, and properties. No climatic zone in the world is free from salinization, although the general perception is focused on arid and semi-arid regions. Salinization is a complex process involving the movement of salts and water in soils during seasonal cycles and interactions with groundwater. While rainfall, aeolian deposits, mineral weathering, and stored salts are the sources of salts, surface and groundwaters can redistribute the accumulated salts and may also provide additional sources. Sodium salts dominate in many saline soils of the world, but salts of other cations such as calcium, magnesium, and iron are also found in specific locations. Different types of salinization with a prevalence of sodium salts affect about 30% of the land area in Australia. While more attention is given to groundwater-associated salinity and irrigation salinity, which affects about 16% of the agricultural area, recent investigations suggest that 67% of the agricultural area has a potential for "transient salinity", a type of non-groundwater-associated salinity. Agricultural soils in Australia, being predominantly sodic, accumulate salts under seasonal fluctuations and have multiple subsoil constraints such as alkalinity, acidity, sodicity, and toxic ions. This paper examines soil processes that dictate the exact edaphic environment upon which root functions depend and can help in research on plant improvement.
