Biochemical Mechanisms of Salt Tolerance in Plants: A Review

Effects of Salt Stress on Plant Growth, Nutrient Partitioning, Chlorophyll Content, Leaf Relative Water Content, Accumulation of Osmolytes and Antioxidant Compounds in Pepper (Capsicum annuum L.) Cultivars

“…The interaction cultivar x salt treatment was significant for SDW and SL (Table 1). The reduction of growth parameters in salt sensitive 'Goliath' is a consequence of several physiological responses including modification of ion balance, mineral nutrition, stomatal behaviour and photosynthetic efficiency (Hosseini and Thengane, 2007;Li et al, 2008;Mudgal et al, 2010). This is consistent with the reports that NaCl reduces the ability of the plant to take up water, and this leads to slow growth; then when excessive amounts of salt entering the transpiration stream will eventually injure cells in the transpiring leave and this may further reduce growth (Munns, 2002).…”

Applying hyperspectral imaging to explore natural plant diversity towards improving salt stress tolerance

“…The salinity represents the harsh environmental stress limiting crop production on~20% of irrigated land worldwide (Mudgal et al, 2010). In arid and semi-arid areas, the irrigation is often used to compensate the lack of rainfall in drought prone regions; however, the intensive long-term irrigation of arable lands tends to increase salinity of soil to the extent which is unacceptable for crop plants (Flowers, 2004;Tang et al, 2015).…”

“…In order to survive in soils with a high salt concentration, plants improve different physiological and biochemical mechanisms (Mudgal et al, 2010). The most important mechanisms include, but are not limited to, uptake and transport of ions, ion homeostasis and compartmentalization, biosynthesis of osmoprotectants, synthesis of polyamines, generation of nitric oxide (NO), modulation of hormones, synthesis of antioxidant compounds and activation of antioxidant enzymes.…”

Physiological Behavior of Potato cv. Tollocan at Diverse Types of Salinity

“…This certainly causes losses for producers in these regions, who are forced to open new lands for cultivation. We therefore consider that these results are important for advisors and producers of potato in Mexico, to conduct monitoring of soil and water salinity and detect EC greater than 3 dS m -1 in soil solution and before potato planting, should proceed to implement saline control techniques such as: a) the use of irrigation water with low salt concentration, b) the establishment of artificial drainage, c) application of hydrochemical methods like salt lixiviation and chemical enhancers, and d) grow potato varieties of some tolerance to salinity as proposed by Levy and Veilleux (2007) and Mudgal et al (2010). From these results we conclude that: (1) High levels of salinity reduce the partitioning of assimilates to the tubers.…”

“…The objective of this study was to evaluate the biomass accumulation in this potato variety under salinity conditions that simulate those prevailing in soils of some semi-arid valleys sown with potato in Mexico, and determine their tolerance to salinity conditions. The theoretical and practical implications of this study may be useful to potato growers, to make timely decisions on the use of irrigation water in a certain salt concentration, and in the application of hydrochemical methods such as salt lixiviation, establishment of artificial drainage or applying agricultural chemicals such as gypsum and elemental sulphur (Sánchez, Ortega, Sandoval, Viruel, & Estrada, 2012) and breeding potato varieties for salt tolerance (Mudgal, Madaan, & Mudgal, 2010). These alternative techniques suggest that it is possible to control this abiotic factor and generate less adverse conditions for growth and development of the potato variety analyzed.…”
