Salinity Tolerance: Growth, Mineral Nutrients, and Roles of Organic Osmolytes, Case of Lygeum spartum L., A Review
Soil salinity is a major environmental problem that limits plant growth, productivity, and survival. Proper drainage and the application of high quality water can although solve the problem; however, these measures are very costly and cannot be applied in extensive agriculture. An alternative strategy for sustainable agriculture in saline marginal lands is to select plants that can tolerate salinity. The plant’s ability to tolerate salinity depends on multiple biochemical pathways that enable retention and/or acquisition of water, protect photosynthetic functions, and maintain homeostasis of ions. Lygeum spartum L. is a pioneer grass species, used for sand dune fixation, desalination, and rehabilitation of degraded arid lands. The plant tolerates abiotic constraints such as salinity and drought and is also used to provide standing feed browse for livestock. The present paper reviews L. spartum plant responses to salinity stress with emphasis on the biochemical and physiological mechanisms of salt tolerance.
