A halophyte is a plant that grows in 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. An example of a halophyte is the salt marsh grass Spartina alterniflora (smooth cordgrass). Relatively few plant species are halophytes—perhaps only 2% of all plant species.
The large majority of plant species are glycophytes, which are not salt-tolerant and are damaged fairly easily by high salinity.
One quantitative measure of salt tolerance (halotolerance) is the total dissolved solids in irrigation water that a plant can tolerate. Seawater typically contains 40 grams per litre (g/l) of dissolved salts (mostly sodium chloride). Beans and rice can tolerate about 1–3 g/l, and are considered glycophytes (as are most crop plants). At the other extreme, Salicornia bigelovii (dwarf glasswort) grows well at 70 g/l of dissolved solids, and is a promising halophyte for use as a crop. Plants such as barley (Hordeum vulgare) and the date palm (Phoenix dactylifera) can tolerate about 5 g/l, and can be considered as marginal halophytes.

For thousands of years, farmers have bred plants to produce desired characteristics. Now, scientists at the King Abdullah University of Science and Technology (KAUST) are working to develop new varieties of plants which can grow in extreme conditions. In this video, KAUST professor Mark Tester explains how new salt-tolerant and heat-resistant strands of tomatoes and quinoa can open new possibilities for food production.
Northern Chile Desert (200mm annual rainfall). Productivity ranging annualised yields around 5-10 oven dry tons per hectare (each year). Double purpose plantation (food and firewood). Marginal lands producing social and environmental goods.
