Distichlis palmeri is an obligate emergent (it has aerenchyma) perennial rhizomatous dioecious halophytic C4 grass in the Poaceae (Gramineae) family. D. palmeri is a saltwater marsh grass endemic to the tidal marshes of the northern part of the Gulf of California and Islands section of the Sonoran Desert. [1] [2] [3] [4] D.palmeri is not drought tolerant. It does withstand surface drying between supra tidal events because roots extend downward to more than 1 meter (3 feet) where coastal substrata is still moist.

Culms (stalks) are generally rigid and upright to about 60 cm (2 feet) and have short internodes. Longer culms become recumbent (lay down) developing young vertical culms from the nodes. These young culms may root. Acicular to linear leaves are upright and positioned alternate along the culm at nodes. Leaves excrete salts through specialized salt glands that are a component of D. palmeri leaf anatomy. [5] [6] These excreted surface salts are wicked away by breezes. Insects of the grasshopper family visit the plant. When maintained in a greenhouse, it is susceptible to aphid infestation.

Anemophilous flowers emerge late winter. At anthesis, males liberate light chartreuse colored pollen in breezes. Female flowers are panicles of alternate spikelets that present lavender colored styles and stigmas. [1] [2] [3] Kernels (seeds) are mature in early spring. [3] Each panicle produces 20-30 mature caryopses. [3] Kernels are similar to those of farro in color and size. Kernels of Distichlis palmeri have an indigenous history as a wild harvest grain (Nipa) consumed by the Cocopah. Nipa grain has size, nutritional value and flavor qualities similar to other cropped grains. [2] [3] [7] [8] [9]

In the last four decades, Nipa grain production through saline agriculture (agriculture that uses saline resources to farm halophytic cash crops) of D. palmeri has been the subject of domestication studies. [2] [3] [4] [10] [9] [11] [12] [13] In addition to research studies working to domesticate D. palmeri, D. palmeri has been used to manage farm drainage and proposed as a constructive use plant in remediation of saline and biosaline wastewaters and land. [14] [15] [16]

Distichlis palmeri has character to thrive within effects of our changing climate; in open hot full sun on saline irrigation in subtropic zones, hence, it can be cropped along warming and rising coastlines [2] [3] [10] and is an active candidate for (bio)saline agriculture and cash crop development of Nipa grain, making it a prospective new crop for the 21st century.

Biosalinity is the study and practice of using saline (salty) water for irrigating agricultural crops.

Halotolerance is the adaptation of living organisms to conditions of high salinity. Halotolerant species tend to live in areas such as hypersaline lakes, coastal dunes, saline deserts, salt marshes, and inland salt seas and springs. Halophiles are organisms that live in highly saline environments, and require the salinity to survive, while halotolerant organisms can grow under saline conditions, but do not require elevated concentrations of salt for growth. Halophytes are salt-tolerant higher plants. Halotolerant microorganisms are of considerable biotechnological interest.

<span class="mw-page-title-main">Halophyte</span> Salt-tolerant plant

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'. Halophytes have different anatomy, physiology and biochemistry than glycophytes. An example of a halophyte is the salt marsh grass Spartina alterniflora. Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in the ehaloph database.

<span class="mw-page-title-main">Soil salinity</span> Salt content in the soil

Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. 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. It can also come about through artificial processes such as irrigation and road salt.

Salicornia bigelovii is a species of flowering plant in the family Amaranthaceae known by the common names dwarf saltwort and dwarf glasswort. It is native to coastal areas of the eastern and southern United States, Belize, and coastal Mexico. It is a plant of salt marshes, a halophyte which grows in saltwater. It is an annual herb producing an erect, branching stem which is jointed at many internodes. The fleshy, green to red stem can reach about 60 cm in height. The leaves are usually small plates, pairs of which are fused into a band around the stem. The inflorescence is a dense, sticklike spike of flowers. Each flower is made up of a fused pocket of sepals enclosing the stamens and stigmas, with no petals. The fruit is an utricle containing tiny, fuzzy seeds. The southern part of the species range is represented by the Petenes mangroves of the Yucatán, where it is a subdominant plant associate in the mangroves.

<span class="mw-page-title-main">Salt tolerance of crops</span>

Salt tolerance of crops is the maximum salt level a crop tolerates without losing its productivity while it is affected negatively at higher levels. The salt level is often taken as the soil salinity or the salinity of the irrigation water.

Crop tolerance to seawater is the ability of an agricultural crop to withstand the high salinity induced by irrigation with seawater, or a mixture of fresh water and seawater. There are crops that can grow on seawater and demonstration farms have shown the feasibility. The government of the Netherlands reports a breakthrough in food security as specific varieties of potatoes, carrots, red onions, white cabbage and broccoli appear to thrive if they are irrigated with salt water.

Dukhan Sabkha, located in the northern section of the Dukhan region in western Qatar, is the largest inland sabkha (salt-flat) ecosystem found in the Persian Gulf. The sabkha runs for approximately 20 km, occupies an area of 73 km², has a width of 2 to 4 km and a depth of between 6 and 7 meters below sea level. Consequently, the sabkha holds the distinction of accommodating the lowest point of Qatar. It is situated roughly 10 km east of the city of Dukhan and 2 km from Dukhan Highway. The Dukhan Field is to its immediate west.

<span class="mw-page-title-main">Biosaline agriculture</span> Production of crops in salt-rich conditions

Biosaline agriculture is the production and growth of plants in saline rich groundwater and/or soil. In water scarce locations, salinity poses a serious threat to agriculture due to its toxicity to most plants. Abiotic stressors such as salinity, extreme temperatures, and drought make plant growth difficult in many climate regions. Integration of biosaline solutions is becoming necessary in arid and semiarid climates where freshwater abundance is low and seawater is ample. Salt-tolerant plants that flourish in high-salinity conditions are called halophytes. Halophyte implementation has the potential to restore salt-rich environments, provide for global food demands, produce medicine and biofuels, and conserve fresh water.
