Aeluropus litoralis (Gouan) Parl.

Local name:

  • Russian: Прибрежница солончаковая - pribrežnica solončakovaja
  • Uzbek, Kazakh: Azhrek
  • Turkmen: Zhurajrik, Chair

Chromosome number: 2n = 20 (Avdulov 1933; Litardiere 1950); 2n = 20, 30 (Tarnavschii 1948; Fedorov 1969).

Description and morphology: Perennial creeping grass (height 20–60 cm) with prostrate stems. Leaves: 2-row distributed, flat, rough with prickles, often with salt crystals on vegetative parts. Inflorescence: spikes assembled in panicle; spikelets naked, 5–10 flower clusters. Anthers ovate-oblong. Pollen grains 3-celled, orbiculate-oblong, monoporous. Ovule anatropous, crassi-nucellate, bitegmic.

Reproduction: Mainly vegetative (by rootstocks and rhizomes), rarely sexual. Anemophilous. Somatical apospory, nucellar and antipodal embryony. Flowering: April–June. Fruit maturation: end of July. Fruit: indehiscent, monosporous kernel, ovoid-lanceolate form, 3-edged (1.2–1.4 mm), light brown with hulled fruiting body assembled in flower and spike scales. Seed: well differentiated, erect embryo and endosperm. Dormancy B1 type. Viable seed: 67–80%. Light-sensitive. Germination (at variable temperatures): 38–74%. Short-term stratification at variable temperatures (5–10 °C/28 °C) effective. Seed longevity 8–9 years.

Pastoral value: One of the basic forages of saltmarshes in arid and semi-arid ranges. Well consumed by camels, cattle and horses all year round; used by sheep and goats in early autumn-winter. Expected yield on salt-crusted solonetz-alkaline soils is about 0.2 t DM/ha. On saline meadows and wet salt-marshes (solonchak-alkaline soils) yield is about 0.10–0.12 t DM/ha, and about 0.4 t DM/ha in favourable years. Used for haymaking and may yield up to 2–4 t DM/ha).

Fodder value: At flowering contains (% DM): crude protein 17; ash 13; cellulose 19; fat 2.9; nitrogen-free extract 39. At fruit stage contains (% DM): crude protein 9; ash 10; cellulose 31; fat 1.9; nitrogen-free extract 46. In seeds (% DM): protein 9; ash 10; cellulose 32; fat 2.6; nitrogen-free extract 51. Forage value about 31 FU and 1.7 kg digestible protein/100 kg DM.

Habitat: True halophyte. Hygrophyte. Occurs on salt-marshes (solonchak-alkaline) and crusty solonetz-alkaline soil in arid and semi-arid ranges, on lake shores, tugaï, saline deserts, depressions and takyr, growing in communities with species of Suaeda, Climacoptera, Tamarix, Phragmites and Salsola. Also found as a weed in salt-affected cultivated areas or waste ground. A good indicator of a high water table (depth 1–2 m).

Distribution: Middle Asia, southern Russia, West Siberia, Caucasus, Iran, India, China and Mediterranean region.
