SLEEPING SLEEP (S. PANICEA L.)

Sedge millet (S. panicea L.)

see also GENE OF SEDIMENT (CAREX L.)

Perennial with an arcuate rhizome 1.8–2 mm thick and usually not less than 10 cm long. The stalk is 10–40 cm high smooth, with brown scaly leaves and sheaths of the lower middle leaves at the base. The median leaves are bluish-green, 3-5 mm wide, obscurely two-folded, with papillae on the underside of the laminae, rough on the edge, gradually pointed. The inflorescence consists of 1 apical reddish male spikelet, 2-3 cm long and 1-2 female. Female spikelets are usually erect, with legs, sitting in the axils of covering leaves with a vagina about 1 cm long and a short leaf blade. The bracts of female flowers are brown-brown, on the back with a light or green strip, ovate, sharp, shorter than the sacs. Sacks about 4 mm long, ovoid, somewhat swollen, brownish-green, with small papillae and longitudinal veins, with a short nose slightly bent to the side. Stigma 3. Nuts 2-2.4 mm long, dark brown, with a light yellow nose 0.5-0.7 mm long (see Fig. 2-3).

Mostly European look. In the USSR, it is distributed in the northern half of the European part, in the Caucasus, southern Siberia, and Central Asia. It grows in moist and swampy meadows, lowland marshes, sparse forests. Mesohygrophyte. Avoid dry and waterlogged places. It prefers marshy, clayey, rarely sandy and sandy soils, from poor to rather rich, with a slightly acidic and neutral reaction. Demanding on light, does not withstand shading.

Often dominates in a grass stand with a white belly sticking out, red fescue, pike, often grows together with meadow-bog species. It does not form pure thickets.

Propagated vegetatively and by seed. Seeds without stratification have a low percentage of germination; after storage for 3 months, their germination is about 45%. The development of shoots is similar to the development of long-rhizome sedges, such as short-hairy sedges. Generative shoots are formed within 2-4 years. Up to 5 middle leaves develop on them annually; for 1 to 3 years, the shoots function as vegetative. The leaves are long - 25-30 cm. In generative shoots, the leaves do not exceed 2-5 cm in length. The shoots bloom in May, the fruits ripen in July. Generative buds are laid in the fall.

It is poorly eaten in the pasture, in the hay it is satisfactory. Productivity of meadows with the participation of this sedge is from 7 to 28 kg / ha. Contains protein 12.4% of absolutely dry matter, protein 9.8, fat 5.4, fiber 24.6, nitrogen-free extractive substances 52%. It does not have significant feed value.

Sedge millet - a perennial plant with horizontal underground rhizomes of 1.8-2 mm in diameter, consisting of 13-14 internodes and reaching between the tillering zones 15 cm in length. Tillering zones are composed of 5-6 internodes. The roots are light, about 0.8 mm in diameter and up to 20 cm long, slightly branched, laid mainly in the tillering zones of vegetative shoots. The lower scaly leaves are dirty brown or brown, decaying into fibers. Stems 10-40 cm long, smooth, trihedral. Shoots develop as dicyclic. From the mother originates 2-4 lateral extravaginal shoots.

Inflorescence of 1 male and 1-2 female erect oval spikelets located on the legs in the axils of the covering leaves with a sheath of about 10 mm in length and a short leaf blade. Male spikelets are cylindrical, 2-3 cm long, 3 mm in diameter, with oblong-lanceolate covering flakes. Covering scales of female flowers are ovoid, sharp, brown-brown, with a central light brown or green stripe, with a white border at the edges or without it.
