Rosa sichotealinensis Kolesn., R. suavis Willd.Morphology and biology.
Deciduous shrub, 1.5 (2.5) m tall, with fulvous-brown shoots covered by numerous horizontally disposed thin thorns and bristles. Old branches are gray, with partially lost prickles. Leaves are alternate, compound, imparipinnate, 3-15 cm long, consisting of 5-7 (9) leaflets. Leaflets are 1.5-6 cm long, elliptic or oblong-ovate, sharp, thin, bluish-grayish, glandular-dentate or without glandules along the edge, naked from above, naked or pubescent (often only along the veins) from below. Stipules are glandular-ciliate along the edge. Pedicels are 0.7-3.5 cm long, varying from naked to glandular-pubescent. Sepals are lanceolate, broadened at the top, with smooth and glandular edges, remaining on the plant after the end of flowering. Flowers are singular or assembled in groups of 2-3 at the tips of branches. Corollas are dark-pink, 3-6 cm in diameter. The fruit is a multi-nut inside an effuse hypanthium, which becomes fleshy and forms the cover of a pseudocarp. Fruits are 15-20 (30) mm long, red, sometimes with bluish-gray bloom, variable in shape, with residual erect sepals.This species is entomophilous, ornito- and zoochore. It is propagated by seed and summer cuttings. Seeds should undergo stratification for 6-7 months at 3-5 degrees centigrade. Blossoms in June-July; fruits ripen in August-September. Chromosome number: 2n=14.Distribution.
Scandinavia, north and north-east of the European part of Russia, single locations occur in Volga region, the Urals, almost the entire territory of Siberia, Far East, northern Kazakhstan, Saur, Tarbagatai, Dzungarian Ala Tau, Mongolia, northern China, Korea, Japan and North America.Ecology.
This species has a wide ecological amplitude. It is a mesoxerophyte. It grows in forests and steppes, penetrates into high-altitude mountain areas and Arctic tundras. It occurs everywhere either as solitary plants or in small groups, less frequently forms almost pure brushwood or inhabits shrub communities as a subedificator. It inhabits undergrowth in various types of pinewoods, deciduous and mixed forests. In the southern parts of the area of distribution it more often grows in shady and damp habitats in birch forest outliers in steppe and river flood-lands. In the north part of the area of its distribution it avoids damp and cold soils and prefers exposures at the base of banks formed by lime stone, slate, marls and sandstones. Along river valleys and southern slopes, it penetrates into forest-tundra and tundra where it may be found among dwarf arctic birches. It ascends the mountains up to the lower part of the sub-alpine zone.Utilization and economic value.
This plant is used as a food, medicinal and ornamental. Fruits have a very high content of ascorbic acid and carotene. It is recommended for utilization in landscaping, being well adapted to pruning.References citations:
