Large-petalled prince (Atragene macropetala)


Atragene macropetala (Ledeb.) Ledeb.

Category and status. 3 e. A rare species with a limited range, part of which is located in the Amur Region. Very decorative plant.

A brief description of. Perennial liana with a thin woody stem up to 2 m long. Flowers on long peduncles, large, with 4 oblong blue sepals up to 5 cm long., Soft-hairy on both sides. Petals are thinner, numerous, up to 5 cm long. Leaves on long petioles, twice triple or twice pinnately dissected into ovoid or oblong serrate or notched lobes, shiny below. Fruits - small narrow-wedge-shaped nuts with long pinnate columns. Flowering - May-June, fruiting - July-August (1-3).

Spread. In the Amur Region, the species was found in the Blagoveshchensk, Svobodnensky, Shimanovsky, Zeysky and Skovorodinsky districts in the Amur and Zeya valley in the lower reaches (3, 4). Outside the region in Russia, the plant grows in Siberia, outside the Russian Federation - in Northeast China and Korea (1, 2, 5).

Features of ecology and phytocenology. On stony slopes, on forest edges among shrubs, mainly in light coniferous forests.

Number. Approximately - 1 -5 thousand copies.

The state of local populations. The species is limited, it forms loose populations, the state and number of which depends on the growing conditions.

Limiting factors. Being at the limit of distribution, economic activity and human impact, fires. The species is confined mainly to the Zeya valley (to a lesser extent the Amur River), where the influence of economic activity (the creation of the Zeya hydroelectric complex, gold mining, etc.) is especially affected, and near the settlements there is a recreational load. These factors, especially the planned construction of the Gramatukhinskaya hydroelectric station, can lead to a sharp reduction in the number and number of populations, up to the complete destruction as a result of flooding of many habitats in the Zeya valley (6).

Security measures taken. The species is included in the regional summary of the Amur Region (3), found on the territory of the Zeysky Reserve, the Bekeldeul Zoological Reserve, the Annunciation Zoological Reserve, the Iversky Zoological Reserve, the Ust-Tygdinsky Zoological Reserve (4, 6,).

Necessary security measures. Identification of the general condition and number of species, monitoring. Giving the status of complex reserves to zoological reserves: Bekeldeul, Blagoveshchensky, Ust-Tygdinsky, on the territory of which, along with the prince coleoprotein, other rare red-book species grow.

Cultivation Capabilities. The plant is cultivated in many countries of the world; more than 30 varieties used in floriculture are developed on its basis (7). On the territory of the Russian Federation it is even found in the Polar-Alpine Botanical Garden on the Kola Peninsula, but its culture is more reliable south of St. Petersburg.

Eastern Siberia, the Far East, northeast of China and the north of Korea (forest edges, rocks, northern slopes)

in the Moscow region high

spring sowing requires 2-month stratification

• green and lignified cuttings,
• layering,
• dividing the bush,
• varieties - vaccinated

• in nature, spread along the ground and endure frosts up to -30 ° C without shelter,
• in the middle lane shoots lignified by a quarter of the length and can freeze, but are restored


They grow well on loose fertile neutral or slightly alkaline soils.

Responsive to moderate watering, but can not stand stagnant waters.

They prefer warm sunny places, but grow well with a little shading. The lower part of the plants is desirable to shade. For example, hosts that can be planted at a distance of 40-50 cm from the base of the vine.
