Morpho-biological features of rosewort(rhodiola rosea l.) under the conditions of introduction
Ural State Agrarian University, 620075, Karla Libknekhta str.,42, Yekaterinburg, Russia
The uncontrolled harvesting of rosewort has led to a sharp decline in its natural populations in the Nether-Polar Urals, and in a number of places in Altai and Sayany - to almost complete extermination of the plant. Nowadays rosewort is classified as rare and endangered species, in many regions - as a protected plant. One reliable way to preserve this plant is to introduce it into culture.
The article presents the results obtained during the experiment (during 2010-2014) on the study of morpho-biological features of rosewort(Rhodiolarosea) L.) under the conditions of introduction. Theexperimental design included 3 options, differing in the area of nutrition: 1 var. — 50 x 50 cm (4 plants/m2), taken for control; 2 var. — 33 x 50 cm (6 plants/m) 2. ); 3 var. - 25x50 cm (8 plants/ m2).
During the study, the optimal growing space was established - 50x50 cm, at which, during all years of observation, there was a more active growth of rosewort plants. Seasonal development process in all variants is represented by a single-vertex curve, with a pronounced maximum, the magnitude of which depended on the average daily growth of plants. The highest average daily increase in the experiment was observed in different terms: in the 1st var. — in the second decade of June; in the 2nd var. — in the third decade of June; in the 3rd var. — in the first decade of July; it varied from 1.28 cm (3 var.) to 1.71 cm (1 var.).
