THE RESULTS OF INTRODUCTION STUDY OF VILL. IN BOTANICAL GARDEN-INSTITUTE OF USC RAS

Abstract

The article presents the results of introduction study of A. narcissifolium in the conditions of the culture: long-term data on studying the seasonal rhythm of development, biomorphology, seed productivity, features of germination and biochemical structure are provided, and also the characteristic of age states is given (ontogenesis). Phenorhythmotype of species - long-vegetative, summer-autumn-green with compelled winter rest, late-summer-blossoming. Biometric parameters of A. narcissifolium : height of generative shoot averaged 71,4±1,05 cm, thickness - 0,6±0,02 cm, leaf length - 25,4±1,45 cm, width - 1,0±0,06 cm, diameter of umbrella - 5,7±0,06 cm, diameter of flower - 0,7±0,01 cm. In inflorescence there are 200 flowers, fruits - 181 pieces, fruit blossoming - 90 %, actual seed productivity - 416 pieces, number of seeds in fruit - 2,3 pieces, fruit semenification - 37,8 %, potential seed productivity - 1200 pieces, a productivity factor - 34 % are formed on average. In leaves it is revealed: 35,31 mg % of acidum ascorbinicum; 95,7 mg/kg of carotinum; 18,62 % of protein; 2,4 % of sugar; 4,56% of fat; 2,98 % of nitrogen; 1,8 % of amylum. From macrocells a potassium prevails, its quantity in an air-dried shot makes 2,77 %. A magnesium - 0,04 % which is the least in the content. From minerals iron is a leader, its content makes 90,9 mg/kg, the least one of all is cobalt - 0,13 mg/kg. The carried-out assessment of introduced stability of A. narcissifolium under the conditions of the culture on a complex of biologo-economic signs showed that A. narcissifolium was very perspective for cultivation in the region of the South Urals (score - 19).
