Abstract
The paper presents the results of the introduction study of A. libanii Boiss. in culture conditions: information is given on the study of the seasonal rhythm of development, biometric parameters, seed productivity, biochemical composition, breeding features, as well as a characteristic of age states (ontogenesis). The phenorhythmotype of the species is long-growing, summer-green with forced winter rest, medium-late-flowering. Bimetrichesky parameters: height of generative escape of A. libanii - 64.6±1.05 cm, its thickness - 0.6±0.02 cm, leaf length - 22.2±1.45 cm, its width - 0.9±0.05 cm, diameter of an umbrella - 5.0±0.06 cm, diameter of a flower - 1.0±0.01 cm. In an inflorescence of A. libanii there are on average 158.3±17.9 pieces of flowers, fruits - 125.3±19.4 pieces, the fruit formation of an umbrella makes 79.2 %. Real seed productivity per generative escape - 354.2 ± 40.62 pcs of seeds, potential seed productivity - 950 ± 69.53 pcs, umbrella productivity coefficient - 37.3%. The number of seeds in the fruit is 2.82 ± 0.06 pcs., The semenification of the fruit is 47.0%. The absolute weight of the seeds is 2.4 g. In the leaves revealed: 47.01 mg% ascorbic acid; 145.6 mg/kg carotene; 13.75% protein; 5.4% sugar; 4.55% fat; 3.36% nitrogen; 2.52% starch. Of the macroelements, potassium accumulation - 2.50%, calcium - 0.83%, phosphorus - 0.42%, magnesium - 0.10%, sulfur - 0.08%. Of the trace elements, iron accumulation is 103.7 mg/kg, zinc - 64.8 mg/kg, manganese - 36.6 mg/kg, copper - 6.0 mg/kg, cobalt - 0.25 mg. According to long-term phenological observations of A. libanii , winter-resistant, no damage was found by diseases and pests. In terms of points, it is assigned to the group of very promising plants (18 points).
