Abstract.The studies were conducted in 2015–2017 under conditions of the Novosibirsk region on grey forest soils. The purpose was to study morphology, phenotypic characteristics, the elemental and chemical composition of Miscanthus to assess the stability of the qualitative and quantitative indicators of the agrocenosis of the crop in the forest-steppe of the Novosibirsk Cis-Ob region. The object of the study was Soranovsky variety. Laboratory studies of the elemental composition of the plant parts were conducted using the Ginsburg’s method of wet combustion with subsequent determination of nitrogen and phosphorus by the spectrophotometrical method, determination of potassium on a flame photometer, and chemical composition using standard methods. The mass fraction of cellulose, acid-insoluble lignin, pentosans, fat-wax fraction, and ash content were determined by the Kuerschner’s method. M. sacchariflorus belongs to perennial grasses, which can reach up to 2.0–2.5 m in height. The long-rhizome structure of the underground shoot provided, in the absence of competition, rapid spreading of plants over a large area. The average nitrogen content in the roots and rhizomes of M. sacchariflorus was 0.77%; in the leaves, it was 1.6 times lower, but 1.6 times higher than in the stem. The amount of P2O5 in the leaves and underground organs was almost at the same level and averaged 0.12–0.13%, which was 1.5 times higher than in the stem. The K2O content in the leaves (0.47%) was 1.9 times lower than in the root system but 1.8 times higher than in the stem. Such an amount was enough for the formation of raw materials, in which the mass fraction of cellulose reached 52.9%, the mass fraction of lignin reached 24.5%, the mass fraction of ash reached 4.15%, the content of the fat-wax fraction was 2%. The climatic conditions of the Novosibirsk region were favourable for the development of the crop; Miscanthus sacchariflorus turned to be suitable for the production of high-quality cellulosic raw materials.
Keywords: Miscanthus; phenotypic characters; morphology; chemical composition.
