The karyotypes of Adonis amurensis from Amur Oblast,' and Adonis apennina from Altai Republic, Khakassia Republic, and Irkutsk Oblast' have been investigated. The karyotype formula was obtained as 2n = 2x =16 = 8m + 8sm(4sat) for all specimens. We estimated karyotype asymmetry through the calculation of the Coefficient of Variation of Chromosome Length (CVCL), Coefficient of Variation of Centromeric Index (CVCI), and Mean Centromeric Asymmetry (MCA), and determination of Stebbins asymmetry index. The chromosome set of Adonis amurensis was found to be more symmetrical than the chromosome set of Adonis apennina. The average absolute nuclear DNA content (2C–value) was originally determined for Adonis amurensis and Adonis apennina by flow cytometry and attained on average 20.38 pg and 17.29 pg, respectively.

The article presents the results of the analysis of the most relevant and promising technologies used in the digitalization of the state property management system in Russian practice. The relevance of the study is due to the rapid changes in the management practice of public administration in solving the problems of the public sector of the economy. The characteristics of the most relevant technologies of digital transformation of the state property management system are considered. The advantages of digital technologies applicable to the digitalization of this sphere are determined. The prospects of further use of the proposed methods of decision-making to improve the management system of state property are analyzed. It is established that the main technologies of digital transformation of the state property management system include smart contracts, artificial intelligence, big data and digital platforms.

The life form of Nitraria sibirica Pall. and the structure of its coenopopulation has been studied in natural conditions. Laboratory germination of seeds was investigated. Individuals build the life form of a hypogeogenic-geoxyle vegetative-mobile shrub. It is found that the coenopopulation is normal incomplete, the ontogenetic spectrum is of a centered type. The germination of seeds does not exceed 6 %.

Species composition of phytocoenoses of overburden dumps at Chernogorsky quarry has been investigated. Systematic, chorological, environmental and biomorphological analysis of flora has been carried out. It has been found that the quarry flora includes 47 species of higher vascular plants that are related to 35 genera and 16 families. 97.9 % are metasperms. Asteraceae and Poaceae are the largest families. Species with Holarctic areas prevail in the chorological structure (36.2 %). In terms of soil moisture all species can be subdivided into 3 groups: mesophytes (40.4 %), mesoxerophytes (36.2 %) and xerophytes (23.4 %). The leading role in the researched flora belongs to herbaceous polycarpous plants (57.4 %), which is characteristic of all the boreal region flora. 1 species listed in the Red Books of the Republic of Khakassia was discovered in the overburden dumps (Nitraria sibirica Pallas) and 6 species which have been noted for the first time for the flora of Khakassia. * Corresponding author: aes-1962@yandex.ru
