The Herbarium of SSU (SARAT) was founded in 1909; at present, significant material has been accumulated, which has not yet been fully processed. The Iridaceae family contains a number of species that are subject to protection, including at the federal level. It is quite large (more than 60 genera and 800 species distributed throughout the globe). According to the literature data on the territory of the south-east of Eastern Europe, where collections were carried out, stored in the herbarium of the Saratov State University named after N. G. Chernyshevsky (SARAT), two, possibly three genera are registered. According to the SSU herbarium (SARAT), 9 species belonging to 2 genera of the Iridaceae family were identified in the study area. As a result of the analysis, it turned out that 326 herbarium samples belonging to the studied family are stored in the SSU herbarium fund (SARAT). An analysis of the distribution of species was carried out according to two large summaries “Flora of the European part of the USSR”, and “Flora of the Lower Volga region” in accordance with the zoning adopted in them. As a result of the analysis of the collections of the SSU herbarium (SARAT) and the obtained field data, the range of the Iridaceae family was expanded, Iris arenaria, I. ruthenica, and I. sibirica are more widely distributed than previously thought. In addition, the question of the presence of I. ruthenica and I. tenuifolia in the studied region was considered based on our own field observations. There are no herbarium sheets for I. tenuifolia in the SSU herbarium (SARAT) confirming the presence of the species on the territory of the Saratov region. It is proposed to include I. ruthenica in the summary of the flora of the Saratov region and in the Red Book of the region, since this is the only locality of I. ruthenica in the region known to date.","PeriodicalId":14627,"journal":{"name":"Izvestiya of Saratov University.

We identified nine species of gamasid mites associated with nests of the common vole. For the first time, Laelaps algericus Hirst., 1925, was recorded for the fauna of the Dukhovnitsky district of the Saratov Region. We found two new to Saratov region genera of free-living mites (without species identification): Laelaspis A. Berlese, 1903 (Laelapidae) and Neoseiulus A. M. Hughes, 1948 (Phytoseiidae). The study has shown that facultative hematophages dominate numerically, and free-living forms predominate in terms of species composition. All hematophagous species found belong to the typical ectoparasites of the common vole, they have wide distribution and are common species for the fauna of the Saratov region.","PeriodicalId":14627,"journal":{"name":"Izvestiya of Saratov University.

We also discuss the effect of various factors on the process of MI-PANI synthesis, including polymerization methods, molecular weight of template molecules and the types of scaffolds. The analytical characteristics of the resulting sensors are also provided.

The study was conducted in 2007–2021. To identify the distribution, data from routine observations and information from herbarium specimens, literary data and oral reports were used. The determination of the abundance and density was carried out in all encountered cenopopulations (CP), and for a detailed description of structure, 23 CP were studied with the laying of more than 600 discount areas and with a description of more than 3600 individuals of the average generative state of the sweetvetch. It was revealed that all CP in study area occupy a total area of about 30.8 ha, on which there are at least 2.068 million individuals of the sweetvetch, of which about 1.305 million are generative. The average density of individuals ranges from 4.6 to 18.4, and of generative from 2.8 to 11.4 ind./m2. From the northeast to the southwest of the southern part of the Volga Upland, the number of individuals and the density of CP of the sweetvetch decrease, and the areas of CP decrease. The basic ontogenetic spectrum of CP in the study area is unimodal, centred, with a maximum at the mature generative state, but due to small temporal shifts of the ontogenetic spectra to the left, the type of dynamics of the age composition is fluctuating. CP are, as a rule, normal complete, transitional and mature, with an average level of vitality and are in a stable state. A comparison is made with data from other regions. The results obtained can be used in organizing and maintaining SPNR, compiling floristic lists, introducing and reintroducing H. grandiflorum and similar species, and selecting initial material when introduced into culture.","PeriodicalId":14627,"journal":{"name":"Izvestiya of Saratov University.

Biological testing of synthetic heterocyclic compounds – 4-arylidene-3-methylisoxazol-5-ones, which differ in nature, position and number of substituents in the aryl fragment, was carried out: 4-(4-methoxybenzylidene)-3-methylisoxazol-5-one, 4- (4-chlorobenzylidene)-3-methylisoxazol-5-one, 4-(4-dimethylaminobenzylidene)-3-methylisoxazol-5-one, 4-(4-hydroxy-3-methoxybenzylidene)- 3-methylisoxazol-5-one, 4-(3,4-dimethoxybenzylidene)-3-methylisoxazol-5-one. The compounds were obtained at the Department of Organic and Bioorganic Chemistry of the Saratov National Research State University named after N.G. Chernyshevsky in order to identify the relationship between structure and biological action. The paper presents the characteristics of the tested compounds and a modified method for the synthesis of arylidenisoxazolones. Seedlings of spring soft wheat Triticum aestivum L. cv. Saratovskaya 36 served as test objects. To assess the physiological activity of the tested compounds, we used the seed germination index, analysis of the morphometric data of the seedling, the root-to-shoot ratio and the root index. The inhibitory effect of some compounds on seed germination has been established. The most pronounced effect was manifested during seed germination in a solution of 4-(4-hydroxy-3-methoxybenzylidene)-3-methylisoxazol-5-one at a concentration of 10-7M. No significant effect of isoxazolone derivatives on the growth of the first leaf of the test object was found. All tested 4-arylidene-3-methylisoxazol- 5-ones had a stimulating effect on the growth of the root system in length. The direct nature of the dependence of this effect on the concentration of a solution of 4-(4-chlorobenzylidene)-3-methylisoxazol-5-one and 4-(3,4-dimethoxybenzylidene)-3-methylisoxazol-5-one was determined. A positive effect of the tested compounds on the root-to-shoot ratio of seedlings was revealed (with the exception of 4-(4-dimethylaminobenzylidene)- 3-methylisoxazol-5-one). The root index of seedlings was determined and it was found that the presence of methoxyl groups has an inhibitory effect on the value of this indicator. Based on the data obtained, it can be concluded that 4-(4-dimethylaminobenzylidene)-3-methylisoxazol-5-one and 4-(4-chlorobenzylidene)-3-methylisoxazol-5-one are promising compounds for further research.","PeriodicalId":14627,"journal":{"name":"Izvestiya of Saratov University.
