Long before the scientific method was created, vine pruning was established as an art as early as at the beginning of the Christian era. Pruning is a way of reducing the vegetative part of the vine in order to limit its natural growth, and thus improve yield and grape quality by controlling the number of latent buds that are left per vine. Today, Virgilio and Plineo instructions are still being followed for pruning, with the exception of some small empirical changes, which were introduced in the 19th century by Jules Guyot. This report aims to evaluate the effect of pruning cuts on wood necrosis behaviour, and to determine the effect of pruning on shoot development on different vine varieties.

<p>Benzo[a]pyrene (BaP) is one of the most dangerous organic pollutants, a representative of the polycyclic aromatic hydrocarbons class, a carcinogen and mutagen of the I danger class. BaP content must be obligatory controlled in all natural environments. During BaP sorption on the soil surface, it is involving in the migration processes in the soil profile and the soil-plant system uptake. Plants are exposed to BaP, and almost 45% of the toxicant in the atmosphere could be accumulated by plants. The soil - plant system is an important object of the environmental pollution control, as it reveals the process of distribution, transformation, and accumulation of BaP in plants and soil. The aim of this work was to study the BaP accumulation in tomato plants (Solánum lycopérsicum) under the conditions of a model vegetation experiment.</p><p>The studies were carried out under the conditions of a vegetation experiment. The Haplic Chernozem soil was sifted through a sieve with a diameter of 1 mm and placed by 2 kg in 4 L pots. A BaP solution in acetonitrile was added to the soil surface based on the creation of a pollutant concentration in the soil of 400 μg kg<sup>-1</sup>. The original uncontaminated Haplic Chernozem was used as a control. The soil was sown with tomato plants (Solánum lycopérsicum) of the early maturing variety White filling 241. The experiment was replicated three times. The content of BaP in the soil of the control sample was 17.8 μg kg<sup>-1</sup>, in tomato roots - 2 μg kg<sup>-1</sup>, in the vegetative part of tomato - 1.0 μg kg<sup>-1</sup>, in the fruits of plants the value was equal to 0.3 μg kg<sup>-1</sup>.</p><p>Addition of the 400 μg kg-1 BaP increased it’s content in the soil to 369 μg kg-1. The accumulation of pollutant in the roots of the tomato plants was 244.5 μg kg-1, and in the stems and fruits it reached 130.2 and 55.1 μg kg-1, respectively, which greatly exceeded the control values. In the soil contaminated with BaP, the excess of the pollutant concentration relative to the control sample was 20 times. In the roots of tomato plants, the excess of the pollutant concentration relative to the control was 120 times, and in stems and fruits, the concentration excess relative to the control sample was 130 and 180 times, respectively.</p><p>Thus, there was an accumulation of the pollutant in tomato plants when the soil was contaminated with 400 μg kg<sup>-1</sup> BaP. The highest concentration of BaP was found for tomato roots and exceeded control content in more than 12 times. In plant stems, the concentration of BaP reached 130.2 μg kg<sup>-1</sup>, and in tomato vegetative part the concentration of BaP was 55.1 μg kg<sup>-1</sup>, which corresponds to 55 MPC for food products.</p><p>The research was financially supported by the Russian Science Foundation project no. 19-74-10046.</p>

The vegetative part of coniferous and deciduous wood plants is a unique source of natural compounds. The natural renewability of woody plants makes them an inexhaustible raw material for the production of biologically active substances. In the process of their production, about 70% of the non-recyclable post-extraction residue of the vegetative part remains, which is used as a feed additive. Since many plant wastes have a low protein content, in which essential amino acids are most often the limiting ones, they must be enriched with microbial protein, in particular the protein of basidial fungi. For this purpose, the fungi Fomitopsis pinicola (sw.) P. KARST (Fp5-15) were used in this work, since they are the least demanding to plant substrates and have high growth indicators. The purpose of this study was to study the amino acid composition of products obtained as a result of bioconversion of post-extraction residues of fir tree greens and the vegetative part of balsamic poplar (buds, litter). The analysis of the amino acid composition of the products showed that the protein score increases during the biodegradation process (phenylalanine and tyrosine-by 35 %, threonine – by 37.5%). Also, high amounts of glycine, alanine, histidine, aspartic acid, and glutamic acid were found in the products of biodegradation. In terms of the content of a number of amino acids, the resulting products are superior to cereals and feed products based on the vegetative part of woody plants. Thus, the results obtained show the possibility of using fermentation products as protein feed additives.

The purpose of this work was to assess the suitability of solid and liquid waste generated during processing of the vegetative part of poplar as substrates for biochemical processing in order to obtain biologics for various purposes. For the study, we used post-extraction residues, as well as a cubic liquid formed after distilling essential oils and extracting alcohol-soluble substances from the vegetative part of the balsamic poplar (Populus balzamifera L.). Siberian strains of fungi of the genus Trichoderma used as a biodestructor. Studies have shown that the vegetative part of poplar and its individual elements are an available substrate for the growth of mycelial fungi. The high yield of spores (4.5×109 spor/g) and the formation of humic substances (11%) used as plant growth stimulators during solid-phase cultivation of the MG-97 strain of Trichoderma fungi gives grounds to use the vegetative part of poplar as a technological raw material for obtaining a biological product of the "Trichodermin" type or soil humification. Depending on the purpose of the preparations, the duration of cultivation can vary: for obtaining agricultural biologics up to 15 days, more – for soil humification. The inclusion of a cubic liquid at the stage of substrate humidification allows to obtain a biological product with a higher spore titer (5×109 spor/g), makes it possible to close the water consumption cycle and make the technology of processing the vegetative part of poplar waste-free.

The purpose of this work was to evaluate the vegetative part of Jerusalem artichoke as a raw material for the production of cellulose using redox-organosolvent delignification in the medium "CH3СOOН – H2O2 – H2O". The chemical composition of the vegetative part of Jerusalem artichoke and the influence of technological parameters of the delignification process on the yield and properties of the cellulose product were studied. It was found that the vegetative part of Jerusalem artichoke collected in October (stems without leaves) with a chemical composition of more than 50 wt.% of polysaccharides in which presented the Kurshner-Hoffer cellulose more than 90 wt.% was more promising for processing. Experimental methods have been used to determine the parameters of the process of delignification of the vegetative part of Jerusalem artichoke, which provide a high yield of cellulose (42.1 wt.%) with a low content of residual lignin (1.1 wt.%): content of H2O2 – 6.5 wt.%, CH3COOH – 23.4 wt.%, GM 15, duration – 2.5 h, catalyst H2SO4 – 0.2 wt.%. It is shown that pre-extraction of the vegetative part of Jerusalem artichoke with a 0.3% solution of dicarboxylic acids at a temperature of 80 °C with a liquid modulus of 10 for 3 hours reduces the content of residual lignin in the cellulose product to 0.5 wt.% and obtain an extract whose yield is – 7.8 wt.%, including a PB of 4.2 wt.%, which makes it promising for biochemical processing. The obtained results expand the areas of use of the vegetative part of Jerusalem artichoke and show the prospects for further more depth research to optimize the process of delignification and study the properties of the cellulose product.

The article presents the results of a study of the impact of the enzyme complex strains M99-9 and K6-15 micro-peach fungi of the genus Trichoderma on a mixed substrate. It is established that in the process of biodegradation with strains K6-15 M99-9 in the substrate reduced content of extractives 2.1-2.4 times that of the polysaccharide is 1.5-1.8 times, and ligninase substances 1.2-1.4 times. This was an accumulation of up to 9-12% of humic substances. The decrease in the mass of the substrate during the cultivation of the strain M99-9 was 17.3%, and the strain K6 – 15-30% less. The most productive on this substrate is strain K6-15. The growth of conidia within two weeks of cultivation for strain K6-15 was 16.6·108 CFU/g and strain M99-9 – 11,5·108 CFU/g. High yield of spores and formation of humic substances during cultivation of fungi of the genus Trichoderma makes it possible to use the vegetative part of a poplar as raw materials for receiving a biological product “Trichodermin” or humification of the soil
