The photosynthetic pigments were extracted from leaves and their parts using dimethyl sulphoxide; in given extracts, the quantity of these pigments was measured by spectrophotometer SF-2000. \u0000We determined general and specific peculiarities of the content of chlorophyll and carotenoids in the leaves of one- and two-year-old shoots of three forms of B. thunbergii during growth and heterogeneity of their quantity in differently coloured parts of the leaf blade of 'Coronita'. In the yellow margins of pink-coloured leaves of one-year-old shoots of “Coronita”, the content of green and yellow pigment was usually lower than in the peripheral part of purple-coloured leaves. The maximum content of both types of photosynthetic pigments in this part of leaves of one- and two-year-old shoots was noted in the first half of the growing season. The same applies to the middle parts of the pink- and purple-coloured leaves; the lowest content of the pigments is typical of hot and dry months. The yellow-green- and brown-coloured leaves of form 'Coronita' differ from the other two leaf types in that the content of chlorophyll and carotenoids is at the highest in the second half of the growing season, and it is significantly higher. The ratio of chlorophyll a/chlorophyll b in the leaves of three forms recorded in September-October increases in comparison with such ratio in May-July. It shows that, at the end of the growing season, catabolism of chlorophyll b takes place faster than one of chlorophyll a. With regard to the ratio chlorophyll/sum of carotenoids, this index decreases in autumn in comparison with the first half of the growing season; it shows that green pigments have more active catabolism than yellow ones. \u0000The maximum content of chlorophyll in the leaves of B. thunbergii is generally recorded in the first half of the growing season; this index decreases in the hot and dry second half, but when the heat drops, the quantity of carotenoids increases slightly. In this regard, variegated-leavf form 'Coronita' stands out; it is characterized by high endogenic variability in the content of pigments within leaf blades depending on the colouring of different parts of a leaf.","PeriodicalId":336963,"journal":{"name":"Scientific Issue Ternopil Volodymyr Hnatiuk National Pedagogical University.

MILL) of cv. Mashenka with a 0.3% aqueous solution of ethylene product on the yield and quality characteristics of berries, quantitative changes in the content of structural polysaccharides during ripening were studied. The experiments were carried out in the field from 2015 to 2017. The experimental sites were randomly chosen, there were five bushes in a row, the repetition of the field experiment was fivefold. The plants were treated with 0.3% aqueous esphone two weeks prior to berry harvesting using an OP-2 backpack. The berries under analysis were selected every four days after treatment with the preparation. The polysaccharide content was determined on a fixed material. The berries were fixed in the field with liquid nitrogen, dried in a drying oven at 70º C to air - dry state. The determination of cellulose and pectin content was carried out by weight method, hemicellulose and non-structural carbohydrates (sugars and starch) in gooseberry fruits were carried out by iodometric method. To evaluate the quality of the berries, their analysis for total acidity was performed by potentiometric titration, ascorbic acid was determined using potassium hexacyanoferrate. The analytical replicability of the studies is fivefold. Statistical processing of the results was performed using the computer program ‘Statistica-6’. The significance of the difference between the control and experiment indicators was determined by Student's t-test. It is found out that on the fourth, eighth and twelfth days, the content of reducing sugars, sucrose and their amounts in the berries treated with ethyleneproducer plants was higher than in the control sample. A more intense decrease in the total acidity of the berries of the experimental sample was observed, while the ascorbic acid content did not change significantly. A higher amylase activity in berries due to ethylene products during ripening was also established, resulting in a faster decrease in the starch content in the berries and an increase in the sugar content. Pre-harvesting of gooseberry with ethylene product esphone leads to increased accumulation of pectic substances in the products, a more intensive hydrolysis of structural polysaccharides in comparison with the control sample, which serves as an indicator of more intense maceration of fetal tissues. The use of pre-harvest processing of gooseberry with ethylene product esphone has led to increased yields and higher quality of gooseberry crop production and has many prospects for the development of mechanized harvesting technologies.","PeriodicalId":336963,"journal":{"name":"Scientific Issue Ternopil Volodymyr Hnatiuk National Pedagogical University.

These substances have a complex effect on growth and development and facilitate plant growth and crop capacity. \u0000Three-year field studies were carried out using plant growth regulators of Azotophyte, Amber acid and Vympel to determine the dynamics of plant growth rates and their productivity. This made it possible to observe the influence of growth regulators before sewing and to establish their effectiveness at all stages of plant development. Seeds of winter wheat of the variety Jubiwata were treated with solutions of the substances under analysis. The experimental area was 40 m². \u0000The study demonstrated that the growth regulators do not influence the field germination rate of plants, but the percentage of germination was quite high in both control and experimental variants. \u0000As for the rates of plant height and root length, the first measurement of the average height of winter wheat plants in autumn demonstrated that Vympel was the most efficient. Its indicators exceeded the control variant by 3.4%. After the second measurement, the plant height increased in all variants. The fourth spring measurement showed that the most powerful was the effect by Amber acid. This compound significantly inhibited plant growth compared to other growth regulators and controls. \u0000The investigated plant growth regulators have a positive influence on the processes of root development of winter wheat plants in both autumn and spring time. This feature will provide a better nutrition of the plants. \u0000The weight of the dry matter after the first weighing was greater in the control and the variant treated with Nitrogen. The fourth weighing showed that the best effect on the dry matter mass was found by Azotophyte, which contributed to the increase of this indicator twice as much compared to the control. Amber acid, when used for pre-sowing seed treatment, exceeded the control value by 1.8 times. \u0000Stronger effect on the percentage of dry matter in the plant sample was found only by Vympel, under the influence of which this indicator was greater by 9 units compared to the control. \u0000The use of synthetic growth regulators significantly increases the productivity of winter wheat, namely the length of the complex ear, the number of grains and the weight of the compound ear. \u0000Thus, research has shown that plant growth regulators Azotophit, Amber acid and Vympel facilitate the growth and productivity of winter wheat plants of the Juvivat variety. Winter wheat crops can be treated with these substances before sowing. Determining the highest efficiency of each individual regulator, as well as the possibility of combining them to improve plant growth processes, requires further research.","PeriodicalId":336963,"journal":{"name":"Scientific Issue Ternopil Volodymyr Hnatiuk National Pedagogical University.

The analysis draws on data on the structure of milk casein molecules as a complex globular micellar system, which is constructed by nanoscale sub-micelles, interconnected by calcium phosphate sites, with the formation of a casein-calcium phosphate complex. Sub-micelles differ in structure and function, according to which their four fractions are distinguished. The hydrophilic carboxyl groups of the glutamic, aspartic and orthophosphate acids of the κ-casein fraction provide the stabilization of casein micelles in the aqueous medium. Such structure of casein does not allow to receive film materials, they have low technological characteristics, very low durability and elasticity, high fragility. Moreover, they are easily soluble in water. \u0000Studies have shown that on the basis of casein it is possible to obtain polymer films, provided the use of a polymer composition, in which besides casein there is a modified polysaccharide. To obtain such a composition, carboxymethylcellulose was used, which also has biodegradable properties, however, unlike casein, it is capable of forming sufficiently strong polymer films. The polymer composition was synthesized in two steps: first, an aqueous solution of carboxymethyl cellulose was prepared, to which freshly precipitated casein with a moisture content of 20%, precipitated from skim milk, was added. The composition of the polymer composition was enriched with a number of additives serving as plasticizers, and structure-forming. The triatomic alcohol glycerol and diphenylamine were added as plasticizers too. In order to regulate the structure of the aqueous dispersion medium and prevent the processes of aggregation of casein micelles, calcium chloride solution was injected in the composition. The given polymer composition after polymerization in the air-drying process makes it possible to obtain sufficiently strong composite polymer films, the transparency of which depends on the type of plasticizer selected and the presence of CaCl2.","PeriodicalId":336963,"journal":{"name":"Scientific Issue Ternopil Volodymyr Hnatiuk National Pedagogical University.
