The presence of a large amount of heavy metals in plants and soils used for growing agricultural crops constantly affects the environmental safety of the respective environment. An increase in the concentration of trace elements and compounds of heavy metals in plant tissues leads to disturbances in the metabolism of plant and animal organisms. Thus, long-term exposure to high concentrations of heavy metals and their compounds in soil and plants can cause pathological changes or disruption of biological processes. The analysis of the interaction of micro- and macronutrients with the carbohydrate components of chicory plant raw materials aims at the possible leveling of the negative impact of the formed complexes on the general ecological state of the environment. The non-destructive method of X-ray fluorescence analysis of biologically active compounds was used to conduct the research, which is the most accurate and effective from the point of view of the time of conducting the experiment. Derivatographic methods of research, or combined methods of thermal analysis, allow simultaneously to obtain data on the change in the mass of a substance and the speed of this change in an automatic mode, as well as to obtain the physical and chemical characteristics of such processes. The choice of traditional methods of analysis, in particular thin-layer chromatography, spectrophotometry, measurement of the polarization angle, electrophoresis, is determined by the relative simplicity and accuracy of the obtained data. The results of research conducted on the content of microelements and their interaction with carbohydrates of vegetable inulin-containing raw materials showed that the content of 20 macro- and microelements in chicory roots was determined by X-ray fluorescence analysis. The study confirmed the regularity of changes in the content of trace elements depending on heat treatment, in particular in harsh conditions. Based on the results of the research, it was established that the heat treatment of chicory roots, in particular their frying, significantly improves the mineral composition of this plant material. The developed method of non-destructive analysis of the content of mineral components in vegetable raw materials, which uses carbohydrates as a matrix for measurements, allows obtaining reliable results. It has been proven that the type of carbohydrate has almost no effect on the results of the analysis. Based on the obtained data, a series of standard samples was developed to determine the content of elements such as Cd, Zn, Pb and Hg, and the corresponding calibration curves were constructed. The derivatography study confirmed the formation of calcium and magnesium complexes with inulin, as well as the stabilization of saccharides when complexed with the mentioned elements and determines the further strategy for reducing the negative impact of these compounds on living organisms.

The main factors that have a great influence on plant growth, as well as on increasing the yield and its quality characteristics, are biotic and abiotic. Combinations of abiotic stresses, such as drought and heat, have a much greater impact on yields and product quality. The response of plants to these stresses can vary depending on the species, as well as at different stages of development. Understanding the mechanisms and how they protect plants from stress has become vital to improving the yield and quality of parsnip products in changing climatic conditions. The research aimed to study the influence of abiotic factors (temperature and precipitation) on yield, duration of phenological phases of plant growth and development, dynamics of growth of leaves and roots of parsnip in the Right Bank Forest-Steppe of Ukraine. The research was conducted in the field experiment of the Department of Vegetable Growing and Closed Soil in NL "Fruit and Vegetable Garden" NUBIP of Ukraine in the Right Bank Forest-Steppe of Ukraine during 2015-2017. The area of the accounting plot was 11.3 m2, the repetition of the experiment was 4 times. The arrangement of the research plots was systematic. As a result of research, it is established that the shortest period of sowing-seedlings lasted 16 days in the options for sowing in the 3rd decade of May and the 1st decade of June. Significant delay for 21 days of this period was observed for sowing from the 1st to the 3rd decade of April. The duration of the period from the beginning of root formation to beam ripeness was the smallest for sowing in the 1st decade of April – 28 days, and the largest for sowing in the 1st decade of June – 51 days. The vegetation period ranged from 110 to 165 days and passed for the sum of temperatures (> 10 °С) 1102.4-1439.0 °C and the sum of precipitation 128.1-225.2 mm. During sowing in April, an intensive increase in root crops from 2.9 to 3.5 g/day was observed in the second half of August. During sowing in May, the largest increase in root crops from 2.1 to 2.7 g/day was observed in the first half of September. Thus, for sowing in the 1st decade of June, this figure was highest in the second half of September (1.9 g/day). The option for sowing in the 1st decade of April provided a high yield of root crops of 50.3 t/ha, which is 5.3 t/ha or 11.8% significantly more than the control. When sowing in the following periods, a significant decrease in yield was observed compared to the control, namely: for the 3rd decade of April – by 3.5 t/ha, or 7.7%, for the 1st decade of May – by 8.8 t/ha, or 19.6%, for the 2nd decade of May – by 17.4 t/ha, or 38.6%, for the 3rd decade of May – by 23.0 t/ha, or 51.1%, for the 1st decade of June – by 31.7 t/ha, 70.6% compared to the control. There was a direct strong relationship (r = 0.74-0.99) between the growing season and yield, root weight, marketability, and biochemical parameters, namely: dry matter, dry soluble matter, sugars, vitamin C. The inverse of the strong (r = -0.98) was observed between the duration of the growing season and nitrates. Increasing the growing season by 10 days increases the yield to 6.9 t/ha, marketability up to 2.7%, root weight up to 31 g, dry matter content up to 0.7%, dry soluble matter up to 0.3%, sugars up to 0,5%, vitamin C to 0.8 mg/100 g and reduces the nitrate content to 8.4 mg/kg. Leaf area, photosynthetic potential, net photosynthesis productivity are in strong direct connection (r = 0.92-0.98) with yield. As the leaf surface area increases to 1.0 thousand m2/ha, the yield increases to 0.7 t/ha. Increasing the photosynthetic potential to 0.05 million m2 per day/ha increases the yield to 0.2-1.2 t/ha. Also, the yield increases to 0.3-0.7 t/ha by increasing the net productivity of photosynthesis to 0.05 g/m2 per day. Promising for further study is molecular knowledge of plant responses to abiotic stress, likely to pave the way for making crops resistant to climate change and increase the economic efficiency of production.

Parsnip is a valuable vegetable crop. Its roots are used in various sectors of the economy due to its rich chemical composition. But the area under the crop is insignifcant. Despite the signifcant number of scientifc publications, the issue of parsnip growth in the conditions of Transcarpathiahas not been explored. Therefore, the aim of our research was to study the processes of growth and development, yield and preservation of parsnip roots for cultivation in soil and climatic conditions of the foothills of Transcarpathia. When studying the phenology of varieties, it was noted that the period from the emergence of seedlings to the formation of a rosette of leaves was the shortest in the variety of Hungarian selection Felhosszu and lasted 31 days. The shortest interphase period "rosette formation – root formation", which lasted 41 days, was recorded on the variant with the variety of German selection Boris. The study of the biometric parameters of the rosette of parsnip leaves showed that its height and diameter are dominated by the Felhosszu variety – 69.8 and 38.4 cm, respectively. The number of leaves in the rosette (6.4 pcs.) was the maximum in the Borisvariety. The standard variety Petryk was distinguished by its length (26.8 cm), diameter (4.9 cm) and weight of root crops (158.8 g). This variety formed the highest yield – 56.7 t/ ha, within which 90.3 % were marketable products. The Boris variety formed a marketable harvest at the level of 45.9, and Felhosszu – 44.9 t/ha, which was 87.4 and 82.8 % of the total harvest, respectively. To study the best way to preserve products, we used three methods of storage: bulk in boxes, unwashed and washed in plastic bags. Maximum weight loss was observed during storage of root crops in bulk in boxes. They ranged from 6.2 to 6.7 %. The largest share of the mass was lost by the food organs of the German selection variety. But these losses in different storage methods were distributed unevenly over time. At the beginning of storage they were high enough, by January-February they sharply decreased, and further grew again. Among the methods of storing roots, the best one was to store them unwashed in plastic bags. In this way, the yield of marketable roots after long-term storage from late October to late May ranged from 92.8 to 93.6 % and was highest in the Petryk variety . This variety gave the highest yield of marketable roots and for their preservation in bulk in boxes and washed in plastic bags. Key words: parsnip, phenophases, biometric parameters, roots, yield, safety.
