The peculiarities of ice-forming in the stems of 7 cultivars and forms of blackberry have been determined by means of the differential thermal analysis. The authors have established the possibility of controlling the acclimation and loss of frost- resistance by tissues caused by dehydration. The control is possible on the basis of the data about exothermal processes in the tissues.

Мета. Встановити ефективність методів контролювання чисельності бур’янів стосовно продуктивності сорго звичайного двокольорового та соризу в умовах нестійкого зволоження західної частини Лісостепу України. Методи. Під час проведення дослідів використовували польовий, лабораторний і математично-статистичний методи. Так, польовий полягає у вивченні біологічних та екологічних особливостей росту, продуктивності та якості культури, включає спостереження, дотримання обліків умов і результатів. Метою лабораторного методу є виявлення взаємозв’язку між рослиною та середовищем (ґрунтом) способом їх аналізу. Математично-статистичний метод використовують для опрацювання експериментальних даних, щоб підвищити обґрунтованість результатів. Результати. За роки проведення досліджень проаналізовано видовий і кількісний склад бур’янів у посівах сорго звичайного двокольорового та соризу. Найвищу ефективність знищення бур’янів відмічено у варіанті з ручним прополюванням – 95,0–97,0%, за хімічного обробітку – 82,0–83,0%, за механічного – 78,6–88,5%. У контрольному варіанті (без догляду) забур’яненість, навпаки, збільшилась на 10,3–13,9%. Найнижчу врожайність зерна та біомаси у сортів ‘Дніпровський 39’ (2,35 і 22,23 т/га) та ‘Самаран 6’ (2,50 і 22,7 т/га) отримано на забур’яненому варіанті (контроль). Дещо вищу – за механічного обробітку. Застосування хімічного способу контролювання сприяло збільшенню кількості врожаю до 3,40 т/га зерна і 29,07 т/га біомаси у сорго та 2,80 т/га зерна і 27,73 т/га біомаси в соризу; ручне прополювання – до 3,90 т/га зерна і 32,13 т/га біомаси у сорго та 3,50 т/га зерна і 30,63 т/га біомаси в соризу. Висновки. Найбільший розрахунковий вихід біоетанолу та твердого біопалива з одиниці площі отримано завдяки ручному прополюванню у процесі вирощування сорго звичайного двокольорового (1,29 та 9,16 т/га) й соризу (1,16 та 9,09 т/га). Загальний вихід енергії становив 181,62 та 177,02 ГДж/га відповідно. В інших варіантах досліду вказані показники були нижчими. Кореляційно-регресійний аналіз даних показав сильну кореляцію між урожайністю зерна та виходом біоетанолу, врожайністю та виходом твердого біопалива, врожайністю зерна та виходом енергії з біоетанолу, врожайністю біомаси та виходом енергії з твердого біопалива. Коефіцієнт кореляції мав значення від 0,87 до 0,99, а коефіцієнт детермінації – від 0,78 до 0,99. | Purpose. To establish the effectiveness of methods of controlling the number of weeds on the energy productivity of sorghum and soryz in the conditions of unstable moisture in the western part of the forest­steppe of Ukraine. Methods. Field, laboratory, mathematical and statistical methods were used in the experiments. Thus, field research consists of studying the biological and ecological characteristics of growth, productivity and quality of the crop, including observation, recording of conditions and results. The purpose of the laboratory method is to identify the relationship between the plant and the environment (soil) through their analysis. Mathematical and statistical methods are used to process experimental data in order to increase the validity of the results. Results. Over the years of research, the species and quantitative composition of weeds in crops of sorghum and soryz was established. The highest efficiency of weed control was observed in the variant with manual wee­ding – 95.0–97.0%, with chemical treatment – 82.0–83.0%, with mechanical treatment – 78.6–88.5%. On the other hand, in the control variant (no maintenance), weediness increased by 10.3–13.9%. The lowest grain and biomass yields in the varieties ‘Dniprovskyi 39’ (2.35 and 22.23 t/ha) and ‘Samaran 6’ (2.50 and 22.7 t/ha) were obtained in the weeded variant (control); slightly higher for the mechanical treatment. The use of a chemical control method helped to increase the yield to 3.40 t/ha of grain and 29.07 t/ha of biomass in sorghum and 2.80 t/ha of grain and 27.73 t/ha of biomass in soryz; manual weeding – up to 3.90 t/ha of grain and 32.13 t/ha of biomass in sorghum and 3.50 t/ha of grain and 30.63 t/ha of biomass in soriz. Conclusions. The highest estimated yields of bioethanol and solid biofuel per unit area were obtained by manual weeding in the cultivation of sorghum  (1.29 and 9.16 t/ha) and soryz (1.16 and 9.09 t/ha). The total energy output was 181.62 and 177.02 GJ/ha respectively. In other versions of the experiment, the noted indicators were lower. Correlation regression analysis of the data showed a strong correlation between grain productivity and bioethanol output, solid biofuel yield and output, grain productivity and energy output from bioethanol, biomass yield and energy output from solid biofuel. The correlation coefficient ranged from 0.87 to 0.99 and the coefficient of determination ranged from 0.78 to 0.99.

Firstly in Ukraine as the result of resiprocal interbreedings of autotetraploid (2n=4x=32) / diploid (2n=2x=16) and diploid (2n=2x=16) / autotetraploid (2n=4x=32) four sintetic triploid (2n=3x=24) hybrid forms (611-91, 13-93, 14-93, 18-93) have been obtained. Spontaneous triploid nectarinum 166-80 has been shared out from diploid hybrid seedlings population. Tetraploid and triploid nectarinum forms are valuable sources for directoinal selection and making hybrids with the complex of new signs, which are difficult or impossible to receive on diploid level.
