Изучено влияние физиологически активных веществ Гиббереллина, Циркона и Эпин-экстра на механический состав грозди, урожайность и содержание сахаров в соке ягод трех столовых сортов винограда в условиях Приднестровья. Определено влияние физиологически активных веществ на изменение массы грозди, количества ягод в грозди и урожайности в зависимости от метеорологических условий года. Установлено, что в более влажных условиях 2019 г. (ГТК = 1,0) увеличение массы грозди в опытных вариантах в сравнении с контрольными растениями составило на сорте Золотой Дон 24,5-43,5%; на сорте Велика - 48,4-81,0%. В менее влагообеспеченном 2020 г. (ГТК = 0,6) это превышение было на уровне - 53,3-110,3% и 17,7-41,7% соответственно. Увеличение массы грозди у сортов винограда в вариантах с обработкой регуляторами роста растений наблюдается преимущественно вследствие повышения количества ягод. Выявлено, что двукратная обработка растений физиологически активными веществами приводит к значительному снижению ягодного показателя и росту показателя строения грозди винограда. Оптимальным вариантом двукратной обработки растений сортов столового направления использованиия являются: для сорта Золотой Дон - Циркон, 0,6 мл/л; для сорта Велика - Эпин-экстра, 3,2 мл/л, в более увлажненных условиях 2019 г., что позволило повысить урожайность кустов на 46,7 и 81,1% соответственно. В засушливых условиях 2020 г. обработка сорта Золотой Дон препаратом Эпин-экстра в концентрации 3,2 мл/л и сорта Велика Цирконом, 0,6 мл/л, была наиболее эффективной, увеличив урожайность в 1,5-2,0 раза по сравнению с контролем. The effect of plant growth regulators Gibberellin, Zircon and Epin-extra on mechanical composition of the bunch, cropping capacity and sugar content in the juice of berries of three table grape varieties in the conditions of Pridnestrovie was studied. The influence of physiologically active substances on changes in the bunch weight, number of berries per bunch and cropping capacity depending on the meteorological conditions of the year was determined. It was found that in the more humid conditions of 2019 (HTC of 1.0), the bunch weight increase in experimental variants in comparison with the control plants was from 24.5% to 43.5% in ‘Zolotoy Don’ grape variety, and from 48.4% to 81.0% in ‘Velika’ grape variety. In the less moisture-rich 2020 (HTC of 0.6) this exceeding was at the level of 53.3%-110.3% and 17.7%-41.7%, respectively. An increase in the bunch weight of grape varieties treated with plant growth regulators is mainly observed due to an increase in the number of berries. It was found that two-fold treatment of plants with physiologically active substances leads to a significant decrease in the berry index and an increase in the index of grape bunch structure. The best variant for two-fold treatment of plants is Zircon, 0.6 ml/l, - for ‘Zolotoy Don’ variety; Epin-extra, 3.2 ml/l, - for ‘Velika’ grape variety in more humid conditions of 2019, resulting in the increase in cropping capacity of bushes by 46,7% and 81.1%, respectively. In the arid conditions of 2020, the treatment of ‘ Zolotoy Don’ variety with Epin-extra at a concentration of 3.2 ml/l and ‘Velika’ variety with Zircon, 0.6 ml/l, was the most effective, increasing the yield by 1.5-2.0 times compared to the control.

The use of plant growth regulators is one effective solution to improve sugarcane yields and sugar content in several countries. In this study, we examined the role of gibberellin acid (GA3) and glyphosate (Gly) plant growth regulators to determine the appropriate concentration of GA3 and Gly to increase the yield of sugarcane and sugar accumulation, respectively. The statistical results showed that GA3 was sprayed at 150 ppm to increment the actual yield by 19.94%; sucrose accumulation increased by 2.21%. With Gly treatment, although the yield decreased by 3.17%, sucrose accumulation increased by 11.27% compared to control trials. In this study, the combined concentration of 150 ppm of both GA3 and Gly gave the best results, for which sucrose accumulation increased from 2.21% to 10.74% and from 19.94% to 20.97% for actual yield. The results led to increased net income compared to the control. To address concerns about residues of plant growth regulators, residues of GA3 and Gly were evaluated after the sugarcane harvest using the HPLC and UV-vis methods, respectively. The analyzed results showed that their residues were lower than what is permitted in several countries. This showed the applicability of the study, on a large scale, to increase sucrose accumulation, productivity of sugarcane, and profit for farmers.

Formulation of the problem. Among the main opportunities for improving seed production and the technology of growing sunflower in general is the use of plant growth regulators (further – PGRs). The main problem of PGRs is their strong dependence on weather conditions during the processing of plants. In addition, with the rapid increase in the number of PGRs in the State Register of Pesticides and Agrochemicals, their effect on various types of genotypes and their functionality under uncontrolled weather conditions remains poorly understood. Relevance of the topic. One of the most cost-effective and proven effective is the use of plant growth regulators. To date, a whole series of synthetic growth regulators, which in its composition has the active substances of humic origin, mineral compounds and extracts with different plants. But today the reaction of each genotype of sunflower separately from each other under the action of PGRs with different active substances remains little studied. Purpose. Study of the response of various genotypes of lines, hybrids and varieties of sunflower to the use of plant growth regulators. Material and methods. The studies were carried out in the period from 2018–2020., on the experimental field of the Department of Genetics, Breeding and Seed Production of KhNAU named after V.V. Dokuchaev. Lines, experimental hybrids and varieties of sunflower were used as the studied genotypes. Plant growth regulators Fulvital Plus, EcoStim, QuadroStim and applied by spraying during the growing season in the phase of 2–5 true leaves, and again in the phase of the sprocket. Conclusions. On average, over the years of research, the productivity of sterile lines increased from 0.7 to 38.1 %, depending on the PGRs and genotype. It is noted that lines SKh808A and SKh1002A have a greater potential to increase the structural indicators of the yield. One of the factors is their high adaptive capacity to the environment. The average rate of increase in line productivity according to PGRs from 5.1 g formed in the SKh1002A line and in SKh808A by 7.1 g. The weight of 1000 seeds increased from 0.3 to 24.7 % depending on PGRs, natural seeds and was within from -3.7 to 17.3 % depending on the drug and the line. The influence of PGRs on fertile lines of sunflower was weaker in comparison with sterile lines. By factor B, an increase in productivity was noted in the Kh785V line by 15.8 % and in the Kh1012B line by 27.7%, respectively. The main influence of PGRs in these lines under study was an increase in the mass of 1000 seeds. Thus, this indicator was 44.4 g for the Kh1012B line, which is 30.3 % more than the control and in the Kh06135V line – 53.1 g, an increase of 15.3 % to the control. The low performance of fertile lines compared to sterile lines is a consequence of the energy consumption of plants, since fertile lines produce pollen during the growing season, while fertile lines spend only energy on seed formation. The use of PGRs turned out to be quite effective in experimental hybrids. An increase in the genetic set occurs precisely during the creation of hybrids, the manifestation of heterosis increases the productive and adaptive capabilities of plants. The increase in the productivity of the hybrids was in the range of 0.3–19.6 %, the mass of 1000 seeds was in the range of 3.4–16.7 %. The productive characteristics of sunflower varieties had a low response to the use of PGRs Fulvital Plus, EcoStim and QuadroStim during the research period 2018–2020.

В статье представлены результаты изучения влияния регуляторов роста (гиббереллин в концентрации 100 мл/л и мицефит в трех концентрациях - 1, 10 и 100 мг/л) при обработке растений винограда сорта технического направления использования Солярис перед цветением и в период постоплодотворения, на формирование биологических показателей центральных почек зимующих глазков. Рассчитаны коэффициенты плодоношения (К), плодоносности (К), и продуктивности (К), и сделан анализ центральных почек зимующих глазков по длине однолетнего побега, имеющего наибольшее практическое значение (по 10 глазкам). Для установления потенциальной закладки эмбриональных соцветий в центральных почках зимующих глазков на растениях, обработанных гиббереллином и мицефитом, использован метод микроскопирования. Выявлено, что в вариантах обработки растений сорта Солярис регуляторами роста отмечена высокая закладка эмбриональных соцветий в центральных почках зимующих глазков по длине побега, т.е. под урожай будущего года. В целом по всей длине побега максимальные значения коэффициентов плодоношения, плодоносности и продуктивности зимующих глазков оказались в вариантах обработки гиббереллином перед цветением и мицефитом в концентрации 10 мг/л в период постоплодотворения. Этому способствовала наибольшая закладка плодоносных глазков с 2-3-мя соцветиями. Лучший вариант для снижения длины обрезки плодовой стрелки выявлен в варианте обработки мицефитом в концентрации 10 мг/л в период постоплодотворения, где коэффициент продуктивности составил 1,52 в зоне 4-го глазка. This article presents the study results of the influence of growth regulators (gibberellin in concentration of 100 mg/l and mycephitis in three concentrations - 1, 10 and 100 ml/l) when processing grape plants of the winemaking variety ‘Solaris’ before flowering and during post-fertilizing period on the formation of biological parameters of central buds of the wintering eyes. The coefficients of fruiting (К), potential fruiting capacity (К), and productivity (К) were calculated along with the analysis of the central buds of wintering eyes lengthwise the annual shoot of the most practical value (for 10 eyes). Method of microscopy was used to establish the potential laying of the embryonic inflorescences in the central buds of wintering eyes in plants processed with gibberellin and mycephitis . In the variants of processing plants of ‘Solaris’ variety with growth regulators, a high level of laying of the embryonic inflorescences in the central buds of wintering eyes lengthwise the shoot was observed, i.e. for the crops of next year. In general, maximum values of coefficients of the fruiting, potential fruiting capacity and productivity of wintering eyes lengthwise the shoots were identified in the variants of processing with gibberellin before flowering and mycephitis in concentration of 10 ml/l during the post-fertilizing period. It was promoted by the biggest laying of fruiting eyes with 2-3 inflorescences. The best option to reduce the length of fruit cane pruning was revealed in the variant of processing with mycephitis in concentration of 10 ml/l during the post-fertilizing period with the coefficient of productivity obtained - 1.52 in the level of the 4th eye.

Yield And Quality

Background: The South Gujarat hilly part is considered to be a non-traditional area of strawberry cultivation in India. The poor farmers of this region are cultivating strawberries under open field condition. Both, the yield and quality of strawberry fruits of this region are not up-to-the-mark as there in other parts of the country. Hence, a low-cost improved production technology is required to maximize yield as well as improve the quality of strawberry fruits. Method: Uniform runners of strawberry cv. Winter Dawn were grown in open field under paddy straw as bedding material. Foliar spraying of plant growth regulators viz. NAA (50, 75, 100 and 125 mg l-1) and GA3 (50, 75, 100 and 125 mg l-1) were done at 30 and 60 days after planting. The experiment was laid out in randomized block design with control plants receiving no spray treatments and replicated thrice. Result: The plant growth parameters like plant spread, number of leaves, number of crowns, leaf area, length of petiole, number of runners were recorded maximum with the application of 100 mg l-1 GA3. This treatment was also found to be the best in respect of number of flowers, number of fruits, fruit weight, marketable and total fruit yield of strawberry. Strawberry fruits with the highest total soluble solid, ascorbic acid, reducing sugar, non-reducing sugar and total sugar content were recorded in the plants which received 125 mg l-1 NAA. However, the plant growth regulator treatments failed to influence any significant effect on days taken to 50.0% flowering, fruit firmness and acidity content of strawberry fruits.
