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.

Background: The hormonal up-regulation and down-regulation in recalcitrant seeds, on the other hand, has received little research. We tested fou plant growth regulators from distinct families of phytohormones at the same time to better understand their differential input from maternal tissues to growing Syzygium cumini seeds. Methods: During April-June 2020, seeds were collected in their native habitats in the Western Ghats. Seeds were chosen at random from each treatment. The embryonic tissues of seeds were chopped up and frozen for LC-MS/MS hormonal profiling. Result: Except for ABA, the dynamics of key plant hormones in this recalcitrant seed were identical to that of desiccation-tolerant orthodox seeds. When compared to other conventional seeds, SA was shown to accumulate at an unusually high level in mature embryonic tissues, demonstrating the highly hydrated seed’s defense mechanism against fungal attack following seed shedding.

The Impact

The impact of the plant growth regulators (PGRs) Stimpo, Regoplant, and Charkor on the production of the second-generation energy crop Miscanthus × giganteus on marginal post-military soil was investigated during two vegetation seasons. The land, previously a tank training polygon, has not been in use since 1990 and has become marginal. Biological parameters (stem, shoot, and root lengths) and dry biomass values were evaluated in relation to the applied treatments. The multivariate general linear model (M-GLM) results showed a positive influence of Charkor on M. × giganteus development; the effect was markedly higher in the second year of vegetation. The impact of Stimpo and Regoplant was less noticeable; nevertheless, certain combinations of treatments showed satisfactory results. The M-GLM approach detected the inter-influence of the main factors of the production process, i.e., PGRs, soil, and year of growing. The results showed the predominant influence of year, PGRs and combined factor PGRs × year on the biological parameters; the other studied factors and their combinations were not as effective. Further research should focus on verifying the field-scale results for the M. × giganteus plantation established in a post-military area and compare the lab and field studies.

ABSTRACTAny improvement in agricultural systems that results higher production aimed to reduce negative environmental impacts and enhance sustainability plant growth regulators (PGRs) such as gibberellin have similar physiological and biological effects to those of plant hormones, and therefore used widely in agriculture to minimize unwanted shoot growth without lowering plant productivity.An experimental field was conducted at Giza Experimental Station Egypt, on sugar beet plants (Beta vulgaris L. var. Sara poly) with some plant growth regulators (gibberellin and proline) foliar application at three rates of zero (control), 100 and 200 mg l−1 and boron sources (Boric acid and B-NPs) with 75% of macro-nutrients from full dose.The main target of this study to evaluate another plant growth regulator source like proline which is safer than gibberellin for maximizing sugar beet biological parameters to reduce the gap between sugar consumption and production in presence of boron sources.Data showed that the foliar applications of gibberellin (GA3) at rate 100 mg l−1 and proline at 200 mg l−1 were found to be the more effective without significant differences for plant growth, productivity and quality may be due to increased N use efficiency, especially at sub-optimal macro nutrient fertilizers. Regard to boron sources, B-NPs had positive effect on all biological parameters under study due to sugar transport, cell membrane synthesis, nitrogen fixation, respiration, carbohydrate metabolisms, root growth, functional characteristics and development.

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.
