Effect of Presowing Magnetic Field Stimulation on the Seed Germination and Growth of Phaseolus vulgaris L. Plants

Background: The problem of the influence of magnetic fields (FMs) on the growth and development of common bean plants is still far from being fully explained due to its complicated physical nature and the geometry of the seeds. FMs can practically penetrate through living organisms. Aim: The present work aimed to determine the effect of the presowing FM stimulation of common bean seeds on plant growth and development elements. Material and Methods: The present study was based on a field experiment carried out between the years 2015 and 2017 in Żyznów (N 49°81′, E 21°84′, 239 m above sea level). The experiment was carried out using three repetitions of the randomized block method. The experimental factor was the amount of exposure to FM seed stimulation: (I) 15 s, (II) 30 seconds, and (III) the control object without seed stimulation. The plant material of the study was a common bean: cv. Gold Saxa. Results: The biostimulation of the sources with an FM improved the germination energy, strength, and capacity of the seeds. The presowing FM stimulation of the common bean seeds favourably affected the fresh weight of the first and fifth leaves but did not affect their dry weight. The leaves’ collection dates measured the new first and fifth plates and their dry weight content. The collection dates of the leaves determined the level of the fresh weight of the first and fifth leaves and the content of their dry weight. Conclusions: The biostimulation of the seeds with the FM contributed to a higher germination capacity, energy, and strength of the common bean seeds. The highest level of the leaves’ fresh weight was achieved during full flowering, and the highest dry matter content of the leaves was found in the phase of pod setting.

Response of stressed seeds of grain crops to changing conditions and duration of their storage

The article investigates the dynamics of the formation of an adaptive response in stressed seeds of spring wheat and barley, depending on the duration and storage conditions.

EFFECT OF γ-IRADIATION ON SEED GERMINATION AND GROWTH OF GYPSOPHILA THYRAICA KRASNOVA (CARYOPHYLLACEAE) SEEDLINGS

Analysis of laboratory germination and germination energy of Gypsophila thyraica Krasnova s. str. - a rare, relict, Podil endemic species. The seeds were irradiated with small doses (5, 15, 30 Gy) of gamma radiation (60Co) and germinated in laboratory conditions for 14 days in two repetitions. It was established that the seeds of G. thyraica irradiated with γ-rays prevailed in terms of the rate of germination and further growth and the number of seedlings. A stimulatory effect on germination, seed germination energy and seedling development was established with γ-irradiation at doses of 15 and 30 Gy. The energy of germination in all irradiated samples is low, in the control non-irradiated version it was not determined due to the absence of germinated seeds. The analysis of morphometric indicators also showed positive dynamics: in irradiated samples, the total size of seedlings increased (by 5-6 times compared to the control sample), depressed individuals were practically absent, while in control samples growth slowed down, seeds often did not develop, even after the start of germination. In general, the results of samples 1 and 2 are similar and confirm the conclusion about the stimulating effect of low doses of γ-irradiation on seeds.

Практика повышения посевных качеств семян сосны обыкновенной (Pinus sylvestris L.) и ели европейской (Picea abies L.)

The article notes that the efficiency of reforestation in the Russian Federation is insufficient, the main problems are shortage and high cost of planting material. Techniques for presowing treatment of seeds in order to increase germination energy and germination of seeds are analyzed. A review of literature sources has been conducted to assess the application effectiveness of plant growth regulators in soaking seeds in order to increase their progenity and increase the resistance of seedlings to adverse factors. Soaking seeds does not require much effort and is the easiest way to treat seeds. A review of preparations (plant growth regulators) for seed processing from the «State Catalog of Pesticides and Agrochemicals» showed that mainly preparations are designed to stimulate the germination of seeds of agricultural plants, fruit and berry crops. Research is actively conducted to find effective preparations and their optimal concentrations for the treatment of coniferous seeds. Based on the review of research, a list of effective preparations for the treatment of Scots pine seeds has been established. Along with ready-made preparations of active substances, a promising way to influence the germination of seeds and increase the resistance of emerging plants to adverse factors may be plant raw materials in the form of wood wastes, parts of shrubs and trees, fall, herbaceous vegetation, including weeds, etc. A review of chemical, biological, physiological methods for improving seed quality showed that they can all be effective. The main principle of choosing the method of treating seeds should be the availability, economic feasibility and high efficiency of the preparation and devices.

The Coal Humic Product EldORost Shows Fertilizing and Growth Stimulating Properties on Diverse Agricultural Crops

The use of environmentally safe products of natural origin is a global trend today. A particular point of interest is the use of humic fertilizers. This is due to the growing awareness of the positive impact of humic substances on plant growth and development as well as on the quality of agricultural products and soil fertility. Humates are physiologically active substances. As a result, they regulate and intensify metabolic processes in plants and soil, and contribute to the bioavailability of nutrients to plants. EldORost is a new-generation humic product that contains humic substances with a high humification degree. In addition to humates, this product contains a complex of amino acids, macro-, and microelements in a bioavailable form for plants. The product is eco-friendly and completely soluble in water, which is a substantial advantage for drip irrigation systems. It can be used for all types of agricultural crops on a wide diversity of soils and climatic zones. It displays the properties of plant hormones while its optimum concentration is as low as 0.0001% (wt). The efficiency of this novel humic product was tested in laboratory and field tests conducted on potatoes and vegetable crops (tomatoes, cucumbers, cabbage, carrots, onions, beets). The obtained results showed high efficiency displayed in the significantly improved sowing quality of vegetable seeds, nominally increased the germination degree and seed germination energy, intensively stimulated the side root development in plants, accelerated the growth of biomass, increased the fruiting period, and reduced maturation on the yield of potatoes and vegetable crops. The obtained data allowed us to characterize this novel humic product from the perspective of an eco-friendly fertilizer and growth promoter.

UWAVE-2000 as an effective equipment for the microwave аssistant synthesis of N, N-diethyl-2-(mesitylamino)-N-benzyl-oxoethanamonium chloride – a compound with plant growth regulating activity

The synthesis of N,N-Diethyl-2-(mesitiylamino)-N-benzyl-oxoethanamonium chloride was carried out by N-alkylation with traditional method and using microwave and ultrasonic activation. The synthesized ionіс compound is characterized by IR, NMR 1H and 13C methods, and its growth-stimulating activity has been tested on Zea Mays L. maize seeds. The synthesis of N,N-Diethyl-2-(mesitilamino)-N-benzyl-oxoethanamonium chloride using unconventional methods such as microwave and ultrasonic activation resulted in higher yields in a shorter period of time than traditional method. The highest yield (98%) was achieved by microwave activation of UWAVE-2000 in a very short time, while in the classical caseit was lower and the reaction time was twenty-four times longer. The synthesized ionic compound positively influenced the germination and growth energy of maize seeds. In samples treated with solution N,N-Diethyl-2-(mesitylamino)-N-benzyl-oxoethanaminium chloride of mould lesions was not so many, so, the treatment of maize seeds with trimecaine benzyl chloride not only stimulates the plant growth, but also prevent fungi mould formation.

Изучение влияния способа внесения криопротекторов на сохранение семенного материала мяты длиннолистной при криоконсервации

Представленная статья посвящена оптимизации условий криохранения семенного материала мяты длиннолистной. Мята длиннолистная — эфиромасличное растение, активно применяемое в парфюмерной, фармацевтической и пищевой промышленности. В экспериментах по криохранению использованы следующие эндоцеллюлярные и экзоцеллюлярные криопротекторы: поливинилпирролидон (ПВП), глицерин и диметисульфоксид (ДМСО). Кроме того, исследовано влияние на сохранение ростовых характеристик семян при криоконсервации способа внесения криопротектора: при комнатной температуре и на ледяной бане. Исходная всхожесть семян мяты длиннолистной составила 76,3±2 %, а энергия прорастания — 70,3±1,8 %. При замораживании в жидком азоте без применения криопротекторов всхожесть составила 64,9±0,8 %, а энергия прорастания — 18,95±0,2 %. Следует отметить, что именно показатель энергии прорастания оказался чувствительным к депонированию семенного материала при экстремально низких температурах. Анализ результатов сохранения жизнеспособности семян мяты длиннолистной при замораживании их в криопротекторах различного состава в случае внесения их при комнатной температуре показал, что тенденция резкого снижения энергии прорастания наблюдается во всех вариантах эксперимента. Наилучшими вариантами криопротекторов для со-хранения ростовых характеристик семенного материала оказались ДМСО 2,5 % и ПВП 3 %, вносимые на ледяной бане. Всхожесть семян, сохраняемых в этих криопротекторах, составила 85,8±3,1 % и 87,6±2,3 % соответственно. Таким образом, выявлено, что оптимальным способом внесения криопротекторов при криоконсервации семян мяты длиннолистной является температура, близкая к 0 оС, в этом случае серьезно повышается как всхожесть, так и энергия прорастания семян.

Acylation of synthesized dithiocarbamates with acid chlorides was carried out and the corresponding derivatives of dithiocarbamic aromatic and heterocyclic thioanhydrides were obtained in the yields 58-85%. The structure of the synthesized compounds was identified by using elemental analysis, IR spectra, 1Н and 13С NMR spectroscopy. Laboratory study of growth-stimulating activity of new biologically active compounds onlaboratory germination and germination energy of wheat and soybean seeds was carried out.Conclusion.The best results were achieved when wheat seeds were treated with sodium indoline-1-carbodithioate and benzyl(methyl)carbamothio-4-fluorobenzoic thioanhydride at 0.001% concentration.Germination energy and laboratory seed germination were 100% and 100%, and for the standard -80% and 90%, respectively. It was found that seed treatment with new synthesized preparations intensively stimulates the growing and germination of wheat shoots in comparison with the control and the standard.

Development of an electrical ozonator for the treatment of agricultural products

This article presents an installation for producing ozone. Ozonators have found widespread use in agricultural production. The most efficient means of ozone production today are ozonators using electric discharge. They are simple in design and have high ozone yield in comparison with other methods. The ozonator is designed with the use of discrete elements, CMOS logic elements of medium integration, and operational amplifiers of medium accuracy. The design elements have galvanic connection to the 220/380 V network. The device consists of the following main functional elements: a master oscillator, a signal conditioning device, a display device, an amplifier, a high-voltage output stage and power supplies. This ozonator is intended for use in agricultural production, in particular for the treatment of crops. Experimental trials of the laboratory ozonator were carried out concerning treatment of winter wheat seeds with ozone to improve their sowing qualities. Particularly, winter wheat seeds were subjected to ozone treatment with ozone concentrations of 2.5, 35.0 and 55.0 mg/m3. At these concentrations, the dependence of germination energy of winter wheat seeds on the exposure and settling time from the moment of treatment to seed germination was determined. As a result of research, energy of germination increased by 17.0 % in comparison with the control, germinating capacity in the best variant changed from 77.0 % to 95.0 %.

BIOLOGICAL PRODUCTS AS A MEANS OF RESTORATION OF BLACK SOIL HEALTH

Usage of crop residues as fertilizer leads to soil intoxication and, consequently, to soil health deterioration. Usage of beneficial microorganisms solves this problem. The studies were carried out in 2018-2021 in order to study the effect of Gribofit and Imunazot microbiological products, nitrogen fertilizers, individually and in combination, on phytotoxic effect removal of the soil when plant residues are applied for fertilization in grain crop rotation on typical slightly eroded heavy loamy black soil. The experimental field is located in Kursk region, Medvenskiy district of Panino village. All residues were used for fertilization in all variants of the experiment; nitrogen fertilizers were additionally applied at a dose of 10 kg of a.r. N per 1 ton of straw in the second variant; in the third variant, seeds, soil, crops and straw residues were inoculated with biological products Gribofit and Imunazot; in the fourth variant, combined application of nitrogen fertilizers and biological products as studied. Specification of soil phytotoxicity was carried out according to international standard ISO 11269-2:2012, as a test culture, seeds of radish (Raphanus sativus L.) were used. Application of plant residues for fertilization for four years led to sustainable phytotoxic effect of the soil, reducing seed germination energy of the test crop from 88% to 57%. Usage of Gribofit and Imunazot separately and in combination with nitrogen fertilizers contributes not only to improvement of soil ecological state, but also to its health. Biological products increase seed germination energy of the test culture from 11% to 28% compared to absolute control, depending on the type of plant residues, and index of the assessed factor increases to 1.27. Application of nitrogen fertilizers with cereal straw contributed to low toxicity of class 4. Broad beans have the ability to reduce soil toxicity, but their effect lasts only during the period of crop cultivation.

Bioecofunge-C preparation impact on growth and development of pine planting material (Pinus sylvestris L.)

Pine plantations drying has been observed during the last decade. Mass drying occurs in the temperate climate zone forests. Scots pine has been signifcantly weakened in recent years, which may further result in a change in the type of forests in Zhytomyr Polissia. This article covers the issue of growing Scots pine seedlings treated with Bioecofunge-C. A study of the biological preparation effect on the germination and growth of Scots pine seedlings in the conditions of Zhytomyr Polissia was conducted. It was proved that the germination energy of Scots pine seeds was signifcantly higher in the areas where Bioecofunge-C was applied compared to the control and amounted to 95 %. An average increase in the height of the seedlings by 34.2 % and root length by 34.9 % was noted during the cultivation of one-year-old Scots pine seedlings in the forest nursery of the Korbutiv Forestry, where the seeds were treated with the preparate. Scots pine seedlings were treated (root dosing) during the growth and development of Scots pine seedlings. The obtained results showed positive dynamics in terms of height in comparison with the control treated with water. The preparate use is promising for obtaining high-quality planting material since the treatment with Bioecofunge-C ensure the preservation, obtaining high-quality planting material and the yield of seedlings. It has been established that obtaining high-quality planting material is one of the most important components of the technologies for growing tree and shrub plants at forestry enterprises of Ukraine. However, obtaining and high-quality planting material resistant to adverse factors requires improvement of existing or development of new measures and methods. It has been proven that the artifcial restoration of the Zhytomyr Polissia forests depends on the cultivation of high-quality planting material. Key words: forest plantations, height, growth technology, planting material, seeds, growth, Zhytomyr Polissia.
