Abstract. The purpose – to study under cultural conditions in the Bashkir Cis-Urals three samples of Allium nutans L.: Bashkir, Novosibirsk (broadleaf and narrow-leaved form). Studied: phenology, biomorphology, reproduction, agricultural technology and biochemical composition. Methods. The study was conducted in 2017–2020 at the collection site of onions in the South Ural Botanical Garden-Institute of the UFRC RAS. Analysis of the seasonal rhythm of growth and development, winter resistance, resistance to adverse weather conditions, pests and diseases, reproduction rate and seed productivity was carried out according to generally accepted recommendations. Results. Drooping onion is a long-lasting medium-late-flowering plant. Spring growth of A. nutans samples occurs in the 2nd–3rd decade of April, leaf growth in the spring is initially expressed in accelerating the growth processes of last year's etiolated leaves, and only then new young leaves come to the soil surface. The appearance of the flower arrow occurs in mid-June, the beginning of budding falls on the 2nd–3rd decades of June and lasts 30–35 days. Novosibirsk samples bloom in mid-July, the Bashkir sample – a week later. The flowering phase lasts an average of 35–41 days. Seeds ripen in August-September. In Novosibirsk samples, seeds mature in 16–19 days, in the Bashkir sample – in 25 days. The maximum number of seeds forms the Bashkir sample 647–1031 pcs. (average 835.0 ± 53.5). Scientific novelty. For the first time, the biochemical composition of samples of this onion was made and analyzed. According to the maximum accumulation of vitamin C and carotene, the Bashkir sample differs (104.92 mg% and 166.4 mg/kg, respectively). In the Novosibirsk sample (narrow-leaved form), the maximum amount of sugar and starch (8.8 and 6.12%, respectively) and the minimum amount of vitamin C (41.53 mg%) were found. The Novosibirsk sample (broadleaf form) contains more protein (17.06%) and a minimum amount of carotene (83.2 mg/kg). According to other indicators (solid, nitrogen, raw fat), the studied samples differ little from each other.

The sensitivity of the reproductive structures of Forsythiasuspensato the complex influence of undifferentiated environmental factors has been studied.The monitoring sites are located in 15 different park ecosystems in 6 administrative districts of Kyiv. Data from the Borys Sreznevsky Central Geophysical Observatory (air pollution index (API) and meteorological conditions for 2018-2020) were used to assess the conditions of the growthenvironment. The influence of a complex of ecologically important factors during the flowering offorsythia on the quality of the formedpollen is noted. Thus, growing plantsfor a long time in conditions with a low level of air pollution (APIup to 5.0) in abnormal weather conditions in 2020,40-50% less fertile grainswere formed. And forplants, which grow in areas with increasedlevel (API5.0-7.0) and high level (API7.0-14.0) of air pollution, the share of fertile grains in the pollen population decreased by 60-80%. In the closed bud,the pollen has higher resistance to a complex of exogenous growth factors. Forsythia plants, which are located in large parklands, lose less pollen quality in adverse weather conditions and affected byurbotechnogenic factors. F. suspensa is an acceptable indicator of the level of environmental pollution by the deviation of pollen fertility from the control value. In areas with high aerogenic load, for example, areas with large highways (Bus Station «Darnytsia»), as well as with a significant recreational load (HolosiivskyiPark, Recreation Park on the Olena Teliha Street) much smaller pollen is formed. Itis noted that the conditions of forsythia growth affect the quantitative indicators of the formed pollen not only in the flower but also in the closed bud, which confirms the chronic effect of the complex of ingredients of aerotechnogenic emissions on plants of this species. The coefficient of sterility of pollen (CS) was used to objectively compare the data of 2019 and 2020 on the condition of the generative organs of F. suspensa in the studied areas. The calculation of the CS confirmed that in the closedbud pollen has a higher resistance to exogenous factors. In areas with high and increased levels of air pollution,during budding and flowering of plants (March-May,) there is a much higher CS of pollen of F. suspensа. Significant parkland territoriesof the city (for example, HolosiivskyiPark, Botanical Garden named after O. V. Fomin) provide less stressful conditions for growth and development of plants, even with the "very high" level of air pollution (ISA above 14.0) observed in April 2020 on this territory.The study of the susceptibility of F. suspensаpollen to growing conditions will be continued, as the prospects of using this species for bioindication of ecological status and zoning of park ecosystems of Kyiv according to the gradient of anthropogenic impact have been revealed.Key words:forsythia, fertility, coefficient of sterility of pollen, bioindication. Проведене дослідження чутливості репродуктивних структур Forsythiasuspensaдо комплексного впливу недиференційованих факторів навколишнього середовища. Моніторингові ділянки розташовані в 15 різних паркових екосистемах 6 адміністративних районівКиєва. Для оцінки умов середовища вирощування рослин використані дані Центральної геофізичної обсерваторії імені Бориса Срезневського (індекс забруднення атмосферного повітря (ІЗА) та метеорологічні умови за 2018-2020 рр.). Відмічено вплив комплексу екологічно важливих факторів (за показниками відхилення від норми середньої місячної температури повітря та місячної кількості опадів у Києві) уперіод квітування форзиції на якість сформованого пилку. Так, за тривалої експозиції рослин в умовах з низьким рівнем забруднення повітря (ІЗА до 5,0) в аномальних погодних умовах 2020 р. сформувалось на 40-50% менше фертильних зерен. А у форзиції, яка росте на територіях з підвищеним (ІЗА 5,0-7,0) та високим (ІЗА 7,0-14,0) рівнями забруднення частка фертильних зерен в популяції пилку зменшилась на 60-80%. У закритому бутоні пилок має вищу стійкість до комплексу екзогенних факторів середовища зростання. Рослини форзиції, які розташовані у значних за площею паркових насадженнях, менше втрачають якість пилку за несприятливих погодних умов та дії урботехногенних чинників. За відхиленням показника фертильності пилку від контрольного значення F. suspensaє допустимим індикатором рівня забруднення середовища. На територіях з підвищеним аерогенним навантаженням, наприклад, ділянки з автотранспортними магістралями (Автостанція «Дарниця»), а також зі значним рекреаційним навантаженням (Голосіївський парк імені М. Рильського, Парк відпочинку по вул. Олени Теліги)формується значно дрібніший пилок. Відмічено, що умови росту позначаються на кількісних показниках сформованого пилку не лише в квітці, але й в закритому бутоні, що підтверджує хронічний вплив комплексу інгредієнтів аеротехногенних викидів нарослини цього виду. Для об’єктивного співставлення даних 2019 і 2020 рр. щодо стану генеративних органів F. suspensaна досліджених ділянках був використаний коефіцієнт стерильності (КС) пилку. Розрахунок КС підтвердив, що в закритому бутоні пилок має вищу стійкість до впливу екзогенних чинників. Вищий КС був у F. suspense, з ділянок, на яких в період бутонізації і квітування рослин (березень-травень) відмічений високий і підвищений рівень забруднення атмосфери. Значні за площею паркові насадження міста (наприклад, Голосіївський парк, Ботанічний сад ім.акад. О.В. Фоміна) забезпечують менш напружені умови росту і розвитку рослин навіть при відміченому в квітні 2020 р. «дуже високому» рівні забруднення повітря (ІЗА вище 14,0) на цих територіях. Дослідження чутливості пилку F. suspenseдо умов вирощування буде продовжене,оскільки виявлена перспективність використання цього виду для біоіндикації екологічного стану та зонування паркових екосистем Києва за градієнтом антропогенного впливу.Ключові слова: форзиція, фертильність, індекс стерильності, біоіндикація.

Abstract This article presents the results of research on the biochemical composition of green and yellowing leaves of 64-year-old bipedal ginkgo (Ginkgo biloba L.) seed and pollen trees growing in the Botanical Garden of the Academy of Sciences of Uzbekistan, introduced to Uzbekistan in the last century. Biochemical analyzes recorded the presence of 6 types of vitamins and 44 macro- and micronutrients in the leaves of the ginkgo tree. Vitamin C levels were found to be lower in the seed tree than in the pollen tree. The amount was 35.8 mg/% in the green leaves of the seed tree and 34.4 mg/% in the yellowed leaves. Ginkgo leaves contain important macro-and micronutrients such as Ca, Mg, K, Al, Fe, Cu, Mn, Zn, Mo, Co, I, Se, which are necessary for the vital activity of the human body and normal metabolism. The green leaves of the two-leafed ginkgo pollen tree contained 27577.288 mg/l of calcium, 11562.299 mg/l of potassium, the leaves of the seed tree 13912.903 mg/l of calcium and 7491.462 mg/l of potassium. At the same time, the green leaves of ginkgo contain 3073.807 mg/l – 7977.459 mg/l magnesium, 4353.72-5003.88 mg/l phosphorus, 501.073-515.343 mg/l sodium, 779.750 mg/l– the presence of silicon in the amount of 844.039 mg/l and iron in the amount of 373.023 mg/l – 655.148 mg/l was determined.

Pyrus zangezura Maleev (Rosaceae) is a rare species representing the native vegetation of Armenia (Southern Transcaucasus). It was first described in 1936. P. zangezura has been cultivated at the Peter the Great Botanical Garden of the Komarov Botanical Institute (St. Petersburg, Russia) since 1949, where it has reached the height of 8,0 m. For many years, it was in its vegetative state. The first flowering was observed in 2016 (the plant entered the reproductive state). The first progeny from seed was obtained in April 2019. Fruit size was assessed for P. zangezura plants in the dynamics of their development. The studied plants of P. zangezura in the environments of St. Petersburg have demonstrated a high fruiting potential – on average, 109 flowers per 1 m of a shoot. Observations have shown that not all ovules in the opened flowers of P. zangezura are fertilized and produce fruits and seeds. A significant part of the opened flowers, a few days after the onset of flowering, dry up and fall off. On average, 7 fruits are set on 1 m of the shoot in P. zangezura. The reasons for the low flower setting may be variable: impaired pollination processes and insufficient fertility of pollen, underdevelopment of the flower morphological structures, or lack of pollinating insects due to adverse weather conditions. An X-ray analysis of the seeds from the harvests of 2016, 2017 and 2018 showed that the number of plump and fully developed seeds (grades IV and V) in fruits has been growing year by year. As an ornamental plant, P. zangezura may adorn any botanical garden, but it is also promising for urban landscaping, for example, in St. Petersburg. Even in the vegetative state, its elongated lanceolate glossy leaves make it appreciably different from the common P. communis L., and it is especially ornamental during flowering and fruiting. It is as winter-hardy as the common pear-tree, demonstrates resistance to diseases and pests, and may be of importance for breeding programs aimed at the development of resistant cultivars for the Northwest of Russia.

Relevance. Introduction and variety study of flower and ornamental crops is one of the main tasks of botanical gardens, which aims to expand the promising assortment for domestic floriculture.Results. In the period from 2018 to 2020 varieties of hybrid iris (Iris x hybrida hort.) from the garden group “tall bearded” were studied in the Stavropol Botanical Garden. The presented 13 varieties belong to foreign selection. Basically, the varieties are characterized by medium or early flowering periods with an average duration of 11-15 days. In the course of the study, biometric characteristics, the economic and biological properties of the varieties were analyzed. The varieties with the longest duration and productivity of flowering were identified. The ability to bear fruit, which is important for further breeding work, was noted in three varieties: Autumn Circus, Pallida Variegata, Immortality. The main disease that harms the studied culture is heterosporiosis. The most resistant to diseases are the varieties Afternoon In Rio, Bye Bye Blues, Pallida Variegata (up to 10% damage). The detected pests (flea beetle, aphid, mole cricket, etc.) generally cause minor damage to the studied plants. In the assessment of decorativeness, 11 parameters were analyzed using a 100-point scale and taking into account the conversion factor. The color, size, shape of the flower, aroma, inflorescence, duration and abundance of flowering, resistance to adverse weather conditions, decorative vegetative part of plants, originality, condition of plants were taken into account. As a result of the variety study, 9 highly decorative varieties were identified: Bye Bye Blues, Stardock, Autumn Circus, Lotus Land, Power Point, Good Day Oregon, Lorilee, Conjuration, Afternoon In Rio.

Abstract. The purpose is to study the phenology, morphometry, reproductive biology, and propagation characteristics of the following species and samples of wild ramson onion: A. microdictyon Prokh. (Bashkir sample), A. victorialis L. (Moscow and Syktyvkar samples), A. ursinum L. (Moscow sample), A. ochotense Prokh. (Syktyvkar and Irkutsk samples). Methods. The study of wild ramson samples was carried out in 2016-2020 under the conditions of the culture in the South-Ural Botanical garden-institute of the UFRC RAS (Bashkir Cis-Urals, northern forest-steppe). The study of the seasonal rhythm of growth and development was carried out according to the method of phenological observations by I. N. Beideman and I. V. Borisova. Determination of winter hardiness and resistance to adverse weather conditions, pests and diseases, reproduction coefficient and seed productivity was carried out according to generally accepted recommendations. Results. According to the phenorhythmotype, the studied species are short-growing, spring-early-summer flowering. A. ursinum – ephemeroid, A. microdictyon, A. ochotense and A. victorialis – hemi-ephemeroid. The flowering phase occurs in late May-early June. The duration of flowering of wild ramson samples by year is 13-22 days. Seed maturation occurs in July. A. ursinum vegetation ends in July, the remaining samples-in August. The largest number of fruits and seeds are allocated samples of A. victorialis and A. microdictyon, the smallest – A. ursinum. Samples of A. microdictyon, A. ursinum and A. victorialis have a high percentage of fruit blooming. The weight of 1000 seeds of A. microdictyon is 3.6 g, A. ursinum – 5.9 g, A. victorialis – 6.3–6.7 g, A. ochotense – 7.9–8.5 g. Wild ramson seeds when sown in the open ground do not germinate in the same year: autumn sowing sprouts in 17–18 months, spring – in a year. To accelerate germination, it is recommended to stratify seeds for 2.5–3 months at a temperature of 0–3 °C. Scientific novelty. Research work on the study of wild ramson onions in the region of the Bashkir Cis-Urals has not yet been carried out. These species of onions have a wide resource value, which was caused by the high relevance of these studies.

Crop Conservation

Planting row crops into a stale seedbed has gained popularity in recent years. This concept uses tillage either after harvest in the fall or early in the spring to smooth the seedbed and eliminate ruts and excess residue on the soil surface. Tillage is not used immediately before planting, thus conserving moisture, eliminating costly and time-consuming tillage trips at planting, and allowing more timely planting. While stale seedbed planting minimizes tillage to establish the crop, conservation is not the primary objective of this concept; rather, timely stand establishment following adverse weather conditions has been the driving force behind the popularity of stale seedbed programs. The stale seedbed approach has been used with success on a variety of soils in the southern U.S., but is best suited on the poorly-drained clay soils in the Mississippi River Delta. The system has been adapted for use in soybean, cotton, corn, and rice. A key component of a well-prepared stale seedbed is the absence of weeds at planting. Producers must keep in mind that weeds present and not controlled at planting have the potential to significantly impair stand establishment and crop yields. Although these weeds are often beginning to senesce by the time soybean planting occurs, they are still using soil moisture and shading newly emerging crop plants early in the season.

The level of biochemical composition of sweet cherry fruits of different ripening periods was investigated. It has been established that the content of chemical elements in sweet cherry fruits depends on a number of factors. Fruits ripening period is listed frstaming the features of the pomological variety. Weather conditions during the formation and ripening of sweet cherry fruits have a signifcant effect on the content of chemicals. The variety Melitopolskaya krapchastaya was revealed to have a high content of dry soluble substances among all the studied varieties. In the group of late-ripening varieties, the smallest difference in the amount of acidifed acids in fruits between varieties is observed. The high content of organic acids was recorded for the Donetsk Ember variety, and the lowest one for the Turquoise variety. On average, for the varieties of different ripening periods, the highest content of organic acids was noted for early ripening varieties, and the lowest one for late ripening varieties. Having considered all the studied varieties as a whole, it can be asserted that the content of titratable acids was the highest in the fruits of the mid-ripening variety Alenushka, in relation to all other varieties; the lowest amount of organic acids was recorded for the late-ripening varieties Amazonka. The sugar content in the fruits of late-ripening sweet cherry varieties exceeded the average values of the groups of early-ripening and mid-ripening varieties. The mid-ripening variety Mirage was characterized by a high content of vitamin C, and the lowest value of this component of the chemical composition was obtained for the early-ripening variety Mlievskaya yellow. Taste qualities and biochemical composition of fruit and berry crops largely depend on the characteristics of the variety and climatic conditions of cultivation.The early ripening varieties Dar Mliyeva and Zoryana received the maximum tasting assessment. In the group of mid-ripening varieties, the Melitopolskaya krapchastaya variety was highly appreciated, and among the late-ripening varieties, the Turyuza variety. Key words: cherry varieties, dry soluble substances, sugars, organic acids, vitamin C, sugar-acid coefcient.

Abstract. Potato is one of the most important human foods. It possesses high taste and nutritional properties. The optimal ratio in potato tubers of organic and mineral substances necessary for a person determines its value as a food product. The tubers contain on average 76–78 % of water and 13 to 36 % of dry matter, of which 12–15 % are starch, 1–3 % protein and about 1 % – mineral compounds. Potato proteins have a very high biological value, since they contain a complex of essential amino acids that are not synthesized in the human body and must be obtained from food. Potatoes are an essential source of vitamin C. The studies were carried out on the experimental field of the educational and experimental farm “Uralets” of the Ural State Agrarian University (USAU), the village of “Studencheskiy”, for three years (2016–2018) in the climatic zone of the Middle Urals. Purpose of research. The objective of this study was to study the influence of the feeding area of “Gala” potato, the use of fungicides on the yield and quality of tubers in the conditions of the Middle Urals. Results. The results analysis on the mineral and biochemical composition of tubers showed that the total nitrogen content changed from 0.25 to 0.37 % and did not depend on the feeding area. The phosphorus content varied from 0.034 to 0.063 % and depended on the feeding area, i. e. the less often the plantings were, the more phosphorus was contained. Potassium content fluctuated over the years. The starch content was stable and did not depend on weather conditions and feeding area and ranged from 11.3 to 15.4 %. The tasting result showed that the studied potato variety Gala has high taste. According to the taste assessment, the Gala variety was rated 5 points in the control variant. The variant with the use of the fungicide shirlan yielded to it by 0.5 points. Scientific novelty. The scientific novelty lies in the fact that for the first time in the conditions of the Middle Urals, the influence of the feeding area on the mineral and biochemical composition of potato tubers (nitrogen, phosphorus, potassium, dry substances, vitamin C and others).

Introduction Experiment

Species and cultivars of the genus Allium L., family Alliaceae occupy a significant place is in the collection of floral and ornamental herbaceous perennials of the Stavropol Botanical Garden. The first supplies of plants to the exhibition areas of the garden took place in 1962. Nowadays, 34 taxa grow in the collection of herbaceous perennials. Research work on the study of local species and introduced species has been carried out since 2010. In 2020, the results of an introduction experiment to study the seasonal rhythms of plant growth and development, their ecological growth conditions, biomorphological indicators, decorative qualities, and economically valuable features, resistance to adverse weather conditions, pests, and diseases were summed up. Analyzing the data obtained, the author identifies the most promising species and cultivars for the introduction on the territory of the Stavropol upland in the conditions of a sharply continental climate and the zone of unstable moisture. As a result of the final assessment of the adaptive features of bows and their decorative qualities, the following groups were identified: very promising – 21, promising – 7, and unpromising – 6. The research team suggests using highly decorative and decorative species, resistant to cultivation in Stavropol and other localities in the region, in practical floriculture. Low-promising and low-decorative ones are valuable species and cultivars used in medicine or consumed as food and rare and endangered species of the Russian Federation 28 and neighboring countries. Plants of the genus Allium in the collection of the Stavropol Botanical Garden are a scientific base for holding regional environmental seminars for schoolchildren and students of higher educational institutions. Acquaintance with this group of plants is of great interest for landscape design specialists and amateur flower growers.
