In the M.M. Gryshko National Botanical Garden National Academy of Sciences of Ukraine (Department of Cultural Flora), which is located in the north of the right bank of the forest-steppe zone, is being conducted for the introduction tests of plants of the species of the genus Isodon (Schrad. Ex Benth.) Spach. Representatives of this genus by number of species are most concentrated in East Asia – China, Korea and Japan, where they have long been known as medicinal plants and are used in traditional medicine, in particular, for the treatment of oncological diseases.In Ukraine, the Isodon genus is little known. During 2012–2018, the object of complex research was Isodon japonicus (N. Z. Burm) Hara var. glaucocalyx (Maxim.) H.W. Li. The article presents the results of studying the large life cycle of this plant species during the introduction. To establish age periods and plant conditions, classical methodical approaches are applied.The descriptive part of the work presents key morphological features that reflect changes in the shoot and root systems that a plant experiences during life. According to the duration of the study period, it was found that individuals of I. japonicus var. glaucocalyx undergo pregenerative and generative periods of development and all age states corresponding to them. It has been established that seedlings are characterized by the presence of two cotyledon leaves of a renal form, having a notch at the apex, and fragmentary lignification of root sections, which is a rather rare phenomenon. Juvenile plants lose cotyledon leaves, the shoot from the round becomes four-sided, the main root thickens. In immature plants, the shoot is stretched by lengthening the internodes, the leaves acquire the signs and dimensions of the present. In the virginal state, second-order shoots develop in plants, rhizome begins to form. For young generative individuals, there are 2–3 shoots, the development of a pair of skeletal roots, the beginning of the formation of caudex. This age condition begins for the vast majority of individuals in the first year of life. Adult generative plants reach a maximum in the development of the shoot and root systems: they have 3–5 vegetative-generative shoots, many-headed dense caudex. Spring renewal takes place: from the renewal buds – vegetative-generative shoots, dormant buds – vegetative shoots and from the buds of the plagiotropic rhizomes – partial single-shoot plants. This age condition lasts for three years. The age state of old generative individuals begins from the sixth year of plant life and is characterized by attenuation of organ-forming processes. This leads to a weakening of the escapes and root system and to the disruptive irreversible changes of the latter

The forest site capacity using was quantitatively assessed for the stands of the main forest-forming species of Ukraine, Scots pine and common oak, taking into account natural zones and forest types. The tables of productivity of modal and highly productive pine and oak stands have been developed. It has been found that the stands use an average of 50–75 % of the forest site capacity of lands. The average weighted value of the capacity used by pine forests was 68–76 % in the Polissya zone, 70–78 % and 68–73 % in the Right-bank and Left-bank Forest-Steppe zones respectively, and 54–78 % in the Steppe zone. For oak stands, the value was 71–75 % and 63–71 % for the Right-bank and Left-bank Forest-Steppe zones respectively and 65–75 % for the Steppe zone. The basis for increasing the productivity of forests was confirmed to be the differentiation of forest management systems and individual forestry activities on a zonal and typological basis.

Specific approaches, principles and methods of cognition of modern silvicultural landscapes are considered; it is stated that due to the fact that the difference between natural and anthropogenic silvicultural landscapes is only in their genesis, in the process of studying silvicultural landscapes, both classical and specific approaches, principles and methods can be used. Among the specific approaches, the historical-cartographic one with the inherent principles of historicism and methods of historical-genetic series of maps, historical-archaeological method is considered in more detail; system-adaptive with the principle of combination and methods of comparison of natural analogues and analysis of final results; landscape-biocoenotic and landscape-ecological with the methods of the leading factor, comparison of disturbed and control biogeocenoses and arealographic, as well as geoinformation approach in the knowledge of silvicultural landscapes. It is shown that all approaches, principles and methods of knowledge of forest anthropogenic landscapes should be applied depending on the available conditions and needs of practice. However, in the process of field research, landscape-biocoenotic and landscape-ecological approaches with their own principles and methods of cognition of forest anthropogenic landscapes were more often used. It is shown that in its implementation landscape scientists not only have the right, but also the obligation to use the rich experience of foresters. It is advisable to characterize the stand in the following order: dominant species by tiers (in tree, shrub and grass), quality, age, height of trees – in meters, trunk diameter – in cm, planting density. In abbreviated form, information about the forest tract is presented in the form of a kind of formula. These approaches, principles and methods were applied in the process of studying the forest anthropogenic landscapes of two regions of Ukraine – Podillia (Forest-Steppe Zone) and North-Western Pryazovia (Steppe Zone). The expediency and necessity of their application are substantiated in the process of dissertation research and confirmed by practice.Key words: Podillia, North-Western Pryazovia, research, silvicultural landscapes, approaches, principles, methods, significance, use. Розглянуто специфічні підходи, принципи і методи пізнання сучасних лісокультурних ланд-шафтів. Зазначено, що у зв’язку з тим, що між натуральними й антропогенними лісовими ландшафтами різниця лише у їх ґенезі, отже, у процесі дослідження лісокультурних ландшафтів можна застосовувати як класичні, так і специфічні підходи, принципи та методи. Серед специфічних під-ходів детальніше розглянуто історико-картографічний з притаманними йому принципами істо-ризму та методами історико-генетичних рядів карт, історико-археологічним методом; системно-адаптивний з принципом сумісництва та методами порівняння натуральних аналогів і аналізу кінцевих результатів; ландшафтно-біоценотичний та ландшафтно-екологічний з методами провідного чинника, порівняння порушених і контрольних біогеоценозів та ареалографічного, а також геоінформаційний підхід у пізнанні лісокультурних ландшафтів. Показано, що всі підходи, принципи і методи пізнання лісових антропогенних ландшафтів необхідно застосовувати залежно від наявних умов та потреб практики. Однак у процесі польових досліджень частіше використовували ландшафтно-біоценотичний і ландшафтно-екологічний підходи з належними їм принципами і методами пізнання лісових антропогенних ландшафтів. У цих підходах у разі картографування лісокультурних урочищ, крім характеристики рельєфу й властивостей ґрунтів, вагоме значення має аналіз деревостану. Показано, шо у його здійсненні ландшафтознавці не лише мають право, але й зобов’язані використовувати багатий досвід лісознавців. Характеристику деревостану доцільно проводити у такому порядку: домінуючі види за ярусами (в деревному, кущовому та трав’яному), бонітет, вік, висота дерев – у метрах, діаметр стовбура – у см, щільність насадження. У скороченому вигляді інформація про лісокультурне урочище представлена у вигляді своєрідної формули. Ці підходи, принципи і методи застосовано у процесі дослідження лісових антропогенних ландшафтів двох регіонів України – Поділля (Лісостепова зона) і Північно- Західного Приазов’я (Степова зона). Доцільність та необхідність їх застосування обґрунтовано у процесі дисертаційних досліджень та підтверджено практикою.Ключові слова: Поділля, Північно-Західне Приазов’я, дослідження, лісокультурні ландшафти, підходи, принципи, методи, значимість, використання.

As a result of expeditionary-route studies, the impoverishment of the composition of the segetal flora in maize crops was established when moving from the North-West to the South-East of the Ural region: from 37 species in the forest-meadow and mountain-forest zones to 10 in the steppe zone. Zonal features of the composition of weed communities associated with the hydrothermal gradient consist in the mutual substitution of annual monocotyledonous and dicotyledonous species with a stable contribution of perennial dicotyledons, as well as the replacement of mesophytic weeds with xerophytic species of the same families. A comparison of cross-spectrum herbicides effectiveness in the forest-steppe and forest-meadow zones showed the advantages of a post-emergent preparation with soil effect of Meister Power. In temperate soil fertility in the Southern area of the region, it is economically feasible to use post-emergent herbicides without soil effect, in Northern areas with stable moisture – soil ones.

The paper discusses the details of the application of geophysical research methods in the study of the landslide areas of the right bank of the Dnieper River within the forest-steppe zone of Ukraine. Geological and geophysical models of landslides are given. The specific tasks that are posed in studies of landslides were highlighted. There are three stages in studies of landslides which were defined: reconnaissance-methodological, detailed and monitoring. Also, sets of geophysical methods for these stages were designated. It is emphasized that the rational set of geophysical methods in the study of landslide processes is determined for each individual natural environment, taking into account: the possibility of performing field studies by a specific geophysical method on the area; the presence of differentiation of rocks by physical properties, that are used by the specific geophysical method; economic efficiency of application of the geophysical method. As an example, we described some of the results of geophysical studies, which were carried outon exemplary landslidesites onthe right bank of the Dnieper River within the forest-steppe zone of Ukraine near the Trypillia thermal power plant.

This article provides characteristic of the chemical composition of atmospheric precipitation on the territory of Ukraine and its potential impact on the environment and water bodies. In Ukraine, the rainfall is 650 mm/year in the northwest of the country (mixed forests), up to 300 mm/year in the south (steppe zone), in the Ukrainian Carpathians - up to 1,600 mm/year. Acidity of atmospheric precipitation (pH) on the territory of Ukraine according to monitoring meteorological stations is 5.9-6.3. Minimum values of mineralization of atmospheric precipitation are observed in a zone of mixed forests in the north of the country. In particular, according to the weather station of Teteriv, the mineralization of atmospheric precipitation is 27.0 mg/l. In forest-steppe and steppe zones, this rate gradually increases to 35-45 mg/l, reaching a maximum in the steppe zone at the Askania-Nova meteorological station (82.4 mg/l). In the chemical composition of atmospheric precipitation, anion predominates sulfates, and among cations - magnesium. Anthropogenic component of the total mineralization of atmospheric precipitation, calculated for the first time on the territory of Ukraine (meteorological station Kobelyaki) by comparison with the regional natural background, is 69%. Concentration of sulfate ions (8-24 mg/l) in atmospheric precipitation on the territory of Ukraine shows a high level of pollution with sulfur, which corresponds to IV-V levels o environmental pollution. It is noted that with increasing concentrations of sulfates in atmospheric precipitation a tendency towards a decrease in the pH in the water of Svityaz Lake is projected. Current research shows that at high concentrations of sulfates in atmospheric precipitation, the risk of falling individual rains with low pH (so-called acid rains) increases. Waters of high concentration of organic matter and low mineralization of water are widely distributed on the territory of Ukraine (catchments of Polissya and the Carpathian region): up to 100 mg/l in the meadows and up to 30 mg/l in the flood period. Often, the pH of water in them is 6-6.5 and precipitation of acidic precipitation can significantly affect their hydroecological state. The obtained results on the influence of chemical composition of atmospheric precipitation on water objects have a diagnostic character. For more specific results, special synchronized studies of the chemical composition of the water of experimental water reservoirs with sampling ofatmospheric precipitation are required.

Наведено результати досліджень з уточнення біо-логічних особливостей оленки волохатої (Epicometishirta Poda.) в промислових насадженнях суниці в зонілісостепу України. Встановлено, що жуки літаютьу теплі сонячні дні, найбільш інтенсивно з 10 годиниранку до 15 години дня, а вже після 18 години вечората в прохолодні ночі жуки ховалися в ґрунт на глиби-ну 0,5–2,5 см. Фітофаг пошкоджував рослини суниціз фази «висування квітконосів» до закінчення фази«закінчення цвітіння і утворення зав’язі», не надаючиособливої переваги їх сортовому походженню. Пару-вання особин розпочиналося відразу після виходу жу-ків на поверхню ґрунту і тривало до закінчення льотуімаго. Впродовж першої половини травня–кінець червнявідбувалося активне відкладання яєць шкідником уґрунт на глибину до 35 см. Потенційний запас однієїсамиці (у 2–3 прийоми) досягав 34–44 яєць; вона від-кладала по 12–17 яєць у ґрунт у декількох місцях. Від-родження личинок з яєць спостерігалося в ІІ-й декадітравня і тривало до кінця ІІІ-ї декади липня. Личинкижили в ґрунті до кінця серпня–початку вересня і жи-вилися рослинними рештками. Заляльковування роз-починалося з кінця серпня і тривало до половини ве-ресня. Через 15–20 днів з’являлися молоді жуки, щозалишалися зимувати в ґрунті (на необроблених ділян-ках) до весни наступного року. За відсутності прове-дення захисних заходів до 93 % квіток рослин у насад-женнях було пошкоджено цим видом, їх врожайністьзнижувалася до 65 %. Для зниження чисельностіцього виду необхідно застосовувати інсектициди«Моспілан», РП (0,2 кг/га) та «Каліпсо» 480 SC, КС(0,25 л/га).        It is showed the results of studies where the biological peculiarities of Epicometis hirta Poda. are ascertained in industrial plants of strawberries in the right bank of Forest Steppe zone of Ukraine.       It is established that beetles fly in warm sunny days the most intense from 10 a.m. to 15 p.m. and after 18 p.m. and in cool nights beetles hide in the soil in the depth of 0,5–2,5 cm.  Pest has started to harm plants of strawberry starting of phase «nomination of peduncles» to the end of phase «end of flowering and the formation of ovaries» without any preferring of varietal origin. Copulation of individuals was started immediately after beetles appearing on the soil surface and lasted until the end of the adults fly. During the first half of May till the end of June active pests’ eggs laying in the soil on a depth of 35 cm was observed. The potential production of one female (2–3 hours) has reached 34–44 eggs, she postponed 12–17 eggs in the soil in several places. Larvae hatching from eggs was observed in II-decade of May and continued until the end of the III decade of July. The larvae lived in the soil by the end of August – early September and was fed by plant remains. The pupation phase was started from the end of August and lasted until half of September. After 15-20 days there were young beetles that stayed wintering in the soil (in untreated plots) till the next spring. In time of absence of protective measures to 93 % of flower of  plants in plantations were damaged by this pest, their productivity was reduced to 65 %.         For decrease of this pest population it is required to apply insecticide Mospilan, RP (0,2 kg/ha) and Calipso 480 SC, (0,25 l/hа).

New data on the boundaries of the distribution range of the Lindholm rock lizard (Darevskia lindholmi), an endemic of the Crimean Peninsula, are presented. This petrophilous lizard inhabit a wide range of biotopes in various landscape levels of the Mountainous Crimea. The upper boundary of D. lindholmi distribution in the southwest of the Main Range of the Crimean Mountains reaches an elevation of 1,520 m a.s.l. (Ai-Petrinskaya Yayla, KemalEgerek Mountain), while on the other high uplands with altitudes above 1.5 km and colder climate (Babugan and Chatyrdag), the species was traced only up to 1,250–1,320 m a.s.l. The northern border of D. lindholmi range in the western part of the Crimean Mountains runs along the Outer Foothill Range (the right bank of the Alma River), while in the eastern part it corresponds the northernmost rocky massifs of the Inner Foothill Range to the north of 45º N latitude. Isolated marginal populations found in the forest-steppe or phrygana-steppe landscapes of the Foothills and arid Southeastern Coast differs significantly in their distance from the main habitat of the species, lizards’ abundance and density. A hypothetical history of the formation of the current range of the Lindholm lizard is discussed.

The purpose of the research was to study the effect of planting time on the formation of productivity of Hungarian sainfoin when grown for green forage. Methods are field, laboratory, statistical, correlation and regression relationships. Research results. It is established that under uneven humidity and high temperature regime in the year of sowing, Hungarian sainfoin formed two yields under spring planting date and one yield under summer planting date. In the second and third years of growth, no significant effect of the planting date on the stages of organogenesis of Hungarian sainfoin was found, where the maturity of the herbage was reached simultaneously. Productivity of Hungarian sainfoin was only conditioned by hydrothermal conditions, where the yield of green mass averaged 45.9—49.6 t/ha with crude protein content of 1.58—1.73 t/ha. At the same time, the highest dry matter yield of 10.25 t/ha and crude protein of 1.73 t/ha was provided by agrophytocenosis when sown on April 12. The productivity index of Hungarian sainfoin in the first year of life was determined, where the highest indicator was obtained during the early spring sowing period (29.04) – 7.85 kg/ha of dry matter per 1 hour of light day, whereas for the recommended summer sowing period was 1.13 kg/ha, or 6.9 times lower. The correlation equation between dry matter output, duration of daylight and the sum of precipitation from full shoots to the beginning of flowering in the first year of life is described. It is found that with increase of precipitation by 1 mm the dry matter output increases by 1.53 % and there is a tendency increase with increasing the length of daylight by 1 minute. Conclusions. It has been established that on gray forest soils of the right-bank Forest-Steppe, over two years of intensive use of the grass stand, regardless of hydrothermal conditions, Hungarian saifoin provided a stable forage productivity when sown in spring. Thus, dry matter yield was 9.38—10.25 t/ha with crude protein content of 1.58—1.73 t/ha. In particular, as for summer planting date, July 20 appeared to be the most effective planting date, which provided dry matter yield of 9.78 t/ha with crude protein content of 1.61 t/ha.

The article presents results of the long-term studies of the structure and production of agrophytocenoses, established on the coal mining dumps in the Kuznetsk basin forest steppe zone. Agrophytocenoses were established on the leveled dumps by seeding grasses and legumes. Another set of control agrophytocenoses was established by the same technic on zonal soil. Seeds were provided by the laboratories of the Central Siberian Botanical Garden SB RAS, Novosibirsk. After 30 yrs of observations it was found that agrophytocenoses on the coal mining dumps did not have initial stage, as well as stage of spontaneous species invasion. Elimination of Trifolium pratense and Arrhenatherum elatius from coal mining dumps phytocenoses took place 3-4 yrs later than from agrophytocenoses on zonal soils. Species did not eliminate totally, but remained in communities with increased or decreased relative abundances. Significant number of species displayed fluctuation, rather than succession in course of 30 yrs development on the coal mining dumps. These phytocenoses It was also found that agrophytocenoses on the coal mining dumps have high long-term production potential.
