Наведено результати первинного інтродукційного випробування квітниково-декоративних рослин, що належать до представників роду Lupinus L. в умовах Поділля. Проаналізовано видовий склад роду Lupinus та визначено перспективність їх використання для озеленення різних об'єктів зони Поділля. Для диференціації рослин відповідно до сфери їх можливого використання наведено морфометричні показники найперспективніших представників цього роду. Встановлено, що всі досліджувані види викликають інтерес як потенційно цінні об'єкти для збагачення асортименту вітчизняних декоративних рослин та є перспективними для поліпшення стану парків, скверів, садків зони Поділля. Враховуючи високі декоративні якості цих видів та широкі можливості їх застосування, квітниково-декоративні рослини представників роду Lupinus L мають важливе значення для садівництва та для поповнення асортименту декоративних культур нашої держави. З'ясовано, що природні можливості представників роду Lupinus, пластичність до зміни їх життєвої форми, висока якість за сукупністю ознак, що визначають їх декоративність, характеризує досліджувані рослини як джерело для інтродукції і збагачення асортименту декоративних культур в Україні. Отже, інтродукція представників роду Lupinus для озеленення дасть змогу значно розширити асортимент декоративно цінних рослин та збагатити культивовану флору зони Поділля та України загалом.

In the Podillya area, the most promising for greening different objects is the Lupine perennis L. and Lupine Polyphyllus Lindl. For creation of modern garden compositions of the park zone of Vinnytsia National Agrarian University the most appropriate are the varieties: Lulu-Russell, Minaret, Albus, Fireworks, which were well adapted to the growing conditions, were practically not affected by pests and diseases, were sufficiently resistant to environmental conditions. According to the flowering phase study, it was found that the highest flowering duration was observed in perennial lupine plants. In determining the suitability of the plants studied by us for their use in landscaping, their assessment of the complex of economic and biological indicators in accordance with the State Methodology of Variety Testing was carried out. Their high score on a set of criteria testifies to the prospect and suitability for cultivation in Podillia conditions, as well as the value for different uses: flower beds, ridges, mixboards, landscape type compositions and their smaller variants imitating natural groups.

Based on studies of substrates for mulching raspberry varieties Veresnevi zori revealed the following: for mulching with straw or sawdust, the onset of the phenological phases of raspberry plants occurs later, compared to the cultivation without mulching; a greater number of root shoots and shoots are provided by growing raspberries without mulching, but a higher shoot height (133.2 cm) and shoot shoots (123.9 cm) distinguishes the straw mulch variant; the maximum yield of raspberry berries of the Veresnevi zori variety is provided by mulching with sawdust - 94.5 c/ha, which is 3.1 c/ha more than straw mulching and by 16.9 c/ha the control variant. The share of ripe berries in the yield by mulching sawdust increases to 81.5%, which is 4.4% more compared to straw mulching and 9.1% more compared to the control variant; the highest average weight of berries and maximum weight of 5 berries was obtained by mulching raspberries with sawdust; for raspberry mulching with sawdust, the profitability of raspberry berries production is the highest -258.9% and 4.3% less than straw mulching. The results of the work are recommended to be used during research and in practice.

Annual aster, also called China aster (Callistepsus chinensis (L.) Nees) is one of the priority ornamental flower plants for the introduction both in Ukraine and throughout the world. Domestic and foreign scientists are diverse in the study of this plant. Most of the works published during the last decades are devoted to the study and search for the most favorable agrotechnical techniques for aster cultivation under different conditions. The research was being carried out during 2016‑2017 on the territory of the Bio-stationary of Vinnytsia National Agrarian University with partial subsequent data processing at Bila Tserkva National Agrarian University. The purpose of the study was to identify the most adapted and resistant samples among the collection cultivars of China aster for their further breeding and greening of various objects of Vinnytsia region. The methods of field and laboratory research were applied in accordance with the basic methodological requirements. The prospects of growing cultivars of China aster (Callistepsus chinensis) in the green space of Vinnytsia region were analyzed. The demand for new cultivars of different groups of annual aster in ornamental gardening and the need to develop decorative cultivars resistant to diseases and adapted to the environment was proved. For the first time, biomorphological features of Chinese asters (Callistepsus chinensis), methods of reproduction and the most promising cultivars for their growing under conditions of Vinnytsia region and their further use in landscaping of various objects were investigated. A collection of cultivars of different groups of Chinese aster on the territory of the collection site of Vinnytsia National Agrarian University was produced and unified. Due to high ornamental qualities, economic and biological qualities of the studied cultivars, all of them are evaluated as well adapted to the edaphic and climatic conditions of Podillya and they are recommended as objects intended for the replenishment of the assortment of plants for greening, collection and exhibition funds as well as breeding activities. A diversity of colours and forms of inflorescence, various shapes and height of the bush enable to use China aster widely in the single linear plantations, group plantations, for the arrangement of mixborders and plant beds, on the rocky landscapes and borders, to create groups and flower beds.

This article analyzes the main problems of use and compositional application of different types of magnolias in Vinnytsia. In the research material of the article we conducted an analytical review of the species diversity of magnolias. We found that most acclimatized species are highly decorative, the highest rate of decorativeness is characteristic of Magnolia Soulangeana Soul. (48 points), and the lowest in Magnolia obovata Thunb. (46 points). As a result of research it was found that the range of magnolias in Vinnytsia is very poor and is represented mainly by such species as: Magnolia kobus D.C., Magnolia obovata Thunb., Magnolia Soulangeana Soul., Magnolia acuminata L., Magnolia tripetala L.; It is investigated that in the compositional application of magnolias are used in Vinnytsia mainly for single or group landscaping of buildings; As a result of research, it was found that due to their morphobiological, ecological properties and decorative qualities, the possibilities of using magnolias can be much wider and knowing their winter hardiness, you can use a wider range of species in our conditions. It is established that less decorative, but more stable species are used for street landscaping (M. kobus DC, M. kobus Sarg. Var. Borealis., M. x loebneri Kache., M. acuminata L., M. salicifolia (Sieb. Et Zucc.) Maxim., M. x kewensis Pearce., M. biondii Pamp., M. cylindrica Rehd. Et Wils., Etc.). We have found that the most popular varieties of magnolia are Betty, Merril, Lennei. According to the results of the study, we found that the lowest prevalence rate is characteristic of Magnolia Loebneri "Merrill" (7%), and the highest in Magnolia x soulangeana "Lennei" (14%). It is established that these varieties have a number of advantages, among which it should be noted: plants are suitable for growing in Ukraine almost everywhere, cold- and frost-resistant; compact, characterized by slow growth; flowers have a decorative look, long retain freshness, are characterized by a wonderful aroma.
