The research material was 12 wild roses belonging to 4 sections: Canina Crep, Cinnamomeae DC, Luteae Crep, Pimpinellifoliae DC. The research was carried out using the methods of the Main Botanical Garden, floral and geographical analyses — according to Hrzhanovsky. A caliper was used to measure the length and diameter of 10 fruits. For the analysis of statistical data, the MS Excel table processor and the integrated MATLAB mathematical package were used.Results. The article presents the results of a study of species of roses in the Stavropol Botanical Garden of various geographical origin. The study involved 12 species belonging to 4 sections. The features of growth and development of plants in new soil and climatic conditions are revealed. The dates of the beginning of the main phenological phases andtheir duration have been established: spring regrowth of shoots, budding, beginning and end of flowering, fruiting. In the studied species of roses, the growing season begins in the first — second decade of March, flowering occurs in late May — early June, the fruits ripen in August — September. The dependence of the timing of the beginning of flowering in the studied roses on the dynamics of the accumulated average daily air temperatures and the sum of effective temperatures above 5 °C was revealed. Mathematically, it was proved that the lower limit of the air temperature required for the beginning of flowering of species of roses is +16 °C, when the sum of the average daily temperature air St° = 1007.75–1069.48 °С and St эф > 5 °С = 530.75–594.75 °С are accumulated. Early flowering species of roses include Rosa foetida Herrm., R. pendulina L., R. pimpinellifolia L., late flowering — R. caudata Baker and R. corymbifera Borkh. The shortest flowering period is in R. caudata Baker, R. jacutica Juz. and R. kamtschatica Vent. Representatives of those types mostly bloom once. Their flowers are formed on biennial and more mature shoots. The flowering period is 13–23 days. Rosa rugosa Thunb. blooms again, its flowering period is extended and long — from 40 to 48 days. All species of roses form fruits. The longest fruits are in R. pendulina L., R. caudata Baker, R. rugosa Thunb., R. corymbifera Borkh. and R. canina L., and large ones — in R. rugosa Thunb., R. marretii Lev. and R. roxburghi Tratt.

Relevance. The study of the timing and duration of individual phases of the development of strawberry cultivars of different ecological and geographical origin in these climatic conditions is of great practical importance. The purpose of the study was the determination of the timing of the main phenophases of introduced strawberry cultivars in the Orel region, the compliance of the phenorhythms of the studied cultivars with climatic conditions, as well as the ranking of the cultivars by the terms of flowering and maturation.Methods and materials. The article presents the results of phenological observations for the period 2016-2019. 34 strawberry cultivars of domestic and foreign selection were studied. The research was carried out at the VNIISPK site of primary variety study.Results. Based on long - term observations, on the time of entry into the flowering and fruiting phase, the cultivars were ranked into early, medium and late-maturing. The influence of effective temperatures on the onset of phenophases was analyzed. The sum of effective temperatures necessary for the beginning of flowering of strawberry cultivars of different maturation periods in the conditions of the Orel region was determined. For the onset of strawberry flowering, it takes from126.68 to 260.37°effective temperatures. Early cultivars need the sum of effective temperatures of 126.68-197.55°, cultivars of middle maturation need 146.31-225.44°, late cultivars - 159.93-260.37 depending on the year of study. Fruiting occurs at the sum of effective temperatures in early cultivars from 351.73°C to 465.43°C, in middle-maturing cultivars from 390.96 to 535.44°C, in late-maturing cultivars from 450°C to 649°C.

Purpose. To reveal the peculiarities of the seasonal rhythm of growth and development of Itoh Group peony cultivars in the conditions of the M. M. Hryshko National Botanical Garden National Academy of Sciences of Ukraine. Methods. The objects of research were plants of 24 cultivars of Itoh Group peonies. The research was conducted on the experimental field of the Department of Flowering and Ornamental Plants of the M. M. Hryshko National Botanical Garden National Academy of Sciences of Ukraine during 2017–2020. The sum of effective temperatures was calculated by summing the daily air temperatures reduced by the biological zero.                 Results. The phenological phases of Ito Group cultivars growth were determined. Phenological spectra for different groups are presented. It was determined that the flowering of early cultivars: ‘First Arrival’, ‘Hillary’, ‘Julia Rose’, ‘Morning Lilac’, ‘Old Rose Dandy’, ‘Sonoma Apricot’ starts at the sum of effective temperatures ≥ 400 °С. The middle group hybrids bloom when the sum of temperatures reaches 450 °С. This group includes: ‘Bartzella’, ‘Callie’s Memory’, ‘Cora Louise’, ‘Lollipop’, ‘Scarlet Heaven’, ‘Sonoma Velvet Ruby’, ‘Yellow Dream’, ‘Yellow Emperor’, ‘Yellow Heaven’, ‘Yellow Waterlily’. Late flowering group includes: ‘Border Charm’, ‘Garden Treasure’, ‘Kopper Kettle’, ‘Pastel Splendor’, ‘Prairie Charm’, ‘Viking Full Moon’, ‘White Emperor’, ‘Yankee Doodle Dandy’; accumulation of effective temperatures above 500 °С is an essential requirement for their flowering. Conclusions. Itoh Group cultivars successfully pass all phases of seasonal development and manage to complete the growing season. Cultivars belong to the spring-summer-autumn-green phenorhythmotype. The onset of the corresponding phenological phases in peonies of the studied group of cultivars requires a certain sum of effective temperatures. Plant outgrowth begins on March 23 – April 2, when the sum of effective temperatures ranges from 20–40 °С. The flowering of varieties characterized as late spring, lasts 6–9 days ± 3–4 days, depending on the varietal characteristics and the year of cultivation. A rapid increase in the sum of effective temperatures up to 700 °C shortens the flowering phase by 4–5 days. An assortment of early (May 22–25 ± 2–3 days), medium (May 26–28 ± 3–5 days) and late-flowering (May 29–31 ± 4–6 days) cultivars has been selected, what ensures the continuity of peony flowering during two months.

The results of a long-term introduction study of Hungarian lilac, an endemic of the Carpathians and Transylvania, cultivated in the South Ural Botanical Garden-Institute of the UFIC RAS, are presented. The study used phenological data from 2005-2020. The beginning of the growing season for Hungarian lilacs falls on the period from April 14 to 30, flowering is observed annually in late May and early June. The duration of flowering over the last 5 years (2015-2020) averaged 16 days, which is 6 days shorter than the flowering period of this type of lilac in 2005-2009. The likely reason for the shortened flowering period is climate change. Complete lignification of the shoots of Hungarian lilac occurs in the second half of July. In Ufa, Hungarian lilacs have fruiting (seeds begin to ripen from September 18 to 27), as well as the presence of self-seeding. The beginning of leaf fall (the end of the growing season) coincides in timing with the beginning of seed ripening. All phenological phases of Hungarian lilac retain their sequence every year. Winter hardiness is usually I point (plants are absolutely winter hardy). The phenological atypicality index is -0.250 or 4 points according to Zaitsev, which means that the phenology of the species is fully consistent with the climatic conditions of Ufa. Thus, the introduction of Hungarian lilac in the South Ural can be characterized as successful and promising.

Abstract. Purpose. The study is aimed at a comparative analysis of apricot cultivars of various ecological and geographical origin of the genetic collection of the Mountain Botanical Garden by the initial phenological phases of flowering and vegetation in order to determine their degree of interconnection and determine the autochthonous varieties and forms of the Dagestan apricot. Methods. The study is based on the methods of phenological observations in accordance with generally accepted methods with their own additions. Results. It was revealed that the appearance of red bud varieties varied in a wide range (March 28 – April 21), on average, on April 6. The white bud phase was observed in the first and second decade of April from the 1st to the 25th day of the month, and the beginning of flowering from April 5 to 28. Vegetative buds begin to wake up as a whole later than generative ones, with the exception of varieties and hybrids bred from crosses with plum and alpine plum. Beginning swelling buds, flushing buds and leaves in the second and third decade of April, on average on April 11, 21 and 25, respectively. Correlation analysis showed the presence of a positive correlation between the majority of generative and vegetative traits of varieties and forms of apricot, significant at the level of P ≤ 0,05. An inaccurate correlation was found between the trait “bud swelling” and all generative traits. According to the results of cluster analysis, the proximity of most of the cultivars of Dagestan origin to each other was established, with the exception of the Khonobakh variety and its varieties, which turned out to be closer to the Central Asian varieties, which is probably due to its allochthonous origin. The scientific novelty of the study is to assess the phenological phases of flowering and swelling of apricot cultivar leaves under the conditions of the Tsudakhar experimental base showed that the majority of Dagestan cultivars are early flowering (13 samples from 22) and medium (7), while in European and Central Asian prevail varieties of medium and late flowering.

The study reports results of research carried out from April to October during 1988–2016 at the Botanical Garden of Petrozavodsk State University (South Karelia, middle taiga subzones). Three introduced species of the genus Larix (Larix sibirica Ledeb., L. leptolepis (Sieb. et Zucc.) Gord, and L. dahurica Turcz. ex Trautv.) were studied. The growth of shoots and needles in different species begins, reaches its culmination, and ends almost simultaneously, differing by no more than one week across the species. L. sibirica shows the highest growth rate. The timing of growth, culmination, and the dynamics of growth of shoots and needles are largely determined by variations in precipitation, temperature, and humidity. The direction and strength of such an effect may vary from year to year. The dates of phenological phases of the Larix species studied here are chiefly determined by the air temperature in the current growing season and the dates of formation of wintering buds in the previous growing season. Bud swelling and opening begins almost simultaneously in the studied species. Most of the other phenological phases begin and end earliest in L. sibirica and latest in L. leptolepis. All the studied species, primarily L. sibirica, are promising for residential landscaping and creation of artificial plant communities in Karelia

The results of 35-year research of the introduction of East Asian climbing honeysuckles of the subgenus Chamaecerasus Rehd. in the Right-Bank Forest-Steppe of Ukraine and their role in optimizing the structure of phyto- cenoses of the The National Dendrological Park «Sofiyivka» of the NASU were presented. It was found that the climatic conditions of the introduction area have significant differences between climate indicators (thermal regime indicators and others) with the climatic conditions of natural habitats of climbing honeysuckles species of the subgenus Chamaecerasus, which negatively affect the rhythm of development and flowering and fruiting of introduced plants. It was determinated that the generative period of climbing honeysuckles of the subgenus Chamaecerasus in the arboretum occurs at 4–6 years of age. Most of the introduced honeysuckle was characterized by good (4 points) and satisfactory (3 points) flowering. Representatives of the subsection Breviflorae Rehd. were characterized by long and remontant flowering. It was found that the dynamics of daily fertility of honeysuckles pollen from different areas is closely related to the daily course of flower bloom- ing and daily flight activity of pollinating insects. The duration of the period of fruit formation of introduced honeysuckles depends on the time of the beginning of flowering of species and their geographical origin. Determined amount of positive temperatures above 0 °C required for mass ripening fruit honeysuckles different geographical origin. The plants bear fruit single fruits with empty seeds (ball bearing 1). The collection of climbing honeysuckles of the subgenus Chamaecerasus was created in the National Dendrological Park «Sofiyivka» of the NAS of Ukraine, it has significant scientific and informative value as collector' s stuff is valuable gene pool for further breeding work. The optimal forms of conservation and cultivation of biodiversity of round honeysuckle of the genus Lonicera L. in the one-species gardens and other artificially created phytocenoses have been determined.

In the soil and climatic conditions of the Right Bank Forest-Steppe, regardless of the action of abiotic and biotic factors during the growing season, high adaptability of alfalfa was established for different geographical origins, namely the natural zone of the Forest-Steppe, Polissya, Steppe Ukraine and Serbia. It was found that under the weather conditions of 2016 year alfalfa varieties reacted differently to changes in temperature and moisture during the growing season. It is important to note the effectiveness of phosphorus-potassium fertilizers applied directly to alfalfa coverless method of sowing. In the year of sowing, alfalfa formed a powerful herbage and provided two slopes with a yield of green mass at the level of 20,13-29,80 t/ha with a dry matter yield of 4,80-6,69 t/ha. For the second year of vegetation, alfalfa was carried out according to the regimes, which considered the phases of growth and development (budding, beginning of flowering and flowering). In the first mode of cutting management (all slopes in the budding phase) it is advisable to identify three varieties of Unitro, Nasoloda and Rosana, which provided a gross dry matter of 10,41-10,48 and 2,29-2,31 t/ha of crude protein. The productivity of alfalfa increased with late term cutting - at the beginning of flowering and a combination of slopes (3rd mode). The dry matter yield was 11,40-12,62 and 2,35-2,51 t/ha of crude protein (second regime) and the indicators increased under the third regime, especially dry matter 13,58-15,80 t/ha and decreased to 2,37-2,41 t/ha of crude protein. The increase in dry matter of the second mode increased by 9,5-23,1% and crude protein by 2,6-20,5%, and in the third mode of use of alfalfa it was 2,3-11,2%, compared to the mode of mowing the grass in the budding phase. During the third year of vegetation under favorable agroecological conditions for growth and development of alfalfa plants, the studied varieties provided four slopes regardless of the mode of use of grass with a dry matter yield of 15,43-20,58 and 3,21-4,02 t/ha of crude protein. During the second and third years of vegetation from the studied modes of use of alfalfa grass for fodder purposes, the highest yield of crude protein 5,27-6,53 t/ha varieties provided for the alienation of crops at the beginning of the flowering phase, which was on average 6,0-7,1% higher than when mowing all slopes in the budding phase and a combination of slopes in the phases of growth and development (3rd mode). Thus, in the conditions of the Forest-Steppe of the right bank on gray forest soils alfalfa, regardless of geographical origin, adapted to growing conditions and provided stable productivity indicators regardless of the regime of grass use with observance of elements of cultivation technology.
