The paper presents the results of an introduction study of four species of the genus Echinacea Moench from the collection of aromatic and medical plants of the Nikitsky Botanical Garden: E. angustifolia DС. , E. pallida (Nutt.) Nutt. , E. tennesseensis (Breadle) Small and E. purpurea (L.) Moench. Morphological and biological features of these species were identified in order to determine the prospects of their cultivation in the conditions of the Southern Coast of the Crimea. A positive interspecific dependence of the number of inflorescences (baskets) on a plant with the length of the growing season (r=0.92) was established. An intraspecific assessment of the morphometry of inflorescences, such as their diameter, the length of the lingual flowers and the height of the flower bed, showed that E. purpurea has a tendency to negatively correlate these indicators with their number on the plant. Among the studied species of the genus Echinacea, according to the complex of thirteen morpho-biological and economically valuable traits, two species differ in adaptive advantage - these are E. purpurea and E. tennesseensis , and the best samples are No. 15309 and No. 6106 with an aboveground mass yield, respectively, 1.20±0.21 kg/plant and 0.92±0.19 kg/plant. E. pallida is characterized by cumulative signs of drought resistance, it is a short growing season equal to 124±4.1 days and a narrow-lanceolate leaf blade shape (index - 9.6), which allows this species to form a significant yield of aboveground mass (0.86±0.17 kg/plant) in the arid conditions of the subtropical climate of the Southern coast of the Crimea.

The article presents the results of a long-term research on the introduction study and evaluation of cultivars of tea-hybrid roses introduced and selected by the Nikitsky Botanical Gardens to determine the possibilities of their use in floriculture of the Southern Coast of the Crimea. The research was conducted in the period from 1955 to 2014. The material for the study was 679 cultivars of garden roses from the tea-hybrid garden group of the collection of the Nikitsky Botanical Gardens. As a result of a comprehensive study, 400 cultivars are recommended for use in the floriculture of the Crimea. The main options for this use becomes the growing of tea-hybrid roses in the open ground for gardening purposes in bush and tree-shaped forms, as well as the growing cultivars for cutting in both open and protected ground. The biological features of the cultivars, which determine the possibility of different types of the use and the cultivars, that have these features were identified: 400 cultivars were recommended for use in landscaping in bush form, 45 cultivars - also in tree-shaped form, 226 cultivars are promising for cutting in the open ground and 107 cultivars - for forcing and cutting in greenhouses. The main methods of propagation of cultivars of tea-hybrid roses under the conditions of the Southern Coast of the Crimea are budding and rooting of green and hardwood cuttings. The optimal timing for propagation by each of these methods is indicated. The best rootstocks for budding were identified, depending on the type of their use in floriculture.

The dependence of the growth intensity of Juniperus excelsa M. Bieb on some environmental factors in the greenhouse conditions of the Southern Coast of the Crimea was studied. Vegetation and trunk diameter growth (d,%) started after March 15. There are two growth peaks: the first growth peak (15.03.–27.07.) led to an increase in d,% by 7.12% (0.053% per day) – with a slowdown in growth (28.04 –27.05) and (13.07 – 25.07) associated with a decrease in air temperature. The second – (12.09 – 18.11) led to an increase in d,% by 5.06% (0.075% per day), while also slowing growth at this time (05.11.–14.11.) was observed. After the second phase of active growth (14.11), there is an access to the growth plateau with the resumption of the growing season only in March next year. During the studied vegetation period (2019), the increase in trunk diameter d,% was 12.18% or 1.89 mm. Optimal conditions of maxima and boundaries of optimal regions for the first growth peak: d%=f(I,Ta) – Ta=22–28°C, I=500–800 mkmol/m2s, for d,%=f(I,Da) – Da=1.8–2.3 kPa, I=500–800 mkmol/m2s. For the second growth peak: d%=f(I,Ta) – Ta=22–26°C, I=400–750 mkmol/m2s, for d,%=f(I, Da) – Da =0.3–1.2 kPa, I=400–750 mkmol/m2s.

Estimate climatogenic changes in phenorhythms of Olea europaea L. during the growing season in Southern coast of the Crimea carried out. The study used data of olive trees phenological observations and data climatic parameters during 1947–2020. It was established that in the ‘Nikitskaya’ cultivar during studied period of climate change the steady bias tendency to shift to earlier budbreak dates and fruit maturity has been observed since the 80s, the flowering has been since the 90s of the XX century, first leaves separated has been since the beginning of the XXI century and it differs in the highest rates. For the last 2001–2020 the tendency to shift earlier spring phenophases of budbreak and first leaves separated has increased 1.5–2 times. Phenological models using as input variable temperature and photoperiod were developed to predict dates beginning of full flowering ‘Nikitskaya’ olive cultivar. Forecast accuracy amount to 2.7–4.1 days. The expected future change those dates to end of XXI century are also shown.

The dependence of the growth rate of Arbutus andrachne L. on some environmental factors was studied under the conditions of the Southern Coast vegetation experiment in different periods of the species vegetation, which made it possible to find the optimal and limiting conditions for its growth. In March, vegetation began at an average daily air temperature of 3.5 – 7.50 °C and the increase in stem diameter was approximately 0.42 % (0.09 mm), at the second stage (April-May) – 3.7 % (0.58 mm) with a further exit to plateau. In July - August, two sections of the d % change are observed: the first section is from July 27 till August 19 - intensive growth of d % by 12.58 % (1.961 mm), the second section after August 19 – access to the growth plateau, which is associated with an increase in air temperature to 30-35 °C. In September-October, two sections of the d % change are observed: the first section lasted from September 01 till September 15 - intensive growth of d % by 3.55 % (0.582 mm), the second section after September 15 – exit to a plateau of growth, lowering the air temperature to 8-10 °C and the end of the growing season. In November, an increase in trunk diameter was not observed. The optimal environmental factors were: in March-May, Ta = 20-2 °C, Da = 0.4-1.2 kPa, I = 300-900 mmol / m2s; July-August, Ta = 22-28 °C, Da = 1.4-2.5 kPa, I = 500-1000 μmol / m2s; in September-October, Ta = 16-25 °C, Da = 0.3-1.5 kPa, I = 400-800 μmol / m2s, respectively. The results of our experiments allow us to compare the ecological and physiological characteristics we obtained with the climatic conditions of a particular region and evaluate the possibilities of introducing it into other regions.

The aim of the work is to supplement and clarify the annotated list of vascular plants of “Castel” nature reserve on the Southern coast of the Crimea. Methods. The work is based on the results of long standing field research, which was carried out by the traditional route-reconnaissance method, analysis of YALT herbarium materials and data from literary and Internet sources. Arealogical and biomorphological characteristics of species are given according to "Biological Flora of the Crimea" by V.N. Golubev, biotope coding according to EUNIS habitat classification. The nomenclature of taxa corresponds to the " Spontaneuos flora of the Crimean peninsula" by A.V. Yena and to international databases Euro+Med PlantBase, The Plant List, Catalog of Life. Results. An additional annotated list of vascular plants of “Castel” nature reserve has been compiled, including 152 species, subspecies and cultivars from 97 genera of 38 families, of which 53 genera and 11 families have also not been cited for this territory before. Arealogical, biomorphological, biotopic and sozological characteristics of the taxa are given. As a result of a critical analysis of the list previously published by E.S. Krainyuk, four species were redefined, two species were proposed to be excluded from the flora of the specially protected natural area, several taxa are considered doubtful. Conclusions. The list of vascular plant taxa in “Castel” nature reserve has been supplemented with 11 families, 53 genera, and 152 species, subspecies, and cultivars; several species from the previously compiled list have been proposed to be excluded or considered doubtful. Thus, the flora of the protected area includes at least 425 species from 68 families. For the first time, the biotopic characteristic of the flora of the reserve was established.
