Theoretical foundations of essential-oil-bearing plants' introduction is established including issues of selection, study and cultivation of source material. According to the conception, introduction is based on the search of theoretically possible terpenoids among genera and species studied. Schemes-matrixes of plants' hypoteticaly possible terpenoids search are compiled using Lamiaceae and Asteraceae families as examples.
Author reinvestigated plant cover in natural reserve « Yelanetsky steppe» (1675.5 ha, Mykolayiv region) after 10 years of fixing its original state (1997-2007). The main attention was focused on the absolutely protected steppe with no impact of human-induced fire (93 ha). Shrub-steppe communities with Сaragana frutex are spread here with increasing number of Crataegus monogyna, Rhamnus cathartica, Rosa corymbifera etc. Distribution of Stipa capillata, S. lessingiana, S. ucrainica, Festuca valesiaca has been nearly three times decreased on absolutely protected steppe. Being still dominated, these communities was added by relatively mesophytic communities of Poa angustifolia. In general, reserve steppe vegetation demutated only sporadically because of fires, especially in droughty 2007, wich caused their significant degradation. Postexarational demutation of fallow land was quite intensive and reached the stage of Poeta angustifoliae with the complex of forb communities and naturalized trees and shrubs from the surrounding hedgerows.
The results of study of floristic diversity of kurgans in the Pontic herb(-rich) grass steppe zone (according to Map of the Natural vegetation of Europe 2000: the west and central Pontic herb-grass steppe (M5) and west and central Pontic herb-rich grass steppe (M1) zones) in Mykolaiv and Kirovograd Regions, are presented. Twenty-nine kurgans higher than 3 m, distributed over an area approx. 9000 km2, were surveyed. The investigated kurgan flora contains more species than the flora of the barrows in the west Pontic grass steppe and desert steppe zones, being estimated at 439 species. The number of species on a single kurgan varied from 89 to 171 with 125,5 on average. Hemicryptophytes dominated in the kurgan flora (38,8%) of the Pontic herb(-rich) grass steppe zone, whereas therophytes prevailed in barrow flora in the steppe zones southwards. Phanerophytes were more numerous as well (8,7%). (Annuals and biennials constituted 35,1% of the kurgan flora. Most of them are synanthropic species, e.g. weeds derived from the surrounding fields. The total number of alien species (anthropophytes) reached 113. Archaeophytes and kenophytes comprised 23,5% of the kurgan flora.
A total of 19 syntaxa of higher rank were represented in all the kurgans studied. Species associated with steppe syntaxa such as Festuco-Brometea, Festucetea vaginatae, Polygono-Artemisietea and Galietalia veri comprised as much as 49,9 % of the kurgan flora. As in the case of the desert and grass steppes, species belonging to classes Festuco-Brometea and Stellarietea mediae were predominant in the herb rich grass steppe, which also confirmed the semi-natural character of the kurgan flora. The species of particularly high floristic value were: Adonis vernalis, Amygdalus nana, Anemone sylvestris, Astragalus dasyanthus, Crocus reticulatus, Elytrigia stipifolia, Galium volhynicum, Goniolimon tataricum, Hesperis tristis, Iris halophila, Limonium platyphyllum, Linaria biebersteinii, Ornithogalum kochii, Phlomis hybrida, Stipa capillata, S. lessingiana. The investigations carried out in the Pontic herb(-rich) grass steppe zone confirm that kurgans constitute refugia for the steppe flora. They are more or less uniformly distributed in the steppe zone, and could play an important role in the local restoration of the natural plant cover. Therefore, they should be put under protection as archeological and nature monuments.
The study shows that the impact of artificial short-cup photoperiod on plants in early stages of development, changes of the aminoacid exchange and the building of morphological elements are kept synchronous in the apical cone of spring wheat shoot.

The comparative structural analysis of the vascular aquatic flora in upper and middle parts of Southern Bug valley is presented. The flora comprises 106 species of 59 genera and 34 families. Patterns of aquatic macrophytes’ territorial differentiation within the river valley are elucidated.
There are 13 associations belonged to orders Phragmitetalia, Bolboschoenetalia maritima and Nasturtio-Glycerietalia in the Kremenchug reservoir. A classification scheme developed using Braun-Blanquet approach with coenotic analysis and distribution patterns of communities studied.
Using distribution of 122 species of lichens and location of the lichenoindication zones, estimation of the atmospheric air quality is made in 10 resort landscapes of Yalta amphitheatre. High atmospheric air quality is found in reserve «Yuzhnoberezhnye Dubravy», Nikitsky Botanical Garden and “Polyana Skazok” vicinity, and low atmospheric air quality – for the park landscapes of Yalta city embankment.
Feather-grass steppes in the Mokra Sura river basin was studied. Species lists are compiled for four formations of genus Stipa L. with 209 species from 126 genera and 36 families. A list of rare and endangered species is compiled as well with giving conservational status to all 28 species.
A method of computer synphytoindication was applied to clarify the impact of grazing, haying and total reservation on changes in ecotopes. The magnitude of some edaphic factors (humidity of soils, nitrogen and acid regimes) are justified by trustworthy differences on plots with different conservational regimes.
Data about finding of 24 rare species in Donets’k chain of hills are given (Ephedra distachya L., Cystopteris fragilis (L.) Bernh., Asplenium septentrionale(L.) Hoffm., A. trichomanes L., Aconitum rogoviczii Wissjul., Adonis wolgensis Steven, Anemone ranunculoides L., Pulsatilla pratensis (L.) Mill., Corydalis paczoskiiN.Busch, C. solida (L.) Clairv., C. marschalliana (Pall. ex Willd.) Pers, Cerastium pseudobulgaricum Klokov, Mercurialis perennis L., Allium lineare L., Gagea bohemica (Zauschn.) Schult. et Schult. f., Fritillaria ruthenica Wikstr., Tulipa ophiophylla Klokov & Zoz, T. quercetorum Klokov & Zoz, Hyacinthella pallasiana (Steven) Losinsk, Ornithogalum boucheanum (Kunth) Asch., Scilla siberica Haw., Crocus reticulatus Steven ex Adams, Iris pumila L., Stipa capillata L.). The age structure of the coenopopulations of Fritillaria ruthenica and the Hyacinthella pallasiana is elucidated. Additional nature areas in Bila River valley are recognized for establishing new protected territories.
The article presents the data on the new species of Crimean bryophlora, collected in the plain part of the Crimea in 2003-2009. Such species as Acaulon triquetrum (Spurse) H. Müll., Bryum klinggraeffii Schimp., B. kunzei Hornsch., B. moravicum Podp, Dicranella heteromalla (Hedw.) Schimp., Entostodon hungaricus (Boros) Loeske, Microbryum curvicollum (Hedw.) Zander, Physcomitrium pyriforme (Hedw.) Brid., Protobryum bryoides (Dicks.) Jguerra & M.J. Cano, Pterygoneurum kozlovii Laz., Sciuro-hypnum oedipodium (Mitt.) Ignatov & Huttuman, S. starkei (Brid.) B.S.G. are found in the Crimean Peninsula for the first time.
The list of lichen species of the geological reserve «Skeli Modru» includes 55 species of the lichens and 3 species of lichenicolous fungus which belong to 29 genera and 18 families. The main part of the local lichenobiota is considered to be rare having only a few localities in Ukraine.
The list of the lichens and lichenicolous fungi of the “Elanetsky step ” Nature Reserve includes 163 species which belong to 66 genera, 23 families, 8 orders and group of Anamorphic fungi. 49 species of lichens and 8 species of lichenicolous fungi are revealed to be new for reserve. Data about ecology and frequency occurrence of the lichen forming and lichenicolous fungi are provided.
