According to the results of long-term monitoring (1974–2013) on permanent sample plots of the Institute of Ecology of the Carpathians National Academy of Sciences of Ukraine, in an ecosystem dominated by Juniperus communis, patterns of self-recovery (regeneration) of the population structure Soldanella hungarica after local destruction of herbaceous vegetation were examined. It was established experimentally that such small-scale effects do not create the preconditions for the further destabilization of the population. But they initiate the mobilization of  reserve S.hungarica  population in adjacent areas. The relationship of individual responses and group effects in the processes of self-recovery is shown. It is concluded about imperative importance of vitality of the local population regeneration of S.hungarica. Though it is still not fully predictable process that has been continuing for several decades.

We propose to make an ecological evaluation of plant communities based on their phytosociological spectra. Under the phytosociological spectrum we understand ratios of representation in the general species composition of a cenosis of species relating to different classes of the Braun-Blanquet system. We demonstrate that the first class of the phytosociological spectrum makes up from 22% to 45%. This indicates a transitional character of the flora of the studied plant communities. We propose to characterize such communities by similarity of their three first classes of the phytosociological spectra, rather than by characteristic species. We made ordination of the plant communities by phytosociological spectra, in which the axes represent classes according to Braun-Blanquet. We demonstrate that phytosociological spectra is changed along gradients of ecological factors. The ecological optima for some Braun-Blanquet classes were estimated using phytoindication data. 

Based on results of comparative ITS2 secondary structure sequence analysis from the nuclear-encoding ribosomal genes, species status was tested from subalpine population from Ukrainian Carpathian region that were identified using morphological criteria as Swertia alpestrisBaumg. ex Fuss. It was found that at the secondary structure ITS2 Swertia alpestrishas not differences from species of other populations, that were identified as Swertia perennis L. The taxonomical status of Swertia alpestris are discussed.

The article describes a decorative form of B. thunbergii «Rose Glow» (deciduous thorny shrub to 1.5 m in heigh arched inclined shoots), which was first studied in the south of Ukraine (based on Botanical garden of KSU materials). The types of wintering buds and determined their capacity are highlighted; the embryonic phase of development of leaves and especially the formation of shoots species is analysed; the anatomical structure of the stem: primary and secondary structure, identified is studied and spare nutrients are defined.

On the flood plains meadows of the river Psel, that is used as pastures and haymakings, the features of productional process and  growth of invasion species of Stenactis (Phalacroloma) annua (L) Cass. were studied. The analysis of reproduction of this species is conducted. The vitality structure of populations of Stenactis (Phalacroloma) annua (L) Cass. is established  on pascual  and fenisicial  gradients.

For the first time the surface ultrastructure of leaf epidermis of 10 species of the genus Hieracium in the flora of Crimea was studied using SEM. Both common (amphystomatic features, anomocytic type of stomata, longitudinal arrangement of stomata, cuticle roll around stomata, arrangement of wax deposits) and specific characteristics of the leaf ultrastructure of the studied species have been revealed. Most of them are additional diagnostic characters on the sectional level (surface relief type, arrangement of stomata relative to the level of basal epidermal cells, presence and type of trichomes; amount of wax deposits; cell contours) and the species level (surface relief type; localization of trichomes; cell contours). The homogeneity of H. sabaudum was set. 

In the surroundings of the four factories in the city of Mykolaiv (Ukraine) research was carried out  and the content of heavy metals – Cu. Zn, Cd, Pb  in soils and gametophyte of moss Bryum argenteum was analysed. Also the coefficients of accumulation of heavy metals in soils were analyzed at surrounding territories of factories of Mykolaiv  city (Mykolayiv Alumina Plant, Research and Production Complex of Gas Turbine "Zorya"-"Mashproject", JSC "Damen Shipyards Ocean" and Shipyard named after 61-Communards) 1-1,5 times higher than coefficients of accumulation gametophyte of investigated moss. The least contaminated in comparison with conditionally pure area is the territory and the surroundings of the factory of 61-Communards. These data confirm that this type of moss refers to indicator plants.

The 127 species of lichenized and 5 species of lichenicolous fungi are recorded. Lecanora atrosulphurea (Wahlenb.) Ach.  is new for the lichen biota of Ukraine and 55 species are new for «Kam`yani Mogyly» as branch of the Ukrainian Steppe Reserve. 14 previously reported lichen species were excluded from the list as misidentified. Each species include  about synonyms, substrates and herbaria where they deposited. 

Based on the holotype review, own materials and literature in the article data about the distribution and ecological features of rare species of fungicolous fungi – Albertiniella polyporicola (Jacz.) Malloch et Cain are summarized. The history of this species study, the complete nomenclatural characteristics, revised description and original illustrations are presented. At the first time it is reported about finding of A. polyporicola on the basidiomata of Ganoderma resinaceum Boud.

The communities of the association Sagino procumbentis–Bryetum argentei Diemont et al. 1940 in urban ecosystems of Pyryatyn (Poltava region) and Kyiv are studied. The typical and new subassociations S.-B. marсhanthietosum polymorphae Kovalenko 2013subass. nova are distinguished. This syntaxa are floristically, coentically and physiognomically distinct. The subassociations are different in dimension of ecology factors. The features of ecology, phenology, coenotic, biomorphological and geographical structures of the association make a problem of including association Sagino procumbentis–Bryetum argentei in system of high-level syntaxa. In results of floristic parsimony of phytocoenons from Isoëto-Nano-Juncetea and Polygono–Poëtea annuae classes the need of including association in system of the last classes is outlined.

During 2007-2013 years 103 species of agaricoid macromycetes from 51 genera, 20 families, 3 orders (Agaricales, Boletales і Russulales) of class Agaricomycetes аre revealed. The article provides the list of fungi species with distribution to ecotops of region. Taxonomic analysis, distribution to ecological trophical groups, determination properties and taxonomic indexes of mycobiota are reported. The similarity of species composition from different ecotops are presented. Novelty of macromycetes species for the Nоrthen-Western part оf the Black Sea region and steppe region of Ukraine are shown.

The paper summarizes the results of long-term study of Caucasian persimmon in the southern region of Ukraine in terms of its economic use as an ornamental and fruit crops as well as rootstock for other types of persimmons and their hybrids. In the southern region of Ukraine Caucasian persimmon may find practical use as rootstock for eastern persimmon and its hybrids only in places where the absolute minimum temperature is not lower than – 18–20 ˚ C: the Southern coast of Crimea. In colder climates it is better to use persimmon Virginia as a rootstock. The usage of Caucasian persimmon as fruit crops in the southern region of Ukraine is unrealistically primarily because of its low hardiness. Persimmon Virginia is more likely for this purpose; it is more winter-hardy and fruitful.

Studies on the development of preservation methods for the representatives of Orchidaceae Juss. family, whose natural habitats and numbers are considerably decreasing are very urgent today. Along with the traditional techniques of plant preservation ex situ biotechnological methods used for these purposes are becoming more and more important. These work investigations dealt with the development and improvement of the methods of isolated orchid tissue culture of Ukraine flora in order to apply them in the system of plant resources preservation and procreation. As a result there were obtained callus cultures of vegetative and generative organs of 11 wild orchid species. For the first time there was found the interrelation between the callusоgenesis from explants of orchid vegetative and generative organs and ratio of the phytohormonal complex components at the specific stages of the ontogenesis that must be taken into account during the development of methods of these species clonal micropropagation. The maximum frequency of callusоgenesis in specific cultivation conditions was shown to be characteristic of the orchid generative organs which have a high content of cytokinins, IAA and low level of ABA.
