Boiko M.F., 2010: The bryophytes with uncertain substrate ecology are common in the steppe zone of Ukraine. Chornomors’k. bot. z, Vol. 6, № 4: 417-427. ISSN 1990-553X

 

The results of the 20-years investigation of the bryophytes with uncertain substrate ecology in the steppe zone of Ukraine are summarized. Based on the response to substrate chemistry, studied bryophytes are divided into 7 ecotype classes: calciphilous, acidophilous, calcifugous, siliciphilous, halophilous, nitrophilous and indifferent. The bryophytes with uncertain substrate ecology (we call them "incertophytes" from the Latin "incertus" - not clear, uncertain) are abundant in the steppe zone of Ukraine: 171 species = 54,6 % of the species composition. Incertophytes are absent from the substrates with clear tendences in chemistry (e.g. strongly calcareous or strongly acidic). Genera, which include lots of incertophytes, are: Sciurohypnum – 100,0%, Amblystegium - 80.0 %, Orthotrichum – 78,57 %, Bryum – 77,7 % and Brachythecium – 75,0%. All of the leading families of bryophytes in the steppe zone contain number of incertophytes: Orthotrichaceae – 78,5 %, Bryaceae and Brachytheciaceae - both 75.0 %, Ditrichaceae – 71,42 %, Amblystegiaceae - 647 %, Hypnaceae – 64,28 %, Funariaceae – 62,5 %.

Features of the production process and growth of Achillea millefolium (Asteraceae) on flood plain meadows of the river Psel

Abstract

Korovyakova T.O., 2010: Features of the production process and growth of Achillea millefolium (Asteraceae) on flood plain meadows of the river Psel. Chornomors’k. bot. z., Vol. 6, № 4: 439-448. ISSN 1990-553X

 

Features of production  process and growth of Achillea millefolium have been studied on flood plain meadows of the river Psell, which are used as pastures and for haymaking. Dynamics in the basic indicators of growth is described. Vitality structure in populations of Achillea millefolium is defined on basis of pascual  and fenisicial  gradients.

Pomological and biochemical  features in ancestral forms and hybrids F1 and F2 Prunus brigantina Vill. × Prunus cerasifera Ehrh.

Abstract

Gorina V.M., Richter A.A., 2010: Pomological and biochemical  features in ancestral forms and hybrids F1 and F2 Prunus brigantina Vill. × Prunus cerasifera EhrhChornomors’k. bot. z., vol. 6, N 4: 449-461. ISSN 1990-553X

 

The results of  hybridization Prunus brigantiaca  x Prunus cerasifera  Ehrh. are  elucidated. In the first generation hybrids  show much later flowering period  and ripening of fruits in comparison with other cultivars. In the second generation hybrids have also higher content of dry substances, pectines and anthocyanes in its fruits.

Changes in chemical composition of fruits and leaves in Persica mira (Koehne) Kov et Kostina  within vegetation period

Abstract

Korniliyev G.V., Komar-Tyomnaya L.D., 2010: Changes in chemical composition of fruits and leaves in Persica mira (Koehne) Kov et Kostina  within vegetation period. Chornomors’k. bot. z., Vol. 6, № 4: 462-467. ISSN 1990-553X

 

Chemical compositions of fruit and leaves in Persica mira (Koehne) Kov. et Kostina during the vegetation season is studied. We identified that dynamics in accumulation of pectin and phenolic substances is similar  to P. vulgaris Mill., while dynamics in accumulation of the ascorbic acid and organic (titric) acids differs from P. vulgaris. In P. mira,catechins and leuсoanthocyanidines are strongly accumulated in fruits; ascorbic acid, carotenoides, protopectins, flavonols are present in leaves.

Abstract

Bagrikova N.A., 2010: Anthropotolerance of plant communities and strategy of weeds in agrocenoses of the Crimea. Chornomors’k. bot. z., Vol. 6, № 4: 468-474. ISSN 1990-553X

 

The estimation of stability of plant communities and ecological strategy of species in the conditions of the anthropogenic transformation of the environment in different agrocenoses of the Crimea is given. In segetal communities, euhemeroby (from 65 % to 98 %) and CR-strategy (43-61 %) predominate. In perrenial agroconoses, the increase of oligo- and mesohemeroby (up to 27 %), species with C-strategy (up to 25 %) and CSR-strategy (up to 27 %) has been observed. The greatest indexes of hemeroby (from -80 up to -90) are typical for cereal plantations and crop cultures.

Actual state of rare plant populations in the town of Vyshgorod and its surroundings

Abstract

Parnikoza I. YU., Chernyshenko M. S., 2010: Actual state of rare plant populations in the town of Vyshgorod and its surroundings. Chornomors’k. bot. z., Vol. 6, № 4: 491-505. ISSN 1990-553X

 

During the last nine years of research and monitoring of rare plants populations in the vicinity of Vyshgorod, the town north of Kyiv (Ukraine), it has been shown that the population of Equisetum telmateia is stable, though it suffers from recreation activities (trampling, etc). Epipactis palustris populations mostly reflect changes of surrounding vegetation. Two orchids, Liparis loeselіi and Listera ovata, are persistently rare, but with a good age structure and with  vegetative reproduction. Dactylorhiza incarnatа is more abundant; its age structure is good in all studied fragments of populations. These populations are especially important for saving the gene pool of the species in the territory affected by the sucking vortex of Kyiv fervent development. The localities of Orchis coriophora and Orchis palustris are very valuable. The abundance of Salvinia natans strongly fluctuates. Vyshgorod and its vicinity is an inestimable refuge for number of regionally rare species, which should be studied more profoundly. Our data represent  an argument for (1) enlargement of the natural monument "Velykyj Hwosch", (2) creation of new natural reserves "Silskyj Yar" and "Gorianskyj Yar" in Vyshgorod gullies and (3) creation of the botanical natural monument “Orchidejna girka” on the bank of Dnieper.

First record of fertile Caloplaca arcisproxima and designation of its epitype

Abstract

Vondrák J., Vondráková O., Khodosovtsev A., 2010: First record of fertile Caloplaca arcisproxima and designation of its epitype. Chornomors`k. Bot. z.,Vol. 6, N 4: 506-507. ISSN 1990-553X

 

Caloplaca arcisproxima (Teloschistaceae, lichenized fungi)was described from sterile specimens. Subsequently, we collected fertile thalli of the species in the Crimean Peninsula (Ukraine) and we provide characters of apothecia as its additional identification. Although the species is usually distinguishable by the shape of its sorediate squamules, the fertile specimen possesses characters of apothecia and we designate it as the epitype of C. arcisproxima. Identification of the epitype was supported by its ITS nrDNA sequence.

Duration of transition into the monad stage as a useful criterium for identification of species within Chlamydomonas (Chlorophyta)

Abstract

Pavlovska M.N., Kostikov I.Yu., 2010: Duration of transition into the monad stage as a useful criterium for identification of species within Chlamydomonas (Chlorophyta). Chornomors’k. bot. z., Vol. 6, № 4: 508-512. ISSN 1990-553X

 

Methods for evaluation of the duration of the transition from vegetative cells to the monade state are described. Duration of the transition state, iniciated by the transfer of cultures from solid to liquid media, corresponds with molecular clades. This was observed on the sample of 12 species presented by 12 authentic strains which belong to 4 different larger clades. Duration of the transition depends on: (1) presence of the flagella in immobile cells, (2) capability to form flagella de novo, (3) presence, solubility and width of mucilage sheaths on surface of vegetative cells in their immobile state.
