Yeremenko N. (2019): Ruderal vegetation of the class Polygono-Poetea annuae in Kryvyi Rih (Ukraine) – Thaiszia – J. Bot. 29 (1): 001-021. –

Abstract: The present paper studies the ruderal vegetation of the class Polygono-Poetea annuae in Kryvyi Rih. We present the ruderal plant communities of short annual species on the open, moist to dry ecotopes. Urban landscapes remain unstudied phytosociologically despite the highly diverse habitat niches. We have carried out the comparisons of communities from other regions of Ukraine and adjacent territories. In total, two associations and two variants, belonging to alliance were identified and categorized as follows Polygono-Coronopodion (the communities with the dominance of Polygonum aviculare). The ordination analysis indicates ecological differentiation of syntaxa investigated in Kryvyi Rih. The most important of them are soil water regime (Hd), variability of damping (fH) and soil aeration (Ae).
Keywords: syntaxonomy, classification, trampled vegetation, ecological differentiation.

Kučera P. (2019): Two new wet woodlands with Norway spruce from the Western Carpatians. – Thaiszia – J. Bot. 29 (1): 023-049. –

Abstract: Two new associations of wet woodlands with Picea abies from the Western Carpathians are described. Stands of the first unit, Leucobryo glauci-Piceetum abietis, are located on dryer margins of mires, on plains where water from snow melting and rains remains considerable long above the soil surface. The most characteristic sign of the species-poor flora of this forest plant community is the dominance of moss Leucobryum glaucum accompanied by constant presence of Sphagnum spp. Two subassociations are distinguished in respect of the ecological differences. The second described plant community, association Stellario nemorum-Abietetum albae, occupies quite different habitat of spring areas and other more wet localities. Abies alba plays an important role in the canopy, field layer is characterised by constant presence of Stellaria nemorum, Equisetum sylvaticum, Oxalis acetosella, Senecio ovatus, Chaerophyllum hirsutum, Lysimachia nemorum and other species. Three subassociations and five variants are distinguished.
Keywords: Abies alba, ground-water, mire, Picea abies, phytocoenology, spring areas, syntaxonomy, Western Carpathians.

Dítě Z., Dítě D., Feráková V. (2019): Eleusine indica (L.) Gaertn., new species of the adventive flora of Slovakia. – Thaiszia – J. Bot. 29 (1): 077-084. –

Abstract: First two records of Eleusine indica in Slovakia are presented. This exotic grass species originating from the tropical Old World was found in the Podunajská nížina Lowland (Eupannonicum): in 2017 in Štúrovo and the next year in Bratislava, municipal part Karlova Ves. Both populations counted only three individuals grown in the pavement cracks. The habitat conditions of each locality in detail are characterized. Whereas Slovakia is among the last countries where E. indica was just discovered within Europe, we discuss the environmental conditions and the origin of the species in the backlight of earlier studies related to its occurrence in the surrounding countries.

Jimoh M. O., Afolayan A. J., Lewu F. B. (2019): Germination response of Amaranthus caudatus L. to soil types and environmental conditions. – Thaiszia – J. Bot. 29 (1): 085-100. –

Abstract: Little attention is being paid to Amaranthus caudatus in the Eastern Cape Province and other parts of South Africa as a vegetable that has huge potentials in bridging nutritional gap between the rich and the poor. This work investigated germination response of the plant to environmental conditions and variation in its germination characteristics at various depths in different soil types with the intent of complementing limited data available on the general agronomy of the species. At the end of the study, the highest germination was recorded at 25 °C and under continuous dark conditions, although the seeds germinated well under a wide range of temperatures and other photoperiods. The species germinated under all seeding depths considered, though late emergence was observed at depths below 2 cm. In addition, a significant (P < 0.05) interaction in pattern of germination was observed in three out of the five soil types tested, whereas the control (unfractionated) soil showed a highly significant (P < 0.01) interaction with the silt clay loam and loam soil. This overlapping interaction further confirmed that the plant has wide surviving capabilities in various soils and environmental conditions, hence, for optimum seedling emergence, it is recommended that A. caudatus be planted in a loamy soil maintained at 25 °C in a continuous dark environment.
Keywords: Alternating temperatures, Amaranthus caudatus, germination characteristics, photoperiods, sowing depth.

Amini E., Nasrollahi F., Sattarian A., Isazadeh-Araei M. & Habibi M. (2019): Systematic and molecular biological study of Sambucus L. (Caprifoliaceae) in Iran. – Thaiszia – J. Bot. 29 (2): 133-150. –

Abstract: Sambucus is a medicinal plant with approximately 25 accepted taxa in the world from which two are present in Iran, S. nigra and S. ebulus. In order to evaluate the affinities and relationships in Sambucus and resurrect subspecies or verities in these two species, the micro-morphological, anatomical and molecular properties of Sambucus species of Iran have been studied. Pollen and seed surfaces of two species were examined with scanning electron microscope. In micro-morphological studies, the pollen shape is prolate-spheroidal in S. nigra but subprolate in S. ebulus. The exine sculpture is microperforate in S. nigra and is reticulate-microechinate in S. ebulus. The surface of the seed in S. nigra is smooth, not elongated and no clear organizational pattern is discernable and the anticlinal walls are shallowly undulate. In S. ebulus, the seeds have a microperforate surface and the anticlinal walls are observed deeply undulate. Petiole anatomical studies show that vascular bundles and existence of druse crystals are diagnostic characters in studied species. Using nuclear (nrDNA ITS) marker, we reconstructed phylogenetic relationships within two species of Sambucus. The ITS dataset was analyzed by phylogenetic methods including Bayesian inference, maximum likelihood and maximum parsimony. In phylogenetic analyses, all members of this genus form a well-supported clade (PP = 1, ML/BS = 100/100). The Sambucus clade is composed of two clades. Clade I includes the populations of S. nigra and the clade II comprises the rest of the species of Sambucus (S. ebulus). NeighborNet diagram demonstrated separation of the studied populations. In general, molecular studies supported micro-morphological findings. Pollen, seed-coat characters and molecular phylogeny support the separation of S. nigra and S. ebulus. Keywords: Iran, micro-morphological, molecular, nrDNA ITS, pollen, Sambucus, seed.

Abstract: Adenostyles alliariae (Gouan) A. Kerner (Asteraceae) represents a single species of the genus Adenostyles in Slovakia. In the paper it is characterized from the point of view of chromosome number, genome size, breeding systems and distribution in Slovakia. Chromosome number 2n = 38 was confirmed in this study. Flow cytometric analyses resulted showed the genome size 18,19 pg for leaves and 19,4 pg for seeds. The flow cytometric seed screen method proved, on the basis of embryo to endosperm genome size ratio, that the species reproduces sexually. The occurrence of the species is bound to all higher mountain ranges of West Carpathians, above all to the Malá Fatra Mts., the Veľká Fatra Mts., the Nízke Tatry Mts. and Tatry Mts.
Keywords: nuclear DNA amount, chromosome number, occurence, mountain flora, Carpathians.

Kovalenko O. A. & Kalista, M. S. (2019): Germination bi­ology of Parthenocissus quinquefolia (L.) Planch. (Vi­taceae). – Thaiszia – J. Bot. 29 (2): 179-190. –

Abstract: We tested germination of seeds of Partheno-cissus quin­quefolia (L.) Planch. (Vitaceae) in laboratory in response to dif­ferent ecological factors: light intensity, temperature, humidity, acidity and salinity. Our results show that the most critical ecolog­ical factor is humidity. The highest rank of germination was 73 % in condition of sufficient moisture, 37 % in condition of excessive moisture and only 3 % in condition with insufficient moisture. Among variants with different reaction of medium the most suc­cessful germination was at pH 7 (73 %) and pH 9 (44 %). Anoth­er significant factor for seedlings germination of P. quinquefolia is lighting, since at full-dark, dark and semi-dark conditions the lev­el of germination was 0 %, 2 % and 24 % respectively. The per­centage of P. quinquefolia germination decreases with increasing salinity level. The most optimal germination regime was at +25 °C. Further study of P. quinquefolia biology will allow to clari­fy the difference in naturalization level between this species and closely related P. vitacea as well as to estimate the possibility of transformation of the introduced species into invasive.
Keywords: germination, ecological factors, Parthenocissus quinque­folia.

Goncharenko, I. & Kovalenko, O. (2019): Oak forest of the class Quercetea pubescentis in Central-Eastern Ukraine. – Thaiszia – J. Bot. 29 (2): 191-215. –

 Abstract: The article is devoted to the phytosociological study and vegetation classification of the dry-mesic oak forests in the central and eastern regions of Ukraine. We showed that oak for­ests of the Quercetea pubescentis class have specific northern features in the region and their syntaxonomic position at the level of alliances was not assigned. Syntaxa formed three dis­tinct geographical groups eastward from the Dnieper lowland to the Middle Russian Upland. Ordination, phytoindication, and comparative floristic analysis with other syntaxa from adjacent regions were performed. New associations (Digitali grandiflo­rae-Quercetum roboris ass. nova and Carici praecocis-Querce­tum roboris ass. nova) were reported. Two edaphic subtypes of dry-mesic oak forests (terrace and ravine oak forests) were distin­guished and their floristic features were discussed.
Keywords: forest-steppe zone, Quercetea pubescentis, syntaxono­my, thermophilous oak forests, Ukraine.

Naydenova, G. & Vasileva, V. (2019): The potential breeding value of snow clover (Trifolium pratense ssp. nivale (W.D.J. Koch) Arcang.) and red clover (Trifolium pratense ssp. sativum) hybrids. – Thaiszia – J. Bot. 29 (2): 217-224. –

Abstract: Eight red clover subspecies are registered in Europe but it can be considered that the high genetic diversity and local genetic adaptation existing at a subspecies level is unused. The experiment aimed at studying agronomical traits of the hybrids obtained from crosses of wild subspecies of Trifolium pratense – snow clover (Trifolium pratense ssp. nivale (W.D.J. Koch) Arcang.) and cultivated red clover (Trifolium pratense ssp. sativum). Under field conditions, two snow clover half-sib families – F1 generation of crossbreeding were selected and compared to the paternal variety Nika 11 for three years. According to results, the size, habit of growth as well as dry matter productivity at spring growth of the F1 hybrids were similar to the cultivated red clover. In summer regrowth, they were less productive. In terms of a type and rate of development the hybrids were similar to snow clover. From morphological point of view, the families proved of interest with its abundant leafiness, which renders them suitable for breeding in pasture direction. The hybrids are characterized by an icreased number of seeds per inflorescence and seed yield. The open-pollinated seeds of families were used for the formation of a population that represented the F2 generation progenies. The phenotypic variation in the first vegetation of F2 generation was high for plant flower colour, growth habit, and degree of pubescence. It can be considered that this population contains a high genetic variation and is suitable for development of complex hybrid breeding populations.
Keywords: intersubspecific hybrids, morphological traits, red clover, productivity, snow clover.
