The effect of foliar feeding with four biostimulants with active substances (Ecklonia maxima algae extract, titanium, humic substances, plant hormones: auxin and cytokinin) on the chlorophyll content and plant height of three Solanum tuberosum cultivars was investigated. A field experiment was carried out in 2015–2017 in eastern Poland in three growing seasons using the split-plot method. The cultivated varieties significantly differentiated the chlorophyll content (SPAD index) and plant height. The research showed the influence of varieties and many years of research on the height of potato plants. The biostimulants increased the value of the SPAD coefficient and the height of the potato plants.

Palynological materials for the present study are well preserved apiculate miospores collected from palynoassemblage MS-6 of Mstikhino quarry, Kaluga Region. The unique palynoassemblage MS-6 has been extensively studied by the authors in recent years (Mamontov 2012, Mamontov & Orlova 2014). The unusual attribute of the assemblage is a great variety of the miospores with transition apiculate sculpture (grain-coni-papillae). However, it remained unclear whether the different ornamentation types had similar ranges of variation within both the sculptural elements and arrangement of the ornaments. The general purpose of the research is comparison of similar sculptural patterns from triangular apiculate miospores based on the range of morphological variation. Preliminary results of sculpture analysis of some apiculate miospores from the locality have been obtained. For the present study thirty specimens of each species Granulatisporites granulatus Ibrahim, Iugisporis subintortus (Kedo) Mamontov comb. nov., Lophotriletes parviverrucosus (Waltz) Kedo were accidentally sampled from the assemblage MS-6. All specimens were examined by the methods of transmitted light and scanning electron microscopy. Additionally we applied the model of sculptural analysis introduced and modified by Vezey et al. (1992). Measurements of sculptural features were carried out by the image-analyzing software ImageJ. Statistical data were summarized in the MS Excel. Thus several sculpture variables have been measured: - average Wadell’s diameter (it is diameter of circle having a same area as a base of the sculpture elements (grain, coni or papillae)); - average height of the elements; - average distance between the edges of adjacent elements; - average polar diameter of spore; - average length of the trilete rays; - spore outline; - quantity of elements on the visible spore hemisphere; - quantity of elements are located along the spore equator. Fifty measurements of the each variable were produced. Range of variation for the features was evaluated by coefficient of variation (CV). As a result of the analysis the three species are defined by continuous variation of the polar outline between triangular concave to triangular with slightly convex sides. Similarities within shape and size of the elements were indicated. Grains, coni and papillae are characterized by similar continuous variation of apices with blunt, pointed and rounded shape. Some of the elements are supplied by bifurcating tops while the other ones are fused by the bases. Amount of the elements is differed within each species. Ornamentation of the Granulatisporites granulatus is restricted by about 290 elements of the proximal hemisphere. The same feature of the Iugisporis subintortus is defined by about 212 coni-like elements. In contrast the Lophotriletes parviverrucosus are attributed by about 170 sculptural unites. All specimens of Iugisporis are characterized by medium coefficient of variation 26% for diameter of the base of the coni (Wadell’s diameter), but the CV of height of the elements is about 35%. Variation of the distance between the coni is extremely high 60%. For the Lophotriletes specimens CV of the Wadell’s diameter is increased up to 30% and variation of the height of papillae became more stronger – 44%. However, there are no differences in CV of the distance between the papillae in comparison to the Iugisporis. Coefficient of variation of Wadell’s diameter for specimens of Granulatisporites is indicated by level 25%. Variability of grain height is about to 30%. However, variance of distance between the adjacent grains is decreased up to 40% in contrast to other species. Variation of the polar diameter and length of rays from the all specimens are inconspicuous changed up to 12%. Additionally specimens of the all species are marked by correlation between amount of elements along the spore equator and concavity of the interradial sides of spore outline. Quantity of the equatorial elements was salutatory increased while the interradial sides became more concave. However it would generally depend on the average polar diameter of the spores. Significantly, size of the sculptural elements unevenly increased ongoing from polar area to equatorial margin of the spores. In additional, continuous variation between granulate, coni and papillae ornamentations have been observed within the studied specimens. Accordingly, all morphological features of the genera Granulatisporites , Iugisporis , Lophotriletes were subdivided into three categories: 1) common characteristics which are more stable: polar diameter, length of rays, spore outline; 2) variable characteristics which are defined by high coefficient of variation: quantity of elements, height of the elements, distance between the edges of adjacent elements, Wadell’s diameter; 3) variable qualitative characteristics: shape, type and distribution of sculptural unites. The results lead us to believe that such qualitative characters as type, shape and arrangement of sculpture elements are strongly connected with measured CV of characteristics from b) category. In accordance to morphon concept introduced by van der Zwan (1979) the group of miospore species is united in morphon by similar continuous variation of morphological features. Therefore, such morphologically similar species have the same range of CV of the coincident sculpture features. However it should be noted that this conclusion are restricted by common occurrence of transitional sculpture variations of the apiculate spores. Also it is possible that different value CV from different variables were caused by the different role of the sculptural feature in natural selection.

As a response to a preliminary study (Leung 2010) of five HK learners of English which found that those who had grown up hearing Filipino-accented English showed no trace of this accent in their production, this study probes further to look for more subtle signs of exposure to Filipino English. Data were collected from 10 speakers aged 2½ to 25 who were divided into three groups. Both Groups A and B were initially exposed to Filipino-accented English input at home, and Group A continued to receive such input. Group C had not received any Filipino-accented English input at home. Findings from two perception tasks targeting English words with /p/, /t/, /k/, /f/, and /v/ onsets spoken in a Filipino accent showed that speakers with exposure to Filipino-accented English could better perceive these words than those who had none. A decline from Group A to C was found in their ability to recognise target phonemes, indicating that quantity and/or recency of input play a role. These results raise the issue of incipient/passive-bi¬lin¬gual¬ism (Diebold 1964; Romaine 1995) and call for more detailed study of attitude, accommodation and identity with respect to the acquisition of a given second language variety.

We show that any finitely generated variety V of double Heyting algebras is finitely determined, meaning that for some finite cardinal n(V), any class $\Cal S$ ⊆ V consisting of algebras with pairwise isomorphic endomorphism monoids has fewer than n(V) pairwise non-isomorphic members. This result complements the earlier established fact of categorical universality of the variety of all double Heyting algebras, and contrasts with categorical results concerning finitely generated varieties of distributive double p-algebras.

The aim of this paper was to reduce confusion around the concepts of dialect and language. Although linguists often use separate terms, there are no linguistic criteria to make a distinction between the two. It is also difficult to delineate the boundaries of specific languages or dialects. Classification attempts may lead to developing linguistic hierarchy, therefore it is necessary to know that any distinction is artificial and arbitrary. In view of no clear definitions of dialect and language, the use of a neutral term “variety” is preferred. Human perception of linguistic reality – diverse varieties and their mutual relations – is the outcome of subjective, political decisions and organised social activity. Distinction between a dialect and a language is volatile – e.g. colloquial Latin had evolved into dialects that, over time, transformed into the Romance languages. The evolution of the Castilian language on the Iberian Peninsula shows how social and political factors, rather than linguistic ones, influence the actual status of a linguistic variety.

Many languages belong to pluricentric languages. Starting from the monocentric approach the development of the pluricentric term is explained. The definition includes the national variety of a language as well as dominant and non-dominant varieties. The dominant national variety often “exports” language expressions to the non-dominant one. This is explained within the pluricentric languages of German. The acceptance of the pluricentric approach, which is already wide-spread in German studies nowadays, should nevertheless be followed by certain consequences in translation studies and in teaching German within the German speaking countries as well as in teaching German as a Foreign Language. With some desiderata for the future the article is closed.

In years 1999-2000 an experiment was carried out in the Brody Experimental Station in which the author assessed the usefulness of 20 cultivars of Festuca rubra and 4 cultivars of Festuca ovina for extensive lawn utilisation in the year of sowing and in the first year of utilisation. The experiments comprised the following determinations: the degree of plant tillering (9° scale), number of leaves per plant, number of tillers developed by a plant, sodding (using Weber’s method), sward height (using a herbometer), sward yield (from the area of 0.5 m2) and yield of the root bulk (from a cylinder of 6 cm diameter and the depth of 8 cm). The performed studies were carried out on 1 m2 plots in three replications. In conditions of extensive lawn utilisation, out of 20 cultivars of Festuca rubra, Nimba, Barcrown and Aniset deserve positive marks. In comparison with Leo cultivar, the above cultivars were characterised by better sodding, shorter sward, similar sward yield and distinctly greater weight of roots. Napoli and Smirna received the worst marks for the examined traits. Out of the 4 examined cultivars of Festuca ovina, Mimi proved the best one from the point of view of its sodding traits and root yield although it developed higher plants. Noni also turned out to be a very interesting breeding creation characterised by a very slow regrowth and good sodding. Sodding, sward height and plant over ground and root yields turned out to be good criteria for the assessment of grass cultivar suitability for extensive lawn utilisation.

In the development of languages (including varieties) nationalities or countries play an important role. That is how pluricentric languages have developed. In the field of German as a pluricentric language many articles have already been published in scientific magazines. In spite of that the pluricentricity of languages is hardly acknowledged – the effects can be seen in dictionaries, in programs of teaching at universities (literature, linguistics as well as translation studies), but above all in text books for students, where elements of pluricentricity are usually absent. That is why some desiderata for the future teaching German as a Foreign Language ought to be expressed.

Effective competition for access to social resources is dependent on skills defined also as competences for action, cooperation and counteraction. Therefore, the objective of the study was to formulate a consistent set of criteria by means of which it would be possible to ensure objective identification of an individual's skills to take action in competitive conditions, with particular attention to sport game and fight. It was assumed as the basis of the paradigm that the skill of sport game and fight is the conscious or intuitive application of solutions surprising the competitor by their uniqueness, choices or speed of action. The following criteria were distinguished among the criteria proposed for identifying competitive skills: surprise by creativity of action shown by precision, flexibility and uniqueness of performance, surprise by choice indicated by the dynamics of the repertoire of actions, and surprise by speed of action resulting from increasing velocity or making use of the variability of rhythm, speed and direction of action. The concept presented appears to be a consistent paradigm of objectivized identification of competitive skills. On the basis of this identification, it is possible to formulate practical directives which allow for the improvement of processes: educating, coaching, or managing the development of competences with respect to effective competition for access to social resources, including sports resources.

For the successful development of the agricultural sector, one of the main tasks during the cultivation of agricultural crops is the rational use of land resources and obtaining the highest possible quality of products with low labor costs. The practical value of the scientific article lies in the improvement of the elements of the technology of growing soybean varieties that differ in groups of maturity. The development of ecological and economic technological parameters made it possible to ensure the seed yield, depending on the maturity groups of high-tech varieties, up to 2.91 t/ha with high production profitability. The object of researchinvolved the processes of growth, development and formation of the soybean seed crop, as well as its quality depending on the developed technological parameters. The subject of research comprised soybean varieties, pre-sowing treatment of seeds with a bacterial preparation and a growth regulator. It was determined that soybean belongs to the high-protein strategic agricultural crop of Ukraine and the world. Providing the population with protein food is a global problem, because the increase in population significantly exceeds the production of protein products. Soy, which is characterized by a rare chemical composition, plays an important role in solving this problem – its seeds contain 38–42% protein, 18–32% fat, 25–30% carbohydrates, enzymes, vitamins, minerals, many essential amino acids with a significant degree of solubility and nutrition. This feature has a positive effect on the environment and allows obtaining ecologically clean products. The cultivation of soybeans is of great agrotechnical importance, as it is a good precursor for the cultivation of the vast majority of agricultural crops. However, the determining factor for obtaining a high yield of soybeans is the variety. On the basis of the research results, their economic analysis and with the aim of growing high soybean yields at the level of 2.91 t/ha, the agro-forming of the right-bank forest-steppe of Ukraine recommended sowing the intensive soybean variety Sandra – carrying out pre-sowing treatment of soybean seeds with the bacterial preparation Rizotorphin in combination with the growth regulator Vermyst. Therefore, the scientific work is devoted to researching the yield and nutritional value of soybeans of different varieties depending on the inoculation of seeds with bacterial preparations and treatment with growth regulators, which is relevant as well as of scientific and practical interest in the field of ecologically oriented growing technologies.

The field experiment was conducted in the years of 2012–2014 in the Agricultural Experimental Station Zawady belonging to the University of Natural Sciences and Humanities in Siedlce. The two factor experiment was set up in the split-plot system in triplicate. The investigated factors were: I – three varieties of edible potato: Bartek, Gawin and Honorata. II – five ways of care: 1. Harrier herbicide 295 ZC – 2.0 dm3·ha-1; 2. Harrier herbicide 295 ZC – 2.0 dm3·ha-1 with the biostimulator Kelpak SL – 4.0 dm3·ha-1; 3. Sencor herbicide 70 WG – 1.0 kg·ha-1; 4. Sencor herbicide 70 WG – 1.0 kg·ha-1 with the biostimulator Asahi SL – 1.5 dm3·ha-1; 5. The control object – mechanical care. The content of zinc and copper and their collection with the yield of tubers significantly depended on the ways of care, genetic factor and climatic conditions in the years of the study. In the objects (2, 4) where herbicides were used with biostimulators, a greater concentration of zinc was obtained in relation to the control object and the remaining (3, 5) in which only herbicides were used. The applied care methods did not affect the content of copper in the analysed tubers. The greatest collection of zinc an copper with the yield of tubers was obtained in the objects: where the mixture of the Sencor herbicide 70 WG – 1.0 kg·ha-1 was used with the biostimulator Asahi SL – 1.5 dm3-1 and herbicide Sencor 70 WG in a dose of – 1.0 kg ·ha-1.

The determination of the turf grasses seeded in Grass-Paver grate growth and development was the aim of the study. The grate construction is based on the rule of honeycomb. The three grass mixtures (1 Dutch and 2 Polish) and three substratums different in percentage of sand (90, 60, and 40) were analysed in this study. The study has proved that construction margins have not deleriorated the conditions of growth and the development of grasses. The grasses on the entire surface emerged, grew and rooted well. After 4 weeks they covered 80% of the area and after 6 weeks the concise caipet with unseen construction elements was obtained. The kind o f applied mixture than substratum had influenced on the speed o f sodding in bigger grade. Polish mixture with sinaller share of perennial ryegrass (M3) characterised slower turfing what may get worse visual effect in first 6 weeks after seeding. In further period of vegetation all established turfings has presented very well. Underground biomass am ounted in general biomass in seeding year front 59% to 80% and in the following 85-92%. On substratum with highest share of sand smaller share of roots occurred. After applying mixtures with similar species composition but different varieties origin the significant differences in gratitude of biomes were stated. In foreign mixture in the first year of study both roots mass and above ground mass were significantly bigger than in second year of study. In different way reacted on kind of substratum, especially in second year of the study. The root mass has increased in Polish varieties and decreased in foreign ones with decreasing of sand share in substratum.

As the impact of global climate change increases, the interaction of biotic and abiotic stresses increasingly threatens current agricultural practices. The most effective solution to the problem of climate change and a decrease in the amount of atmospheric precipitation is planting extremely drought-resistant and high-yielding crops. Sorghum can grow in harsh conditions such as salinity, drought and limited nutrients, also it is an important part of the diet in many countries. Sorghum can be introduced in many zones of Kazakhstan. Plant height and yield of green plant biomass of 16 sorghum samples in arid conditions were determined based on a set of agrobiological characteristics for field screening. The height of the studied samples of grain sorghum was 0.47 ±0.03 m, and the height of sweet sorghum was much longer, reaching up to 2.88 ±0.12 m. Also, there was a strong difference in green biomass in cultivated areas under different soil and climatic conditions, the green biomass of sweet sorghum was 3.0 Mg∙ha-1, and in grain sorghum, it reached up to 57.4 Mg∙ha-1. Based on the data of the field assessment for various soil and climatic conditions, the following samples were identified for introduction into production: samples of sweet sorghum for irrigated and rainfed lands of the Almaty Region and in the conditions of non-irrigation agriculture of the Aktobe Region - a promising line ICSV 93046. For non-irrigation agriculture of the Akmola Region, genotypes of sweet and grain sorghum are ‘Chaika’, ‘Kinelskoe 4’ and ‘Volzhskoe 44’.

Spring wheat is the main export crop in Kazakhstan. The main share of the grain sold on the world market is the grain of spring wheat grown in Northern Kazakhstan, where the acreage used for this crop reaches 85%, which is about 10 mln ha. Moisture deficiency is the main limiting factor in increasing the yield of spring wheat; in this region, the average annual precipitation is 320–350 mm. Droughts of varying intensity have periodically occurred 2–3 times within the previous five years. Therefore, the yield variability is high and reaches 30% or more. Another reason for the low yield is the occurrence of wheat diseases. Brown rust and Septoria blight are the most common diseases in the region. Upon the joint manifestation of these diseases, the loss of grain yield may reach 30–40%. The research was aimed at creating a drought-resistant, productive, high-quality variety of spring wheat adapted to changes in the environmental conditions. The method of studying has been generally adopted in breeding and genetic studies. In the competitive grade testing, 40 promising lines of spring soft wheat were studied. Line 371/06 had an average yield of 2.54 t/ha, which was higher by 0.48 t/ha than in the standard, and ripened at this level. Over the three years of study, this line has significantly exceeded the Astana variety in terms of the yield. Line 371/06, which has Lr37/Sr38 genes in its genotype, is characterized by group resistance to brown and stem rust. The content of protein in this line amounted on average to 15.22%, which was by 1.38% higher than in the standard Astana variety. By the gluten content, the excess over the standard reached 2.8%. Over the three years of studying the 40 spring wheat lines, line 371/06 has been chosen, which is high-yielding, resistant to droughts, leaf and stem rust, and is of high grain quality. In 2018, line 371/06 was sent for state grade testing under the name of Taymas.
