Abstract The activities of the Dendrological Society in Průhonice have significantly influenced the introduction of woody plants into the territory of today‘s Czech Republic. This is evidenced by a significant handwritten document – The Register of plants of the Dendrological Society that records the introduction period between 1909 and 1924 (10,050 items). The collections of seeds (plants) from E. Taquet, H. Shirasawa and J. Unger played an important role in the introduction of woody plants to Průhonice with over 157 taxa of woody plants from their collections being introduced between 1909 and 1912. From the total number of 157 taxa, 80 items were introduced to Průhonice before anywhere in the Czech lands. This work aims to provide a new knowledge acquired from studying the above-mentioned document, about the time and place of these introductions. A significant part of this work is a detailed overview of the particular woody species introduced to Průhonice.

Abstract The paper represents a waste composition study that was conducted at the Mladosť dormitory of the Slovak University of Agriculture (SUA) in Nitra. The aim of the study was to determine the amount and composition of waste generated in the dormitory and to provide recommendations for enhancing the recycling rates and to improve the overall sustainability of waste management in the dormitory. The analysed solid waste was separated into organics, papers, plastics, glass, metals, cardboard beverage packaging (tetrapak), electronic waste (e-waste), and others. The estimated annual average quantity of waste generated per student of the dormitory is 38 kg. The composition of generated solid waste is as follows: paper (6%), glass (26%), plastic (9%), metal (4%), organic (28%), tetrapak (2%), e-waste (1%) and other waste (24%). Potential recycling rate of generated waste is 76%. Composting is the most sustainable method to convert organic waste into valuable compounds and to reduce the waste disposed into landfills.

Abstract In the years 2013–2014 we evaluated changes in concentrations of chlorides and sulphates in waters of the National Nature Reserve Čičov oxbow depending on the time and place of sampling. Collections of samples were realized regularly at monthly intervals, always in the half of a month. Sampling sites were determined in order to assess the impact of natural and anthropogenic source of surface water quality. In order to evaluate the quality of surface water in the sampling sites by individual indicators, we used the values of the 90th percentile (P90), which was calculated from the measured values and then compared with their matching set of limit values referred to the Regulation of the Government of the Slovak Republic No. 269/2010 Coll. According to that Regulation, the recommended value for chlorides is 200 mg dm;; and for sulphates 250 mg dm−3. Based on the calculated values of 90th percentile (P90) of these indicators, we found out that the calculated characteristic values are lower.

Abstract In this study, the number of stomata per unit area was determined in the perennial energy grass of two genotypes Miscanthus × giganteus (Greef et Deuter) and M. sinensis ‘Tatai’ on arable land in the South-western Slovakia. The dynamics of stomatal density per mm2 was determined by non-destructive method in three randomly selected clumps. The number of stomata per mm2 of area varied from 125 ±23 to 327 ±47, stomatal length ranged from 33.9 ±4.7 μm to 35.3 ±3.4 μm, and stomatal width ranged from 17.5 ±2.3 μm to 18.8 ±2.8 μm in the two genotypes. We confirmed ontogenetic heterogeneity of leaf area size and stomatal size parameters.

Abstract Soil water storage and its spatial pattern is one of the biggest tasks in agricultural field of study. Correct spatial interpretation and quantification of soil water storage are considered crucial for correct hydrological zonation of agricultural lands. This paper is focused on determination of amount of plants available soil water in the Nitra River Catchment in 2013. Available soil water storage was computed for each quarter of the year (I.–IV.; V.–VIII.; IX.–XII.) for 60 cm soil horizon. Amount of available water was determined as a difference between actual soil moisture and hydrolimits of water availability. Actual soil moisture was interpolated from point’s values from net of hydrological stations in the Nitra River Catchment. Limited water availability was calculated by retention curves from soil samples taken in the Catchment. Available soil water storage was the highest in the first quarter (36.74 mm). In the second quarter, it decreased to 26.93 mm and in the third quarter it was only 4.11 mm. In the fourth quarter, it increased to 30.13 mm.

Abstract Dynamics of onion seeds germination with different germinability and magnetic field influence with variable intensity on onion germinative activity was determined in trials. Amika F1 hybrid marked low germinative activity. On 21th day after trial foundation it reached germinability of 34–46%. Halftime of this germination was reached on fourth to fifth day after trial foundation. Exhibition variety had convenient germination activity, 70–91%. Halftime of its germinability was reached on sixth to eighth day after trial foundation. On the base of submitted results there can be said that the seed with low germinative activity has faster initial start of germination. The seed with suitable germinative activity has more regular course of germinability from the beginning till the end of germination. Seeds of varieties Amika F1 and Exhibition achieved significantly lower germination in the radiation intensity of 20 mT compared to other variants with the radiation intensity of 40 mT, 55 mT and the control one. Between the variants of 40 mT, 55 mT and the control one the differences were not significant.

Abstract One-year field experiment with spring barley (Hordeum vulgare L.) was carried out to evaluate the effect of biochar amendment on the pH of Orthic Luvisol at the research site located in western Slovakia (lat. 48° 19′ 00″; lon. 18° 09′ 00″). Biochar with higher pH (8.8) was applied to slightly acidic soils with the initial pH at 5.6. The field experiment consisted of control, 10 and 20 t ha−1 (B0, B10, B20) of biochar application to soils combined with three levels of nitrogen fertilization (0, 40 and 80 kg N ha−1) (N0, N40, N80). The soil pH (KCl) at depth 0–10 cm was measured once a month (March – October, 2014). Application of both biochar rates (10 and 20 t ha−1) increased pH (in all months) with the magnitude of 0.13–1.09 units in all three fertilization levels (0, 40 and 80 kg N ha−1) compared to the control one. However, the significant increase (p <0.05) was found only in the treatment B10N0 (3 of 8 measurement events) and B20N0 (6 of 8 measurements) when no nitrogen was applied and in the treatment B20N80 (5 of 8 measurements) when 80 kg of nitrogen was applied. According to this, the biochar incorporation to soil can be suggested as a possible way to ameliorate soils and may be effective in increasing soil pH.
摘要以春大麦(Hordeum vulgare L.)为研究对象，在斯洛伐克西部进行了为期一年的田间试验，研究了生物炭改性对草甘醇pH值的影响。48°19 ' 00″;朗。18°09 ' 00″)。将pH值较高(8.8)的生物炭施用于初始pH值为5.6的微酸性土壤。田间试验包括对照、10和20 t ha - 1 (B0、B10、B20)生物炭与3个氮肥水平(0、40和80 kg N ha - 1) (N0、N40、N80)相结合。每个月(2014年3 - 10月)测量1次深度为0 ~ 10 cm的土壤pH (KCl)。与对照相比，施用生物炭(10和20 t hm - 1)在所有三个施肥水平(0、40和80 kg N hm - 1)下均使pH值(在所有月份)增加了0.13-1.09个单位。然而，只有未施氮处理B10N0(8次测量事件中的3次)和B20N0(8次测量事件中的6次)和施氮处理B20N80(8次测量事件中的5次)显著增加(p <0.05)。因此，在土壤中掺入生物炭可能是一种改良土壤的方法，并可能有效提高土壤pH值。

Abstract The aim of this work was to determine and compare the occurrence of epigeic groups in two methods of farming, ecological one and integrated one. The research was conducte in the locality Nitra – Dolná Malanta in the years 2013 and 2014. The monitoring locality is situated in the south-western part of Slovakia, in altitude 175–180 m on highly productive soils. For the collection of biological material, the earth traps method was applied, used during the vegetation period (from April to October), within both farming systems, at Hordeum sativum, Triticum aestivum and Vicia faba undersowing with Medicago sativa. In canopy of these crops, two soil traps were installed, renewed in monthly intervals. The total of 7,722 exemplars of epigeic groups was obtained, of which 4,355 exemplars were in ecological farming and 3,367 exemplars in integrated farming system. In both treatments, 19 epigeic groups were determined, with dominant abundance of Coleoptera, Collembola, Acarina, Araneae. Also other groups such as Diplopoda, Heteroptera, Chilopoda etc. were observed in lower occurrence. Based on the evaluation of influence of the crop in terms of the occurrence of epigeic groups, the most suitable conditions created Vicia faba with undersowing Medicago sativa (integrated farming) and Triticum aestivum (ecological farming). On the basis of calculated indexes, both farming systems can be evaluated as homeostatically balanced, providing present epigeic groups with topical and trophic conditions.

Abstract In the study regarding with tomatoes, the impact of extremely low frequency electromagnetic fields on seed germination of tomato (Solanum lycopersicum L.) after treatment before sowing, as well as the growth following electromagnetic stimulation of young plants at a time before planting in the field, and fruittraits was investigated. In the experiments conducted in two consecutive years (2012 and 2013), we followed the time of seed germination of tomato variety “Pavlina”, plant growth and the fruitsize. Magnetization of seeds and young plants was carried out in laboratory conditions, and plant growth and fruits were followed in field conditions where plants were grown on experimental plots (25.0 m2). The plants were grown in accordance with the standards of agricultural practice for tomato. At the generative phase, fruits were collected at regular intervals, and their number and weight were evaluated. Low frequency electromagnetic fields acting at the three inductance levels (20, 40 and 60 mT) and exposure of 20 minutes a day with frequency of 50 Hz, significantly influenced the germination, plant growth and fruitsize of the studied tomato variety.

Abstract The results of imperfect knowledge of the natural environment’s basic laws show that the negative effects of our actions are manifested in most cases only belatedly, in forms such as: the loss of arable land, the extinction of rare species of plants and animals, the depletion of the ozone layer, the climate change, the deterioration of air quality, the acid rain, the worsening quality of surface and ground water, the surface loss of rainforests and many other negative aspects of our thoughtless actions. For the measurement of sulphur concentration, we chose locality surrounding the power plant Vojany, where we identified two locations for mounting our stands. The first place was the village Tušice, and the second one the area of AMS Leles. This is where we planted in alkaline strips in stands used for this purpose and by the sorption – cumulative method we evaluated concentrations of sulphur amount collected on the strips. In the period 2012–2014, we conducted experiments in regular 30-day intervals; we performed 104 analyses of filter plates using the sorption-cumulative method. The current position of some habitats infestation causes damage to various parts of environment. Therefore, we consider it relevant to continue in monitoring this affliction and quantifying the extent of its negative effects. The proposed procedure with the possibility of a retrospective determination of concentrations of SO2 using mathematical modelling can also be used for the determination of old burdens.

Pokrývková, Emília Micáková","doi":"10.1515/ahr-2015-0006","DOIUrl":"https://doi.org/10.1515/ahr-2015-0006","url":null,"abstract":"Abstract The results of imperfect knowledge of the natural environment’s basic laws show that the negative effects of our actions are manifested in most cases only belatedly, in forms such as: the loss of arable land, the extinction of rare species of plants and animals, the depletion of the ozone layer, the climate change, the deterioration of air quality, the acid rain, the worsening quality of surface and ground water, the surface loss of rainforests and many other negative aspects of our thoughtless actions. For the measurement of sulphur concentration, we chose locality surrounding the power plant Vojany, where we identified two locations for mounting our stands. The first place was the village Tušice, and the second one the area of AMS Leles. This is where we planted in alkaline strips in stands used for this purpose and by the sorption – cumulative method we evaluated concentrations of sulphur amount collected on the strips. In the period 2012–2014, we conducted experiments in regular 30-day intervals; we performed 104 analyses of filter plates using the sorption-cumulative method. The current position of some habitats infestation causes damage to various parts of environment. Therefore, we consider it relevant to continue in monitoring this affliction and quantifying the extent of its negative effects. The proposed procedure with the possibility of a retrospective determination of concentrations of SO2 using mathematical modelling can also be used for the determination of old burdens.","PeriodicalId":247321,"journal":{"name":"Acta Horticulturae et Regiotectuare","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127343261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
