In future, grass swards need to be adapted to climate change and interactions of management and site are becoming more important. The persistence of Lolium perenne on peatland or during dry periods is limited and alternative forage species are required. We tested the performance of a modern variety of Festuca arundinacea and Phleum pratense as an alternative to Lolium perenne on clay, peat, and sandy soils. Each of these grasses was sown as main species in mixture with Poa pratensis and Trifolium repens and the mixtures were subjected to different frequencies of defoliation. Differences in yield proportions in the third year were significantly influenced by main species, site and their interaction. Remaining mass proportions of main species after three years were smallest on peat; on all sites Festuca arundinacea showed the highest persistence and largest yield, followed by Lolium perenne. Mass proportions of Phleum pratense were small on peat soils and Phleum had been replaced there by Holcus lanatus, and by Lolium perenne and Poa pratensis on the clay and sandy soils. We conclude that the choice of grass species in mixtures is a management tool to control stability and productivity of grass swards under specific site conditions.

Forty samples of grass silages, made from the five most widely used grass species in ruminant nutrition (<I>Dactylis glomerata</I> L.,<I>Phleum pratense</I> L., <I>Lolium perenne</I> L., <I>Festuca arundinacea</I> L. and hybrid Felina) were tested in the present study. These grass species conserved by an ensiling process were compared among each other according to dry matter (DM) rumen degradability parameters (<I>a</I> = portion of DM solubilized at initiation of incubation, <I>b</I> = fraction of DM potentially degradable in the rumen, <I>c</I> = rate constant of disappearance of fraction b and ED<sub>DM</sub> = effective degradability of DM, estimated for each ingredient assuming the rumen solid outflow rates of 0.02 (ED<sub>DM2</sub>), 0.05 (ED<sub>DM5</sub>) and 0.08 (ED<sub>DM8</sub>) h<sup>–1</sup>). Based on the chemical composition of grass silages the regression equations for prediction of ED<sub>DM</sub> were evaluated. The influence of the ensiling process on dry matter degradability parameters was also assessed. The best values of ED<sub>DM</sub> were determined for <I>Lolium perenne</I> (ED<sub>DM2</sub> = 753.2, ED<sub>DM5</sub> = 631.1 and ED<sub>DM8</sub> = 567.7 g/kg DM). The best predictor was NDF (<I>R</I><sup>2</sup>-values of 0.757 (ED<sub>DM2</sub>), 0.863 (ED<sub>DM5</sub>) and 0.906 (ED<sub>DM8</sub>)). Using two predictors the accuracy level increased. The combination of CF and NDF gave <I>R</I><sup>2</sup>-values 0.892, 0.920 and 0.929 for ED<sub>DM2</sub>, ED<sub>DM5</sub> and ED<sub>DM8</sub>, respectively. The regression equations based on the most important grass species harvested in different vegetation periods seem to be a useful tool for practical use. No significant <I>P</I> < 0.05) effect of the ensiling process in relation to dry matter rumen degradability parameters was proved.

Resistance of common European grasses to diesel oil and petroleum pollution is not well-known. Therefore, this study aimed at determining the level of resistance of selected grasses to pollution by diesel and petroleum using the pot experiment. The achieved results were compared with those determined for grasses grown on the non-polluted soil. Soil pollution with the tested products was found to significantly decrease the yield of all grasses, with the decrease being lower upon soil pollution with petroleum than with diesel oil. The most resistant to the pollution with diesel oil and petroleum were Phleum pratense L., Lolium perenne L. and Lolium × hybridum Hausskn. The degradation of particular groups of polycyclic aromatic hydrocarbons (PAHs) depended on their chemical properties, on the type of pollutant and grass species. The greatest degradation was determined in the case of BTEX, C<sub>6</sub>–C<sub>12</sub> benzines as well as 2- and 3-ring hydrocarbons, whereas the lowest in the case of 5-and 6-ring hydrocarbons and C<sub>12</sub>–C<sub>25</sub> oils. The most useful species in the remediation of soils polluted with diesel oil and petroleum turned out to be: Lolium perenne L., Lolium × hybridum Hausskn and Phleum pratense L., whereas the least useful appeared to be: Festuca rubra, Dactylis glomerata L. and Poa pratensis L.

Abstract. Species diversity in grasslands usually declines with increasing input of nitrogen from fertilizers or atmospheric deposition. Conversely, species diversity may also impact the build-up of soil and plant nitrogen pools. One important pool is NH3/NH4+ which also can be exchanged between plant leaves and the atmosphere. Limited information is available on how plant-atmosphere ammonia exchange is related to species diversity in grasslands. We have here investigated grass species abundance and different foliar nitrogen pools in 4-year-old intensively managed grassland. Apoplastic pH and NH4+ concentrations of the 8 most abundant species (Lolium perenne, Phleum pratense, Festuca pratensis, Lolium multiflorum, Poa pratensis, Dactylis glomerata, Holcus lanatus, Bromus mollis) were used to calculate stomatal NH3 compensation points. Apoplastic NH4+ concentrations differed considerably among the species, ranging from 13 to 117 μM, with highest values in Festuca pratensis. Also apoplastic pH values varied, from pH 6.0 in Phleum pratense to 6.9 in Dactylis glomerata. The observed differences in apoplastic NH4+ and pH resulted in a large span of predicted values for the stomatal NH3 compensation point which ranged between 0.20 and 6.57 nmol mol−1. Three species (Lolium perenne, Festuca pratensis and Dactylis glomerata) had sufficiently high NH3 compensation point and abundance to contribute to the bi-directional NH3 fluxes recorded over the whole field. The other 5 grass species had NH3 compensation points considerably below the atmospheric NH3 concentration and were thus not likely to contribute to NH3 emission but only to NH3 uptake from the atmosphere. Evaluated across species, leaf bulk-tissue NH4+ concentrations correlated well (r2=0.902) with stomatal NH3 compensation points calculated on the basis of the apoplastic bioassay. This suggests that leaf tissue NH4+ concentrations combined with data for the frequency distribution of the corresponding species can be used for predicting the NH3 exchange potential of a mixed grass sward.

Twelve cultivars representing eight grass species were each grown in a sand/vermiculite medium in the greenhouse, fed six solutions varying in chloride content for 140 days, and cut at lawn height. Six harvests were obtained and analyzed for chloride uptake. Visual ratings and yields indicated that the grasses tolerate relatively high chloride levels for a considerable time. Chloride uptake increased with time and increasing chloride content of the solutions. Uptake was less from alkaline than from acid solutions. Highland bentgrass (Agrostis tenuis Sibth.), Italian ryegrass (Lolium multiflorum Lam.) and timothy (Phleum pratense L.) were the least tolerant, while Norlea perennial ryegrass (Lolium perenne L.) and Kentucky 31 tall fescue (Festuca arundinacea Schreb.) were the most tolerant to chlorides. Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.) were intermediate in this respect.

The most frequent way to establish turfgrass in the climatic conditions of the Czech Republic is sowing during spring period. The seedlings are endangered by lack of soil moisture and by high temperatures if irrigation is no available. One of the possibilities how to increase probability of successful turfgrass establishment in warm areas which suffer by low amount of precipitation is autumn term of sowing.Eight grass species and subspecies and two legumes were sown in three autumn terms (September, October and November) during 2009 and 2010. The shortest time for seedling emergence was found in average of all terms atMedicago lupulinaandTrifolium repens(9 days).Lolium perenne(14)and Festuca arundinacea(17) were the fastest emerged grasses. On the other hand the longest emergence time was realised atPoa pratensis(23),Festuca rubra ssp. trichophyla(22)andFestuca ovina(21). Plants sown in September emerged in 10 days, in October 12 and in November in 29 days. September term was suitable for all used species but November term underwent most successfullyFestuca rubrassp.commutata(23% soil cover in April next year)andLolium perenne(19%). November term was not acceptable for legumes.

An average dry matter yield structure (three cuts per growing season) in relation to agronomically valuable characteristics of six forage grass species and a year of herbage utilization was studied over the period of 1989&ndash;2002 in Lithuania. The most productive species of the first cut of two years of herbage utilization were Phleum pratense (P &lt; 0.01) and Festulolium hybrids (P &lt; 0.05) (average dry matter yield were 7.42 and 6.66 t/ha, respectively), moderately productive &ndash; Festuca pratensis, Dactylis glomerata and Lolium perenne (5.58, 5.42 and 5.20 t/ha), significantly lower (P &lt; 0.01) yielding was Poa pratensis (4.19 t/ha). During two years of herbage utilization Dactylis glomerata produced significantly (P &lt; 0.01) higher dry matter yield of aftermath &ndash; 7.30 t/ha. Other grass species were ranked in the following order: Festulolium hybrids 5.85 t/ha, Festuca pratensis 4.94 t/ha, Poa pratensis 4.57 t/ha, Lolium perenne 4.48 t/ha, and Phleum pratense 3.92 t/ha. Dactylis glomerata and Poa pratensis distinguished by the highest aftermath percent in the structure of the annual dry matter yield (57.7 and 52.2%). Phleum pratense formed an especially poor aftermath &ndash; only 34.6%. An average annual dry matter yield data analysis of two years of herbage utilization over the period of 1989&ndash;2002 showed that Dactylis glomerata and Festulolium hybrids were most productive (P &lt; 0.01) species.

Botanical composition of grasses is one of the most important indicators the biological value and quality of the obtained hay and pasture forage, the longevity of hayfi elds and pastures depend on. The issue of changing the botanical composition of agrophytocenoses is especially important in the context of global climate change, which in recent decades is also manifested in the territory of Ukraine, as it is possible to establish the most adapted species of legumes and cereals to adverse weather conditions and to identify eff ective technological methods of managing these processes for maximum conservation economically valuable species in the herbage. The purpose of the research is to establish the infl uence of diff erent ways of sowing of clover and alfalfa cereal crops agrophytocenoses on the formation of their botanical composition. Field studies have established diff erent eff ects of conventional in-line, cross-section and cross-sectional methods of sowing on the formation of botanical composition of grass mixtures of clover meadow (Trifolium pratense) varieties Sparta and Pavlyna with timothy meadow (Phleum pratense) and fenugreek multifl oral (Lolium multifl orum) and of agrophytocenoses of alfalfa of Sinyukha and Seraphima sowing varieties with reed fire (Festuca arundinacea Schreb) and middle wheatgrass (Elytrigia intermedia). For the average of four years of life of clover and alfalfa cereal crops agrophytocenoses, the highest proportion of legume component was observed with split-cross sowing – 51.6 % for Sparta, 53.1 % for Pavlyna, 60.3 % for Seraphima and 61.6 % for the Sinyukha variety. In the fourth year of life (the third year of use) of sowed leguminous-cereals agrophytocenoses, the preservation of the legume component was 14.6–15.5 % in clover-cereals grass mixtures with the Sparta variety and 16.0–16.8 % with the Pavlyna variety. In alfalfa grasslands, these indicators were 54.0–55.1 % with Seraphim and 55.0–56.2 % with Sinyukha. Among the studied varieties of clover meadow and alfalfa sowing proved better in the conditions of the Forest Steppe of western Pavlyna and Sinyukha. Cross-sectional and divided cross-sectional sowing of legumes and cereals mixtures proved to be better compared to conventional row crops in terms of conservation of economically valuable grass species. Key words: agrophytocenosis, botanical composition, clover meadow, alfalfa sowing, sowing methods.

Studies were conducted on the host plants of four billbug species (Coleoptera:Curculionidae: Sphenophorus parvulus Gyllenhal, S. venatus Chitt., S. inaequalis Say, and S. minimus Hart) found on New Jersey turfgrasses. A collection of 4803 adults from pure stands of various turfgrasses revealed all four billbugs on Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb.), and perennial ryegrass (Lolium perenne L.), and S. parvulus, S. venatus, and S. minimus on Chewings fescue (F. rubra L. ssp. commutata Gaud.). Since the presence of larvae, pupae, or teneral adults more accurately indicates the host status of a grass species, immature billbugs were collected from plugs of the various grass species and reared to adults for identification. All four species were reared from immature billbugs found in Kentucky bluegrass turf; immatures of S. venatus, S. inaequalis, and S. minimus were found in tall fescue; S. venatus and S. minimus in perennial ryegrass; and S. inaequalis in strong creeping red fescue (F. rubra L. ssp. rubra). A laboratory experiment was also conducted in which billbug adults were confined in petri dishes with either Kentucky bluegrass, perennial ryegrass, tall fescue, or bermudagrass (Cynodon dactylon Pers.). Only minor differences were found between the four grasses in billbug survival, number of eggs laid, and amount of feeding. In general, bermudagrass was the least favored host and the other grasses were equally adequate hosts. The results of this study indicate a need for updating host-plant lists of these four billbug species.

Recent discussion about pasture persistence concentrates on pastures based on perennial ryegrass, the most commonly used grass species. This paper raises the question as to whether some of the causes of poor pasture persistence are due to perennial ryegrass being used in environments to which it is not suited. The adaptation to environmental stresses, particularly water, temperature and nutrient deficiencies, in different regions of New Zealand of tall fescue, cocksfoot, phalaris, and lucerne are discussed, and how this impacts on persistence advantages over perennial ryegrass. Keywords: persistence, pasture, Dactylis glomerata, Festuca arundinacea, Lolium perenne, Medicago sativa, Phalaris aquatica

High-throughput sequencing technologies were used to identify plant viruses in cereal samples surveyed from 2012 to 2017. Fifteen genome sequences of a tenuivirus infecting wheat, oats, and spelt in Estonia, Norway, and Sweden were identified and characterized by their distances to other tenuivirus sequences. Like most tenuiviruses, the genome of this tenuivirus contains four genomic segments. The isolates found from different countries shared at least 92% nucleotide sequence identity at the genome level. The planthopper Javesella pellucida was identified as a vector of the virus. Laboratory transmission tests using this vector indicated that wheat, oats, barley, rye, and triticale, but none of the tested pasture grass species (Alopecurus pratensis, Dactylis glomerata, Festuca rubra, Lolium multiflorum, Phleum pratense, and Poa pratensis), are susceptible. Taking into account the vector and host range data, the tenuivirus we have found most probably represents European wheat striate mosaic virus first identified about 60 years ago. Interestingly, whereas we were not able to infect any of the tested cereal species mechanically, Nicotiana benthamiana was infected via mechanical inoculation in laboratory conditions, displaying symptoms of yellow spots and vein clearing evolving into necrosis, eventually leading to plant death. Surprisingly, one of the virus genome segments (RNA2) encoding both a putative host systemic movement enhancer protein and a putative vector transmission factor was not detected in N. benthamiana after several passages even though systemic infection was observed, raising fundamental questions about the role of this segment in the systemic spread in several hosts.
