Opis:
The research on the content of polycyclic aromatic hydrocarbons (PAHs) in soil and grass (Lolium perenne L.) was carried out on samples collected in the city of Białystok, in north-eastern Poland. The test samples came from green belts in the vicinity of communication routes, differentiated in terms of the surrounding buildings and infrastructure and characterized by a different car traffic intensity. The highest total concentration of all sixteen PAHs in soil and grass samples was found near a large intersection at Nicholas Copernicus Street, one of the most important communication routes connecting two parts of the city. In the aboveground parts of the studied grass samples, benzo[a]pyrene was the most abundant, its content ranging from 53.8 µg/kg DM up to 91.7 µg/kg DM. On the other hand, in soil samples, much higher benzo[a]pyrene content was found, and the dominance of this compound was observed in almost every measurement location. Based on the obtained results, it was found that car traffic is a significant source of PAH emissions to the urban soil environment and urban greenery. The squares and green belts located along communication routes and intersections are the most exposed to pollution.

Opis:
Replicated three times, the research was conducted in the experimental field between 2011 and 2014. Three soil conditioners with the following trade names: UGmax, Eko- Użyźniacz, and Humus Active Papka were used in the experiment, separately or together with NPK fertilisers. They were all used on plots sown with two species of grass, Dactylis glomerata of the Bora variety and Lolium perenne of the Info variety. The plant material from both grass species was tested for the concentration of ADL fraction (% DM), cellulose (% DM), and hemicellulose (% DM). It was found that the concentration of cellulose, hemicelluloses, and the ADL fraction was significantly higher in the biomass of Dactylis glomerata than in the biomass of Lolium perenne. The grass from the plot with the UGmax soil conditioner applied had the highest amount of cellulose and hemicellulose. The lowest amount of those organic compounds was found in the grass treated with UGmax together with mineral fertilisers and in plants treated with Humus Active, together with mineral fertilisers. However, the fertilisers and conditioners did not increase the ADL content in both grass species.

Opis:
The paper contains the results of field and laboratory experiments on three Lolium perenne L. turfgrass cultivars (Gazon, Nira and Sandra) at Malopolska Plant Breeding Station (HBP) in Skrzeszowice near Krakow (220 m a.s.l.) conducted in the years 2006–2008. The analyses assessed the effect of doses of mineral fertilization with nitrogen (60, 90 and 120 kg N ha–1) applied at early spring, the start of the earing stage and autumn on the seed yield. The highest yield was monitored by the inflorescence shoot density of cv. Nira (1895 shoots/m2), cv. Gazon (1976 shoots/m2) and cv. Sandra (2098 shoots/m2). Fertilization dose of 90 kg N ha–1 applied three times effected the most considerably the number of spikelets per ear and the efficiency of seed settling on the ear: from 73 % (cv. Nira) to 76 % (cv. Sandra). The highest seed yield was obtained as a result of the 120 kg N ha–1 fertilizations applied three times.
Praca zawiera zestawienie wyników badań polowych i laboratoryjnych przeprowadzonych w Stacji Małopolskiej Hodowli Roślin - HBP w Skrzeszowicach koło Krakowa (220 m n.p.m.) w latach 2006-2008 z trzema gazonowymi odmianami życicy trwałej (Gazon, Nira, Sandra). W badaniach poddano ocenie wielkość dawki nawożenia mineralnego azotem (60, 90, 120 kg N ha-1) oraz termin jego stosowania (wczesnowiosenny, początek kłoszenia i jesienny), na wielkość plonu nasion. W przeliczeniu na 1 m2 uzyskanie największego plonu nasion zapełniała obsada pędów kwiatowych: 1895 u odmiany Nira, 1976 u odmiany Gazon oraz 2098 u odmiany Sandra. Nawożenie azotem w dawce 90 kg N ha-1 zastosowanej w trzech terminach: wczesnowiosennym, na początku kłoszenia i jesiennym najbardziej zwiększało liczbę kłosków w kłosie oraz efektywność osadzania nasion w kłosie od 73 % u odmiany Nira do 76 % u odmiany Sandra. Największy plon nasion uzyskano pod wpływem dawki 120 kg ha-1, zastosowanej w trzech terminach: wczesnowiosennym, na początku kłoszenia i jesiennym.

Opis:
The ergot (Claviceps purpurea) incidence in seed samples of Poa pratensis, Lolium perenne, L. multiflorum, Festuca rubra and F. pratensis cultivars originating from different regions of grass cultivation in Poland was detected in 1999 – 2002. Each year, about hundred twenty cultivars of different species were tested. It was found that number of seed replaced by sclerotia significantly varied and depended on the year of seed harvest, species and cultivar tested and region of grass grown for seed. The highest level of Claviceps purpurea sclerotia almost for all grass species was detected in 1999. The highest number of seed replaced by sclerotia was found in sowing material of Poa pratensis for all years of testing. Ergot in seed lots of L. multiflorum and F. pratensis were detected at trace levels. Differences in susceptibility to Claviceps purpurea among cultivars were observed. However, significant variation in occurrence of ergot sclerotia were noted for the same cultivar harvested in different region of Poland. It was found that size of sclerotia depended on the host - grass species and the year of seed harvest. Significant differences  were noted particularly in the length and weight of sclerotia.

An important role in the agricultural agrocenosis is attributed to entomopathogenic fungi. They limit the occurrence of certain populations of soil pests and insects overwintering in the soil environment, or held in the pupation. Fungi are the only pathogens of arthropods witch have the ability to infect plant pests directly by body. However, bacteria are the largest group of microorganisms inhabiting the soil. The aim of this study was to compare the species composition and the severity of the occurrence of entomopathogenic fungi in soils of monoculture crops perennial ryegrass (Lolium perenne L.). The material consisted of soil samples taken from the experimental research conducted in two experimental stations of the Central Research Centre for Cultivar. The fungi isolated from soil insecticides using a method developed by the selective medium.

Opis:
Drought is the main environmental factor hampering world agriculture production. In the face of warmingclimate and reduced fresh water resources it become obvious that search for any factors decreasing water useis strongly recommended. Turf grasses able to withstand drought period longer could be recommended for turfareas as parks, lawns, home gardens etc. and relatively lower amounts of water should ensure satisfactory turfquality. Therefore, twelve turf varieties from three major cool-season turf grass species: perennial ryegrass(Lolium perenne L.), Kentucky bluegrass (Poa pratensis L.) and red fescue (Festuca rubra L.) were tested inglasshouse pot experiment and in the laboratory for determination of their relative ability to withstand greenlonger in the face of water deficit.The different response of the examined forms to drought was noted. Conditions that favor fast water depletionwere the most suitable for the expression of water deficit-related traits. Therefore, sandy mixture of 16%volumetric moisture content at field water capacity was mostly suitable for observation of the variation oftested forms. Turf condition of Kentucky bluegrass, as contrary to red fescue, was strongly connected with thesoil moisture. Different manifestation of drought resistance was observed in tested species. Kentucky bluegrass,as rather no resistant to drought, exposed low level of drought avoidance. Red fescue was able to survivedrought mainly due to leaf blades resistant to desiccation. In perennial ryegrass some other mechanismsevolved to survive drought. Early leaf wilting and senescence contributes to nutrient remobilization duringdrought and avoids large water loses during the transpiration. Therefore, perennial ryegrass turf was able toregenerate better after drought, as compared to the other tested grass species.Search for new turf forms should focus on searching for ability to maintain acceptable conditions longer ina presence of increasing water deficit. It will then reduce the duration of period of poor turf conditions andfurther, turf water demands.

Opis:
In pot experiments carried out in 2005 and 2006, tolerance to sodium chloride salinity of 4 cultivars of perennial ryegrass (Lolium perenne) (‘Nira’, ‘Stadion’, ‘Ronija’, ‘Darius’) was studied. Three concentrations of NaCl in medium (earth + sand): 0.0 mM (control); 50 mM; 100 mM, were used in the investigations. In three successive crops of grass, fresh weight yield of leaves, stomatal conductance, photosynthesis intensity, content of chlorophyll and PS II maximum quantum yield (Fv/Fm) were determined. The obtained results showed that perennial ryegrass is a species tolerant to NaCl salinity. Among the studied cultivars, cv. ‘Ronija’ showed the highest tolerance, whereas cv. ‘Nira’ showed the lowest. The growth of perennial ryegrass plants under salinity conditions was limited by low stomatal conductance of leaves and photosynthesis, but not by the photosynthetic activity of chlorophyll and its contents.
W doświadczeniach wazonowych prowadzonych w 2005 i 2006 roku badano tolerancję na zasolenie chlorkiem sodu 4. odmian życicy trwałej (‘Nira’, ‘Stadion’, ‘Ronija’, ‘Darius’). W badaniach zastosowano 3 stężenia NaCl w podłożu (ziemia + piasek): 0,0 mM (kontrola); 50 mM; 100 mM. W trzech kolejnych zbiorach trawy określono: plon świeżej masy liści, przewodność szparkową, intensywność fotosyntezy, zawartość chlorofi lu, maksymalną wydajność kwantową PS II (Fv/Fm). Uzyskane wyniki wykazały, że życica trwała jest gatunkiem tolerancyjnym na zasolenie NaCl, a w obrębie badanych odmian najwyższą tolerancją charakteryzowała się odm. ‘Ronija’, a najniższą odm. ‘Nira’. Wzrost roślin życicy w warunkach zasolenia ograniczany był niską przewodnością szparkową i fotosyntezą, a nie aktywnością fotosyntetyczną chlorofilu (Fv/Fm) i jego zawartością.

Opis:
The present study was designed to assess phytostabilization strategies for the treatment of soil co-contaminated by increasing levels of copper with the application mineral amendments (chalcedonite, zeolite, dolomite). From the results it will be possible to further elucidate the benefits or potential risks derived from the application of different types of mineral amendments in the remediation of a copper contaminated soil. A glasshouse pot experiment was designed to evaluate the potential use of different amendments as immobilizing agents in the aided phytostabilization of Cu-contaminated soil using ryegrass (Lolium perenne L.). The content of trace elements in plants and total in soil, were determined using the method of spectrophotometry. All of the investigated element contents in the tested parts of L. perenne were significantly different in the case of applying mineral amendments to the soil, as well as increasing concentrations of copper. The greatest average above-ground biomass was observed for soil amended with chalcedonite. In this experiment, all analyzed metals accumulated predominantly in the roots of the tested plant. In general, applying mineral amendments to soil contributed to decreased levels of copper concentrations.
Niniejsze badania zostały przeprowadzone w celu oceny procesu wspomaganej fitostabilizacji gleby zanieczyszczonej wzrastającymi dawkami miedzi przy zastosowaniu dodatków mineralnych (chalcedonit, zeolit, dolomit). Na podstawie otrzymanych wyników badań można wyjaśnić korzyści jak i potencjalne zagrożenia wynikające ze stosowania różnego rodzaju dodatków mineralnych w celu immobilizacji zanieczyszczenia gleby miedzią. Eksperyment wazonowy został przeprowadzony z wykorzystaniem rośliny testowej jaką była życica trwała (Lolium perenne L.) odmiany Bokser. Zawartość miedzi w poszczególnych organach rośliny (część nadziemna, korzenie) oraz w glebie określono przy wykorzystaniu metody spektrofotometrii. Koncentracja miedzi w poszczególnych organach L. perenne zależała od rodzaju wprowadzonego do gleby dodatku mineralnego oraz dawki miedzi. Największy przyrost biomasy zaobserwowano w przypadku dodatku do gleby chalcedonitu. W przeprowadzonym eksperymencie miedź gromadziła się głównie w korzeniach rośliny testowej. Zastosowanie dodatków mineralnych miało tendencję do zmniejszania całkowitej zawartości miedzi w glebie, w porównaniu do kontroli.

Opis:
The effect of soil drought on leaf water content, proline content, and the activity of guaiacol (GuPX) and ascorbate (APX) peroxidases as well as the level of lipid peroxidation were investigated in leaves of drought resistant red fescue (Festuca rubra) and drought sensitive perennial ryegrass (Lolium perenne). Plants were grown under glasshouse conditions in soil pot culture. 26 day-old grasses were exposed to drought by withholding irrigation for 18 days. Water content in leaves of perennial ryegrass decreased more than in red fescue throughout the experimental period. On the other hand, proline content (PC) was higher in red fescue. The activity of APX and GuPX increased in leaves of red fescue, while it did not change in perennial ryegrass. Our data demonstrate that both red fescue and perennial ryegrass were able to survive applied drought, as shown by a lack of stress-induced lipid peroxidation and hence no evidence of oxidative damage. We speculate, that the observed drought stress tolerance at cellular level was associated with the ability to accumulate proline, and to maintain high activity of APX and GuPX, resulting in protection against oxidative damage and lipid peroxidation. It seems that this mechanism works better in red fescue.
