The aim of this study is to determine adaptation and quality parameters of some cool season turfgrass cultivars and species, In the scope of this study, leaf form, variation of leaf colour according to the seasons, tiller number, thinning ratio, weed ratio and general appearance of the species were determined. The experiment was established according to confounding design with four replications in Samsun Conditions at November, 2010. According to 1000 seed weight and characteristics of the plants seeding ratios were determined as pure and viable seed as follows; Lolium perenne 40 g m-2, Festuca rubra var. rubra and Festuca rubra var. commutata 30 g m-2, Festuca arundinacea 40 g m-2, Poa pratensis 20 g m-2, Festuca rubra trichophylla 30 g m-2, Agrostis stolonifera and Agrostis tenuis 5 g m-2, Festuca ovina 25 g m-2. According to the results obtained from this study it was determined that species/cultivars have some superiority to each other because of their different morphological and physiological characteristics. When we consider weed competition, Lolium perenne and Festuca arundinaceae cultivars have to be added to the mixture in order to decrease weed competition. There was colour variation distinctively depending on the seasons for all species. But, compare to the others, cultivars of Agrostis sp. and Poa pratensis cultivars have the potential to keep leaf colour in different seasons. Leaf form and appearance of Festuca rubra, Poa trivialis and Festuca ovina are better than the others. In order to keep good conditions of turfgrass areas, especially after cutting in summer period, Poa pratensis and Poa trivialis should added in mixtures to get benefit their higher regenerating power.

Celem prezentowanych badań była ocena początkowego tempa wzrostu wybranych 5 gatunków traw, w celu określenia ich przydatności do szybkiego i skutecznego zadarniania przydrożnych skarp w dwóch terminach wysiewu, (wiosenny i późnojesienny). Badania przeprowadzono na skarpie usytuowanej wzdłuż drogi krajowej S17. Pomiary długości korzeni i wysokości siewek każdego gatunku wykonano w 10, 20, 30, 40, 50 i 60. dniu od daty siewu. Wykazano, że w warunkach prowadzenia doświadczenia gatunki traw różnią się tempem początkowego wzrostu. Terminy siewu miały istotny wpływ na tempo wydłużania korzeni i wzrostu siewek badanych gatunków traw, bowiem na obiektach z późnojesiennym terminem siewu wszystkie gatunki i odmiany charakteryzowały się najkrótszymi korzeniami i najniższymi siewkami. W obu terminach siewu, niezależnie od roku prowadzenia doświadczeń, siewki L. perenne charakteryzowały się najdłuższymi korzeniami i najwyższymi siewkami w porównaniu z pozostałymi gatunkami. Z kolei siewki P. pratensis w obu powtórzeniach charakteryzowały się najkrótszymi korzeniami i najniższymi siewkami w porównaniu z pozostałymi gatunkami.

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.

Lipid Diffusion

Leaf slices of the sethoxydim sensitive grasses Poa pratensis and Festuca ovina and the sethoxy- dim resistant grasses Poa annua and Festuca rubra take up the herbicide at similar rates. Uptake is almost linear with concentration up to 2 mᴍ, independent of light and little affected by tempera­ture between 0 and 25 °C. Uptake is highly pH sensitive. At pH 7.0 rates of uptake are only about 20% of the rates observed at pH 3.5. Time course of uptake suggests a rapid equilibration of the compartments taking up the herbicide within 2 h. It is suggested that sethoxydim uptake by the grass-leaf tissue is a nonspecific process involving passive lipid diffusion and lipid equilibration of the non-dissociated weak acid sethoxydim (pKa = 4.6).

Парк у с. Піківець Уманського району Черкаської області було закладено у 50-60-х роках ХХ ст. у центрі села, а саме біля сільського клубу. Насамперед потрібно провести санітарне рубання та обрізування дерев. Пропонуємо підсіяти мавританський газон, а в місці, де зростає пирій повзучий (Elytrigia repens L.), повністю замінити травостій на газон. Згідно з проектом розширюється стежкова мережа. Запропоновано створення доріжок з бетонної тротуарної плитки завширшки 0,75 та 1,5 м. Деякі стежки виконуватимуть транзитну роль, а деякі сполучатимуть окремі елементи парку. З малих архітектурних форм у парку встановлюємо альтанку для відпочинку. Також запропоновано збільшити кількість лавок, додавши дугоподібну лавку на круглому майданчику, у центрі якого розміщуватиметься клумба. Позаду кругової лавки, у північно-східній частині парку запроектовано створення декоративної групи з кущів. Асортимент рослин для цієї групи включає: Berberis thunbergii DC, Forsythia europaea Deg. et Bald., Pyracantha coccinea (L.) M. Roem, Syringa vulgaris L., Cotoneaster horizontalis Decne. Для клумб використовуємо цибулькові ранньоквітучі види, а також переважно тіньовитривалі багаторічники. Рекомендуємо створити мавританський газон, до складу якого входять: костриця червона (Festuca rubra L.), райграс пасовищний (Lolium perenne L.), тонконіг лучний (Poa pratensis L.), мак польовий (Papaver rhoeas L.), льон великоквітковий (Linum grandiflorum Desf.), ромашка лікарська (Matricaria recutita L.), низькорослі сорти космеї (Cosmos Cav.), чорнобривці мексиканські (Tagetes tenuifolia Сav.), гіпсофіла повзуча (Gypsophila muralis L.), гіпсофіла витончена (Gypsophila elegans M. Bieb.).

Yellow nutsedge (Cyperus esculentusL.) control with herbicides was evaluated with and without competition from turfgrasses. Postemergence applications of cyperquat (1-methyl-4-phenylpryidinium) provided safe selective control of yellow nutsedge in Kentucky bluegrass (Poa pratensisL. ‘Merion’), perennial ryegrass (Lolium perenneL. ‘Manhatten’), and red fescue (Festuca rubraL. ‘Pennlawn’). Pre- and post-emergence applications of perfluidone {1,1,1-trifluoro-N-[2-methyl-4-(phenylsulfonyl)phenyl] methanesulfonamide} controlled yellow nutsedge when rainfall or irrigation was adequate for good turfgrass growth. Under dry conditions, perfluidone slightly injured Kentucky bluegrass and gave poor control of yellow nutsedge. Bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-(4)3H-one2,2-dioxide] was less effective than cyperquat or perfluidone for yellow nutsedge control and required split applications. Bentazon did not injure Kentucky bluegrass. Napropamide [2-(α-naphthoxy)-N,N-diethylpropionamide] and Vel 3973 [N-(2,4-dimethyl-5-{[(trifluoromethyl)sulfonyl]amino}phenyl)acetamide] did not provide adequate yellow nutsedge control. Vel 5052 {2-chloro-N-(2,6-dimethyl-phenyl-N-[(1,3-dioxolan-2-yl)methyl] acetamide}showed promise for yellow nutsedge control.

Repeated Freezing

Prior exposure to freezing can increase the subsequent freezing tolerance of plants and reduce the severity of injury. However, it is unknown how freezing memory influences plant productivity. We investigated the effects of repeated freezing events over multiple seasons on the biomass of Bromus inermis, Lolium perenne, Festuca rubra, Plantago lanceolata, and Poa pratensis. The plants were exposed to different combinations of freezing in the early spring, late spring, or fall (2017), as well as the following spring (2018); control plants were frozen only once, along with all of the other treatments, during the spring of 2018. Bromus inermis that experienced every freeze, and the plants frozen in both the early and late spring, had higher biomass than the controls. Similarly, Poa pratensis plants frozen in both the early and late spring had higher biomass than the controls. In contrast, Festuca rubra plants frozen in early spring and fall had lower root biomass than the control plants, and Lolium perenne plants that experienced every freeze had lower root biomass than the controls. Variation among species in repeated freezing responses could have important consequences for the relative abundances of herbaceous species in northern temperate regions.

Postemergence applications of BAS 9052 OH, {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one}, at 0.25 and 0.5 kg ai/ha were made to 27 temperate and 28 tropical species ofGramineae. Annual bluegrass (Poa annuaL. ♯3POAAN) and rattail fescue (Festuca myurosL. ♯ VLPMY) were resistant to these rates of BAS 9052 OH. Five species of fescue and three species of bluegrass received postemergence applications of BAS 9052 OH at rates of 0.1 to 6.4 kg ai/ha. The germination of seeds and the subsequent growth of the seedlings of these species as influenced by various concentrations of BAS 9052 OH were also studied. Meadow fescue (Festuca pratensisHuds. ♯ FESPR), tall fescue (Festuca arundinaceaSchreb. ♯ FESAR), Kentucky bluegrass (Poa pratensisL. ♯ POAPR), and rough-stalked meadowgrass (Poa trivialisL. ♯ POATR) were most susceptible; annual bluegrass was somewhat less resistant; hard fescue (Festuca longifoliaThuill) was resistant; red fescue (Festuca rubraL. ♯ FESRU) and rattail fescue were very resistant.
