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.

The effect of Lolium perenne L., Festuca rubra L., Festuca arundinacea Schreb., Poa pratensis L. and Poa annua L. aqueous extracts on germination rate and total germinability of Poa annua L. seeds and length of Poa annua L. leaves and roots was studied in a laboratory experiment. Germination of seeds was conducted in the growth chamber at the light and temperature regime – day/night – 12/12 hours, 23/15˚C, rh 70 %, for 42 days. Extracts significantly affected the total germinability and germination rate of Poa annua L. seeds (p = 0.000). The lowest germinability (27.3 ± 7. 1 %) and germination rate (0.7 ± 0.2 seeds per day) had Poa annua L. seeds germinated in Poa pratensis L. aqueous extract. Used extracts (except for Festuca rubra L. extract) had significantly inhibitory effect on length of Poa annua L. roots in comparison with control variant. The positive effect of extract from Lolium perenne L. and Festuca rubra L. (not– significant) and the negative effect of extract from Poa pratensis L. and Poa annua l. (significant) were apparent on length of Poa annua L. leaves.

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.

Turfgrass Establishment

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.

Effect Of Water

<p>The allelopathic effect of plants is one of the least known factors determining the stability of lawn swards. Leaves are a rich source of allelopathic substances. Washed out by rain or dew drops, or released during biomass decomposition, these substances can impact plants. In practice, cut sward is often left on the lawn surface and can have an allelopathic effect on regrowing plants. The effect of released allelochemicals depends on many factors, including their concentration. Hence, in order to maintain the high functional properties of the lawn, information is needed on the critical concentrations of allelochemicals inhibiting plant growth and development. Laboratory research was thus undertaken (on Petri dishes) to evaluate the effect of various water extracts of leaves of selected lawn grass cultivars. The following cultivars were the donors: 'Areta', 'Nimba', 'Olivia' (<em>Festuca rubra</em>)<em>; </em>'Espro', 'Pintor' (<em>F. ovina</em>),and 'Asterix' (<em>F. arundinacea</em>)<em>, </em>while the acceptors were: 'Niwa' (<em>Agrostis capillaris</em>), 'Asterix' (<em>Festuca arundinacea</em>), 'Espro' (<em>F. ovina</em>), 'Areta' (<em>F. rubra</em>), 'Stadion' (<em>Lolium perenne</em>), and 'Bila' (<em>Poa pratensis</em>) – the species frequently sown in lawns. In the control treatments, distilled water was applied to the substrate.</p><p>The experiment revealed that the effect of water extracts of leaves varied depending on their concentration and donor variety as well as the sensitivity of the acceptor (the test plant). In comparison with the control treatments, the strongest negative impact was caused by the cultivars 'Olivia' (<em>F. rubra</em>)and 'Pintor' (<em>F. ovina</em>), followed by 'Asterix' (<em>F. arundinacea</em>)<em>.</em> Among the acceptors, the greatest sensitivity to the presence of allelochemicals was shown by <em>A. capillaris,</em> and the smallest by <em>F. arundinacea.</em></p>.

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.).

The turfgrass establishment is an important criterion for the choice of turfgrass species. The faster a lawn is established the more benefits it has to offer for landscapers. The objective of this work is to study the growth speed and development of six species. Four of them are cool-season ones (temperate): Lolium perenne, Festuca arundinacea, Agrostis stolonifera and Poa pratensis while the other two are warm-season ones (tropical): Pennisetum clandestinum and Cynodon dactylon. The species are seeded in two distinct periods: spring and autumn and are studied under the climatic conditions of the eastern region of Morocco which is characterized by a semi-arid Mediterranean climate with continental tendency known for its severe cold in winter. The coverage rate is the parameter considered in order to determine the duration of establishment for each species. The study was conducted in the experimental station of the Faculty of Sciences of Oujda. The results show that the establishment pace differs depending on the season and the nature of the species. Autumn is the suitable season for temperate species, while tropical species have shown a faster growth in spring. Lolium perenne and Cynodon dactylon are the fastest species to establish as they need a maximum of 30 days after the seedlings’ development. Poa pratensis is the last species to cover the total area seeded within 50 and 60 days during the two season’s spring and autumn respectively
