Lolium perenne
Opis:
This article reviews the selected problems concerning the taxonomy, karyology, origin, and distribution of the genus Lolium, and especially of L. perenne. The genus consists of eight diploid (2n = 14) species. Four are cross-pollinated (e.g. L. perenne, L. multiflorum), and four are self-pollinated (e.g. L. temulentum, L. remotum). From the taxonomical point of view the first group is often classified as the section Lolium and the second as the section Craepalia. They all originate from the Mediterranean region, most of them are widely distributed in Eurasia and introduced in Africa, Americas, and Australia. In Poland occur: L. perenne, L. multiflorum, L. temulentum, L. rigidum as well as L. remotum and L. subulatum, which occurrence seems to be doubtful. L. perenne is morphologically differentiated and sometimes it is divided (on the basis of inflorescence characters) into several infraspecific taxa, usually varieties. It cross easily with L. multiforum, L. rigidum, other species of the genus and even with some representatives of Festuca. This interfertility suggests that there is no barrier to free gene-exchange between them. The species originate probably from the Mediterranean region, however its natural geographical distribution is rather obscure (at present it is impossible to distinguish its natural and synanthropic localities). In Poland it occurs in the whole territory of the country. L. perenne belongs to the apophytes for which we did not succeed in showing the community of origin. Presently, it grows in ruderal, segetal and seminatural communities of the class Molinio-Arrhenatheretea. Undoubtedly, L. perenne together with other species of the genus constitute an important group of grasses of great interest to botanists as well as to plant breeders and agriculturists. For this reason further fundamental and complementary studies should be carried out.

Opis:
The effectiveness of perennial ryegrass plantations, and hence their profitability, depends, to a considerable extent, on the specificity of the reproduced cultivar. The most appropriate strategy for maintaining high seed yields of new grass cultivars, apart from the improvement of their fodder and lawn aspects, is to seek to obtain the highest seed yield calculated per one generative shoot. In order to increase the efficiency of perennial ryegrass seed plantation it is necessary, apart from the improvement of the seeding aspect of a given cultivar by way of breeding work, also to improve technology of their cultivation. This target can be reached by optimization of agrotechnical factors stimulating biological reproductive potentials of cultivars. Results of own studies indicate that there is an optimal state of nitrogen concentration of perennial ryegrass plants in successive growth stages, which guarantees obtaining the highest seed yields on plantations. In the case of ‘Maja’ cultivar, the content of nitrogen in leaf blades at the beginning of vegetation should amount to 47 g kg⁻¹ DM and at the car initiation - 51 g kg⁻¹ DM. in the case of ‘Anna’ the optimal concentration of nitrogen in leaf blades were 54 and 57 g kg⁻¹ DM, respectively. Another very important factor is the determination of the optimal time and method of harvest as they affect the level of losses of the produced seed yield. The optimal time of seed harvest on perennial ryegrass plantations is the drop of sugars in kernels to the level of 5% DM. The increase of yields from seed plantations of Lolium perenne is a strategic matter for Polish grass seed production, which constitutes an important segment of the domestic seed industry.

Opis:
The aim of studies was to evaluate the performance value of domestic cultivars of Lolium perenne on a base of area sodding uniformity under conditions of different number of cuttings during vegetation period. Studies were performed in 1996-2000. Experiments were set on light mineral soil by means of randomized block in four replications. The soil was characterized with neutral reaction (pHKCI 6.9). Contents of available phosphorus, potassium and magnesium forms were: 82, 166 and 52 mg kg⁻¹, respectively. Following cultivars of L. perenne were subjected to studies: ‘Gazon’, ‘Nira’, ‘Niga’, ‘Inka’ and ‘Stadion’. Two variants of cutting frequency were applied in experiments. In the first variant A (intensive), number of cuts depending on study year was 23-26 and mineral fertilization was applied at rates: N - 240, P - 39.2, K - 121.2 kg ha⁻¹. In variant B (extensive), there were 6-10 cuts and mineral fertilization was applied at rates: N - 60, P - 17.5, K - 40 kg ha⁻¹. During vegetation in years of full performance, sodding assessment was done according to 1-9 grade COBORU scale. Study results revealed that sodding of L. perenne cultivars was variable both in years and in particular terms of observation during vegetation period.

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.

Lolium perenne
Opis:
On the basis of 4000 phytosociological surveys taken using the Braun-Blanquet method, it was found that Lolium perenne occurs in meadow-pasture communities of 5 phytosociological classes, namely: Molinio-Arrhenatheretea, Phragmitetea, Koelerio glaucae-Corynephoretea canescentic, Scheuchzerio-Caricetea fuscae and Agropyretea intermedio-repentis. The highest proportion of this species occurred in Molinio-Arrhenatheretea, which is associated with site conditions and the level of utilisation. The share of Lolium perenne in the identified communities showed variations between river valleys. It was found to occur most frequently and numerously in valleys of such smaller rivers as: the Barycz, the Rów Ostroroski, the Mogilnica, the Sama Szamotulska. The development of degradation forms of communities in the Molinio-Arrhenatheretea class containing Lolium perenne was associated mainly with the impact of the anthropogenic factor, in particular with limited fertilisation and grazing (sometimes with its complete abandonment). In communities of the remaining classes, the factor limiting the share of Lolium perenne was site conditions, primarily poor soil fertility and different ways of utilisation. In areas situated at foothills and seaside, Lolium perenne occurs less frequently and at a lower share in meadow-pasture communities, which can be associated with utilisation intensity and non-forage functions.
