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:
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.

Opis:
The aim of this study is to show the role of Lolium perenne L. in the carpet plant communities which develop on trampled places such as: roadsides, wastelands, playgrounds, sport fields, lawns, railway areas in the Upper Silesian Industrial District. In order to recognise plant communities there were made 120 phytosociological relevés. There were recognized 5 plant communities which are built mainly by annuals from Polygono-Poëtea class (Polygonetum calcati, Sagino-Bryetum, Puccinellio-Chenopodietum, Poëtum annuae, Matricario-Polygonetum) and 5 in structure of which the main role play hemicryptophytes from Molinio-Arrhenatheretea class, Trifolio-Plantaginetalia order, Cynosurion (Lolio-Plantaginetum, Juncetum macri), and Agropyro-Rumicion (Potentilletum anserinae, Potentilletum reptantis, Odontites serotine community) alliances. In carpet plant communities occur from 3 to 25 grasses, and their participation in the floristic list range from 12% to 32%. Lolium perenne was recorded in almost each plant community with the exception of Sagino-Bryetum. The highest percentage participation in the plant cover it has in Odontites serotina community and Lolio-Plantaginetum phytocoenoses. In the lalter one it has it ecological optimum.

Opis:
Seed production in warmian-mazurian voivodeship has signify position in Poland and considering that favourable nature terms and relatively satisfied yields this position seems to be solid. The main species in grass seed production on this area is perennial ryegrass, particularly ‘Nadmorski’ (‘Naki’) cultivar. Increasing number of plantation is a positive fact, as also area stabilization of gazon cultivars, particularly ‘Stadion’ cultivar. Seed production of perennial ryegrass is concentrated in Iława, Ostróda and Nowe Miasto districts - above 80% seed plantation area. This is zone of Rolimpex S.A. activity – the biggest contracting party of seed grasses, particularly perennial ryegrass in voivodeship.
