<\/b>The reproductive potential of Dactylis glomerata<\/i> varieties dependingon row spacing during four-years utilization<\/span><\/p>\r\nAbstract.<\/strong> Dactylis glomerata<\/i> varieties were tested in a seed cultivation established in a pure, late spring sowing against the background of two row spacing (50 and 70 cm) during 4-years investigations. The field experiment in central Poland was established in a split-plot configuration on 3 m2<\/sup> plots with four replications. Two factors were considered: variety (six varieties) and row spacing (50 and 70 cm). There were analyzed: formation of generative shoots (number) and seed yield. The seed yield changed depending on variety and year of utilization. The highest seed yields were obtained in the second and the third year. It was found that the seed yield and the number of generative shoots depended on cultivar and row spacing. Significant positive correlation coefficients were obtained between seed yield and the number of generative shoots of Dactylis glomerata<\/i> varieties at the investigated row spacings.<\/span>

<\/span>Test flights of meadow communites by Apidae<\/em> insects<\/span><\/p>\r\nAbstract.<\/strong> The performed investigations were carried out on meadow complexes situated in the region of Wielkopolska recognised for its long traditions of meadow management and bee-keeping. The results of our investigations and observations show that permanent meadows exhibit sufficient floristic diversity to make them attractive for Apidae<\/i>. However, flights of Apidae <\/i>to visit meadow communities in order to collect nectar vary. The attractiveness of Cirsium oleraceum <\/i>communities is evidently higher than that of Alopecurus pratensis<\/i>, while communities with Trifolium repens <\/i>and Taraxacum officinale <\/i>occupy intermediate positions. All the above-mentioned plant communities are more attractive for Apoidae <\/i>than Brassica napus cultivations<\/i>. In addition, visits paid to individual species of plant communities also vary. Apoidae <\/i>appear to favour in particular the following plant species: Vicia cracca<\/i>, Trifolium <\/i>sp., Taraxacum officinale<\/i>, Cirsium <\/i>sp., Leontodon autumnalis<\/i>, Melilotus <\/i>sp., Polygonum bistorta<\/i>, Euphrasia rostkoviana <\/i>and Lychnis flos-cuculi<\/i>. Another advantage of permanent meadows is the presence in their sward of plants which blossom during the entire period of vegetation. Therefore, if we want to enhance meadow floristic diversity, it is necessary to introduce (by oversowing) into their communities plant species which are visited by Apidae <\/i>most readily. In addition, it can be concluded on the basis of the performed experiments that the Apoidae <\/i>population in our region is very poor and is limited to the following little species: Apis mellifera<\/i>, Bombus terrestris <\/i>and B. lapidaries<\/i>, B. sylvarum<\/i>, B. pascuorum <\/i>and Halictus <\/i>sp.<\/span><\/td>\r\n

<\/b>Differentiation of rush communities of mid-field pondsin the western part of Drawskie Lakeland<\/span><\/p>\r\nAbstract.<\/strong> The objects of the research were 30 mid-field ponds situated in the western part of Drawskie Lakeland. A synthetic table shows 153 relev\u00e9s representing 12 rush associations. Totally, within the studied water ponds, 23 plant communities were distinguished, including 12 rush associations. These are: Sparganietum erecti<\/i>, Eleocharitetum palustris<\/i>, Phragmitetum australis<\/i>, Typhetum latifoliae<\/i>, Acoretum calami<\/i>, Oenantho-Rorippetum<\/i>, Cicuto-Caricetum pseudocyperi<\/i>, Iridetum pseudacori<\/i>, Caricetum acutiformis<\/i>, Caricetum gracilis<\/i>, Caricetum vesicariae <\/i>and Sparganio-Glycerietum fluitansis<\/i>. Phytosociological constancy of the species forming the structure of 12 recognized plant communities phytocoenoses: Caricetum gracilis <\/i>(75), Caricetum vesicariae <\/i>(71) and Typhetum latifoliae <\/i>(63 taxa) are floristically the richest, whereas Sparganietum erecti <\/i>(38) and Cicuto-Caricetum pseudocyperi <\/i>(41 species) are the poorest. The species characteristic of the Phragmitetea <\/i>and Molinio-Arrhenatheretea <\/i>classes are dominant among them. Rush associations of the Magnocaricion <\/i>alliance and contributions of the species from both classes are approximate. The Magnocaricion <\/i>rushes are in contact with communities of the Phragmition alliance <\/i>and with communities of moist meadows of the Molinietalia<\/i> order, hence the contribution of species to them from both the classes. In phytocoenoses of the Phragmition <\/i>alliance there are fewer species of the Molinio-Arrhenatheretea <\/i>class and slightly more species of the Potametea <\/i>class than in the communities of the Magnocaricion <\/i>alliance. The analysis of similarity of the communities was carried by the UPGMA method using Euclidean distances on the basis of phytosociological constancy of species with the application of the STATISTICA PL packet (1984\u20131985). Coefficients of similarity of the associations were calculated by means of the S\u00f6rensena method and the obtained results were shown in the Czekanowski diagram.<\/span><\/td>\r\n

<\/b><\/span>Natural values of meadow communities in valley of the Mierzawa river<\/span><\/p>\r\nAbstract.<\/strong> The aim of the research was to evaluate the meadow communities, that are accompanying the valley of Mierzawa river. The types of habitats that have been examined are the fresh and the wet meadows, that belong to various phytosociological associations, differentiated in the type of management. In explored terrain, there has been done 45 phytosociological records, during June and July in 2010 and 2011, in 16 localities, that all belong to the Niecka Nidzia\u0144ska macroregion. The Mierzawa river is a right-bank tributary of Nida, and its length is about 60 km. Altitudes above sea level in the investigated area only slightly exceed 200 m in the valley of this river. Whereas altitudes of surrounding ground reach to a little above 300 m a.s.l. In this area, there is a considerable floristic diversity, what has been assessed by a big number of plant species, genera, and botanical families, that belong to vascular plants. Natural values of that terrain were estimated according to an appropriate method, which shows that the wet meadows are more floristically diversified than the fresh meadows.<\/span> <\/span><\/td>\r\n

Germinability as well as weight of 1000 seeds were strongly affected by varietal factor and interaction of this factor with harvest date in successive years. Seeds threshed from panicles in the third degree of maturity were characterized by high germinability (84%) but the highest value of this index (87%) was estimated for seeds obtained during induced shattering, notwithstanding the lowest weight of 1000 shattered seeds (2.115 g). Inconsiderable variation of germinability of threshed seeds between applied dates of harvest in analyzed three-year period points to the possibility of harvesting at the earlier date to reduce losses in seed yield caused by shattering process.<\/span><\/td>\r\n

<\/b><\/span>Occurrence of chlorophyll and carotene dyes in forest grasses<\/span><\/p>\r\nAbstract.<\/strong> Forest grasses are poorly known with respect to their chemical composition. This remark also refers to plant dyes. Chlorophyll plays a vital part, primarily, in physiological processes, whereas carotenes, especially beta-carotene \u2013 in determining plant fodder value. Our own investigations undertook these issues with regard to 13 species of forest grasses. In the light of the obtained research results, it can be said that the occurrence of the above-mentioned dyes is a characteristic trait of individual species. Levels of dye concentrations depend on the dynamics of plant growth and development as well as site conditions, especially moisture levels. Moreover, considerable changes in chlorophyll content occurred during the vegetation season which can affect plant vitality and fodder value as well as landscape.<\/span><\/td>\r\n

Changes that have occurred in the altered area and in the undisturbed fragment were compared using multivariate methods. In the track area, reduction in abundance and decline of occurrence, of the species characteristic of psammophilic grassland, was observed, as was the decline of total floristic diversity. In their place meadow species appear and the proportion of Arrhenatherum elatius is significantly increased. The results show that, in the short term, this method of utilization has negative impact on the sandy grassland.<\/span><\/td>\r\n
