The genus Dactylis, an important forage crop, has a wide geographical distribution in temperate regions. While this genus is thought to include a single species, Dactylis glomerata, this species encompasses many subspecies whose relationships have not been fully characterized. In this study, the genetic diversity and phylogenetic relationships of nine representative Dactylis subspecies were exa...

Morphological studies and phylogenetic analysis based on the ITS sequence data showed that there is considerable differences within the Puccinia striiformis complex on members of Triticeae(Triticum and Hordeum), Dactylis glomerata and Poa pratensis. Based on the above molecular and morphological data, we suggest dividing P. striiformis as follows: - P. striiformis s. str. mainly on Triticeae. -...

Evaluation of Genetic Variation and Simultaneous Selection for Seed Forage Yield in Selected Genotypes Dactylis glomerata Bromus inermis

The objective of the study was to evaluate the effect of the biostimulant Kelpak on true protein and simple sugar contents of Dactylis glomerata and Festulolium braunii at different nitrogen rates. A field experiment was set up as a randomised sub-block design (split-split-plot) with three replicates. The following factors were ha, pure-sown grass species and cultivars (monoculture). Protein co...

BACKGROUND AND AIMS Current agricultural practices are based on growing monocultures or binary mixtures over large areas, with a resultant impoverishing effect on biodiversity at several trophic levels. The effects of increasing the biodiversity of a sward mixture on dry matter yield and unsown species invasion were studied. METHODS A field experiment involving four grassland species [two gra...

Since grass will likely be a dominant feedstock for on-farm anaerobic digestion in Northwest Europe, changes in the chemical composition of five common grass species with advancing harvest date in the primary growth were investigated and related to specific CH(4) yields. The increase in fibre components with advancing harvest date had a negative impact on the specific CH(4) yield (253 and 225 N...

The effect of traffic on the content of lead and cadmium in grass morphological parts-leaves, shoots, and inflorescences-was studied. The samples were taken on a part of the European route E30 (Siedlce by road). The following plants were tested: Dactylis glomerata, Arrhenatherum elatius, and Alopecurus pratensis. During the flowering of grasses, the plant material was collected at distances of ...

In this study, we investigated the impact of different land use intensities (LUI) on the root-associated microbiome of Dactylis glomerata (orchardgrass). For this purpose, eight sampling sites with different land use intensity levels but comparable soil properties were selected in the southwest of Germany. Experimental plots covered land use levels from natural grassland up to intensively manag...

Seed germination generally presents a peak in the next growing season after a fire. Among other factors associated with fire are the increase of soil nitrogen and changes in the pH of the soil. In this study, we addressed the question, whether or not the germination response of eight species is linked with the increase in pH and nitrogenous compounds in the germination media? We assessed the se...
