Mature perennial ryegrass plants in pastures persist through the asexual reproduction of the tiller. Leaves are initiated from the flanks of the tiller stem apex. Generally, two leaves arc growing on a tiller at any one time. New tiller buds may arise from the axils of mature leaves depending on environmental conditions. Flowering results from a physiological change at the stem apex, which then...

This study was conducted to investigate effects of different levels ammonium nitrate (33% N) dose (0, 50 and 100 g m-2) on morphological quality traits 3 commonly cultivated turfgrass species (Lolium perenne ‘TOPGUN’, Festuca rubra ‘SERGEİ’ Poa pratensis ‘AVALANCHE’) which are widely preferred in grass mixtures prepared for green areas Çanakkale (Turkey). Fertilization treatments had positive p...

Fires will become an increasingly frequent perturbation even under the conditions of mild climate zone and interfere with agricultural landscape. Fire is a natural phenomenon, depending on ecosystems, vegetation may develop contribute to occurrence spread fire. Vegetation sour cherry orchard located in climatically dry South Moravian Region, Czech Republic (CR), was evaluated. assessment perfor...

Pooideae species. While for several species the most important allergens (group 1 and group 5) have been identified, other allergens have either not been identified or sequence data are still missing. We have used mass spectrometry (MS) together with genetic and immunological methods to identify allergens in various grass pollen extracts. Methods: Pollen extracts of 6 different grass species (P...

In meadow fescue (Festuca pratensis Huds.), a perennial fodder grass plant characterized by high quality and yield potential, seed shattering makes production difficult. The objective of the research was to compare two subpopulations, differing in tendency shattering, with respect their variability beginning heading flowering stages, morphological traits (plant height panicle length), changes o...
