“…In our study, nitrogen fertilization influenced the better use of water by plants. An increase in WUE in response to nitrogen fertilization of festulolium variety plants has been observed previously by Olszewska (2008a).…”

“…According to Shangguan et al (2000), a nitrogen content in leaves is in close correlation with the content of Rubisco, which is the most common enzyme in the leaves of C 3 plants, and plays an important role in CO 2 assimilation. Research conducted by Olszewska (2008a) on festulolium (Festulolium braunii) and Grygierzec (2012) on perennial rye grass (Lolium perenne) showed that the highest rate of plant photosynthesis was recorded at a medium dose of nitrogen (50-60 kg ha -1 per year) and the intensity in this process was reduced in plants fertilized with a double N dose (100-120 kg ha -1 per year). According to Chen et al (2005), varying N addition rates do not alter the gas-exchange characteristics of grasses (Leymus chinensis and Stipa grandis) including the P N , E, g s , and C i .…”

“…Nutrients availability affects significantly the photochemical part of photosynthesis (Kalaji et al 2014). The effects of nitrogen accessibility on physiological processes of plants have been well documented in numerous studies (Olszewska 2008a(Olszewska , Živčák et al 2014. Nitrogen is also known to play an important role in coordination between photosynthesis process and supplying plant organ acceptors with photoassimilates (Starck 2010).…”

The response of some photosynthetic parameters (CO 2 assimilation, transpiration rate, stomatal conductance, intercellular CO 2 concentration, water-use efficiency, and chlorophyll content), shoot development, and the morphological features of the root system to differentiated conditions of nitrogen supply was tested in festulolium (Festulolium braunii K. Richert A. Camus) varieties (Felopa and Sulino). Nitrogen fertilization with no nitrogen added [0 g(N)], single dosage [0.23 g(N)], and double dosage [0.46 g(N)] per pot and per year was applied. Lack of nitrogen resulted in formation of longer and finer roots and lowered chlorophyll content, CO 2 assimilation, and water-use efficiency, resulting in lower dry matter accumulation. Application of both dosages of nitrogen resulted in improved aboveground features, while root features were enhanced without nitrogen fertilization. Dependence between physiological parameters and morphological traits was significant and positively correlated in the case of the aboveground parts of plants and negatively correlated to the belowground parts.

“…The cultivation of legume-grass mixtures, which are a valuable source of protein in animal nutrition and enable the production of fodder under conditions of low N fertilization, is particularly important under sustainable farming. A major role in this respect is attributed to T. repens, which gives a high yield in the mixture with Festulolium braunii giving high quality fodder (Olszewska 2008). F. braunii is an intergeneric hybrid formed from Festuca pratensis and Lolium multiflorum.…”

Water deficit is one of the main environmental factors, and the recognition of plant response to drought stress seems to be crucial for the yield improvement of the important crops. The aim of the study was to investigate the effect of prolonged drought stress on dry matter yield, gas exchange parameters, and relative chlorophyll content in the leaves of Festulolium braunii and Trifolium repens grown in pure stands and in mixture. In the pot experiment, different levels of soil moisture (well-watered conditions and drought stress) and of cultivation method (pure stand and mixture) have been applied. The study has shown that all measured parameters were affected by drought stress. Dry mass yield, net photosynthetic rate (PN), transpiration rate (E), and stomatal conductance were significantly lower under drought stress than under well-watered conditions in all treatment types. T. repens showed the strongest response to stress, whereas F. braunii the weakest when both those species were grown in the pure stand. Under drought conditions, the yield of the mixture was similar to that of F. braunii cultivated in the pure stand, and significantly higher than that of T. repens cultivated in the pure stand. It was also found that under the stress, PN and E of both species in the the mixture was higher than in the pure stand. The highest water use efficiency was observed in F. braunii grown in the mixture. Our research shows, that in regions with limited rainfall, T. repens is more useful for growing in a mixture with F. braunii, than in the pure stand.

“…Festulolium braunii cultivars, obtained from crossing autotetraploid forms of meadow fescue and Italian ryegrass in combinations Festuca pratensis (2n=4x=28) × Lolium multiflorum (2n=4x=28), are valuable components of seed mixtures designed for ley farming, and can even be used for renovation of permanent grassland (Kryszak et al 2002, Opitz von Boberfeld and Banzhaf 2006, Wolski et al 2006, Olszewska 2008, Ghesquière et al 2010, Černoch and Groenbaek 2015, Wyss and Frick 2019. The high nutritional value and high dry matter yield potential of these cultivars provide an opportunity to reduce the costs of milk and beef production.…”

The aim of this study was to evaluate the tensile strength of the rachilla in spikelets of Polish cultivars of Festulolium braunii (K. Rich.) A. Camus during seed development and maturation. The investigations were carried out in 2009-2010 at the Plant Breeding, Szelejewo, Poland. The inflorescences were randomly harvested in June-July from plant collection in maintenance breeding of three Polish cultivars (Agula, Felopa, and Sulino). Using a specifically developed testing machine, tensile strength of the rachilla of individual spikelets were determined. Regardless of the F. braunii cultivar, the tensile strength of the rachilla decreased through consecutive growth stages. The highest tensile strength of the rachilla was observed during the phase of kernel watery ripe stage (BBCH 71)-it ranged from 510.1 mN in 'Agula' to 592.0 mN in 'Felopa'. At the fully ripe phase (BBCH 89), the value of this trait ranged from 19.2 mN in 'Agula' to 45.0 mN in 'Felopa'. It was also observed that in all tested cultivars of F. braunii, the spikelets located in the lower part of the spike were characterised by the highest tensile strength of the rachilla, whereas those in the upper part were characterised by the lowest values of this trait. This means that the caryopses in the spikelets located at the lower part of the inflorescence were less susceptible to shedding. Seed shedding the Polish F. braunii cultivars, especially 'Agula' and 'Sulino', may start as early dough and soft dough phases. By contrast, seed shedding 'Felopa' is moved to the later phases of seed maturation.
