according to high importance of sodding for fast creating green beds in all seasons, this experiment carried out with aimidentifying suitable substrate and covering plant including two lawn genus and dichondra with blend seed. the trial carried out as factorial experiment with three factors based on complete block design in three replications. experimental factors consisted of planting networks...

Calcium (Ca+) may be involved in plant tolerance to heat stress by regulating antioxidant metabolism or/and water relations. This study was designed to examine whether external Ca2+ treatment would improve heat tolerance in two C3, cool-season grass species, tall fescue (Festuca arundinacea L.) and Kentucky bluegrass (Poa pratensis L.), and to determine the physiological mechanisms of Ca2+ effe...

Pigments, proteins and enzyme activity related to chlorophyll catabolism were analysed in senescing leaves of wild-type (WT) Lolium temulentum and compared with those of an introgression line carrying a mutant gene from stay-green (SG) Festuca pratensis. During senescence of WT leaves chlorophylls a and b were continuously catabolised to colourless products and no other derivatives were observe...

Adaptation to temperate environments is common in the grass subfamily Pooideae, suggesting an ancestral origin of cold climate adaptation. Here, we investigated substitution rates of genes involved in low-temperature-induced (LTI) stress responses to test the hypothesis that adaptive molecular evolution of LTI pathway genes was important for Pooideae evolution. Substitution rates and signatures...

Some members of the familyClavicipitaceae are endophytic and have mutualistic relationship with the plant family Poaceae. Their relationship is beneficial for both host and fungus. In the present investigation, endophytic fungi were isolated from seed and leaf sheath of hosts Festuca arundinacea, F. ovina, F. pratensis, Bromus tomentellus, Melica persica and Lolium prenne. Morphological charact...

The paper presents data on the indicators of livestock production, number farm animals and poultry in Tyumen region. characteristics significance near-village forage lands are given. studied assigned to forest-steppe lowland latitudinal-zonal area Kurgan province contain valuable species herbs: Calamagrostis epigejos, Bromopsis inermis, Festuca pratensis, Vicia villosa Roth, Trifolium rubens L....

We examined how elevated atmospheric [CO2] and higher rate of nitrogen (N) input may influence grasshopper growth by changing food plant quality and how such effects may be modified by species diversity of the plant community. We reared grasshopper nymphs (Melanoplus femurrubrum) on Poa pratensis from field-grown monocultures or polycultures (16 species) that were subjected to either ambient or...
