La festuca alta (Festuca arundinacea Schreber) es una forrajera perenne de regiones templadas importante en los sistemas producción pecuarios debido a su elevado rendimiento lugares con restricciones ambientales y edáficas. El objetivo del presente estudio fue evaluar el fenotípico diez poblaciones naturalizada ambientes semiáridos subhúmedos Argentina. Los caracteres fenotípicos altura planta,...

Large amounts of flue gas desulfurization products (FGDs) are produced when SO2 emissions are trapped in the coal burning process for generation of electricity. FGDs are normally discarded instead of being reused, and reuse on soils could be important in overall management of these products. Glasshouse experiments were conducted to determine effects of various levels of three FGDs (a FGD gypsum...

abstract many uses of landscape and important roll of ground covers aspect turfgrasses caused extensive of this plant in the cities. this study focuses on shoot responses and tolerance of native and commercial turf grasses under drought stress in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

ABSTRACT: In this study we tested whether the root biomass of mixtures composed by grass species is greater than their respective monocultures. The treatments were monocultures Arrhenatherum elatius, Festuca arundinacea, Dactylis glomerata, and a mixture them, cultivated in rich-soil environment. Root was evaluated on single evaluation per season at three soil depths (0-5, 5-10, 10-20 cm). Mixe...

Heat shock factors (Hsfs) are important regulators of stress-response in plants. However, our understanding of Hsf genes and their responses to temperature stresses in two Pooideae cool-season grasses, Festuca arundinacea, and Lolium perenne, is limited. Here we conducted comparative transcriptome analyses of plant leaves exposed to heat or cold stress for 10 h. Approximately, 30% and 25% of th...

A major benefit of supplementing non-ruminant feedstuffs with exogenous enzymes is presumed to be the degradation of plant cell-wall polysaccharides to metabolizable monosaccharide residues. In the present study, metabolic fates of (U-14C-labelled, 10 mM) glucose, galactose, mannose, xylose and arabinose were compared in the fowl, by measuring recoveries of 14C radioactivity in exhaled carbon d...
