The article presents the results of morphometric study polylobed trapeziform phytoliths leaf epidermis Dactylis glomerata. relevance lies in difficulty establishing limit phytolith variability when using morphometry for paleoecological purposes. studies were performed according to recommendations International Committee Phytolith Morphometry ImageJ software and its PhytolithsBatch plugin. For f...

(1) Background: sewage sludge is a by-product of wastewater treatment, which needs to be managed appropriately, e.g., in composting processes. The application municipal composts (MSSCs) as soil amendment potential way effectively manage sludge. (2) Methods: this paper presents the results vegetation pot experiment undertaken assess suitability Dactylis glomerata L. and MSSC aided phytostabiliza...

in 1985 and has been frequently used in the USA where good summer productivity has been reported (Jung et The bimodal distribution of growth of cool-season grass species al., 1996; Volesky, 1996). Chemical analyses indicate generates an imbalance in the amount of forage available during the summer, which could be improved by using alternative forage species. that Puna chicory is a high quality ...

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...

Five grass species (Dactylis glomerata L., Phleum pratense L., Lolium perenne L., Festuca arundinacea L. and the hybrid Felina (Lolium multiflorum L. × Festuca arundinacea L.)), commonly used in roughages for ruminants, were harvested at different maturities of primary growth (n = 60) and evaluated for contents of dry matter (DM), crude protein (CP), ash, crude fat, neutral detergent fibre (NDF...

The aim of the present study is to assess the rate of protein disulphide formation and the activity of NADPH-dependent thioredoxin and glutaredoxin systems, responsible for the reverse reduction of protein and mixed protein-glutathione disulphides, in embryogenic suspension cultures of Dactylis glomerata, subjected to salt stress. Two concentrations of NaCl previously established as enhancing (...

The nutritive value of manganese and its occurrence in animal and plant tissue has received considerable attention within the last few years. The literature relating to manganese in plant tissue has been reviewed by Lindow and Peterson (^)^, who reported analyses of 84 samples representing the principal classes of human foods. In a later paper by Skinner and Peterson {12), analyses of 54 feedin...
