Hybrid bermudagrasses occasionally suffer significant damage when below-normal winter conditions occur. In an attempt to enhance cold tolerance of these grasses, a study was undertaken to assess the effects of late-season nitrogen (N) fertilization and applications of the growth regulator trinexapac-ethyl (Primo) on morphology and cold tolerance of ‘Tifton 419’ hybrid bermudagrass. Nitrogen app...

Plant functional traits are thought to drive variation in primary productivity. However, there is a lack of work examining how dominant species identity affects trait-productivity relationships. The productivity of 12 pasture mixtures was determined in a 3-year field experiment. The mixtures were based on either the winter-active ryegrass (Lolium perenne) or winter-dormant tall fescue (Festuca ...

Root growth and protective enzymes of Festuca arundinacea L. and Lolium perenne L. under Cu stress were investigated in a hydroponic experiment. Cu stress significantly inhibited root growth (root elongation and dry biomass) of both turfgrasses. Malondialdehyde (MDA) content in roots of both turfgrasses markedly increased under copper stress. In F. arundinacea root, superoxide dismutase (SOD) a...

Meadows on organic soils perform an essential role as a source of fodder and biomass for energy purposes. In the case intensive meadows, it is crucial to use grass mixtures that enable obtaining high yields good quality; however, soils, species composition changes dynamically. We carried out full cultivation (ploughing) grassland restoration. The floristic meadow sward in first year (2013) was ...

Jennifer A. Rudgers*, Jennifer M. Koslow and Keith Clay Department of Biology, Indiana University, Bloomington, IN 47405, USA *Correspondence: E-mail: [email protected] Abstract Recent studies have expanded research on biodiversity by investigating whether the effects of diversity on ecosystem functioning hinge on the presence of symbiotic microorganisms. Cool-season grasses commonly harbour...

1. Flood-sensitive plant species are restricted to highly elevated sites in floodplains, but why flood-tolerant plants do not grow at higher elevations is much less clear. We test the hypothesis that a trade-off exists between flood-tolerance and selective root placement in nutrient-rich patches, a putatively important trait in the more competitive highly elevated sites. 2. Achillea ptarmica , ...

The aim of this study was to investigate the effect of molds on levels of low molecular mass thiols in grasses. For this purpose, the three grass species Lolium perenne, Festulolium pabulare and Festulolium braunii were cultivated and sampled during four months, from June to September. The same species were also grown under controlled conditions. High-performance liquid chromatography with elec...

Plants require nitrogen (N) to make proteins, nucleic acids and other biological molecules. It is widely accepted that plants absorb inorganic forms of N to fill their needs. However, recently it has become clear that plants also have the capacity to absorb organic N from soils. In this paper we describe a new kind of symbiosis involving seed-vectored rhizobacteria and grasses that is targeted ...
