This study was conducted to investigate effects of different levels ammonium nitrate (33% N) dose (0, 50 and 100 g m-2) on morphological quality traits 3 commonly cultivated turfgrass species (Lolium perenne ‘TOPGUN’, Festuca rubra ‘SERGEİ’ Poa pratensis ‘AVALANCHE’) which are widely preferred in grass mixtures prepared for green areas Çanakkale (Turkey). Fertilization treatments had positive p...

A pot experiment was conducted to investigate the solubility and redox species of antimony (Sb) in a relocated shooting range soil and its uptake by Lolium perenne L. and Holcus lanatus L. under different water regimes. After 1-week waterlogging, the total Sb concentration in soil solution decreased from ∼110 μg L(-1) to <20 μg L(-1), and slowly increased over the following 4 weeks, with the di...

Substitution of a species or cultivar with higher uptake of an element by one with lower uptake has been proposed as a remediation strategy following accidental releases of radioactivity. However, despite the importance of pasture systems for radiological dose, species/cultivar substitution has not been thoroughly investigated for forage grasses. 397 cultivars from four forage grass species; hy...

Within the Oltenia surface mining region of Romania, 14,890 ha have been disturbed and only 1,002 ha have been reclaimed. The majority of this disturbance has involved agricultural land (12,208 ha), of which only a small amount has been reclaimed (552 ha). Forest land disturbed by surface mining in this region amounted to 2,682 ha, of which only 450 ha have been reclaimed. Therefore, huge land ...

perenial rygrass (lolium perenne cv. “numan”)belongs to poaceae family as an important lawn in landscape design. the objective of this research was to evaluate effects of different concentrations of salicylic acid to enhance the growth and biochemical characteristics of lolium perenne l. under drought conditions. factorial experimental design was arranged in a completely randomized block design...

The main storage compounds in Lolium perenne are fructans with prevailing β(2-6) linkages. A cDNA library of L. perenne was screened using Poa secunda sucrose:fructan 6-fructosyltransferase (6-SFT) as a probe. A full-length Lp6-SFT clone was isolated as shown by heterologous expression in Pichia pastoris. High levels of Lp6-SFT transcription were found in the growth zone of elongating leaves an...

BACKGROUND AND AIMS Growth of grass species in temperate-humid regions is restricted by low temperatures. This study analyses the origin (intrinsic or size-mediated) and mechanisms (activity of individual meristems vs. number of active meristems) of differences between Bromus stamineus and Lolium perenne in the response of leaf elongation to moderately low temperatures. METHODS Field experime...
