Presence of petroleum contaminants in soil may be toxic to human and organisms and act as a source of ground water contamination hence, remediation of these compounds from environment is vital. In this study, first the feasibility of remediation of two petroleum-contaminated soil samples around Tehran Oil Refinery (oil refinery landfill and agricultural soils) was assessed using landfarming tec...

Experiment on estimation of qualitative changes in populations of meadow fescue (Festuca pratensis Huds.) after seed storage in different conditions were taken. Phenotypical traits for plants derived from seeds stored during 54 months in two different kind of storage conditions were compared. Storage of meadow fescue seed during 54 months in unfavourable conditions resulted in decrease of initi...

The effects of seed source and seed size on germination and field performance were studied in five grasses. Greater seed weights were associated with better germination in Yorkshire fog, cocksfoot and timothy but not significantly so for Chewings fescue and browntop. In cocksfoot, Chewings fescue and timothy, higher seed weights were found in samples collected at altitudes above those generally...

The pasture and animal productivity of established high producing pastures in the Waikato has been compared with newly sown pastures based on recently released herbage cultivars. The established pastures were a mixture of Nui perennial ryegrass, Paspalum dilatatum and Htiia white clover. The new cultivars tested were Ellett perennial ryegrass, Wana cocksfoot and Roa tall fescue, each sown with ...

Phytoremediation efficiency mainly depends upon mechanisms in the uptake and translocation of soil contaminants. Cadmium (Cd) distribution and translocation in roots and shoots of tall fescue (Festuca arundinacea) and Kentucky bluegrass (Poa pratensis) were observed using fluorescence spectroscopy with a laser confocal scanning microscope. No difference in root Cd accumulations was detected bet...

To prevent the 7 to 11 million metric tons of waste foundry sand (WFS) produced annually in the USA from entering landfills, current research is focused on the reuse of WFSs as soil amendments. The effects of different WFS-containing amendments on turfgrass growth and nutrient content were tested by planting perennial ryegrass (Lolium perenne L.) and tall fescue (Schedonorus phoenix (Scop.) Hol...

In plant species, control of flowering time is an important factor for adaptation to local natural environments. The Vrn1 , CO , FT1 and CK2α genes are key components in the flowering-specific signaling pathway of grass species. Meadow fescue is an agronomically important forage grass species, which is naturally distributed across Europe and Western Asia. In this study, meadow fescue flowering-...

Previous research has implicated an endophytic fungus as being associated with fescue toxicity (summer syndrome) in cattle grazing Kentucky 31 tall fescue (Festuca arundinacea Schreb.) pastures. Hay and seed were harvested from Kentucky 31 pastures known to be either fungus-free or heavily infested with an endophytic fungus identified as Acremonium coenophialum Morgan-Jones and Gams. Four diets...

Forty steers and 40 heifers were allocated by gender and previous treatment to eight 12-acre Kentucky-31 tall fescue pastures. Each pasture was assigned to one of four supplement treatments to test the ability of either supplemental energy or two levels of supplemental escape protein to correct a possible ruminal imbalance of protein and energy found in high quality forages. Supplementation tre...
