AMPHIPOLYPLOIDY IN THE HYBRID FESTUCA ARUNDINACEA × GIGANTEA

Ergovaline levels in cultivars of Festuca arundinacea

Control of Johnsongrass (Sorghum halepense) in tall fescue (Festuca arundinacea) stands

Johnsongrass is a nonnative invasive species introduced as a forage crop from the Mediterranean region (Miller and Miller 1999). This perennial species has become naturalized and is found in 47 of the 50 United States (Alaska, Minnesota, and Maine being the exceptions) (USDA 2004). Johnsongrass has become problematic along roadsides in Kentucky due to its aggressive and prolific nature and rapi...

Bacterial community evaluation during establishment of tall fescue (Festuca arundinacea) in soil contaminated with pyrene.

A greenhouse study was conducted to monitor microbial community dynamics related to contaminant concentration and plant growth during the phytoremediation of pyrene. Soil microbial communities in both bulk and rhizosphere soils were assessed using a polymerase chain reaction--denaturing gradient gel electrophoresis (PCR-DGGE). However, no correlation between pyrene concentration and bacterial c...

Variation and genetic structure of Tunisian Festuca arundinacea populations based on inter-simple sequence repeat pattern.

Tunisian tall fescue (Festuca arundinacea Schreb.) is an important grass for forages or soil conservation, particularly in marginal sites. Inter-simple sequence repeats were used to estimate genetic diversity within and among 8 natural populations and 1 cultivar from Northern Tunisia. A total of 181 polymorphic inter-simple sequence repeat markers were generated using 7 primers. Shannon's index...

Lead Accumulation by Tall Fescue (Festuca arundinacea Schreb.) Grown on a Lead-Contaminated Soil

Phytoextraction is gaining acceptance as a cost-effective and environmentally friendly phytoremediation strategy for reducing toxic metal levels from contaminated soils. Cognizant of the potential of this phytoremediation technique as an alternative to expensive engineering-based remediation technologies, experiments were conducted to evaluate the suitability of some plants as phytoextraction s...
