Ergovaline levels in cultivars of Festuca arundinacea

An evaluation of callus induction and plant regeneration in twenty-®ve turf-type tall fescue (Festuca arundinacea Schreb.) cultivars

In order to investigate the genetic variation in tissue culture response and to ®nd the cultivars with high regeneration ability for genetic transformation, twenty®ve turf-type tall fescue (Festuca arundinacea Schreb.) cultivars, including many elite ones released recently, were evaluated for their callus induction and plant regeneration responses. Callus induction was initiated from mature see...

Web Uygulamalarında Dolaşım ve Erişim Kontrolü Hatalarının Tespiti ve Yeniden Canlandırılması

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...

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...
