Strong benefits of species diversity have been demonstrated in mixed cropping on rangelands. In order to determine the best composition of mixed cropping of alfalfa (Medicago sativa) with three cool season grass species (Agropyron elongatum, Agropyron desertorum and Festuca arundinacea), on yield and quality traits, an experiment was conducted during two years (2009 and 2010) in Bojnourd, Iran....

Abstract Aims Root tensile tests are often rejected if failure location is outside the middle section of samples. This study aims to identify where and why occurs along a root axis, hence revisit current approaches test-validity. Methods Roots from Festuca arundinacea; Lolium multiflorum; perenne were sampled field-grown plants. tested using universal testing machine. samples randomly allocated...

There are several very accurate methods to determine leaf angles in closed canopies. However, these are generally very time-consuming or require special equipment. Average canopy leaf angles were derived from simple height and blade length measurements. An exponential relationship between the height/length ratio and the average blade leaf angle was used. The method was tested for two grass spec...

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...

Bu çalışma, Orta Karadeniz Bölgesi doğal florasından toplanan domuz ayrığı (Dactylis glomerata ssp.), kamışsı yumak (Festuca arundinaceae ssp.) ve ak üçgül (Trifolium repens popülasyonlarının çekirdek DNA içeriklerinin flow sitometri yöntemiyle belirlenmesi ploidi analizi ile tür teşhisinde kullanılması amacıyla yürütülmüştür. Proje kapsamında üçgülden mera tipi 80, ayrığından ot 80 yumaktan ot...
