هدف از تحقیق حاضر شناسایی و ارزیابی گونههای گیاهی مقاوم به فلزات سنگین در منطقه نفتخیز پازنان گچساران بود. از مرکز آلودگی، سه محدوده 0 تا 500 متر، 500 تا 1000 متر و 1000 متر تا 1500 انتخاب گردید. در هر محدوده، 30 پلات 2× 2 مستقر و ویژگیهای پوشش گیاهی برداشت شد و 15 نمونه خاک، از منطقه جمعآوری شد. برای اندازهگیری فلزات سنگین سرب و نیکل از دستگاه ICP-OES استفاده شد. شاخصهای TF، BCF و BAC ج...
Late summer and autumn application of nitrogen (N) to bermudagrass (Cynodon spp.) in the transition zone has been associated with enhanced turfgrass color but thought increase potential for winter injury. Eleven N sources were applied late early provide a total annual level 98 kg ha−1 Olathe, KS evaluate fall spring green coverage ‘Riviera’ [Cynodon dactylon (L.) Pers.]. Treatments included exp...
This research aimed to investigate plant species diversity and spatial distribution of five dominant species i.e. Phragmites australis, Tamarix meyeri, Aeluropus littoralis, Aeluropus lagopoides and Cynodon dactylon in Hamoon international wetlands in 2015. To this end, a randomize-systematic sampling method was used according to w pattern by four strip transect at 5000 m2 at each station. The ...
BACKGROUND: Urinary oxalate and citrate are the keyfactors in caox urolithiasis of cats and Gamma GlutamylTransferase is a good test for assessment of kidney damage.Favorable effects of Cynodon dactylon on calcium oxalate stoneformation have recently been proved in rats. OBJECTIVES: Thepresent study was designed to investigate the alteration ofurinary oxalate, citrate, and GGT after administrat...
Salinity is one of the most important ecological stresses which have undesirable effects on seed germination. This study was carried out to evaluate the germination of three species of lawn (Poa pratensis, Lolium perenne, Cynodon dactylon) seeds under salinity stress. The effect of different treatments (Gibberellins 50 mgl-1, 2% CaCl2 and hydroprimig in 24 hours) was evaluated on total germinat...
Two experiments were conducted to compare the effects of a progesterone-estradiol implant (PEI) with no implant (NI) and 20 g of copper oxide needles (CuON) with no CuON on grazing, subsequent feedlot performance, and selected serum constituents of steers. In Exp. 1, 114 Limousin crossbred yearling steers (317 kg average initial BW) were stocked continuously on Acremonium coenophialum-infected ...
The implementation of cover crops in vineyards is an environment-friendly soil management technique that has several advantages, including weed suppression. effectiveness the depends on characteristics both community and crop species. objectives this study were to evaluate dynamics Cynodon dactylon patches rest composition under five different (four grasses one dicotyledonous species) a commerc...
The subtribe Eleusininae Dumort. (Poaceae: Chlorid oideae: Cynodonteae) is a morphologically diverse group, characterized by having racemose inflorescences (with a few exceptions) and contains about 212 species in 31 genera found primarily in low latitudes in Africa, Asia, Australia, and the Americas. Ten of the genera are currently monotypic (Apochiton C.E.Hubb., Austrochloris Lazarides, Dakn...
A mixture of common Southern Piedmont (USA) grassland species (Lolium arundinacea, Paspalum dilatatum, Cynodon dactylon and Trifolium repens) was exposed to O(3) [ambient (non-filtered; NF) and twice-ambient (2X) concentrations] and fed to individually caged New Zealand white rabbits (Oryctolagus cuniculus) in a digestibility experiment. Forages and feed refusals were analyzed for concentration...
