SCANTURF is a joint Nordic programme for turfgrass variety testing, set up in 2005 and funded by entrance fees only. It replaced simplified the former government-funded national evaluation programmes Finland, Sweden, Denmark Norway. The includes testing of all cool-season grasses on lawn/fairways at 15–20 mm mowing height (“lawn trials”) optional Poa pratensis L. Lolium perenne simulated footba...

There is a need to identify turfgrass species and mixtures for golf course fairways that can be managed sustainably with reduced fertility, pesticides, irrigation. The current study evaluated Agrostis stolonifera L. (creeping bentgrass [AST]), capillaris (colonial [ACP]), canina (velvet [ACN]), Festuca rubra ssp. commutata Gaudin (Chewings fescue [FRC]), brevipila Tracey (hard [FBP]), littorali...

abstract in order to evaluate chemical control of bermudagrass (cynodon dactylon (l.) pers.) on mixture turf: (lolium perenne 20%,poa pratensis.20%,festuca arundinacea 20% and festuca rubra commutata 40%), an experiment was conducted during 2006 in tehran, using randomized complete block design with 4 replications and 11 treatments. treatments were diclpfop methyl at 900 and 1080 g a.i. ha-1, f...

The rangeland in the Khangai mountain region in Mongolia has degraded for the last decades mainly because of overgrazing and climate change. Livestock production is important part of the economy and is based on natural rangeland. In this research we seek to elucidate the influence of five years (2004-2009) of protection from grazing on vegetation cover of different degradation levels of Fes...

We experimentally tested the effect of food quality (phosphorus [P] : carbon [C] ratio) on the response of antioxidant enzymes to ultraviolet radiation (UVR) in Daphnia commutata fed with Chlamydomonas reinhardtii. Algal cultures were grown at different concentrations of phosphorus and light intensities, resulting in significant differences in the P : C ratios (mmol P?[mmol C]21; 6.05, 1.70, an...

Question : Rich fens of the Sphagno warnstorfii-Tomentypnion nitentis alliance require a specific combination base richness and climate to occur. Their rarity at southeastern margins their European range has previously prevented rigorous vegetation classification. We asked how many associations may be delimited here whether some them are restricted high Balkan Mountains showing endemicity. Stud...

Diatoms are one of the major algal groups having an important role in aquatic systems which they constitute main primary production with dinoflagellates coastal regions, and can contribute to photosynthesis at great rates. There had been intense effort reveal diatom community light microscopy (LM) scanning electron (SEM), on other hand, DNA barcoding techniques interest understand microbiome la...

Cool-season grasses are intensively cultivated for seed production in western Oregon, where stem rust is the most damaging disease on several species, including perennial ryegrass (Lolium perenne), annual ryegrass (L. multiflorum), and tall fescue (Festuca arundinacea). Stem rust also occurs on seed crops of orchard grass (Dactylis glomerata) and red fescue (F. rubra) in the region. The causal ...

The behavior of turfgrass-infesting scarab grubs in response to soil physical properties may affect the stress that each species exerts on turfgrass and the efficacy of control tactics. To gain a more realistic picture of the events that occur within the soil matrix, we have developed a nondestructive X-ray technique to study soil insect movement and behavior in simulated and natural soil block...
