There has been some transition to using low-input fine fescues on golf courses, but these species have poor traffic tolerance and divot recovery, making them impractical for playable areas courses. The objectives of this study were determine the effect plant growth regulator (PGR) trinexapac-ethyl performance fescue mixtures when managed as a course fairway identify that perform well under stre...

The genus Claviceps (Clavicipitaceae) is noted for producing ergot alkaloids that cause ergotism. yanagawaensis, a parasite of Zoysia japonica (family: Poaceae), has been isolated in Japan. Bioactivity screening showed methanol extract from rice culture C. yanagawaensis was cytotoxic to cancer cells. In our search active substances, the new secalonic acid analogues (-)-5-epi-F-7 (1) and ergochr...

Resistance to the invasion of exotic plants may sometimes result from the strong effects of a relatively small number of resident species. Understanding the mechanisms by which such species resist invasion could provide important insights for the management of invaded ecosystems. Furthermore, the individualistic responses of community members to resource availability and environmental gradients...

We tested whether the presence of plant roots would impair the uptake of ammonium ([Formula: see text]), glycine, and glutamate by microorganisms in a deciduous forest soil exposed to constant or variable moisture in a short-term (24-h) experiment. The uptake of (15)NH4 and dual labeled amino acids by the grass Festuca gigantea L. and soil microorganisms was determined in planted and unplanted ...

There is considerable evidence that both plant diversity and plant identity can influence the level of predation and predator abundance aboveground. However, how the level of predation in the soil and the abundance of predatory soil fauna are related to plant diversity and identity remains largely unknown. In a biodiversity field experiment, we examined the effects of plant diversity and identi...

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...

A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line 2n = 2x = 14. The chromatin of F. pratensis and L. perenne can be distinguished by genomic in situ hybridization (GISH), and it is therefore possible to visualize the substituted F. pratensis chromosome in the L. perenne background and to study ch...
