Abstract The introduction of well-adapted species, such as Trifolium subterraneum (subclover) and Poa pratensis (Kentucky bluegrass), might enhance the forage yield quality dehesa pastures for feeding livestock. However, climatic hardness poor soils in these agrosystems may limit plant establishment development. Since fungal endophytes have been found to alleviate environmental stresses their h...

North American and Eurasian isolates of Wheat streak mosaic virus (WSMV; genus Tritimovirus) and Oat necrotic mottle virus (ONMV; genus Rymovirus) were examined. Nine WSMV isolates differentially infected oat, barley, inbred maize line SDp2 and sorghum line KS56. The WSMV isolates clustered into groups based on phylogenetic analyses of the capsid protein (CP) cistron and flanking regions. WSMV ...

Ergot, caused by Claviceps purpurea (Fr.:Fr.) Tul., is an important disease of grasses grown for seed. Ergot can be especially severe in Kentucky bluegrass (Poa pratensis L.) seed production, with yield losses estimated as high as 25% (2). Claviceps purpurea invades the ovary, replacing the potential seed with a hard black sclerotium. Sclerotia are typically one to several times longer than the...

A revision and key to the 23 species and eight subspecies of Poa (including Dissanthelium) known to occur in Mexico is provided. All voucher specimens seen are cited for accepted taxa, except Poa annua for which one voucher per state is provided. Taxa not previously known from, or poorly understood in, Mexico are discussed.Poa palmerisp. nov. is endemic to forested slopes of the Sierra Madre Or...

Previous study has shown a likely link between increased shoe- surface traction and risk of knee Anterior Cruciate Ligament (ACL) injury. Portable natural grass systems are being used more often in sport, but no study to date has investigated their relative safety. By their nature, they must have high resistance to falling apart and therefore newly laid systems may be at risk of creating excess...

Two experiments (Exp) were conducted to examine in vitro the release of gonadotropin releasing hormone (GnRH) from the hypothalamus after treatment with naloxone (NAL) or morphine (MOR). In Exp 1, hypothalamic-preoptic area (HYP-POA) collected from 3 market weight gilts at sacrifice and sagittally halved were perifused for 90 min prior to a 10 min pulse of morphine (MOR; 4.5 x 10(-6) M) followe...

Although studies have shown that chemokines are pyrogenic when injected into the brain, there are no data indicating which cell types and receptors in the CNS are employed by chemokines such as CCL3 (synonym: MIP-1α) to induce fever in rats. We aimed to study, whether CCL3 induces fever when injected directly into the thermoregulatory center within the pre-optic area (POA). Moreover, we investi...

A study was conducted in northern Colorado to evaluate the effectiveness of two compost products on improvement turfgrass color and quality, necrotic ringspot (NRS) disease suppression, thatch reduction. Two Kentucky bluegrass (Poa pratensis L.) home lawns with a history NRS were chosen for study. Treatments applied twice during 2018 growing season after all plots aerated consisted (a) inoculat...

This paper reviews research on phytoremediation (2002–2021), particularly for the estimation of plant efficiency and soil pollution indices, examining extraction metals from plants growing under both artificial (spiked with specific metal) natural conditions. From analysis >200 published experimental results, it was found that contamination factor geo-accumulation index as well translocation...
