Fungal species richness and composition within needles and twigs in 55 stands of Pinus halepensis, spread out over the whole Iberian Peninsula, were determined. The aim was to evaluate the relationships of fungal communities with local environmental variables, in order to analyze the potential causes of the current decline of this pine species in Spain. A(More)
To improve the nutritional value of durum wheat and derived products, two foliar Se fertilisers (sodium selenate and selenite) were tested at four rates (0-10-20-40gha(-1)) in 2010/2011 and 2011/2012 in southwestern Spain. There was a strong and linear relationship between total Se or selenomethionine (Se-Met) accumulation in grain and Se dose for both(More)
Selenium (Se) biofortification of barley is a suitable strategy to increase the Se concentration in grain. In the present paper, the suitability of this Se-biofortified grain for making Se-enriched beer is analyzed. The aim of the present study was to evaluate the effect of different Se fertilizer doses (0, 10, and 20 g of Se ha(-1)) and forms (sodium(More)
Kentucky bluegrass (Poa pratensis L.) is a very common grass species with a wide distribution, including in Mediterranean areas. The objective of this study was to investigate the effects of non-clavicipitaceous fungal endophytes on forage production by P. pratensis, and on the nutritive value and mineral status of its herbage. Plants were inoculated with(More)
Trifolium subterraneum is a legume species which is valuable for feeding livestock and frequently used as a forage crop in countries with temperate or Mediterranean-like climates. The aim of the present work was to evaluate the effect of six leaf fungal endophytes on biomass production, nutritive value and mineral status of T. subterraneum forage. Plants(More)
BACKGROUND Millions of people have Se-deficient diets and Se-biofortified crops could prevent such deficiency. The aim of the present study was to evaluate the potential of chickpea for use in Se fertilization programs in order to increase available Se. Two foliar Se fertilizers (sodium selenate and sodium selenite) at four rates (0, 10, 20, 40 g ha(-1))(More)
Selenium (Se), which has antioxidant, anticancer, and antiviral properties, is an essential micronutrient for humans and animals. This micronutrient is found in high quantity in legumes. Peas have an ever-increasing importance in Spain, and to increase their nutritional value, two foliar Se fertilizers: sodium selenate and sodium selenite, at five different(More)
Yellow serradella (Ornithopus compressus), a valuable pasture species in Mediterranean areas, presents a high diversity of endophytic mycoflora. In the present work, the hypothesis of a significant effect of fungal endophytic species on the parameters of forage production, nutritive value and mineral status of herbage was tested. O. compressus plants were(More)
Sphaeropsis sapinea sensu lato is a conifer fungal pathogen that causes shoot blight and stem cankers. Recently, the former S. sapinea has been divided into two species, Diplodia pinea and D. scrobiculata. The aims of the study were to determine the contribution of each species in disease development on red and jack pines by means of co-inoculations and(More)
Zymoseptoria tritici is a major fungal pathogen which can cause serious loss in bread-making wheat. In this study, field experiments were conducted over two growing seasons to evaluate the effect of fungicide treatment (1- or 2-sprays of prothioconazole and tebuconazole) on Septoria leaf blotch (SLB) severity, wheat grain yield, hectolitre weight, crude(More)
