Fusarium head blight is an important disease attacking wheat (Triticum spp.), barley (Hordeum vulgare) and other grains worldwide. Among the Fusarium species causing this disease, Fusarium poae is less often implicated, but is a fungus of increasingly recognized importance and it is associated with human and animal toxicoses. The aim of this study was to examine the responses of wheat and barley varieties to inoculation by different F. poae isolates, in order to observe contamination by this fungus in the grains. The analyses were performed during 2008, 2009, and 2010 under natural conditions at the Facultad de Agronomía de Azul-UNCPBA, province of Buenos Aires, Argentina. Statistical analyses were carried out and the identities of re-isolated isolates... |

Arsenic (As) and Fluoride (F) are present in many soils, affecting crops and posing risks in the food chain. We performed pot experiments on spiked soils enriched in these elements either individually or simultaneously, over a wide range of concentrations. Soybean biomass production, grain yield, As and F accumulation and distribution within the plant, and the antioxidant response to these stresses were analyzed. Arsenic was more toxic than F. At As levels >35 mg/kg and F levels >375 mg/kg, yield loss reached 60% and 30%, respectively. At the highest dose of As plants died within 2 weeks, whereas F showed no lethality. When they were applied simultaneously, detrimental effects were more important. As and F in plants increased in all soybean organs... |
