Instances of severe degradation of gluten proteins that resulted in an almost complete loss of gluten functionality were observed in some lots of Norwegian wheat. Humid and cool conditions, in addition to moderate temperatures during booting, were associated with increased HT2 T2 accumulation in harvested oat grains, whereas warm and humid weather during stem elongation and inflorescence emergence, or cool weather and absence of rain during booting reduced the risk of HT2 T2 accumulation. Opinion of the Panel on Plant Health of the Norwegian Scientific Committee for Food and Environment. Available at: risk assessment of Dendrolimus sibiricus and Dendrolimus A prediction model, including only pre-flowering weather conditions, adequately forecasted risk of DON contamination in oat, and can aid in decisions about fungicide treatments. S., Koga, S., Aamot, H., Böcker, U., Lysøe, E., Brodal, G., Dill-Macky, R.

K., Böcker, U., Lysøe, E., Brodal, G., Dill-Macky, R. A project was established to generate greater knowledge of the interface between gluten functionality and effects of Fusarium species and other microorganisms on Norwegian wheat quality. G., Effect of microorganisms on gluten quality in wheat., in Faculty of Biosciences. Our data show that adequate predictions of the risk of HT2 T2 in oat grains at harvest can be achieved, based upon weather data observed during the growing season. Pest risk assessment of Dendrolimus sibiricus and Dendrolimus superans. Norwegian Scientific Committee for Food Safety and Environment (VKM), Oslo, Norway. Prior to harvest, warm and humid weather conditions followed by cool and dry conditions were associated with a decreased risk of DON accumulation.

and mycotoxins was observed in some grain lots [1, 2]. Furthermore, we developed a mathematical model to predict the risk of HT2 T2 in oat grains. Associations between Fusarium mycotoxin accumulation in oats and weather conditions (Lecture). Warm, rainy and humid weather during and around flowering increased the risk of DON accumulation in oats, as did dry periods during germination/seedling growth and tillering. Effect of microorganisms on gluten quality in wheat (Poster).

Some of these candidates were inoculated on wheat during flowering [3]. These findings are in contrast with a previous study examining the risk of deoxynivalenol contamination in oat reporting that toxin accumulation was mostly influenced by weather conditions from flowering onwards. Numerous (454 isolates) fungi were successfully isolated, purified and stored using agar slants and cryopreservation. taeda) and was morphologically and molecularly identified. Association between Fusarium mycotoxin accumulations in oats and weather conditions (Lecture).

Analysis of baking quality of the flour from this experiment revealed a reduced proportion of un-extractable polymeric proteins (%UPP) and severe reductions in the gluten’s resistance to stretching (RMAX) in wheat flour from plants inoculated with Fusarium graminearum. Hofgaard, I., et al., Associations between Fusarium species and mycotoxins in oats and spring wheat from farmers’ fields in Norway over a six-year period. Sydowia polyspora was isolated from six different seed lots from three Pinus species (P. Koch’s postulates was fulfilled by inoculating one year old seedlings (wounded and unwounded) with a spore suspension (107 ml-1) obtained from 30 day old pure cultures grown on PDA.

Hence, there is considerable interest both from the forest sector and politicians to invest in infrastructure that can provide the basis for profitable forest sector development in coastal Norway.

Due to the poor infrastructure in the region, the current challenge is to harvest the maturing spruce plantations at an acceptable cost.

The assessment concluded that exceeding the TDI in infants and children is of concern. doi: 10.1007/s10658-016-1113-5 dating røde flagg å se etter i en kvinne High concentrations of the mycotoxin deoxynivalenol (DON), produced by Fusarium graminearum have occurred frequently in Norwegian oats recently. 1) Causing Stem Rot on Turnip Rape (Brassica rapa subsp. Following 1 to 2 days incubation at 20°C, fast-growing white mycelium characteristic of Sclerotinia was observed, and within 5 to 7 days, new sclerotia had started to develop. Stems started to develop white lesions with fluffy mycelium around the inoculation sites. Brassica oil seed crops are cultivated as important break crops in the cereal-based production system in Norway and can be severely affected by Sclerotinia stem rot.

In years with high mean DON concentration, the high (95th-percentile) exposure exceeded the TDI by up to 3.5 times in 1-, 2- , 4-, and 9-year-old children. European journal of plant pathology, 148(3): 577-594. Sclerotia were collected from inside infected turnip rape stubble and from harvested seeds, surface sterilized, bisected, and placed onto potato dextrose agar (PDA). Noninoculated PDA agar plugs were attached to the control plants. Symptoms typical of stem rot appeared after 1 to 2 weeks of incubation at 16 to 20°C, 100% relative humidity. White mycelium started to grow after 1 to 2 days and new sclerotia were formed within 7 days, similar to the ones used for producing the initial isolate. subarctica might be present undetected in many farmer fields.

The main decision variables are location of quays, upgrade of public road links, the length of new forest roads, and when the investments should happen.

The main objective is to provide decision support for prioritization of infrastructure investments.

To the best of our knowledge, this is the first report of the fungus being isolated and recorded within the country.
