Sclerotinia sclerotiorum causes serious yield losses in oilseed crops worldwide. Bacillus subtilis Tu-100 significantly reduced (P≤0.05) the incidence of disease caused by S. sclerotiorum on oilseed rape at harvest in two trials conducted in fields artificially infested with this pathogen. Mean plant dry weight was significantly greater (P≤0.05) and mean plant length was significantly greater (...

Following a request from the European Commission, the Panel on Genetically Modified Organisms of the European Food Safety Authority (EFSA GMO Panel) evaluated the documentation provided by Austria to support the prolongation of the safeguard clause measure prohibiting the placing on the market of the genetically modified oilseed rape event GT73 for import, processing and feed uses in Austria. T...

seed weight (sw) in oilseed rape (brassica napus l.) is determined during the seed filling period (sfp). a great proportion of variation in sw is associated with environmental conditions in this period. to quantify factors determining sw in open pollinated (op) and hybrid cultivars of oilseed rape, 12 field experiments were conducted at agricultural research station of gonbad, iran, during 2000...

Crops transformed to express Bacillus thuringiensis (Bt) toxins can cause close to 100% mortality of certain target pest species. This study assessed the effect of target pest reduction on the predatory insect Chrysoperla carnea (Stephens) in the presence of alternative prey. Numbers of lacewings recovered from Bt oilseed rape (cultivar Oscar, event O52) did not differ significantly from number...

The aim of this study is to assess the interception and transfer to edible part of wet deposited 134Cs and 85Sr to spring oilseed rape and spring wheat and the dependency of the intercepted fraction on the development stage e.g. the total plant biomass. The radionuclides, 134Cs and 85Sr, were deposited at six different development stages using a rainfall simulator. The results showed that there...

Oilseed rape (Brassica napus) is one of the major oilseed crops in the world but is vulnerable to attack by many pathogens and insect pests. In addition to the host plant genotype, micro-organisms present in the rhizosphere and within plant tissues affect the susceptibility to plant pathogens. While rapid progress has been achieved concerning the concept of plant resistance genes, information o...

nineteen irrigated farms of canola from six cities of khorasan selected to assess the seedling emergence one month after sowing in 2009. soil texture of each farm determined using the hydrometer method. the results showed that weather conditions of sowing areas had no significant effect on emergence of oilseed rape. with increasing the temperature (within the range of 19.5 to 21.5 ˚c) emergence...
