Fusarium graminearum and F. culmorum are the causal agents of Fusarium head blight (FHB) in cereal crops worldwide. Application of resistant cultivars is the most effective and economic method for management of FHB and reducing mycotoxin production in wheat. Understanding the physiological and biochemical mechanisms involved in basal resistance of wheat to FHB disease is limited. In this research,...
The species structure of plant parasitic nematode populations from the rhizosphere of winter wheat grown with crop rotation or in 48-year-old monoculture was analyzed and compared. Dominating species: Bitylenchus dubius, Merlinius microdorus, Paratylenchus neglectus and Heterodera avenae, in monoculture plots, had higher populations than in crop rotation plots. Heterodera avenae eggs and larvae were...
Concerns about food quality and environmental protection have led to the search for effective and safe insect control measures. This study was carried out to evaluate the efficacy of some insecticides (malathion, alpha-cypermethrin, lambda-cyhalothrin) and clove oil, alone and in combinations, to protect wheat grain against Rhyzopertha dominica. Adult mortality, progeny emergence and weight loss of...
This research was conducted to investigate the natural, quantitative composition of the most common Fusarium species directly in fields of northeastern Poland. The concentration of Fusarium spp. and grain quality traits (yield, 1,000 kernel weight, test weight, grain moisture, ergosterol content, protein content, gluten content and starch content) were compared in four wheat varieties (Mandaryna,...
Eyespot is one of the most important fungal diseases of the stem base of wheat (Triticum aestivum L.). The presented study clearly demonstrated that the Pch1 gene was the main effective source for reducing the eyespot disease score in the analyzed winter wheat lines. Nevertheless, Pch1 was present only in 8−9% of the investigated lines. Using an isoenzymatic marker and molecular markers, the presence...
Parasitic weeds especially Phelipanche aegyptiaca decrease severely the production of canola. This study evaluated the effect of intercropping different wheat genotypes with canola on Phelipanche aegyptiaca growth. Ten wild wheat genotypes with different ploidy levels including TRI11712, TRI19322, TRI18664, TRI19652, TRI565, TRI15593, TRI12911, TRI11554, TRI17606, TRI7259P and seven cultivated bread...
The recent advances in nanotechnology and its use in the field of agriculture are astonishingly increasing; therefore, it is important to understand their role in plant life. Four wheat cultivars soaked in different concentrations of TiO2-NPs (0.0%, 0.025 %, 0.05 %, 0.1 %, 0.2 % and 0.5 %) to select a concentration that stimulate cultivars growth under normal conditions during germination stage. Cultivar...
The main objective of this study was to determine the effect of cultivation technologies (extensive vs. high-input) on correlations between wheat grain quality parameters, such as falling number value, wet gluten content and grain hardness, and the content of phenolic compounds, such as total free phenolic compounds and alkylresorcinols. ąIt was found high values of correlation coefficient between...
Eyespot can reduce yields, even up to 50%. There are four genetically characterized resistances in wheat varieties, controlled by: (1) the Pch1 gene, transferred from Aegilops ventricosa; (2) the Pch2 gene, originating from wheat variety Capelle Desprez; (3) the Pch3 gene, originating from Dasypyrum villosum; and (4) the Q.Pch.jic-5A gene, a quantitative trait locus (QTL) located on chromosome 5A...
A Polish isolate of Soil-borne wheat mosaic virus (SBWMV-Pol1) was characterized by limited pathogenicity and a low concentration of virus particles in infected plant tissues. The aim of this research was to consider the possibility of seed-transmission dissemination of the virus. Seeds of winter wheat cv. Muszelka served as material for the studies. Two methods were involved in the diagnostics of...
