The study was conducted in 2007–2009. Winter rape, spring rape, white mustard, Chinese mustard and winter wheat were grown as previous crop for winter wheat cv. Olivin. Wheat was grown under the conventional and intensive technology with full fungicidal protection and increased nitrogen rates (from 210 to 270 kg/ha depending on the previous crop). The infection rates of leaf blotch varied widely from...
The study, covering analysis of the variation in the intensity of septoria leaf spot, made use of the results obtained in Post-registration Variety Testing experiments carried out in Lower Silesia. Of these experiments, eight locations characterized by diverse soil conditions were selected. The analysis regarded a three-year period of cultivation, spanning 2004–2006, of eleven winter wheat cultivars...
Genotype-dependent variation in water stress-induced tissue dehydration (RWC), proline accumulation (PA), membrane injury (MI) and stress resistance (R) was studied among old and modern cultivars of winter wheat (Triticum aestivum L.). Twenty-day- old seedlings grown in nutrient solution were subjected to a moderate water stress (-0.75 MPa) by immersing (for 72 h) their root systems in aerated nutrient...
Studies on sensitivity of microorganisms colonizing the leaves of winter wheat cultivar Almari to Amistar 250SC, Bravo 500SC fungicides and Bion 50WG plant resistance stimulator were performed in 2000-01. The studied fungicides decreased growth of hyphae fungi colonizing the leaves of winter wheat cultivated in pots, especially 24 hours after treatment, compared to control. Created free ecological...
