Effects of graduated applications of nitrogen on yield and quality of winter and spring wheat cultivars. 2


, : Effects of graduated applications of nitrogen on yield and quality of winter and spring wheat cultivars. 2. Zeitschrift fur Acker und Pflanzenbau 146(3): 204-221

Results of a 3-yr series of trials applying late N dressings to 10 of winter wheat and 7 of spring wheat are reported. Late N dressings to improve grain quality should not be applied before flowering in normal growing conditions. These dressings were profitably combined with increased doses of P fertilizer and were efficient measures against ear diseases. Grain quality measured as protein content increased after higher rates of early N dressings as well as after late N dressings.

The transcription factors encoded by the E2A gene are known to be essential for B lymphocyte development, and ectopic expression or gene inactivation studies have revealed several potential lineage-specific E2A target genes. However, it remains un...

MHC II uveal melanoma vaccines are MHC class I(+) uveal melanoma cells transduced with CD80 genes...
