Description
  • Collection of eleven cultivars of winter wheat plants were cultivated in field experiments in Prague-Ruzyně in growing season 2004/2005 and 2005/2006. Two levels of N fertilization (110 and 160 kg N per ha) were used. At three terms during the period of grain formation (beginning of flowering, 15 and 25 day after flowering) wheat plants were harvested and flag leaves were analyzed for contents of chlorophyll, soluble protein, total N content and activity of nitrate reductase. Higher temperature and lack of precipitation during phase of grain filling (2006) induced earlier senescence of flag leaves. In all cultivars this process was succeeded by rapid lowering of nitrate reductase activity, decrease in total nitrogen content, soluble protein content and faster chlorophyll degradation.

  • V polních pokusech v Praze Ruzyni byl pěstován soubor 11 kultivarů ozimé pšenice v sezónách 2004/2005 a 2005/2006. Byly použity dvě úrovně hnojení dusíkem (110 a 160 kg/ha). Během tvorby zrna byly ve třech termínech rostliny sklizeny a v praporcových listech byl stanoven obsah chlorofylu, rozpustných proteinů a celkového N a dále aktivita nitrát reduktázy. Vyšší teplota a nedostatek srážek v sezóně 2006 měli za následek rychlejší stárnutí praporcových listů. U všech kultivarů byl tento proces doprovázen rychlým snížením aktivity NR, poklesem obsahu celkového N a rozpustných bílkovin a rychlejší degradací chlorofylu. (cs)
