摘要: With the open-top chambers (OTCs) in situ Yangtze River Delta, China 2007 and 2008, effects of elevated O-3 exposure on nutrient elements quality winter wheat rice grain were investigated. Grain yield per plant declined both years. The N S concentrations increased under years C-N ratios decreased significantly. K, Ca, Mg, P, Mn, Cu Zn Mn increased. protein, amino acid lysine concentration amylose decreased. increase was less than reduction rice, and, hence, absolute amount nutrients reduced by O-3. 2013 Elsevier Ltd.
