摘要: ABSTRACT The response of potted pear trees grafted on quince (Cydonia oblonga Mill.) Sydo stock to increasing concentrations (0, 50, 100, 200, 400, 600, 800, and 1000 mg kg−1) copper (Cu) in sandy clay-loam soils were evaluated crop toxicity thresholds symptoms determined. Reductions shoot growth leaf area observed only for grown soil with more than 400 Cu/kg. During the growing season, carbon assimilation microbial biomass reduced as concentration Cu increased. However, effect was always stronger soil. Copper accumulated roots, additions described by a linear quadratic function soil, respectively. A possible antagonism between zinc (Zn) roots. Root Zn decreased
