2 graph., 1 scheme, 4 tables; 30 ref. Summary (En)
Rice (Oryza sativa) plants were grown in nutrient solution containing copper concentrations from 0.002 to 6.25 g/m3. Measurements of root nitrate uptake were taken over the 30 d period following germination, measurements were also taken of root and shoot contents of Cu as well as shoot contents of molybdenum, nitrate, nitrite and pigments. Phytosynthetic electron transport activity (water to methyl viologen) exhibited an inversely proportional relationship to Cu concentrations while the activities of nitrate reductases showed no apparent correlation with the Cu concentrations, except at the highest levels
