Sažetak
The uptake of copper and lead supplied in nutrient solution (500 μ M) and their detrimental impact on photosynthetic pigments concentration and dry matter accumulation in three lettuce cultivars were investigated. The concentration of copper and lead in lettuce leaf ranged from 8.62 to 14.20 mg kg-1 leaf dry weight for copper, and from 1.97 to 4.05 mg kg- 1 leaf dry weight for lead, after two days of exposure. In copper and lead treated plants significant differences in leaf and root dry weight accumulation were not established, but concentrations of chlorophyll b and carotenoids showed significant reduction in cultivar Triatlon. In other words, tolerant genotype (cultivar Nadine) accumulated less copper and lead in leaves, the edible parts of lettuce, therefore such genotypes could be recommended for planting on potentially polluted soils.
