Abstract

The effect of different concentrations (0.25 mM and 0.5 mM) of Cu 2+ on growth, anatomical parameters, malondialdehyde (MDA) content, photosynthetic pigments were investigated in hydroponically grown five barley ( Triticumaestivum L.) varieties (Kazakhstan skayarannaya Kazakhstanskaya-3, Melturn, Kaiyr and Shagala). Wheat varieties exposed to 0.5 mM Cu2+ exhibited significant growth reduction. The results showed that growth, anatomical and biochemical parameters were significantly reduced at 0.5 mMCu 2+ , compared to untreated control plants. Tolerant and sensitive to Cu 2+ wheat varieties were identified. MDA content in tolerant variety was less compared with sensitive to copper ones.In tolerant varietyphotosynthetic pigments (chlorophyll- a , chlorophyll- b , carotenoids) content decreased in less extent compared with sensitive varieties.
