Özet

Background: The effects of exogenously applied H2O2 on growth, water status, the mineral ion content (Na+, K+, Ca2+, Mg2+ and Cu2+), proline, total sugars and soluble proteins were assessed in leaves of maize (Zea mays L.) cultivars, Akpinar and Pegaso exposed to excess copper (0.5 mM). Seedlings were grown in equal-sizes plastic pots and irrigated with Hoagland nutrient solution containing H2O2 or/and copper. Different treatments taken for pot experiments were named as the control (C), H2O2 treatment only (H2O2), excess Cu (Cu) and, Cu stress combined with H2O2 pretreatment (Cu + H2O2).
