Özet

The aim of this study was to determine plant dry matter and contents of N, P, K, Ca, Mg, Fe, Zn, Mn and Pb of corn cultivars (Akpinar, TTM813, Karadeniz yildizi) grown in nutrient culture until flowering in relation to increasing Pb levels (0, 0.5, 1, 2, 5 and 20 ppm Pb/pot). In this study one-week-old maize seedlings grown in Arnon's nutrient culture were transferred to the nutrient solution with or without Pb. Significant variations in accumulation and non-tolerance to Pb in corn cultivars were observed. In all the cultivars of maize dry matter content decreased and accumulation of N, P, K, Ca, Mg, Fe, Zn and Mn were inhibited.
