Abstract :Boron tolerance of 13 hybrid maize cultivars was investigated. The experiment was carried out under greenhouse condi-tions. Boron was applied to the soil at 0, 0.625, 1.25, 2.5, 5, 10 and 40 mg kg-1 levels as H3BO3. Dry weights and B concentration and B uptake of the plants were determined at the end of the experiment. Boron tolerance of the corn cultivars was determined from the relationships between dry weights and B concentration and B uptake rates. According to the results, B tolerance of cultivars from high to low was as follows: P 3394 ve RX 770, BC 566, LUCE, MAT 97, TTM 815, T 1595, LG 60, LG 55, DK 585, PIAVE and DK 647 ve TTM 8119. In general, B concentrations of low tolerant cultivars were higher than those of high B tolerant cultivars.
