The experiment was carried out outdoors on 2-year-old ‘Reclchief’ apple plants planted in containers filled with two soiis (pH 4 and 6.5) and fertilized with B (0, 1, 3 and 5 mg kg-1 soil). At the end of the experiment, B concentration in soil was significantly and positively correlated with the B doses applied. Increasing the doses of added B, the fresh weight of plants and B concentration in leaves were significantly increased. However, leaf N concentration was negatively correlated with B concentration in soil. The number and length of lateral shoots and the height of plants were not influenced by B nutrition. Chlorophyll concentration in leaves was reduced at higher B treatments only in plants grown in acid soil.
