The experiment was carried out outdoors on 2-years-old Redchief apple plants planted in containers filled with two soils ( pH 4 and 6.5) and fertilised 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 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.
