In a nutrient-solution experiment, the B content of leaf blades, petioles and stems of sesame plants was highly correlated with the B content of the substrate. B content was highest in the leaf blades and lowest in the stem. Concentrations of more than or equal to 5 mg B/l inhibited growth and seed production and resulted in leaf necrosis and premature leaf drop. Foliage of plants receiving excess B contained >700 mu g B/g (DM basis).
