Abstract : In a field trial in Giza, foliar application of boric acid at 500-1250 p.p.m. at the late bud-swelling stage significantly increased the percentage of hermaphrodite flowers and fruit TSS, TSS:acid ratio and total sugars content. Fruit acidity was increased, but not significantly, while ascorbic acid content was significantly reduced compared with controls. The most effective boric acid concentration was 750 p.p.m.
