Theobroxide has been shown to induce potato tuberization and flower-bud formation in morning glory under non-inductive photoperiodic conditions, stimulating the activity of lipoxygenase (LOX) and the synthesis of jasmonic acid (JA). In the present study, the ability of theobroxide to overcome the inhibitory effect of unfavorable high temperature on the induction of tubers in potato and flower buds in morning glory was examined. Both tuber induction and flower-bud formation under non-inductive high temperatures were promoted by the application of theobroxide at a high concentration. However, although theobroxide treatment resulted in an increase in fresh weight during potato tuber growth at 30°C, morning glory plants treated with theobroxide at 35°C failed to bloom, implying that theobroxide may assist only in flower-bud formation.
