ResumoFlowering in Aeschynanthus speciosus Hook was studied in 8 climates; short days (SD, 8 h) and long days (LD, 20 h) combined with 12, 15, 18 or 21°C. The experiments were performed 4 times within a 2-year period. Time until first flower opened decreased and percent flowering plants increased with increasing temperature. In 2 experimental periods, LD caused shorter time to first flower opened, higher percent flowering plants, and formation of fewer leaves prior to flower primordia. Increase in temperature also resulted in fewer leaves. In the other 2 periods, no consistent day-length effects were found and number of leaves prior to flower primordia was not affected by temperature. Further investigations are needed to give an accurate description of the effects of temperature and day-length on flowering in Aeschynanthus speciosus.
