EFFECTS OF ETHYLENE APPLIED BEFORE FLOWER-BUD INITIATION ON FLOWERING OF TULIPS

Bulbs pretreated with high temperature and ethylene showed higher flowering percentage and earlier flowering when subjected to precooling without storage at 20°C, or grown under high temperature conditions. The high temperature with ethylene exposure reduced the number of days to flowering by a few days, when bulbs were subjected to precooling after reaching G stage. The exposure of marginal sized bulbs to ethylene after the high temperature treatment induced higher floral initiation.
