Abstract : Observations were made on a single tree of this relatively new hybrid cultivar during 1992-93. The inflorescence was a conical panicle, the rachis turning from light green to bright pink when fully expanded. There were an average of 947.9 flowers/panicle, of which 75.73% were perfect. Anthesis occurred throughout the day, but especially between 07.00 and 11.00 h. Pollen viability was 93.75%. Stigma receptivity was greatest on the day of anthesis and ceased after 3 days. Fruit set averaged 20.76% across all flowers and 28.22% for perfect flowers. Self fertilization resulted in 32.5% fruit set. Fruit retention was 0.128% of fruits set, with 0.29 fruits retained/panicle.
