Bud break onset, flowering, fruit set and fruit drop rates and fruit growth were recorded in Diospyros kaki cv. 'Fuyu'. In general, final bud break rate was low and seemed to be greater in the northern and southern parts of the tree canopy. Bud burst rate on each of the three different wood ages was canopy-orientation dependent. Flowering occurred between April 5 and May 17. Final flowering rate averaged 37 per cent. Fruit set rate was rather low, suggesting either a defective pollination or a negative consequence of an on-off yielding. Fruit growth rate was high shortly after fruit set but decreased irregularly after mid-July. Final fruit diameter did not exceed 7 cm and final average yield amounted to 3.9 kg per tree. Fruit drop was very high during the two weeks that followed fruit set and low and regular thereafter up to the end of the season. Total fruit drop averaged 82 per cent.
