This work was carried out during 1998/1999 and 1999/2000 seasons to study the effect of picking date of “Triumph" and “Costata" persimmon on some quality attributes during cold storage for 8 weeks at 1^oC & 85-90% R.H. Fruits were harvested after 146, 153, 160, 167 days, and 158, 165, 172, 179 days from full bloom for “Costata" and “Triumph" cvs., respectively. Periodical sampling during storage indicated that weight loss % increased as time progressed in storage, and this was significantly higher in “Triumph" than “Costata" cv. It was also found that total acidity, firmness, vitamin C content, tannin content and total chlorophyll content decreased as maturity progressed and with time in storage. However, fruit SSC % and carotene content increased in the later harvesting dates as well as during storage. It could be concluded that the best picking date for “Costata" and “Triumph" cvs. under the conditions of this experiment is 167 and 179 days from full bloom, respectively. This will achieve best postharvest fruit quality.
