Comparison of pollinator effect on the abscission of flowers and fruits of 3 pistachio cultivars showed that pollens of Pistacia vera L. may increase or reduce flower and fruit abscission. Flower and fruit abscission occurred primarily during the flowering and small-fruit period, that the June and pre-harvest abscissions were low. Data collected for 3 consecutive years revealed that 83.4 to 88.2% of the flowers and fruits of Kirmizi pistachio cultivar abscised mainly during an initial 50 days after Full Blooming (FB). Siirt cultivar abscised during an initial 35 days after FB with a rate of 82.1 to 90.9%. Abscission rate of Ohadi cultivar were 84.5 to 88.6% that occurred during an initial 50 days after FB period. Males noted as 12 and 13 resulted the highest abscission in Siirt cultivar. Results demonstrated that pollinators affect flower and fruit abscission in pistachio.]]>Acar, I.,1997pp: 92pp: 92Acar, I., B.E. Ak and H.
