Level of pistillate flower abscission (PFA) in Turkish walnut cultivars was investigated in this study. Emasculated and bagged female flowers were pollinated with 5%, 50% and 100% pollen concentrations at receptivity. Control flowers left for open pollination. In addition, a whole tree was sprayed with 125 ppm ethylene inhibitor AVG (amino ethoxy vinyl glycine) when anthesis reached to 5-30% and a control tree was not treated for each cultivar. Number of aborted flowers at diameter of 3-4cm was counted and percent PFA was calculated. The results showed that Turkish walnut cultivars had medium (65.4%) to high (100%) levels of PFA including the leading cultivars ‘Sebin’ and ‘Bilecik’ (94.8% and 93.4% PFA, respectively). Application of AVG reduced PFA from 82.4% to 43.6% in average and increased fruit set significantly in all cultivars except ‘Sen-1’.
