This study was carried out during 1995-1996 in Çukurova. In the experiment, Priana and Belliana were used as comparative cultivars. In addition, 12.5, 25, 50 ppm of NAA and 500, 1000, 2000, 4000 ppm of carbaryl and 50 % of hand thinning were applied about three weeks after full bloom. The results showed that 50 ppm NAA increased both the thinning rate and the fruit size while 1000 and 2000 ppm of carbaryl had a positive effect on the fruit size and weight without having any effect on thinning. Although the treatments gave better results on the fruit size and weight than the control, their effects on the fruit quality criteria varied depending on the cultivars and the doses of the applications. Hormone analysis showed that the level of the plant growth inhibitors was higher than that of the plant growth promoters in all treatments.
