“…Generally hand thinning and NAA applications increased TSS content in comparison to control and carbaryl. Chira et al (1999) studied 'Comandor', 'Dacia', and 'Olympia' apricot and found the best results were obtained when thinning was done 25 days after full bloom. They also found that higher rates of thinning generally increased the TSS, which confirms my results.…”

To cite this article: Levent Son (2004) Effects of hand and chemical thinning on fruit size and quality of 'Priana' and 'Beliana' apricot (Prunusarmeniaca) Annual apricot production is 100 000 t. The importance of the area is its earliness. This thinning study was carried out on 'Priana' and 'Beliana' apricot in 2002. In this experiment, 30%, 50%, 70% hand thinning; 1000, 1500, 2000 ppm carbaryl, and 10, 20, and 30 ppm naphthalene acetic acid (NAA) were applied. The main objective of this work was to improve fruit quality characteristics. All treatments significantly increased fruit weight. The biggest fruit were obtained from 20 ppm NAA, 70% hand thinning, and 1000 ppm carbaryl for both apricot cultivars. The soluble solids (TSS) were greatest (13.53%) for 70% hand thinning and 20 ppm NAA in 'Priana'. When the fruit weight, average size of the fruits, and flesh/ seed ratios were considered; 70% hand thinning, 20 ppm NAA, and 1000 ppm carbaryl treatments were found more effective than the others in both apricot cultivars. The earliest treatments were 50% and 70% hand thinning and 20 ppm NAA in 'Priana' ; 70% hand thinning, 20 and 30 ppm NAA in 'Beliana'. All thinning applications caused 1-2 days earliness in comparison with control fruits.

“…Combinations of NAA+carbaryl have been successfully used for apples (Jones et al 1990;Zika et al 1990). Chira et al (1999) reported the best results obtained when thinned 25 days after blossom in 'Comandor', 'Dacia', and 'Olympus' apricot. They also found the index of the economical efficiency was higher than control.…”
