Abstract

This study was carried out to determine the effects of protected cultivation on the earliness, yield, and fruit quality characteristicsof some low chill peach-nectarine cultivars grown in the eastern Mediterranean region of Turkey. Phenological observations, yieldparameters, and fruit quality characteristics were investigated. The chilling durations as CH (chilling hours), CU (chilling unit), and heataccumulations were determined. The ‘Astoria’ cultivar reached the highest cumulative yield of 29.11 kg/tree and 38.72 t/ha, and fruit sizewas 131.89 g and 61.74 mm in protected cultivation. The CH and CU values under protected cultivation were 28% and 40% lower thanin open area cultivation, respectively. The heat accumulation was 30% higher for GDH30 in the protected cultivation. The results of thisstudy revealed that low chill peach-nectarine cultivars grown in protected cultivation showed variable earliness, yield, and fruit qualitydepending on chilling duration and heat accumulation.
