Phenological observations, yield parameters, and fruit quality characteristics were investigated:The chilling durations as CH (chilling hours), CU (chilling unit), and heat accumulations were determined. The 'Astoria' cultivar reached the highest cumulative yield of 29.11 kg/tree and 38.72 t/ha, and fruit size was 131.89 g and 61.74 mm in protected cultivation. The CH and CU values under protected cultivation were 28% and 40% lower than in open area cultivation, respectively. The heat accumulation was 30% higher for G DIH30 in the protected cultivation. The results of this study revealed that low chill peach-nectarine cultivars grown in protected cultivation showed variable earliness, yield, and fruit quality depending on chilling duration and heat accumulation.eninfo:eu-repo/semantics/openAccessEarly harvestpeach-nectarineperformanceprotected cultivationArticle45219120210.3906/tar-2005-302-s2.0-85104174862Q1437988WOS:000637053700007Q2
