This study was carried out to determine the effects of protected cultivation on the earliness, yield, and fruit quality characteristics of some low chill peach-nectarine cultivars grown in the eastern Mediterranean region of Turkey. 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. 'Astoria' cultivar reached the highest cumulative yield as 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. The heat accumulation was 30% higher for GDH30 in the protected. 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.
Turkey is one of the main genetic origins of figs (Ficus ssp.). The study was
carried out to determine the phenotypic variation of fig genotypes grown in
Tarsus, Mersin, in the eastern Mediterranean region of Turkey. In the study,
24 female fig genotypes selected from Tarsus were investigated based on
plant and fruit quality characteristics. Only Haziran ?nciri ripened the
breba (first) crop and the other genotypes ripened the main crop. The fruit
weight of the fig genotypes ranged between 22.37 g and 90.16 g, total
soluble solids content (TSS) ranged between 12.6 and 25.0% and TSS/acidity
ranged between 29.2 and 161.5. From the plant and fruit characteristics, 26
out of 45 attributes were determined to be more appropriate in the
identification and discrimination of the fig genotypes in the research area.
Siyah ?ncir6, Bardak1, Sar? ?ncir1 and Siyah ?ncir3 genotypes were the
highest in overall quality parameters. The results showed that the measured
plant and fruit characteristics of the fig genotypes have significant
phenotypic variations.
The aim of this study was to examine the effects of Bud Feed application on fruit set, yield and fruit quality in Mikado and Mogador apricot cultivars. Methods and Results: In the study, Bud Feed (6 L 100 L -1 ) was applied 35 days before bud break. As a result of the study, Bud Feed application increased the initial fruit set by 14.41% in the 'Mikado' cultivar and 22.40% in the 'Mogador' cultivar compared to the control plants. In both cultivars, Bud Feed application provided 2-day earliness. This application has been found to be more effective in increasing the yield per tree and yield per decare (25.29 kg tree -1 and 4.22 ton da -1 , respectively) in the 'Mogador' cultivar. In addition, Bud Feed application has improved fruit size and red color formation in the fruit skin in 'Mikado' and 'Mogador' cultivars. Conclusions: Bud Feed application has been found positive in terms of improving the yield and quality of apricots in the seasons when the chilling duration is insufficient. Significance and Impact of the Study: Insufficient winter temperatures in the Mediterranean Region may cause yield losses in early apricot cultivars. The results showed that Bud Feed application ın 'Mikado' and 'Mogador' apricot cultivars can be used in early apricots to solve this problem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
