“…As shown in Table 2, with the extension of storage, the skin chromaticity parameters L*, a*, and b* of sweet cherries fruit all decreased, indicating that the skin color of the fruit gradually darkened, and the red and yellow gradually decreased. Previous studies have reported that the skin color parameters L*, a*, b*, chroma, and hue angle of sweet cherry fruits showed downward trends during postharvest storage (Esti et al, 2002;Sharma et al, 2010;Zhang et al, 2020). In the early stage of storage, the skin color of shelter-free fruit was the brightest (largest L* value) and this fruit was redder and yellower (higher a* and b* value) than those under the arched-shelter and umbrella-shelter conditions.…”

This study investigated the effects of different shelter coverings (arched-shelter and umbrellashelter) on the volatile components of sweet cherry mature fruits in rainy areas, and the postharvest quality of these fruits during storage at room temperature. A total of 68 volatile compounds were identified and semiquantified in mature fruits. Aldehyde compounds were the most abundant, followed by alcohols. Benzyl alcohol, acetaldehyde, 2-methyl-propanal, hexanal, (E)-2-hexenal and benzaldehyde were the major volatiles, and the proportions of these compounds were greatly affected by different shelter coverings. With the extension of the storage period, the color parameters (L*, a* and b*), texture parameters (hardness, springiness, chewiness, resilience, skin strength and flesh firmness) and titratable acidity of the fruit rapidly decreased. The total soluble solid content and weight loss of the fruit gradually increased. Principal component analysis indicated that the sweet cherry fruits from the arched-shelter had the best quality and the longest shelf life. Efectos de diferentes coberturas de protección contra la lluvia en los compuestos orgánicos volátiles de la fruta madura y la calidad poscosecha de la cereza dulce RESUMENEn este estudio se investigaron los efectos provocados por diferentes coberturas de protección (arco-cobertizo y paraguas-cobertizo) en los componentes volátiles de los frutos maduros de cereza dulce en zonas lluviosas, y la calidad poscosecha de estos frutos durante su almacenamiento a temperatura ambiente. En los frutos maduros se identificó y semicuantificó un total de 68 compuestos volátiles. Los compuestos aldehídicos fueron los más abundantes, seguidos de los alcoholes. El alcohol bencílico, el acetaldehído, el 2-metil-propanal, el hexanal, el (E)-2-hexenal y el benzaldehído fueron los principales compuestos volátiles detectados. Las proporciones de estos compuestos se vieron muy afectadas por las diferentes coberturas de protección. Al prolongarse el periodo de almacenamiento, los parámetros de color (L*, a* y b*), los parámetros de textura (dureza, elasticidad, masticabilidad, resiliencia, resistencia de la piel y firmeza de la pulpa), así como la acidez valorable de la fruta, disminuyeron rápidamente. El contenido total de sólidos solubles y la pérdida de peso de la fruta aumentaron gradualmente. El análisis de componentes principales indicó que los frutos de cereza dulce bajo la protección arqueada poseen mejor calidad y su vida útil es más larga.

The branch waste of sweet cherry trees is an organic byproduct that is inevitably produced during the pruning process. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) were used to analyze and compare the differences in the chemical composition and the presence of macroelements of sweet cherry branches. The FTIR absorption spectra were analyzed, and the following absorption peaks were found: 1632 cm-1 for lignin, 1740 cm-1and 1244 cm-1 for hemicellulose, and 1316 cm-1 for holocellulose. The results showed that the lignin content in the bark was higher than that in the xylem, and the content of hemicellulose and holocellulose in the xylem was higherthan that in the bark. The XPS survey showed that the contents of C-C (9.89% and 15.59%, respectively) and C=O (31.52% and 15.59%, respectively) in xylem and bark were quite different; the xylem had a higher cellulose content, while the bark had a higher lignin content. In the xylem, the proportion of C-O was the largest (12.55%), while in the bark, the proportion of C=O was the highest (5.93%). The research results are significant for revealing the chemical composition and structural morphology of the xylem and bark of sweet cherry branches.
