This physiological disorder leads to severe economic losses, which can be more or less effective depending on the cracked region of the fruit: in the cheeks (side cracks), in the stylar scar region, or in the stem cavity region. Sweet cherry cracking can be affected by several factors such as cultivar, growing conditions, rootstock, fruit size, flesh osmotic potential, cuticular characteristics of the skin, and stage of fruit development. In this sense, the objective of this work was to evaluate the cracking incidence in two sweet cherry cultivars (Early Bigi and Lapins grafted on \u201cSaint Lucie 64\u201d rootstock) and correlate the cracking index with other quality parameters. Fruits were harvested on 2 May (cv. Early Bigi) and on 27 May (cv. Lapins) 2019 at their commercial ripening stage. In the field, the total yield and the trunk cross-sectional area were determined for each tree in order to calculate the yield efficiency. In the laboratory, the cracking index was determined in 150 fruits without visual defects. In addition, fruit size and weight, wax content, flesh firmness, epidermis rupture force, total soluble solids, pH, titratable acidity, and maturity index of 30 fruits were also evaluated. In general, all the analyzed quality parameters were influenced by the cultivar, being that cv. Lapins presented larger, heavier, firmer, and sweeter fruits, with more acidity and higher maturation index. However, cv. Lapins also presented higher cracking index, which was positively correlated with all the parameters above-mentioned and negatively correlated with the wax content. In fact, cv. Early Bigi presented a high wax content and simultaneously a low cracking index. The stylar scar region cracks were the most prevalent in both cultivars. These results allowed us to conclude that, in the North Portugal region, the Lapins cherries presented better quality attributes than the Early Bigi cherries. However, the latter are still very valuable to the region due to its early ripening. Additionally, it was also possible to conclude that bigger, firmer, more mature, and with lower wax content cherries were more sensitive to cracking than the smaller fruits, soft-fleshed, less mature, and with higher wax content.<\/jats:p>","DOI":"10.3390\/plants9111557","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T20:17:52Z","timestamp":1605212272000},"page":"1557","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Cracking in Sweet Cherry Cultivars Early Bigi and Lapins: Correlation with Quality Attributes"],"prefix":"10.3390","volume":"9","author":[{"given":"Sandra","family":"Pereira","sequence":"first","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3269-1227","authenticated-orcid":false,"given":"V\u00e2nia","family":"Silva","sequence":"additional","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"given":"Eunice","family":"Bacelar","sequence":"additional","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"given":"Francisco","family":"Guedes","sequence":"additional","affiliation":[{"name":"Cermouros\u2014Cerejas de S\u00e3o Martinho de Mouros, Lda, Quinta da Ribeira, Bulhos, 4660-210 Resende, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7231-7021","authenticated-orcid":false,"given":"Ana Paula","family":"Silva","sequence":"additional","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"given":"Carlos","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Department of Agronomy, University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]},{"given":"Berta","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Quinta de Prados, 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1016\/j.scienta.2009.07.012","article-title":"Flavonol and phenolic acid composition of sweet cherries (cv.
