Sweet cherry research world overview 2015-2017

Abstract

This review contains 208 citation items from 31 countries in total. The highest number of citations come from Spain (34) then from the USA (23), Italy (18) and China (16). Only one citation comes from Denmark, Georgia, Macedonia, and New Zealand. They are all included into 16 topics arranged in alphabetical order. The results or conclusions of each study are briefly described and arranged according to the year of the publication and alphabetical order of the authors. The most important topic was the physiological research containing 40 citations and then the evaluation of cultivars containing 33 citations. From the years of the review, the most important was 2017 with 122 items, whereas the least prolific year was 2015 containing only 35 items.

Sweet Cherry (Prunus avium L.) Cracking during Development on the Tree and at Harvest: The Impact of Methyl Jasmonate on Four Different Growing Seasons

“…Among the cultivars, 'Prime Giant' exhibited the highest incidence of cracking on the tree compared to the other cultivars, such as the 'Staccato' and 'Sweetheart' cultivars, which displayed the lowest incidence of fruit cracking under ambient uncontrolled conditions (Figure 1A,B). The factors contributing to the differential tolerance among the cultivars remain unknown, but rain cracking, as a localized phenomenon, has a significant impact on fruit cracking [25,26]. In this sense, the 'Sweetheart' and 'Staccato' cultivars were not exposed to heavy rainfall since it is not common to have significant rainfalls towards the end of July, which is the typical harvesting time for these cultivars in the southeast of Spain.…”

Genetic and Hormonal Regulation of Sweet Cherry (Prunus avium L.) Maturity across Altitudinal Gradients

“…BA is used, as well as an effective thinning compound, for many crops like apples [19]. The pre-harvest treatment of Benzyl adenine combined with gibberellin in sweet cherries resulted in larger and firmer fruits [20]. Benzyl Adenine is considered the main CK used in the micropropagation of horticultural fruits crops, through organogenesis and somatic embryogenesis.…”

Putrescine Increases Frost Tolerance and Effectively Mitigates Sweet Cherry (Prunus avium L.) Cracking: A Study of Four Different Growing Cycles

“…The factors contributing to the different cracking tolerance among cultivars are still not clear. However, it is worth noting that localized occurrences like rain cracking exert a notable influence on sweet cherry cracking [50,51]. Regarding this factor, the 'Sweetheart' cultivar was not coincident with substantial rainfall between 2020 and 2022, as it is atypical for significant precipitation to occur across the month of July, which is the usual harvest time for this cultivar.…”

“…Fruit cracking is a multifactorial event, and for this reason, it is very difficult to determine the specific reasons affecting the different resistance levels among distinct cultivars [50]. However, rainfall emerges as a predominant factor in the complex equation of fruit cracking, with a clear effect related to the degree of fruit ripeness coinciding with rain events [6,52,53].…”
