Sweet Cherry Cultivars

Sweet cherry has many cultivars with different storability and nutritional properties. To reveal the reasons for the differences in storability among cultivars and improve the quality of sweet cherries, the surface microstructure of four representative sweet cherry cultivars (Red Light, Ranier, Red Agate, Friendship) epidermis and peduncle at harvest were examined and the effects of carboxymethyl chitosan-gelatin (CMCS-GL) based edible coating incorporating CaCl2 and ascorbic acid (AA) (AA-CaCl2-CMCS-GL) on the quality and nutritional characteristics of sweet cherry were evaluated. Results showed there were significant differences in the wax distribution of the epidermis and the number of stomata on the peduncle surface between four cultivars of sweet cherries at harvest, which was closely related to fruit decay ratio during storage. AA-CaCl2-CMCS-GL coating delayed the onset of decay and the fruit decay ratio in coated groups (3.0%–15.3%) was significantly lower than in control groups (17.7%–63.0%) after 33 d storage. The coating also helped to maintain the quality and nutritional characteristics of four sweet cherry cultivars, including reducing weight loss, maintaining better skin color, peduncle freshness, higher fruit firmness, titratable acidity, AA, total phenolics content, total anthocyanins concentration, and antioxidant capacity. These results suggested that AA-CaCl2-CMCS-GL coating could be considered as a new preservation method for improving postharvest quality and nutritional properties of different sweet cherry cultivars.

The aim of this study was to evaluate and compare the content of a number of bioactive compounds and antioxidant activity of fruits of selected local and commercial sweet cherry (Prunus avium L.) cultivars. The experiment showed that the selected cultivars of sweet cherries differ significantly in the content of polyphenolic compounds and carotenoids. The fruits of commercial sweet cherry cultivars were, on average, richer in polyphenols (the sum of phenolic compounds determined chromatographically), flavonoids, as well as anthocyanins and were characterized by higher antioxidant activity when compared to the local, traditional cultivars. In the group of the traditional sweet cherry cultivars, particular attention could be paid to Black Late cv., showing the highest antioxidant activity of fruits. In the group of commercial sweet cherry cultivars, Cordia and Sylvia fruits could be recognized as being rich in bioactive compounds with high antioxidant activity. Yellow skin cultivars were characterized by the highest concentrations of carotenoids. Strong positive correlations between the identified bioactive compounds and antioxidant activity of fruits were also found. Although different cultivars of sweet cherries show a high variability in phenolics and carotenoids profiles as well as in the antioxidant activity of fruits, they all should be, similarly to other types of cherries, recognized as a rich source of bioactive compounds with an antioxidant potential.

Sweet Cherry Cultivars

Bacterial canker of sweet cherries in the Niagara Peninsula of Ontario is caused by at least two species or physiotypes of Pseudomonas bacteria. Biochemical tests indicated that the species are similar to English isolates of P. morsprunorum Wormald and P. syringae van Hall. Pathogenicity tests on nine sweet cherry cultivars and on seedlings of apple, pear, peach and mahaleb and mazzard cherry indicated that Ontario P. morsprunorum and P. syringae isolates are pathogenically distinct. Comparative tests with English and Ontario isolates indicated close pathogenic similarities among isolates of P. morsprunorum, whereas isolates of P. syringae appeared to be distinct races. Susceptibility trials with sweet cherry indicated that Ontario grown cultivars are sufficiently sensitive to both bacterial species to consider the disease a serious problem in cherry production. Moreover, the existence of at least two pseudomonas species in Ontario with distinct pathogenicity patterns in sweet cherry indicates that breeding for resistance will be a difficult task.

Postharvest Treatment

Sweet cherry shows a limited storage time mainly due to incidence of decay and a fast loss of sensory quality of the fruit. Sweet cherries may be damaged seriously by fungal pathogens for a long storage period. For the control of postharvest diseases, the use of chemicals as fungicides has been applied to sweet cherries. In this paper, a kind of antimicrobial packaging, based on our patent , which can release SO2fungicide has been used as postharvest treatment to protect the sweet cherry quality. Cherries quality during storage was determined, and results suggest that SO2 fungicide packaging showed benefits in terms of lower weight loss, lowerSuperscript textdecay rate and maintenance of fruit firmness compared with the control one.

A recently developed technique was used to determine the susceptibility to fruit surface pitting of new sweet cherry (Prunus avium L.) cultivars and compare them to an industry standard. The cultivars tested included Bing (industry standard), Cristalina, Lapins, Sandra Rose, Santina, Skeena, Sonata, Staccato, and Sweetheart. Fruit were harvested at commercial maturity, injured, held at 1°C for 2 wk and then rated for fruit surface pitting. The cultivars Lapins, Skeena, Staccato, and Sweetheart had less pitting than Bing. Cristalina and Sonata tended to have similar levels of injury to Bing and Sandra Rose and Santina tended to have more severe pitting than Bing. Key words: Sweet cherries, cultivars, simulated pitting injury

During the cold storage of sweet cherry, severe losses can occur due to the water loss, phytopathogenic fungi and physiological disorders. The aim of this research was to assess the effects of treatments with NAA (α-naphthaleneacetic acid), BA (6-benzyladenine), and GA3 (gibberellic acid) on fruit quality at harvest and after 21 days of storage under two regimes, including 0°C, RH (relative humidity) 90% and 3°C, RH 70%, and after additional shelf life exposure. Sweet cherry cultivars – ‘Summit’, ‘Kordia’ and ‘Regina’ – were treated with bioregulators at the end of flowering. NAA significantly increased the fruit weight at harvest compared to the control in all cultivars assessed. BA stimulated the fruit growth in ‘Kordia’ and ‘Regina’, while it was ineffective in ‘Summit’. GA3 caused significant increase in fruit weight by 8.3% in ‘Kordia’ only. Moreover, BA and GA3 induced a higher firmness of fruits at harvest. Weight loss of fruits during storage at 0°C, RH 90%, was increased with NAA and reduced with GA3 in ‘Regina’ only. BA and GA3 reduced the weight loss of sweet cherry fruits stored at 3°C, RH 70%. Bioregulator treatments increased TA (titratable acidity) in fruits at harvest, while the effects on TA during storage were variable depending on the cultivar. ‘Summit’ had the highest sensitivity to storage fruit rot. BA and GA3 decreased the disease occurrence on fruits stored at 0°C in ‘Summit’ and ‘Kordia’.

AbstractThe pollination of self-incompatible diploid sweet cherry is determined by the S-locus alleles. We resolved the S-alleles of 50 sweet cherry cultivars grown in Estonia and determined their incompatibility groups, which were previously unknown for most of the tested cultivars. We used consensus primers SI-19/20, SI-31/32, PaConsI, and PaConsII followed by allele-specific primers and sequencing to identify sweet cherry S-genotypes. Surprisingly, 48% (24/50) of the tested cultivars, including 17 Estonian cultivars, carry the rare S-allele S17, which had initially been described in wild sweet cherries in Belgium and Germany. The S17-allele in Estonian cultivars could originate from ‘Leningradskaya tchernaya’ (S6|S17), which has been extensively used in Estonian sweet cherry breeding. Four studied cultivars carrying S17 are partly self-compatible, whereas the other 20 cultivars with S17 have not been reported to be self-compatible. The recommended pollinator of seven self-incompatible sweet cherries is of the same S-genotype, including four with S17-allele, suggesting heritable reduced effectiveness of self-infertility. We classified the newly genotyped sweet cherry cultivars into 15 known incompatibility groups, and we proposed four new incompatibility groups, 64–67, for S-locus genotypes S3|S17, S4|S17, S5|S17, and S6|S17, respectively, which makes them excellent pollinators all across Europe. Alternatively, the frequency of S17 might be underestimated in Eastern European populations and some currently unidentified sweet cherry S-alleles might potentially be S17.

One-year-old shoots of 100 selected cherries representing the species Prunus avium (94 selections), P. fontanesiana, P. gondouini, and P. mahaleb were frozen at −35 °C, then forced in a growth chamber for 3 weeks, and visually examined for cold damage and recovery.The response of the better-known cultivars and species corresponded to their known hardiness. The hardiest seven cultivars or species included all six representatives of the species other than P. avium and one sweet cherry, the U.S. Department of Agriculture introduction Glenn Dale No. 6. The recorded differences in hardiness between sweet cherry cultivars were larger than expected. Certain numbered seedling selections were relatively hardy and may constitute a valuable source of breeding material.Bark, cambium, wood, supplemental buds, and primary leaf buds were examined for cold damage and recovery. Damage to primary leaf buds proved the most useful criterion for determining hardiness of cherry cultivars.

New Cultivars

Sweet cherries (Prunus avium L.) are highly appreciated fruits for their taste, color, nutritional value, and beneficial health effects. In this work, seven new cultivars of sweet cherry were investigated for their main quality traits and nutraceutical value. The phytochemical profile of three classes of phenolic compounds and the antioxidant activity of the new cultivars were investigated through high-performance liquid chromatography with diode array detection (HPLC-DAD) and spectrophotometric assays, respectively, and compared with those of commonly commercialized cultivars. Cyanidine-3-O-rutinoside was the main anthocyanin in all genotypes, and its levels in some new cultivars were about three-fold higher than in commercial ones. The ORAC-assayed antioxidant capacity was positively correlated with the total anthocyanin index. The nutraceutical value of the new cultivars was investigated in terms of antioxidant/neuroprotective capacity in neuron-like SH-SY5Y cells. Results demonstrated that the new cultivars were more effective in counteracting oxidative stress and were also able to upregulate brain-derived neurotrophic factor (BDNF), a pro-survival neurotrophin, suggesting their potential pleiotropic role in counteracting neurodegenerations.

This review article provides information on the main directions in assessing the economic and biological characteristics of sweet cherry cultivars and forms at the present stage. The problem of the need for the study of sweet cherry cultivars for winter hardiness, frost resistance, drought tolerance, resistance to fungal diseases (especially coccomycosis and moniliosis) is considered in detail. The rationale for the need for a continuous search for cherry genotypes, distinguished by self-fertility and high biochemical properties, is given. The article argues that it is necessary to continue research in the field of productivity of sweet cherry cultivars, since the order of fruit formation, fruiting features, and placement of sweet cherry productivity elements are not fully understood and often contradict each other. Information on achievements in breeding, cultivar research and economic and biological assessment of sweet cherry in domestic and foreign research institutions is provided.
