“…For Drunk Incense, the skin color of grapes on the same bunch is relatively similar throughout the growth process, and the judgment error mainly occurs between Mc values of 0.8 and 0.9 [ 38 ]. For example, Ponce et al [ 39 ] also found that due to the different cherry fruit varieties, differences in the accumulation of anthocyanins during the fruit development process led to potential differences in fruit evolution, similar to the results of our study.…”

To predict grape maturity in solar greenhouses, a plant phenotype-monitoring platform (Phenofix, France) was used to obtain RGB images of grapes from expansion to maturity. Horizontal and longitudinal diameters, compactness, soluble solid content (SSC), titratable acid content, and the SSC/acid of grapes were measured and evaluated. The color values (R,G,B,H,S,and I) of the grape skin were determined and subjected to a back-propagation neural network algorithm (BPNN) to predict grape maturity. The results showed that the physical and chemical properties (PCP) of the three varieties of grapes changed significantly during the berry expansion stage and the color-changing maturity stage. According to the normalized rate of change of the PCP indicators, the ripening process of the three varieties of grapes could be divided into two stages: an immature stage (maturity coefficient Mc<0.7) and a mature stage (after which color changes occurred) (0.7≤Mc<1). When predicting grape maturity based on the R,G,B,H,I,and S color values, the R,G,and I as well as G,H,and I performed well for Drunk Incense, Muscat Hamburg, and Xiang Yue grape maturity prediction. The GPI ranked in the top three (up to 0.87) when the above indicators were used in combination with BPNN to predict the grape Mc by single-factor and combined-factor analysis. The results showed that the prediction accuracy (RG and HI) of the two-factor combination was better for Drunk Incense, Muscat Hamburg, and Xiang Yue grapes (with recognition accuracies of 79.3%, 78.2%, and 79.4%, respectively), and all of the predictive values were higher than those of the single-factor predictions. Using a confusion matrix to compare the accuracy of the Mc’s predictive ability under the two-factor combination method, the prediction accuracies were in the following order: Xiang Yue (88%) > Muscat Hamburg (81.3%) > Drunk Incense (76%). The results of this study provide an effective way to predict the ripeness of grapes in the greenhouse.

“…Therefore, this difference between IAD results and the CTIFL color chart is most likely due to differential levels of compounds other than the anthocyanins. Recently we have reported a difference in the phenolic accumulation dynamics between non-anthocyanin phenols and anthocyanins during sweet cherry fruit development in these two cultivars [33].…”

Canopy Spraying of Abscisic Acid to Improve Fruit Quality of Different Sweet Cherry Cultivars

Abscisic acid (ABA) plays a major role in promoting ripening in sweet cherry, a non-climacteric fruit. Exogenous application of ABA has been performed to study fruit ripening and cracking, but this growth regulator is not used for commercial production. To determine the potential of this growth regulator to improve sweet cherry fruit quality, ABA canopy spraying was assayed in four cultivars. Canopy spraying of S-ABA significantly: (1) enhanced sweet cherry fruit color in ‘Glenred’, ‘Lapins’ and ‘Bing’ cultivars, but not in ‘Royal Rainier’ (a bi-colored cultivar), and (2) decreased fruit size and firmness in ‘Lapins’, ‘Bing’ and ‘Royal Rainier’. Seasonally reproducible effects were seen in ‘Lapins’ (mid/late-maturing) but not in ‘Glenred’ (early-maturing). Canopy spraying of nordihydroguaiaretic acid (NDGA) decreased color and increased fruit size in ‘Lapins’, but not in ‘Glenred’. Direct application of ABA on fruits attached to the tree, without application to the foliage, increased ‘Lapins’ fruit color without reducing size. These results suggest a localized fruit response to exogenous ABA application on fruit color development, but that a decrease in fruit size may be due to the effects of exogenous ABA on the tree canopy foliage.

“…In sweet cherry, though, a small respiratory peak occurs from the de-greening to the pink color initiation stage (Zhao et al, 2013). Variations in compounds that characterize sweet cherry fruits are the decrease in some phenolics and flavonols during development; and the increase in the anthocyanin concentration at the pink or red stages (Teribia et al, 2016; Ponce et al, 2021). This increase occurs simultaneously or soon after ABA accumulation (Ponce et al, 2021).…”

Abscisic acid (ABA) plays a key role in the ripening process of non-climacteric fruits, triggering pigment production, fruit softening, and sugar accumulation. Transcriptomic studies show that ABA modifies the expression of several ripening-related genes, but to date, the epigenetic approach has not been utilized to characterize the role of ABA during this process. Therefore, this work aimed to perform transcriptomic and DNA methylation analyses of fruit samples treated with ABA during the fruit ripening process in the non-climacteric sweet cherry model. RNA-seq analyses revealed an overrepresentation of transcripts annotated in functional categories related to ABA response, secondary metabolism, and sugar synthesis. In contrast, Whole Genome Bisulfite Sequencing (WGBS) revealed DNA hypomethylation in the 5′UTR region of genes related to carotene catabolism. Genes encoding xyloglucan enzymes were regulated transcriptionally and epigenetically during ripening. ABA treatment enhanced color development and ripening. GO analysis of DEGs in the RNA-seq of the ABA treatment revealed expression variations in genes encoding members of the Aux/IAA and ARF families. In the WGBS, genes encoding enzymes of the cytokinin biosynthesis had differential DNA methylation after the ABA treatment. Our work shows the genetic factors modulated by ABA at the genetic and epigenetic levels during non-climacteric ripening.
