“…In contrast, Iglesias et al [15] reported a negative correlation between SSC and growing degree days (the difference between the daily mean temperature and a base temperature of 10 • C from full bloom date to harvest date). The low air temperature could play a role in an overall reduction in fruit size and sugar concentration [53]. Font i Forcada et al [14] reported that organic acids profile in fruits was negatively correlated with temperature factors for three years of evaluation, as happens in the present study for TA and five years.…”

Since there are many different factors which affect peach orchard profitability, it is necessary to conduct long-term studies to find the best scion/rootstock combination within the constraints imposed by local climate and economic conditions. The influence of six peach-almond hybrids (“Adafuel”, “Adarcias”, Garnem”, “GF 677”, “PADAC 9902-01” and “Rootpac 70”); one P. persica × P. davidiana hybrid: “Cadaman”; five hexaploid plums (“Adesoto 101”, “PM 44 AD”, “PM 105 AD”, “PM 150 AD”, and “Penta”); three plum × peach-almond hybrids (“PADAC 04-01”, “PADAC 04-03” and “PADAC 99-05”), and one plum x almond hybrid (“Rootpac R”) on agronomic, basic fruit quality parameters, and flower and leaf mineral nutrients of the “Big Top” nectarine was tested. The highest vigor was induced by “Adafuel”, while the lowest vigor was exhibited by “PM 105 AD”, although the latter did not differ from the rest of the rootstocks. Yield efficiency was higher for “Adesoto 101” and lower for “Adafuel”. Regarding the soluble solids content (SSC), “PADAC 04-01” rootstock induced the highest average content, although it did not differ from “Adarcias”, “Adesoto 101”, “PADAC 99-05”, “PM 105 AD”, and “Rootpac R”. In addition, significant effect of rootstock was found on the flower and leaf mineral analysis traits evaluated. The medium (“Adarcias”, “Adesoto 101”, “PM 105 AD”) to high vigorous plum based hybrid rootstocks (“PADAC 04-01”, “PADAC 99-05” and “Rootpac R”) showed the tendency to induce a better fruit quality, based on higher concentration of SSC, and other yield attributes, demonstrating their commercial interest as new rootstocks for peaches. Considering its overall performance, “PADAC 04-01” appears as a new promising rootstock alternative to peach-almond hybrids on heavy and calcareous textured soils.

“…Abdelghafar et al (2018) also found that the annual variation in the antioxidant composition was independent of season and peach germplasm. Environmental variables such as temperature, solar radiation, photoperiod, precipitation, and soil profile affect the growing environment and result in wide variations in peach fruit harvest quality (Lopresti et al, 2014). The effects of environment and orchard practices on peach fruit quality attributes are extensively reviewed by Minas et al (2018).…”

A sustainable approach to control the incidence of brown rot in pre-and post-harvest management is to select genotypes with high contents of antioxidant compounds and tolerance to Monilinia laxa (Aderh. and Ruhland) Honey. In this study, 68 progenies of the 'Babygold 9' × 'Crown Princess' population from the EEAD-CSIC breeding program were screened under controlled conditions for a period of 3 years (2013-2015). Susceptibility to brown rot was evaluated after inoculating 20 healthy fruits per genotype with M. laxa. Brown rot incidence, lesion diameter, and colonization extent, as well as the severities of these issues, were calculated after 5 days of incubation. Physicochemical traits, such as fruit firmness and soluble solids content, were also recorded before and after storage. Titratable acidity, pH, and antioxidant composition were measured at harvest. Significant differences were found for pathogenic traits, as well as for contents of vitamin C, total phenolics, flavonoids, and anthocyanins, within genotypes in this population. Negative correlations were also found between the content of phytochemical compounds (such as anthocyanins and total phenolics), as well as disease incidence and severity. Differences in susceptibility to brown rot confirm the genetic variability available in these progeny. This allowed the selection of six genotypes highly resistant to brown rot of M. laxa, with high organoleptic properties and high phenol content, to be introduced in our peach breeding program.

“…It is interesting to mention the significant negative correlation between SSC and the DD. Lopestri et al (2014) reported that low air temperature could play a role in an overall reduction in fruit size and sugar concentration. Bonora et al (2013) reported that riper, more exposed fruit harvested from the same trees did not have significantly higher SSC than shaded fruit.…”

This study aimed to evaluate the stability of 'Big Top' nectarine fruit quality (fruit weight, fruit mineral elements and fruit phytochemical composition such as soluble solids content, titratable acidity, individual sugars, individual organic acids, total ascorbic acid content, total phenolics content, and antioxidant capacity) when grafted on 20 Prunus rootstocks over two consecutive seasons. For most of the evaluated traits, rootstock was the main source of variability, whereas for Mg, malic and citric acids, and glucose most of the variability was observed among years. Similarly, the interaction year × rootstock was not significant for most traits (14 out of 21), hence highlighting that most rootstocks responded in a similar manner to changes in the weather conditions. Thus said, some important microand macro-nutrients such as Ca, Mg, Fe, Zn, together with taste-(fructose, glucose and sucrose) or health-related (antioxidant capacity) compounds showed a differential influence of the rootstock depending on the year conditions and thereby suggested that climatic conditions can be a limiting factor in the choice of rootstocks for a given nectarine cultivar.Overall, the results from this study indicated that the cherry-plum hybrid Krymsk-1 and the peach-plum hybrid PS rootstocks are the most suitable rootstocks for 'Big Top' under the conditions investigated herein. Both rootstocks induced high values on sugar profile, ascorbic acid, antioxidant activity, and TPC of 'Big Top' nectarine being relatively stable regardless of the weather conditions. Finally, the rootstocks IRTA-1 and Rootpac-20 also induced good fruit quality and phytochemical properties to 'Big Top' fruit.
