Special Issue Information

Dear Colleagues,

The genus Prunus is considered one of the most economically and agronomically important plant genera in temperate regions since it comprises species that are broadly cultivated for their edible fruits. This fact implies the existence of many breeding programs worldwide that are realizing new cultivars every year, but rootstocks are few and not produced a new one every year because of the larger process selection compared with the cultivar process selection. The correct identification of a rootstock × cultivar combination is one of many key requirements in activities associated with orchard production and management, making fruit arboriculture more economically and ecologically sustainable. Therefore, the continuous improvement of cultivars must be linked with rootstocks that confer the best characteristics through actions such as improving cultivar adaptability to different soil types and climatic conditions, improving fruit quality performance, adding tolerance/resistance to different abiotic and biotic stresses, improving rootstock × cultivar graft compatibility and inducing precocity and improving productivity with the adoption of different size-controlling rootstocks. Since there are many different factors that affect peach orchard profitability, it is necessary to conduct long-term studies to find the best rootstock × cultivar combination within the constraints imposed by local climate and economic conditions. However, because of the expense and time commitment required, there are not enough studies that offer direct long-term comparisons of different and new cultivars grafted on several rootstocks under similar or different climatic and soil conditions and abiotic/biotic stresses. The objective of this Special Issue is to provide a forum for new research and review articles on recent advances in Prunus species. Therefore, contributions to this SI may focus on (but need not be limited to) six major topics: (1) agronomy; (2) physiology; (3) fruit quality; (4) antioxidant properties; (5) postharvest; (6) molecular breeding.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

In the last years, an important renewal of plant material from different breeding programs is taking place in apricot in order to improve resistance to biotic stresses, extension of the harvest season, fruit quality, and productivity. However, the graft compatibility of many of these cultivars with most popular Prunus rootstocks is unknown, and this is an essential agronomical trait for their better performance and longevity. Hence, the introduction of new cultivars requires knowledge of the extent and nature of incompatibility reactions before releasing these cultivars on the market. In this study, the determination of graft compatibility was carried out in 13 new apricot cultivars grafted on four Prunus rootstocks: ‘Marianna2624’ (P. cerasifera × P. musoniana), ‘Miragreen’ (P. cerasifera × P. davidiana), ‘Mirared’ (P. cerasifera × Nemared), and ‘Montclar’ (P. persica L. seedlings) at early stages of development. By combining cytomorphological, anatomical, and phenylalanine ammonia-lyase (PAL) gene expression analysis at the graft interface, as well as different vegetative parameters, the results highlighted ‘Miragreen’ and ‘Mirared’ as promising rootstocks for apricot, showing the highest degree of compatibility with more than 90% of the apricot cultivars. These results provide useful information for breeders and growers by selecting the most suitable scion-rootstock for efficient orchard design by planting compatible graft combinations. Full article

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. Full article
