“…Many peach cultivars of various peel and flesh color, flavor, and organoleptic quality are cultivated around the world to cover the market and consumer demand. Manganaris et al [3] highlighted the importance of cultivar breeding programs to focus on the consumer's acceptance and the selection of elite cultivars with enhanced aroma, with appreciable nutritional properties and extended market life. The 'Lemonato' peach is a Greek traditional series of clones with melting-flesh white-flesh peaches that is highly acceptable by consumers due to its distinct flavor, high nutritional value, and high total phenolic content [4,5].…”

‘Lemonato’ is a Greek peach melting-flesh white-flesh cultivar with high nutritional value highly appreciated by the consumers. This study aimed to evaluate the effect of pre-harvest foliar calcium application on fruit quality, primary metabolite profile, antioxidant activity, total phenolic content, and phenolic profile of the ‘Lemonato’ peach, clone ‘Stamatis’. The experiment was conducted for two years, 2019 and 2020, in two commercial orchards at Kato Lehonia and Agios Vlasios regions, central Greece, where the ‘Lemonato’ clone ‘Stamatis’ is traditionally cultivated. The treatments were organic calcium (Ca), calcium–silicate in nanoparticles (Ca–Si), and calcium chloride (CaCl2). Foliar application of the different Ca formulations, commonly used as a horticultural practice, were not effective at improving the fruit quality characteristics in this clone, which is characterized by fruit softening during ripening. The study revealed the sugars and organic acid composition and phenolic profile of the ‘Lemonato’ peach, clone ‘Stamatis’. Peach fruit quality, primary metabolites, and phenolic compounds of the two orchards showed a different response to organic Ca and Ca–Si, indicating that genetic or environmental factors may also be involved. A higher concentration of organic Ca and CaCl2 increased the peach fruit phenolic compounds content and the total antioxidant activity, improving the fruit nutritional quality.

“…However, a descending trend has been registered over the recent years in several key peach-producing countries, and the increase of salt concentration in the cultivated land is one of the reasons that restrict the development of peach industry. 18 Salinity stress is one of the dominant abiotic stress factors that limit industrial crop growth and productivity and threaten agricultural security, 19 responding to salt stress as the main organ of plants to sense salt stress signals. 20 Current transcriptome and metabolome analyses of plant resistance to abiotic stresses are mostly performed in plant leaves.…”

Soil salinity is a major conlinet limiting sustainable agricultural development in peach tree industry. In this study, lipid metabolomic pathway analysis indicated that phosphatidic acid is essential for root resistance to salt stress in peach seedlings. Through functional annotation analysis of differentially expressed genes in transcriptomics, we found that MAPK signaling pathway is closely related to peach tree resistance to salt stress, wherein PpMPK6 expression is significantly upregulated. Under salt conditions, the OE-PpMPK6 Arabidopsis thaliana (L.) Heynh. line showed higher resistance to salt stress than WT and KO-AtMPK6 lines. Furthermore, we found that the Na+ content in OE-PpMPK6 roots was significantly lower than that in WT and KO-AtMPK6 roots, indicating that phosphatidic acid combined with PpMPK6 activated the SOS1 (salt-overly-sensitive 1) protein to enhance Na+ efflux, thus alleviating the damage caused by NaCl in roots; these findings provide insight into the salt stress-associated transcriptional regulation.

“…The peach, belonging to the family Rosaceae and the genus Amygdalus L., is an important deciduous fruit tree in China and one of the fruit trees with the largest cultivation areas and the highest yields in the world [ 1 ]. Root system management is the core of the management of fruit tree cultivation, and is the key to achieving high quality and high yield through rational root system management.…”

The oxygen content in the root zone considerably affects the growth and development of peach trees. However, few studies have been conducted on the effects of the oxygen content in the root zones of peach trees on soil microbes and root growth. Four-year-old Ruiguang 33/Prunus persica (L.) Batsch trees were used to study the effects of root-zone aeration on soil microbes in a peach orchard, as well as on the soil nutrient contents, peach tree root systems, and plant potassium-to-nitrogen ratios. The results showed that the root-zone aeration substantially increased the soil oxygen content in the root zone and changed the soil microbial community structure. Compared with the control, the relative abundances of soil nitrogen-fixing microorganisms (Beta proteobacteria and Bradyrhizobium elkanii) and potassium-solubilizing microorganisms (Bacillus circulans) under the root-zone aeration conditions were greatly enhanced. Root-zone aeration increased the soil’s alkaline nitrogen content, available potassium content, and organic matter content, as well as the number and thickness of new white roots of peach trees, and root activity was increased significantly. At the same time, root-zone aeration changed the relative contents of total potassium and total nitrogen in the plants and considerably increased the potassium–nitrogen ratio in the shoots. The results indicate that aeration in the root zone can change the soil microbial community structure, increase the abundances of nitrogen-fixing and potassium-solubilizing microorganisms, and increase the plant potassium-to-nitrogen ratio, which are conducive to peach fruit quality.
