“…Among organic acids, malic acid was the most abundant, followed by citric acid, while the lowest amount was found for fumaric acid. This does not agree with the results reported by Drkenda et al (2019) or by Usenik et al (2007Usenik et al ( , 2013, who did not detect citric acid in European plum cultivars. Individual acid contents in 'Mrkosljiva' plum varied in the following ranges: malic acid 16.8-25.5 g kg -1 FW; citric acid 2.94-6.90 g kg -1 FW; shikimic acid 0.07-0.76 g kg -1 FW; and fumaric acid 0.03-0.07 g kg -1 FW.…”

“…However, fruits from 2009 and 2010 had a statistically higher fruit flesh percentage. Similar results relating to fruit weight and fruit flesh percentage were obtained for the native plum 'Pozegaca' (Drkenda et al 2019).…”

“…Generally, individual sugar content in 'Mrkosljiva' plum varied within the following ranges: glucose 45.6-57.4 g kg -1 FW, sorbitol 41.6-80.7 g kg -1 FW, sucrose 33.9-37.6 g kg -1 FW and fructose 12.3-21.7 g kg -1 FW. The Different letters ("a-c") in columns indicate significant differences between growing seasons at p ≤ 0.05 sorbitol level obtained is higher than previously found in the native plum 'Pozegaca' (Drkenda et al 2019). Plum fruits from 2010 and 2011 displayed a significantly higher content of total sugars compared to fruits from 2009.…”

“…Modern plum production in B&H is based on the cultivation of commercial plum varieties that are tolerant to plum pox virus (PPV). In addition to commercial genotypes, various autochthonous plum genotypes such as 'Pozegaca', 'Turgulja', 'Sisaca', and 'Mrkosljiva' among others can also be found (Drkenda et al 2014(Drkenda et al , 2019Halapija Kazija et al 2014;Drkenda and Kurtovic 2012). Sharka (PPV) is one of the most dangerous viruses in plum cultivation.…”

“…Traditional and autochthonous fruit genotypes are rich in various phenolic compounds (Begić-Akagić et al 2011;Akagić et al 2019;Drkenda et al 2019;Ðurić et al 2015;Balik et al 2019). Schmitz-Eiberger and Blanke (2012) reported that food producers and consumers are showing increasing interest in phenolic compounds as health-promoting substances.…”

The self-rooted plum genotype ‘Mrkosljiva’ was first selected as it was devoid of Sharka leaf symptoms during the 5‑year study (2009–2014), which was subsequently confirmed by negative ELISA test results. Hence, the aim of the study was to investigate the biochemical variability of the autochthonous ‘Mrkosljiva’ plum genotype, based on its sugar, acid and phenolic compounds content during 3 years. In 2010 and 2011, the plums tasted sweet with favourable sugar:acid ratios of 55:1 to 65:1. These plum fruits were collected at the full ripeness stage from an extensive orchard located in northeastern Bosnia and Herzegovina (45 °N). Analysis by HPLC identified the following polyphenolic compounds—chlorogenic acid, cyanidin-3-O-glucoside, cyanidin-3-O-rutinoside, neochlorogenic acid, quercetin-3-O-galactoside and quercetin-3-O-rutinoside—in all 3 years that were evaluated (2009–2011), but in different amounts, depending on the environmental conditions of each year. In 2009, the plums were healthier with a threefold greater phenol content than during the other 2 years of growth. In 2009, protocatechuic acid was detected, whereas catechin, procyanidin B1, procyanidin B2 and quercetin-3‑O-rhamnoside were not detected. The combination of high phenol and sugar content in ‘Mrkosljiva’ provides healthy and tasty plums suitable primarily for processing, and to a lesser extent, due to their size, for fresh fruit marketing.

Aim of study: To investigate the changes in chemical composition of fresh plum fruits cv. ‘Čačanska Lepotica’ prompted by the presence of various strains of plum pox virus (PPV). Area of study: Serbia Material and methods: In an experimental orchard of ‘Čačanska Lepotica’ plum cultivar, fruits were picked from virus-free and PPV-infected trees (PPV-D and PPV-Rec strains) in four harvest stages in 2017 and 2018. Fruits were further analyzed on total phenolics, flavonoids, anthocyanins, antioxidant capacity and selected phenolics. Main results: The results indicate that virus infection causes chemical changes to a certain extent, but mostly in initial harvest stages, while the values are equal in later stages. In the last harvest stage, as the most utilizable in commercial purposes, only chlorogenic acid content was affected in 2017, while in 2018 contents of neochlorogenic acid and chrysanthemin were altered by the PPV infection. Total contents of flavonoids and phenolics revealed no influence of virus infection during both 2017 and 2018, while PPV-Rec infected samples were richer in anthocyanins under heavy rainfall during summer months of 2018. Given the number of identified compounds (10) and the vast experimental data, it might be concluded that influence of PPV infection on chemical composition of ‘Čačanska Lepotica’ plum fruits was quite limited. Research highlights: Plum cultivar ‘Čačanska Lepotica’ should be considered as highly tolerant cultivar to PPV, and can be grown in heavily infected environment with no risk. Therefore, it might be a great replacement for sensitive plum cultivars, such as ‘Požegača’ and ‘Čačanska Rodna’.
