“…Among the 19 European plum cvs studied, the TPs–serving varied 3.7-fold (64.5–238.8 mg/100 g FW), and higher values were found in ‘Tuleu Dulce’, ‘BlueFre’, and ‘Asvestochoriou’, with the lowest in ‘Mpardaki Elliptic’, ‘Mpardaki circular’, and ‘Avgato’ Skopelou’ ( Table 2 ; Figure 3 ). The local cvs ‘Skopelou’ and ‘Ksina Skopelou’ were also in the highest range of TPs–serving, and similar mean values were previously recorded [ 12 ].…”

“…Considering the significant impact of plum on human nutrition, it is of interest to consumers to define cvs with high polyphenolic content. There is high variability reported in the phytochemical and antioxidative compositions among different European [ 3 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] and Japanese plum cvs [ 16 , 17 , 18 ]. However, the above studies were conducted separately and little is known about the differences between those two widely cultivated species.…”

Herein, we studied the variation in leaf and fruit morphological traits and antioxidant contents in 43 local and foreign cultivars (cvs) grown under the same experimental conditions in the widely cultivated plum species Prunus domestica and Prunus salicina. The peel contribution of fruit bioactive compounds in a serving portion, correlations among the examined parameters, and group patterns in each plum species were also studied. The species and cvs were sufficiently separated. Compared to Japanese cvs, European cvs had less elongated leaves and smaller and sweeter fruit with less total phenol and antioxidant capacities. The Japanese cvs ‘Red ace’ and the widely grown ‘Black Amber’, together with the European ‘Tuleu Dulce’, ‘BlueFre’, and the landrace ‘Asvestochoriou’ make up groups with rich dietary sources of phytochemicals. The peel tissue contained higher total phenols and antioxidant capacities compared to the flesh, while the peel/flesh ratios varied widely among the cvs (6.6-fold). The variation in the antioxidant contents was lower among the cvs calculated per serving portion (3.7-fold); yet the peel tissue contribution was equal to that of the flesh (48.6%), signifying its high nutritive value. We observed increased sweetness in the fruit in the later-harvested cultivars, while cvs with more blue- and red-colored peel generally contained higher antioxidant contents mainly in the European plums. Moreover, larger fruit sizes were positively correlated with larger and more elliptic leaf shapes. In conclusion, the significant role of the genotype and the peel tissue as a source of bioactive compounds in plums were outlined with prospects of utilization in future breeding programs.
