Determination of the pomological and nutritional properties of selected plum cultivars and minor fruit species

Abstract

This study included twenty-three samples of minor fruit species and twenty-three plum cultivars. First of all, the pomological properties of the plum cultivars were assessed, where the cultivar ‘Aphrodite’ was determined as the cultivar with the biggest fruits (56.6 g). The selected nutritional properties were subsequently determined in all forty-six samples. The highest value of the total soluble solids in the plums was 27.3 % in ‘Stanley’ (Prunus domestica) and 26.1 % in ‘Krasavica’ (Sorbus aucuparia) in the minor fruits; the highest total content of ascorbic acid in the plums was 83.3 mg/100 g in ‘Stanley’ (P. domestica) and 622.9 mg/100 g in ‘Krasavica’ (S. aucuparia) in the minor fruits; the highest total phenolic content in the plums was 429.8 mg GAE/100 g in ‘Fortune’ (Prunus salicina) and 45.3 mg GAE/100 g in the minor fruits and 983.9 mg GAE/100 g in ‘Vydubecký’ (Cornus mas); the highest total flavonoid content in the plums was 291.5 mg CE/100 g in ‘Fortune’ (P. salicina) and 544.7 mg CE/100 g in ‘Nero’ (Sorbus melanocarpa) in the minor fruits, and the highest total antioxidant activity in the plums was 809.5 mg TE/100 g in the hybrid ‘SLE2014/2’ (P. domestica × P. salicina) and 849.8 mg TE/100 g in ‘Amfora’ (Lonicera edulis) in the minor fruits.

Qualitative and Nutritional Characteristics of Plum Cultivars Grown on Different Rootstocks

“…Thus, in these cases, the sweet taste prevailed. Similarly, as in Wolf et al [3], the higher values of SSC were measured at European plum 'Stanley' than at Japanese cultivars and analyzed cultivars reached the highest values on different rootstock.…”

“…Trendafilova et al [32] studied quality of European plum ' Čačanska Lepotica' and TPC in their study for this cultivar on Ishtara rootstock was 93.7 mg (GAE)/100 g. The values for next four rootstocks were higher. The average value of TPC for cultivars grown on Ishtara rootstock was 562.75 mg (GAE)/100 g and the European cultivar 'Stanley' reached on Ishtara rootstock 407.42 mg (GAE)/100 g. Wolf et al (2020) [3] determined similar values of TPC ranging from 51.46 to 429.77 mg (GAE)/100 g.…”

“…Two species, European plum (P. domestica) and Japanese plum (P. salicina), are distinguished according to their origin and dominate the modern commercial production [2]. Plums differ often with their pomological and nutritional properties [3]. Both species are rich sources of energy due to their high content of sugars, mainly monosaccharides.…”

Exploring the potential of phenolic and antioxidant compounds in new Rosaceae fruits

“…Focusing only in Sorbus fruits, there also are some researchers who reported some results comparing different maturity stages, 89 different parts of the fruit, 90 different genotypes, 67,71 different harvesting dates, 91 and different locations, 92,93 all reporting values of the same range of magnitude as the results reported here.…”

Unlocking Plum Genetic Potential: Where Are We At?

“…Plums are highly appreciated by consumers for their attractiveness, contrasted taste and juiciness, the wide range of flavor intensity, aroma, texture, color, shape, and size [9][10][11][12], but also recently for their nutraceutic properties and high antioxidant content [13][14][15][16]. The nutritional properties of several European and Japanese cultivars are reported by Wolf et al [17]. Additionally, a recent systematic review on the health effects of plums showed that plum consumption is associated with improved cognitive function, bone health parameters and cardiovascular risk factors [18].…”
