“…Other factors, such as habitat type, microclimatic conditions, vegetation density and underlying genetic diversity of the populations are likely to play a role in the phenotypic diversity of European wild pear populations and require further research. Similar results were also confirmed for other woody species: Alnus incana [ 46 ], Fraxinus angustifolia Vahl [ 82 ], Pyrus spinosa [ 65 ], Rubus idaeus L. [ 83 ] and Quercus acutissima Carruth. [ 84 ], showing a unifying trend, most likely arising from a shared ability to adjust to local environments, in order to survive.…”

Leaves play a central role in plant fitness, allowing efficient light capture, gas exchange and thermoregulation, ensuring optimal growing conditions for the plant. Phenotypic variability in leaf shape and size has been linked to environmental heterogeneity and habitat characteristics. Therefore, the study of foliar morphology in plant populations can help us to identify the environmental factors that may have influenced the process of species diversification. In this study, we used European wild pear (Pyrus pyraster (L.) Burgsd., Rosaceae) as a model species to investigate the phenotypic variability of leaves under different environmental conditions. Using leaf morphometric data from 19 natural populations from the north-western part of the Balkan Peninsula, a high level of variability among and within populations were found. Leaf traits related to leaf size were more variable compared to leaf shape traits, with both influenced by geographic and environmental factors. Consequently, patterns of isolation by environment (IBE) and distance (IBD) were identified, with IBE showing a stronger influence on leaf variability. Multivariate statistical analysis revealed that European wild pear populations from the north-western part of the Balkan Peninsula can be divided into two morphological clusters, consistent with their geographical distance and environmental conditions. Our results confirm a high level of phenotypic variability in European wild pear populations, providing additional data on this poorly studied species, emphasizing phenotypic plasticity as a major driver in the adaptation of this noble hardwood species to rapid climate change.

Red raspberry is a kind of fruit with high nutritional values. To evaluate the comprehensive quality of 24 red raspberry varieties in Northeast China, physicochemical properties, bioactive compounds and sensory characteristics were measured, followed by principal component analysis (PCA) and cluster analysis (CA). Altogether, eight important property indexes for processing attributes were selected out using PCA, including titratable acidity (TAC), sugar-acid ratio (SAR), pH, length, diameter, weight, sucrose and citric acid. Six individual sugars, including l-rhamnose monohydrate, fructose, glucose, sucrose, maltose and d-trehalose anhydrous, as well as eight organic acids, including oxalic acid, tartaric acid, malic acid, α-ketoglutaric acid, lactic acid, citric acid, fumaric acid and succinic acid, were identified in red raspberry. The two main clusters according to individual sugar, organic acids and SAR indicated that varieties including ‘European red’, ‘DNS9’, ‘Bulgaskc’, ‘Canby’ and ‘Samodiva’ were suitable for fresh-eating or processing to juice or other products directly because they had suitable SAR; other varieties with relatively low SAR were unsuitable for fresh-eating and need to adjust their excessive sour taste during processing.

“…These regions are characterized by having mountains, streams, rivers, and some roads that can act as corridors that determine the behavior and genetic differentiation within the groups or species evaluated (GARRIDO-GARDUÑO; VAZQUEZ-DOMINGUEZ, 2013). VELJKOVIĆ et al (2019), mentions that in the genus Rubus, altitude plays an important role in the genetic separation of the populations of raspberries (R. idaeus). It should also be taken into consideration that the species of the genus Rubus are characterized by having a taxa with a wide and successful distribution and can be found in different parts of the world and present morphologically different individuals.…”

Colombia is home to blackberry genetic resources which present a morphological diversity. The relevant characteristics related to its diversity are the presence of prickles, the shape of its leaves, the number and color of its fruits, and its enormous agro-industrial potential due bioactive compounds such as polyphenols. These plants can grow between 1,700 and 3,400 m asl and are cultivated in the central region of the country. The study evaluated 13 wild and cultivated plants from the genus Rubus. A molecular characterization was carried out using 16 SSR microsatellite markers, all of which produced positive amplification generating 23 loci and 26 alleles. The AMOVA indicated a molecular genetic differentiation of 23% between the groups which corresponded to the geographic location of the sample. The greatest contribution to variance is found within the groups (76%), possibly because each of them is composed of different cultivated species and wild relatives of the genus Rubus. This suggests that the grouping of the genotypes studied doesn’t necessarily correspond to geographical origin. However, the findings show high genetic variation, with an Fst value of 0.27. This may be useful in breeding programs where genetic diversity, morphological characteristics of the fruits, and the molecular identification of the fruits are taken into account.
