‘Žutica’ is the most widespread olive variety of Montenegro, accounting for as much as 98% of olive trees in the southern part of Montenegrin coastal area – Bar subarea. The primary purpose of variety ‘Žutica’ is olive oil production due to its small fruits and high oil content, although it is also much appreciated as a table olive, prepared in local ways as green and black. As ‘Žutica’ is an old olive variety there are some phenotypic differences recorded in the fruit properties. Here we evaluated 22 accessions from the area of Bar and Ulcinj, where this variety is very widespread (almost mono-varietal), for 34 parameters of the fruit and endocarp. Significant differences in fruit properties were observed in the accessions. Average fruit size in nine accessions was above 3.5 g and in two accessions more than 4.0 g. Number of fruits per kg ranged from 224 to 330. Cluster analysis and principal component analysis (PCA) were used to group the accessions and evaluate the morphological variability. The accessions clustered into two groups, with two off group accessions of the highest fruit weight. The results showed differences among individuals, especially for large fruit accessions that should be investigated further.

Cornelian cherry is a little-known plant that can be grown in Poland both on a commercial and amateur scale. The commercial cornelian cherry plantations should be established using selected cultivars or vegetatively propagated valuable ecotypes, as only this guarantees a uniform yield, maturation and standardization of fruit quality. The experiment was carried out in 2014 and 2015 in the private plantation of cornelian cherry (Cornus mas L.) located in Dąbrowica, near Lublin (22.454 N; 51.270 E). The subject of the research were ecotypes No.: 1, 2, 3, 4, 5, 6, 7, 10, 11, 14, 15 obtained as seedlings in 1998. Cornelian cherry plants obtained from seeds differed very much in the yield and quality of fruit. The fruit characteristics for the examined ecotypes ranged to 1.63–2.21g for fruit weight, 1.30–1.61 for fruit shape index, 10.13–15.32% for content of stone, 17.85–22.68% for soluble solids content (SSC), 2.32–3.0% for titratable acidity (TA), 6.59–8.36 for SSC/TA, 54.9–75.97 for vitamin C content. Among the ecotypes studied in terms of external fruit features, ecotypes No. 3 and 4 were distinguished due to the largest fruits (mass and diameter) and relatively small share of the stone in the whole mass of the fruit. However, due to the chemical composition, the fruits of ecotype No. 5 were distinguished by the content of extract, extract to acids ratio, sugar, dry matter, anthocyanins and vitamin C content. These fruits enjoyed 55% strong acceptability among adults. The indicated ecotypes can be used in breeding as well as in nursery for obtaining valuable varieties of cornelian cherry for production in Poland.

In this research, we examined some of the physical (fruit dimensions, geometric mean diameter sphericity and surface area) and mechanical (puncture force, deformation, energy absorption and hardness) properties on the four different domestic (Şebin, Kaman, Bilecik and Yalova-3) and two different foreign (Chandler and Fernor) walnut (Juglans regia) varieties. For this purpose, we applied puncture force on the walnuts at the direction of width orientation (x–x), length orientation (y–y) and suture orientation (z-z). According to obtained results, there are significant differences among the walnut varieties for crustacean walnut weight and walnut weight. The maximum and minimum values of crustacean walnut weight were observed as 18.27 g and 10.98 g for Kaman and Chandler, respectively. In addition to these results, Bilecik has a maximum walnut weight – 8.71 g, while the minimum walnut weight was observed for Yalova-3 – 4.57 g. Furthermore, geometric mean diameter and sphericity values ranged to 31.93–38.57 mm and 82.78–92.54%, respectively. There are statistically significant differences on the puncture force, deformation, energy absorption and hardness according to the load axes. The maximum and minimum puncture force values were determined at the Fernor (572 N) with y–y axes and Chandler (211.9 N) with z–z axes, respectively. Also, the highest hardness and the lowest deformation values were obtained for Kaman (y–y axes) and the highest deformation and the lowest hardness were determined at Bilecik (x–x axes). The energy absorption values changed as follows: 0.455–1.086 J, 0.404–0.985 J and 0.426–1.051 J for x–x, y–y and z–z axes, respectively.
