The scientific article presents the results of research work on the study of varietal characteristics of sour cherry and sweet cherry and methods for artificial formation of tree crowns at the level of photosynthetic activity of leaves with the orientation of growing trees by their intensive technology. Zoned cherry varieties Shubinka, Podbelskaya and Shpanka chernaya, sweet cherry Bakhor, Revershon and Drogana jyoltaya grown on a weak vegetatively propagated rootstock BBA-1 and BCL-2 (Krymskiy-5) were used as the object of the study. As a result of the conducted research, it was found that the optimal crown system for varieties of sour cherry and sweet cherry is a five skeletal wall. The formation of the crown in these forms contributes to a decrease in the volume of the crown by an average of 25%, at which the net productivity of leaf photosynthesis in comparison with the usual formation of the crown — freely growing and sparse-tiered shape, reaches 34.73 g/m2 per day. With the formation of bushy crown forms in cherries and sweet cherries, the level of leaf formation improves and the chlorophyll content in the leaves increases to 13.42 mg /g of fresh weight of leaves.

In the scientific article presents the results of research on the study of varietal cherries and artificial ways of formation of the trees to the level of photosynthetic activity of leaves with the orientation of growing trees, their intensive technology. In the research, the varieties of cherries Shubinka, Podbelskaya and Shpanka Chernaya (black) zoned in the Republic, as well as sweet cherries Volovye serdtce, Revershon and Bahor, grown on a low-growing vegetatively propagated rootstock VVA-1 and VSL-2 (Krymsky-5) were used as the object of research. As a result of the conducted research, it was found that the optimal crown system for cherry and sweet cherry varieties is the five-skeletal wall. Crown formation in these forms helps to reduce the volume of the crown to an average of 25%, at which the net productivity of leaf photosynthesis in comparison with the usual crown formation – free-growing and sparse-tiered reaches a value of 34.73 grams/m2 per day. When forming bushy forms of the crown of cherries and sweet cherries, the level of leafiness of leaves improves and the content of chlorophyll in them increases to 13.42 mg/g of raw leaf mass.

AbstractPlums, sweet cherry, and sour cherry trees were spaced 4.5 m × 1.5 m to be trained to “Y” and “V”-trellising systems for mechanical harvesting, with a canopy contact harvester, attending to obtain fruits meeting the requirements of the fresh fruit market. The applied trellising systems were compared with the standard central leader system at the same spacing. The most of trellised trees grew less vigorously than the standard trees, and after 3 years of training, the trees were suitable for mechanical harvesting with the harvester designed at the Research Institute of Horticulture in Skierniewice. The trellised trees were able to set as many fruitlets as those grown in the form of central leader and gave a comparable yield, but differences between cultivars were significant. Light interception in the third year after planting was lower for trees of sour cherry and plum growing in the “Y”-20° and “V” in comparison to the trees with central leader. Illumination of trellised canopies at the level of 0.7 and 1.5 m was the most favorable in “V” system when compared to control and “Y” training systems. Cost of construction for the trellising systems of stone fruits calculated per 1 ha was two times higher when compared with the standard system.

Cherries are known as health friendly fruits due to their abundant phytochemical compositions. This study was conducted to determine phytochemical and pomological fruit properties of different cherry species including mahaleb (Prunus mahaleb L.), wild sweet cherry (Prunus avium L.), wild sour cherry (Prunus cerasus L.), two sweet cherries (‘Napoleon’ and ‘Starks Gold’) and one sour cherry (‘Kütahya’) cultivars. For this aim, together with various pomological traits, total phenolics and anthocyanin contents, antioxidant capacity, organic acids, sugars, were analyzed in fruits of relevant genotypes. Results of all examined traits significantly varied between genotypes. Mahaleb showed the highest TSS (30.17%), fructose (8.71 μg/g) and glucose (20.74 μg/g) contents. Wild sour cherry gave the highest antioxidant capacity (13.25 mmol TE/kg total weight), anthocyanin (351.0 mg Pg-3-glk/kg total weight), citric acid (0.56 μg/g) and malic acid (2.96 μg/g) contents. As a rootstock, mahaleb was found to be superior in some of the traits when compared to wild sweet cherry. Significant correlations were observed between various traits. Additionally, principal component analysis (PCA) revealed different relationships among the traits and evaluated genotypes.

Biodiversity of natural populations, biodiversity located on farm and the introduced cultivars and selections are a rich source of genetic variability in sour and sweet cherries, but they have never been bread with the aim of creating decorative varieties. Low vigour ? dwarfing and upright ? sour cherry genotypes, NS 1/16 KK and NS 1/24 KK, were selected from natural population of Fruska Gora and private arboretum, respectively. Sweet cherry selections NS 6/15 K and RS 8/27 were part of on farm conservation of genetic resources. Furthermore, reduction in vigour was achieved by defining specific combining abilities as a result of rootstock/scion interaction. The outcome of this study is unique columnar and dwarf forms that integrate specific genetic potential of varieties and selections, their interaction with rootstocks and traditional horticultural skills. Collected biodiversity is another confirmation that the Balkan peninsula is one of the most valuable secondary centres of genetic diversity and inexhaustible gene pool for breeding both, varieties and vegetative rootstocks.

This paper is about studying the rootstocks for stone fruit breeds (sweet cherry) in condition of Hissar valley in Tajikistan. Each type of rootstock has its own biological characteristics and imposes specific requirements for growing and development, both during reproduction in the mother plantation and during the growth of trees. For example, the root system in sour cherry is more superficial that of wild sweet cherry. Therefore, the care of trees grafted on sour cherry and wild cherry and of mother plantation bushes of these rootstocks cannot be same. Besides, there are very significant differences among the individual groups of rootstocks. Wild cherry, Mahaleb cherry and Lubskaya cherry are used as rootstocks in the conditions of the Hissar Valley in Tajikistan. High specificity of sweet cherry cultivar varieties depends on the rootstocks. Phenological observation were carried out in our experiments during years 2013-2018 in order to study their winter resistance, yield capacity and fruit quality. The same care for root and grafted plants was carried out during the entire observation period. At the same time a certain ratio between the leaf system of the rootstock and the graft was maintained by trimming the crown. As a result of the evolution and selection, we have identified the wild cherry forms which are distinguished by the highest yields. The most valuable cultivar varieties are Napoleon cherry and Bagration cherry. Compotes made of these varieties have received high evaluation in tasting.

The aim of this study was to evaluate the usefulness of the texture and geometric parameters of endocarp (pit) for distinguishing different cultivars of sweet cherries using image analysis. The textures from images converted to color channels and the geometric parameters of the endocarp (pits) of sweet cherry ‘Kordia’, ‘Lapins’, and ‘Büttner’s Red’ were calculated. For the set combining the selected textures from all color channels, the accuracy reached 100% when comparing ‘Kordia’ vs. ‘Lapins’ and ‘Kordia’ vs. ‘Büttner’s Red’ for all classifiers. The pits of ‘Kordia’ and ‘Lapins’, as well as ‘Kordia’ and ‘Büttner’s Red’ were also 100% correctly discriminated for discriminative models built separately for RGB, Lab and XYZ color spaces, G, L and Y color channels and for models combining selected textural and geometric features. For discrimination ‘Lapins’ and ‘Büttner’s Red’ pits, slightly lower accuracies were determined—up to 93% for models built based on textures selected from all color channels, 91% for the RGB color space, 92% for the Lab and XYZ color spaces, 84% for the G and L color channels, 83% for the Y channel, 94% for geometric features, and 96% for combined textural and geometric features.

In the present study, we utilized high throughput and Sanger sequencing to determine the complete nucleotide sequence of a putative new ilarvirus species infecting sweet cherry, tentatively named prunus virus I (PrVI). The genome of PrVI is comprised of three RNA segments of 3474 nt (RNA1), 2911 nt (RNA2), and 2231 nt (RNA3) and features conserved motifs representative of the genus Ilarvirus. BlastN analysis revealed 68.1–71.9% nt identity of PrVI with strawberry necrotic shock virus (SNSV). In subsequent phylogenetic analysis, PrVI was grouped together with SNSV and blackberry chlorotic ringspot virus (BCRV), both members of subgroup 1 of ilarviruses. In addition, mini-scale surveys in stone fruit orchards revealed the presence of PrVI in a limited number of sweet cherries and in one peach tree. Overall, our data suggest that PrVI is a novel species of the genus Ilarvirus and it consists the fifth member of the genus that is currently known to infect Prunus spp.

Early performance (6–8 yr) of Macspur McIntosh, Golden Delicious, and Spartan apple (Malus domestica Borkh.); Fairhaven peach [Prunus persica (L.) Batsch.]; Montmorency sour cherry (P. cerasus L.); and Lambert sweet cherry (P. avium L.) trees, tissue cultured (TC) on their own roots, was compared with that of the same cultivars budded on commercially used rootstocks. TC trees of all apple cultivars were similar in size to trees budded on Antonovka seedling or M.4 and exceeded the size of trees budded on M.26. They were delayed in flowering and in cropping compared with trees budded on M.26 and M.4. No difference in titratable acidity, soluble solids, flesh firmness, weight, flavor, and color between fruit from TC trees and from trees on M.4 and Antonovka seedlings was detected in 1 yr of measurement. However, fruit from TC Golden Delicious was more russeted and fruit from TC Spartan had more soluble solids. The difference in fruit appearance between TC and budded trees may result from a root-stock effect or a difference in budwood source, because Spartan fruit from trees on M.4 was more russeted than Spartan fruit from TC trees, but was not different from Spartan fruit from trees on Antonovka seedling. Trees of Macspur McIntosh on TC M.26 and on stool-layered M.26 were similar in size and yield efficiency. TC Fairhaven was larger in size than Fairhaven on Siberian C seedling, but was less yield efficient. No difference in fruit size, flesh firmness, or color was detected between fruit harvested from peach trees on the different roots. Montmorency and Lambert TC and on F12/1 were similar in tree size, respectively, but Montmorency and Lambert TC were more yield efficient than on F12/1. Fruit of TC Lambert was lighter in color and had higher titratable acidity than that of Lambert on F12/1, perhaps a result of earlier fruit maturity.

Abstract The work is focused on the evaluation of variability of morphological and pomological characteristics of several old sweet cherries (Prunus avium L.) that were found in different Slovak regions. The experimental work has been performed during two years, 2014 and 2015. The following characteristics according to the descriptor list of subgenus Cerasus were evaluated - period of flowering and ripening, morphological characteristics of the flowers, fruit size, fruit weight, and quality parameters. The results showed high variability of evaluated accessions. From the 13 surveyed localities, the most valuable accessions were found in the locality Hornį Streda - places Čachtice, Krakovany, Nitra, and Brdárka. During the collecting expeditions, 170 accessions of sweet cherry, with fruit of the different quality were found. The most interesting accessions were grafted onto rootstocks with different intensity of growth (Prunus avium L., Prunus mahaleb L., and ‘Gisela5’). Some of the selected cherry accessions can be used for commercial growing after tests, while some of them can be used only for collection of genetic resources and as potential genitors in breeding programmes.
