Various treatments are carried out in order to extend both the shelf life and storage life of fresh fruit and vegetables after harvest and among them non-toxic for humans, environmentally and economically friendly alternative treatments are gained more importance. In the current study, methyl jasmonate (MeJA), cytokinin, and lavender oil which are eco-friendly and safe for human health were applied on apricot fruit. The treated fruit were stored at 0 °C and 90–95% relative humidity for 25 days and catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX) enzyme activities and lipid peroxidation of apricots after treatments were studied. According to the findings obtained from the study, it was observed that 5 ppm cytokinin and 1000 ppm lavender oil treatments of apricot fruit gave better APX and CAT enzyme activity, respectively. In addition, better SOD enzyme activity in fruit was obtained with MeJA + lavender oil treatments. As a result, it can be emphasized that the product quality of apricot fruit is preserved as both the eco-friendly application of MeJA, cytokinin, and lavender oil separately from each other and the treatment of combinations between these compounds activate the enzymatic antioxidant defense systems of apricot fruit after harvest.

The northeastern Anatolia region of Turkey is one of the richest plant biodiversity areas in Turkey. This study describes some important tree and fruit characteristics of 20 seed-propagated summer apple genotypes from northeastern Anatolia using morphological and biochemical markers. The genotypes were evaluated morphologically for tree growth habit, ripening date, fruit weight, fruit firmness, fruit shape, fruit color, fruit taste, juiciness and aroma. The biochemical characteristics measured were organic acids, SSC (soluble solid content), titratable acidity, vitamin C, total phenolic content and antioxidant capacity. We found significant differences for most of the morphological and biochemical characteristics. The genotypes exhibited quite diverse harvest dates ranging from 4 July to 16 August. Summer apple genotypes had fruit weight between 101.9 g and 133.5 g. The genotypes had diverse fruit shapes, including round, conic and oblate, and over fruit colours such as pink, red, yellow and green. Genotypes GUM7 and GUM13 stood out for fruit weight, SSC, total phenolic and antioxidant capacity. GUM7 and GUM13 present dissimilarity from the other genotypes. While the first showed a lower average fruit weight, SSC, total phenolic content and antioxidant capacity, the second revealed higher average of fruit weight, total phenolic content, antioxidant capacity and higher SSC. Due to their favorable characteristics, GUM13 can be used for further crosses with genotypes of other groups, which also present favorable characteristics.

The food needs for increasing population, climatic changes, urbanization and industrialization, along with the destruction of forests, are the main challenges of modern life. Therefore, it is very important to evaluate plant genetic resources in order to cope with these problems. Therefore, in this study, a set of ninety-one walnut (Juglans regia L.) accessions from Central Anatolia region, composed of seventy-four accessions and eight commercial cultivars from Turkey, and nine international reference cultivars, was analyzed using 45 SSR (Simple Sequence Repeats) markers to reveal the genetic diversity. SSR analysis identified 390 alleles for 91 accessions. The number of alleles per locus ranged from 3 to 19 alleles with a mean value of 9 alleles per locus. Genetic dissimilarity coefficients ranged from 0.03 to 0.68. The highest number of alleles was obtained from CUJRA212 locus (Na = 19). The values of polymorphism information content (PIC) ranged from 0.42 (JRHR222528) to 0.86 (CUJRA212) with a mean PIC value of 0.68. Genetic distances were estimated according to the UPGMA (Unweighted Pair Group Method with Arithmetic Average), Principal Coordinates (PCoA), and the Structure-based clustering. The UPGMA and Structure clustering of the accessions depicted five major clusters supporting the PCoA results. The dendrogram revealed the similarities and dissimilarities among the accessions by identifying five major clusters. Based on this study, SSR analyses indicate that Yozgat province has an important genetic diversity pool and rich genetic variance of walnuts.

Apricot fruits are a favorite for consumption; however, their kernels are a rich source of nutritionally interesting substances, too. Nevertheless, in processing of apricots, the kernels remain often unused. In this study, 32 cultivars of different origin were analyzed for their protein content and content of secondary metabolites (phenolics and flavonoids). The weight and taste of kernels were assessed and these data were summarized for an evaluation of the attractiveness of the studied apricot kernels. Results showed that the protein content of kernels ranged from 14.56% to 28.77% and did not depend on the origin or weight of kernel, or taste. In addition, total phenolic (63.5–1277.3 mg GAE/100 g DW) and total flavonoid (0–153.1 mg CE/100 g DW) contents and antioxidant capacity (483.4–2348.4 mg TE/100 g DW) were measured in kernels. In conclusion, the Czech hybrids LE-5959, LE-5500 and French cultivar Koolgat are prospective for kernel processing and consumption because of their high protein content and sweet taste. Hybrid LI-3-6, originating in China, showed high protein content as well but because of bitter taste could be useful rather in medicine.

In this study, agro-morphological, sensory and biochemical characteristics of 23 plum genotypes belonging to Prunus spinosa L. subsp. dasyphylla (Schur) Domin growing wild in the West Black Sea Region in Turkey were investigated. Agro-morphological, sensory and biochemical properties of genotypes were highly different from each other. Principal component analysis was performed to determine the correlation between these properties and genotypes. The variation in the study was determined to be 63.5% in agro-morphological properties, 53.8% in organic acids and 46% in phenolic compounds. In terms of fruit weight, 14BLM08 genotype (38.42 g) was determined to be superior to other genotypes. The fruit firmness value, which is important in the storage of fruits, was recorded as the highest in the 14BLM14 genotype (9.07 kg/cm2). Chlorogenic acid was higher than the other phenolic compounds and the highest value was obtained in the 14BLM20 (11.45 mg/kg) genotype. It was recorded that the value of malic acid, which is the major organic acid of the plums, varied between 269.65–1294.64 mg/100 g. Genotypes showed diverse vitamin C content, and the highest value was found in the 14BLM18 genotype as 54.42 mg/100g. Each genotype showed superiority according to the type of traits, and thus breeders may have used these genotypes as the superior ones for specific plum breeding purposes. In addition, these genotypes could be satisfactorily used in domestication.

Cornelian cherries has been grown Balkan peninsula no apparent disease and pest problems for centuries. The most important pomological and technological properties of cornelian cherry genetic resources (eleven local and introduced varieties and selections) in Gornje Polimlje, Montenegro were studied in four–year periods. Fruit weight, stone weight, and mesocarp/stone ratio shows great variation and varied between 1.89 to 6.16 g, 0.32 to 0.64 g and between 76.66 and 90.59%, respectively. Genotypes significantly differed each other in terms of yield determined as per trunk cross section area (TCSA). For better visualization of the agronomical traits important to the yield, i.e., yield per TCSA and fruit weight data is presented in combination as measured in the years of study. The best promising genotypes are Vladimirskiy, Chisinau yellow, and Krupnoplodni NS, which had consistently higher yield and large fruits for sustainable fruit production. Dry matter, total sugars, reducing sugars, sucrose, total acidity, Ca–pectate, vitamin C, total anthocyanins, total polyphenols, and ash content of cornelian cherry cultivars and selections were found between 19.81–24.46%, 10.94–14.47%, 10.44–13.09%, 0.24–1.23%, 1.92–2.51%, 2.76–4.43%, 41.09–101.27 mg/100 g, 0–157.06 mg/100 g, 183.91–307.9 mg/100 g, and 0.89–1.16%, respectively. The amount of potassium, which predominates in percentage of minerals in the ash, ranged from 2888 to 3574 mg/kg. The extensiveness of the study leads, therefore, to several clear conclusions and recommendations. Consistently, the best balance of biochemical elements in combination with good yield and fruit size measurements is found in selection Krupnoplodi NS. If consider fruit size and yield efficiency are priority, Vladimirskiy, Chisinau yellow, Kosten 3, and Krupnoplodni NS have clear advantage over the other genotypes. The study highlights the importance of local cornelian cherry selections for sustainable cornelian cherry production in Montenegro.

Wild edible fruits have been used centuries by local people mainly for nutrition purposes and they have attracted the attention of researchers in the last decade throughout the world. Among wild edible fruits, the strawberry tree (Arbutus unedo) is widely distributed mainly in Mediterranean countries. However, the lack of information about strawberry tree genetic resources in Mediterranean countries is a major cause of its low exploitation by breeders. For a practical use and exploitation of the strawberry tree native germplasm, phenological, morphological, and biochemical characterization of the plant is essential. In this study, some important phenological, morphological, and biochemical characteristics of sixteen local strawberry tree genotypes were determined. Significant variations (p < 0.05) were observed in most of the investigated phenological, morphological, and biochemical traits of the genotypes. The genotypes were harvested between 2–21 November. The fruit weight and the number of fruits per cluster of the genotypes varied from 3.89 to 6.86 g and 3.61 to 7.94, respectively. Vitamin C and total dietary fiber contents of genotypes were found quite variable, ranging from 58 to 93 mg/100 g and 7.04 to 12.36 g/100 g, respectively. The fruits of the strawberry tree include mainly fructose and glucose rather than sucrose. Local strawberry tree genotypes are found to be promising for further valorization through horticultural characteristics for breeding. Some genotypes had significantly higher fruit weight, vitamin C concentrations, total dietary fiber, and total phenolic concentration and may be good selections for producing health products.

The nutritive quality of food and the aesthetic aspect contribute to the appearance of consumed food. In this study, apricot (Prunus armeniaca L.) flowers were used to determine vitamin C, total phenolic content, flavonoids, antioxidant capacity, carotenoids, anthocyanins, and amygdalin. Vitamin C content fluctuated between 24.97 and 47.35 mg·100 g–1 fresh weight (FW). The results show that all apricot flowers are a good source of phenolic compounds [404.08–768.45 mg gallic acid equivalent (GAE)/100 g FW] and flavonoids [198.76–538.11 mg catechin equivalent (CE)/100 g FW], and have good antioxidant capacity [414.66–1026.18 mg Trolox equivalent (TE)/100 g FW]. A high value of anthocyanins was measured in ‘Vestar’ (28.41 mg·100 g–1 FW) and also in ‘Blenheim’ (13.40 mg·100 g–1 FW). On the contrary, a low value was found in ‘Scout’ (1.60 mg·100 g–1 FW). The highest value of carotenoids was measured in ‘Blenheim’ (6.41 mg·100 g–1 FW), and the lowest in ‘Chuang Zhi Hong’ (1.36 mg·100 g–1 FW). Amygdalin content fluctuated between 110.81 and 419.78 mg·100 g–1 FW. Newly acquired information about the composition and nutritional value of edible flowers give reasons for their consumption.

Little cherry virus 1 is one of the pathogens associated with little cherry disease of cherries. The host range of the virus is widening and recently it has been detected in apricot trees in the Czech Republic, Hungary, and Morocco. To obtain a view about the importance of apricots in the epidemiology of the virus, a survey was conducted in Czech apricot-growing areas. Little cherry virus 1 was detected in seven out of 13 locations, and the infection was noted predominantly in old orchards, but its frequency was low. During the survey, an infected almond tree developing severe leaf mosaic was also detected. Using high-throughput sequencing and Sanger sequencing, five near-complete genome sequences and another 20 partial ORF8 sequences were obtained. Phylogenetic analysis showed a close relationship of most of the apricot isolates to the phylogenetic group G3 with UW2, UW1, and ITMAR isolates. Three apricot isolates, including the almost complete Apr 184R isolate and almond isolate Alm138, showed homology within the phylogenetic group G5. The analysis clearly demonstrates the presence of isolates of this type in Europe. The 4-year-long survey of selected pomological characteristics showed that infection with the virus is generally latent, but the infection could significantly affect the ripening of the fruit of some apricot genotypes. A significant decrease in the fruit yield was noticed for ‘Magyar Kajszi’. The potential routes of the transmission of little cherry virus 1 to apricots are discussed in the context of propagation practice.

The cultivation and breeding of new pear tree varieties have great potential, especially with the changing climate. The introduction of genetic resources and varieties from regions with a high genetic diversity can have a positive effect on the cultivation of pear trees in our region. In this experiment, a total of 23 Asian pear varieties originating from Japan and China were assessed. Based on the values obtained, the varieties were sorted, and suitable varieties for the conditions of the Czech Republic were selected. The early-maturing varieties that proved to be promising were ‘Shinseiki’ and ‘Zao Su Li’ due to their refreshing juiciness, plasticity and ease of cultivation. generally low demand. The ‘Shinseiki’ bears medium- to small-sized fruits (103 g on average). The size of the fruits of the evaluated cultivar ‘Zao Su Li’ can reach very large sizes (255 g on average). The medium-maturity varieties suitable for the conditions of the Czech Republic were ‘Hosui’ and ‘Dangshansu Li’ (ripening on the September 11–19 on average) and another interesting variety, ‘Kirgizkaja zimnaja’. Other suitable medium-maturity varieties are ‘Nijisseiki’, ‘Sha Li’ and ‘Pung Su’. Of the assessed late-maturing varieties, the promising ones were ‘Ya Li’ and ‘Mut Chen’, especially due to their relatively high storability under cold storage.

The service tree (Sorbus domestica) is a wild fruit tree with immense medicinal and industrial value. This study aimed at determining the four major groups of antioxidants (flavonoids, phenolic acids and aldehydes, catechin and procyanidin) in rootstocks of Crataegus laevigata (genotypes O-LE-14 and O-LE-21), Aronia melanocarpa (genotypes O-LE-14 and O-LE-21), Chaenomeles japonica (genotype O-LE-9) and Cydonia oblonga (BA 29) (genotypes O-LE-14 and O-LE-21). Hyperoside (Quercetin 3-D-galactoside) was the most abundant flavonoid compound, since its average content in the rootstocks of Crataegus laevigata (O-LE-21) was 180.68 ± 0.04 μg·g−1. Dihydrokaempherol was the least frequently found flavonoid compound, with an average concentration of 0.43 ± 0.01 μg·g−1 in all the rootstocks of plants considered in this study. Among the phenolic compounds, the most represented one was protocatechuic acid, with 955.92 ± 10.25 μg·g−1 in the rootstocks of Aronia melanocarpa (O-LE-14). On the other hand, the least represented p-Coumaric acid exhibited the average concentration of 0.34 ± 0.01 μg·g−1 in the plant rootstocks. Epicatechin was the most abundant catechin compound, with a content of 3196.37 ± 50.10 μg·g−1 in the rootstocks of Aronia melanocarpa (O-LE-14). The lowest represented catechin compound was epigallocatechin, with the average concentration of 0.95 ± 0.08 μg·g−1 in the screened plant rootstocks. From the procyanidin compounds, the most abundant one was procyanidin b2 in the rootstocks of Crataegus laevigata (O-LE-14), with a concentration of 5550.40 ± 99.56 μg·g−1. On the contrary, procyanidin a2, with an average concentration of 40.35 ± 1.61 μg·g−1, represented the least frequent procyanidin compound in all the plant rootstocks screened herein.
