This research was carried out to see the effects of organic farming and determine the yield and some pomological characteristics of apricots in Isparta, Turkey. Isparta province which is located in the west Mediterranean part of Turkey has also gained importance in terms of especially organic apricot production. Two apricot varieties (Hasanbey, Alyanak) were grown with organic farming practices in this study. These two varieties are table types apricot varieties commonly grown in Turkey’s one of the world's major producers. In this research, pomological characteristics as fruit size (fruit height, fruit width, fruit weight, fruit length), fruit firmness, pH, total soluble solid (TSS) content, titrable acidity (TA) and yield values were determined. Total phenolic and antioxidant activity were also determined. Hasanbey cultivar had higher yield value (66.21 kg/tree) than Alyanak (45.71 kg/tree) cultivar. At the same time the total phenolic content of Hasanbey (307.12 mg GAE/100g) variety was determined higher than Alyanak (175.91 mg GAE/100g). Antioxidant activity of Alyanak and Hasanbey were determined as 32.86 mg/ml IC50 and 17.37 mg/ml IC50 respectively. In terms of observed characteristics, Hasanbey cultivar was found to be prominent in Isparta. It can also been recommended for other places similar to Isparta ecological conditions (highland climate).

Apricot (Prunus armeniaca L.) is one of the most important members of Prunus and its trees bears delicious and nutritious fruits during summer months in the temperate zones in the world. Apricot cultivars are propagated asexually which consists of clones. Information on inter-clonal variations in apricot cultivars can assist us in the selection of better clones from commercial cultivars. We aimed to determine morphological traits (fruit weight, seed weight, kernel weight, flesh/seed ratio, shape index, fruit firmness, color index), nutritional (sugars and organic acids) and nutraceutical (total phenolic, total flavonoids, total carotenoid and antioxidant activity) composition of 18 clones of Sekerpare apricot cultivar grown together in Kagizman district in eastern Turkey. Results showed significant differences among clones concerning most of the morphological traits, nutritional and nutraceutical compositions. Fruit weight, flesh/seed ratio and fruit firmness of clones were in range of 23.14–27.11 g, 11.21–13.14 and 3.88–5.11 kg/cm2, respectively. Fruit shape index was slightly similar among all clones which was between 0.95 and 1.03. Citric acid and sucrose were found to be the predominant organic acid and sugar among clones which varied from 728 to 915 mg/100 g and 7.11 to 9.94 g/100 g, respectively. The clone ‘KS2’ exhibited the highest level of total phenol (67.1 mg gallic acid equivalent per 100 g) and antioxidant activity (2.16 μmol trolox equivalent per g). The study confirmed the diversity among Sekerpare clones and effectiveness of combining morphological, nutritional and nutraceutical analyses in assessment of Şekerpare clones and its use for future pre-breeding programs.

Some physico-chemical properties of ten pomegranate accessions collected from different districts in the Kurdistan region of Iraq were investigated in this paper. Considerable correlations between the characteristics studied were found and valuable pomological traits were observed. Cluster analysis showed the homonyms between some pomegranate accessions. Principle component analysis reported that the component describing the greatest variability also positively correlated with fruit weight, total aril weight, total peel weight, volume of juice, total soluble solids (TSS), fruit length, fruit diameter, pH, aril length, and 100-seed fresh weight, but negatively correlated with titratable acidity (TA). Fruit weight was firmly correlated with total aril weight, total peel weight, volume of juice, TSS, aril length, 100-seed fresh weight, fruit length and fruit diameter. The volume of juice was correlated with TSS, aril length, 100-seed fresh weight, fruit length, fruit diameter and it was observed that with an increase in the fruit size, the volume of juice increased as well. The correlation between total phenolic compounds and antioxidant capacity was not observed. The associations found among physical and chemical traits suggest that consumers should use large fruits with large arils so that they have more juice. Thus, ?Choman?, ?Raniyeh? and ?Halabja? were juicier than other accessions.

Fruit samples of ‘Granada’, ‘Wonderful’ and ‘Hicaznar’ cultivars were collected in productive pomegranate orchard in Neretva valley, Metković (Croatia) and their pomological and chemical properties were compared. Significant differences among cultivars were noted between the studied traits. Fruit weight ranged from 429.37 g to 359.43 g and the lowest was recorded in cv. ‘Hicaznar’. Color of peel, aril and juice of all investigated cultivars was intensively red and dark red, respectively. ‘Granada’ and ‘Wonderful’ stood out with high juice yield compared with ‘Hicaznar’. Total soluble solid (TSS) of ‘Hicaznar’ (18.61%) was higher than that of ‘Wonderful’ (16.64%). Total acidity (TA) significantly differed among cultivars and ranged from 1.6% to 2.1%. According to the TSS/TA ratio investigated cultivars belong to the group of sour-sweet cultivars. Dissimilarity between cultivars was found in the phenolics content (TPC). It ranged from 679.6 to 906.6 mg/100 g D.W. where ‘Hicaznar’ stood out as a cultivar with highest TPC and also highest flavonoid and non-flavonoid content (521.1 mg/100 g D.W. and 385.5 mg/100 g D.W., respectively). In ‘Granada’ antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl was recorded for 64.1%, in ‘Wonderful’ 70.2% and the highest in ‘Hicaznar’ (74.5%). Results of this assessment are the basis for practical determination of the pomegranate use.

Garcinia buchananii Baker (Family,Cluciaceae/Guttiferae) is an underutilized indigenous fruit tree that produces edible fruits that are used as both food and medicine in tropical Africa. This study evaluated the physical and chemical characteristics of G. buchananii fruits collected from Uganda and Rwanda. Ripe fruits were harvested during their peak seasons in Masaka and Bugesera Districts in Uganda and Rwanda, respectively. The fruits were analyzed for physical characteristics including; fruit weight, fruit size (that is length and width), number of seeds per fruit, seed weight, seed dimensions(length, width and breadth); chemical characteristics (pH and titratable acidity), proximate composition (moisture content, protein, fat, dietary fibre, carbohydrates and energy), mineral composition (K, Na, Ca, Mg, Ca, Fe, Zn, Cu), and bioactive components (total phenolic compounds, flavonoids and anthocyanins; and antioxidant activity). Data were statistically analyzed using a student T-test (p≤0.05). The results indicated that fruit weight and pulp content ranged from 6.3±1.3-9.5±2.8g and 54.1±10.6- 81.1±6.5%, respectively. Titratable acidity of the pulp ranged from 6.1±0.8 to 7.1±0.1 %. Nutritionally, dietary fibre, vitamin C, iron and zinc ranged from 20.0±0.4 -22.6±1.8 g/100g, 32.8±3.2-42.0±3.3 mg/100g, 4.8±0.2 - 6.5±0.8 mg/100g and 1.1±0.0 -2.5±0.1 mg/100g, respectively. The total phenolic compounds and antioxidant activity ranged from 996.7±50.5 - 1147.5±47.4 mg/g GAE (Garlic Acid Equivalent) and 8.0±0.2- 8.4±0.1 mg/100g AAE (Ascorbic Acid Equivalent) as IC50, respectively. There was a significant difference (p≤0.05) in the physical characteristics (weight, length, width and breadth), nutritional composition and bioactive components of the fruit samples of the two countries. Assessment of the nutrients indicated that the pulp was rich in vitamin C, iron, zinc, copper and dietary fibre. The pulp also contained phenolic compounds with antioxidant activity. The seeds had 6-24% crude oil content with palmitic, stearic, oleic and linoleic as major fatty acids. The total unsaturated fatty acids in the seed oil ranged from 58.4-59.5%. Although this finding showed significant differences (P≤0.05) in the physical and chemical of G. buchananii fruit from Uganda and Rwanda, the nutritional composition and bioactive component information has shown the potential of the fruits for processing into high-value nutraceuticals.

Soilless growing systems can improve water-use efficiency, especially in closed soilless growing systems. The main purpose of this study was to evaluate the effects of different transplanting conditions, and determine how supplying H2O2 as an oxygen source to the rhizosphere of strawberry plants in a soilless growing system affects plant growth, fruit yield and fruit quality. Strawberry plants (Fragaria x ananassa Duch.) cv. ‘Fortuna’ were cultivated in 12 L pots filled with peat substrate, and maintained under conditions of natural light and temperature. Treated plants were supplied with hydrogen peroxide (H2O2) (H1) and control plants did not receive H2O2 (H0). In terms of the transplanting conditions, the plants were transplanted in October (T1), and either maintained in a culture chamber (T2), or refrigerated (T3), for one month, before being transplanted. A completely randomized block design with two treatment factors (transplanting conditions, and H2O2 treatment) and five replications was established. Then, we determined the fruit per plant, yield per plant (g plant−1), fruit weight (g fruit−1), fruit size (mm), SPAD values, crown number, crown diameter (mm), flower number, firmness (g cm−1), pH, total soluble solid (TSS), titratable acidity (TA) and TSS/TA. During the early crop cycle, there were not significant differences between treatment and the transplanting conditions that significantly affected the fruit weight and fruit size, although T3 produced the highest values. During the late crop cycle, the H2O2 treatment affected fruit per plant, yield per plant (g plant−1), and crown diameter, with H1 producing the highest values. Furthermore, the transplanting conditions affected yield per plant (g plant−1), old SPAD values, crown diameter, firmness, TSS, TA and TSS/TA.

The Impact

Irrigation is a major activity in arid and semi-arid regions for many crops, including orchards. The deficit irrigation is an alternative in the context of global warming. The crop studied was apricot, 'Orizont' cultivar, 16 years old, grafted on the 'Constanta 14' rootstock. The planting distance was 4 m between the rows and 5 m between trees in the row. Fruit size and weight are important qualities and yield traits in apricot (Prunus armeniaca L.), but the factors that influence fruit size and weight remain to be explored. The fruit biometrical characteristics was influenced by the irrigation regime, with the irrigated treatment with 100% AHI (T1) showing significantly (P <5%) higher differences versus T2 and T3. As with fruit biometrical characteristics, the fruit weight determined on the fruits of the studied treatments had the same trend. In this study, we investigated the impact of stress hydric on fruit size and weight at 'Orizont' apricot cultivar in 2019-2020 period.

Sib Families

Variance components and narrow-sense heritabilities were estimated for antioxidant activity (AA), total phenolic content (TPH), and fruit weight in red raspberry (Rubus idaeus L.) fruit from offspring of a factorial mating design. Forty-two full-sib families utilizing seven female and six male parents were evaluated in each of two years in Motueka, New Zealand. In a single year, values within individual half-sib families ranged as widely as 25.3-79.4 μg·g-1 fruit for AA, 205-597 mg/100 g fruit for TPH, and 1.06-7.69 g for fruit weight. Analyses of variance for these three variates demonstrated significant parental source variation in both individual and combined year analyses. For AA and TPH, female parental effects accounted for ≈7% to 19% of total variation, while male effects accounted for ≈6% to 8%. A partially pigment deficient R. parvifolius L. derivative female parent accounted for some of these differences. Female × male parent interaction was not significant for AA and TPH and was marginally significant for fruit weight in combined year analysis. Year had a significant effect on the overall mean AA and TPH, but contributed less than genetic effects to the overall variation in all three traits. Interactions of year with genetic effects were not statistically significant for AA or TPH, indicating that between-year rank or scale changes among families were negligible. The largest proportion of variation was found within rather than among full-sib families. However, variation among plots within full-sib families accounted for 12% to 19% of total variation, indicating environmental differences accounted for some of the observed within-family variation in AA and TPH. Antioxidant activity and TPH were highly phenotypically correlated (r = 0.93); their genetic correlation (r = 0.59) implies that substantial additive genetic factors underlie the phenotypic correlation, but that nonadditive genetic or environmental influences are also important. Both AA and TPH were weakly negatively phenotypically correlated with fruit weight (r = -0.34 and -0.33, respectively), but the corresponding genetic correlations were close to zero. Thus, selection for both high AA or TPH and high fruit weight is possible. Narrow-sense heritability estimates based on variance components from combined year data were h2 = 0.54, 0.48, and 0.77 for AA, TPH, and fruit weight, respectively. These estimates imply a rapid response to selection is possible.
