  • Apfel oder Acai: Brasiliens Obstbau im ökonomischen und klimatischen
           Wandel
    • Authors: M. Blanke
      Pages: 245 - 252
      Abstract: Zusammenfassung Trotz schwieriger wirtschaftlicher Lage (7–10 % Inflation, Konjunkturschwäche, Rezession mit Konsumeinbruch, Petrobras-Skandal und Währungsverlust [4 Real = 1 €]) exportiert Brasilien, weltweit drittgrößter Obstproduzent mit 46 Mio. t Obst auf 2,2 Mio. ha (2013), ca. 3 % der eigenen Obsterzeugung mit einem Warenwert von fast 765 Mio. US $ (2013) – Exportziel für 2017 ist 1 Mrd. US $, davon 80 % nach Europa. Der Apfelanbau Brasiliens zwischen 26° und 31° südl. Breitengrad mit 55 % ‘Gala‘ und 40 % ‘Fuji‘ stieg von 0,65 Mio. t im Jahre 2002 auf eine Rekordernte von 1,4 Mio. t auf 39.600 ha in 2011/12, gefolgt von 1,16 Mio. t in den beiden Jahren 2013/14 und 2014/15 und nur noch 0,8 Mio. t in 2015/16 (Regen zur Blüte) bei leichtem Rückgang der Anbaufläche auf 36.090 ha (2015) aufgrund geringen Kältereizes um Fraiburgo (unter 600 CH) – und damit ähnlicher Erntemenge wie in Deutschland auf 31.400 ha Apfelfläche. Der Apfelanbau in Brasilien ist weitgehend frei von Apfelwickler und Feuerbrand, aber bei 1700 mm Jahresniederschlag von Apfelschorf- und Glomorella-Pilzen betroffen und leidet unter den Folgen des Klimawandels: Ungenügender Kältereiz fördert vertikale vegetative Triebe, flache gesprenkelte Früchte mit langem Fruchtstiel (‘Gala‘), Sonnenbrand (‘Fuji‘) und verhindert den Anbau von Apfel- und Birnensorten mit hohem Kältebedürfnis; warme Nachttemperaturen im Herbst führen zu ungenügender Farbausbildung bei beiden Sorten. Den Obstkonsum Brasiliens von 31,4 kg dominieren die drei Obstarten Apfelsine (7,5 kg), Banane (6,8 kg) und Apfel mit 4,2 kg/Kopf/Jahr (2013) bzw. 6,1 kg/Kopf (2015) im Vergleich zu den großen drei Fleischarten mit ca. 36 kg Rind, ca. 34 kg Schwein und ca. 10 kg Geflügel bei einem Fleischkonsum von ca. 80 kg/Kopf/Jahr. Bisherige staatliche Apfel-Neuzüchtungen von EMBRAPA wie ’Eva’ (low chill, sehr früh; Januar), die nicht lagerfähigen Frühsorten ’Condessa’, ’Monalisa’ und ’Princesa’ (medium chill: 300–450 CH) wurden in den letzten 3 Jahren ergänzt durch neue interessante Lagersorten wie ‘Daiane‘, ‘Venice‘ sowie ‘M 58/07‘ und ‘M 10/09‘ – beide noch ohne Sortennamen – und je eine rote Mutante von ‘Gala‘ (‘Gala, Maxi‘; von RASIP) und ‘Fuji‘ (‘Fuji, Suprema‘) mit 500–600 CH; alle bieten marktorientierte Fruchtqualität mit roten, mittelgroßen, süßen Früchten mit wenig Säure und einem Zucker:Säure-Verhältnis von 25–55:1, fehlt jedoch noch der Marktzugang aufgrund unzureichender Akzeptanz und Vermarktungsstrategie.

  • Study on Antioxidant Components in Rosé Wine Originating from the Wine
           Growing Region of Moravia, Czech Republic
    • Authors: Mojmir Baron; Jiri Sochor; Lenka Tomaskova; Bozena Prusova; Michal Kumsta
      Pages: 253 - 262
      Abstract: The estimation of antioxidants in fruit, vegetables, beverages, and foodstuffs has been discussed in a great number of scientific studies, but until now, problems concerning the analysis of antioxidant components of rosé wine has not been adequately investigated. This paper presented results of a study on antioxidant components contained in some samples of rosé wine originating from the Moravian wine growing region. The experiments involved altogether 48 samples of rosé wine made of grapes of the varieties ‘Blaufränkisch’, ‘Blauer Portugieser’, ‘Pinot Noir’, ‘Sankt Laurent’, and ‘Zweigeltrebe’. Grapes were harvested in 2013. Spectrophotometry was used to estimated antioxidant activity (53–73 mg L−1 GAE), content of total polyphenols (152–369 mg L−1), hydrocinnamic acid (52–148 mg L−1), flavonols (25–294 mg L−1) and anthocyanins (88–1754 mg L−1). The HPLC method was used for the detection of some important antioxidants, i. e. catechin, epicatechin, malvidin-3-glucoside, cis- and trans-resveratrol, ferrulic acid, coumaric acid and caftaric acid. This study enabled to determine basic profiles of the most important antioxidant components of the most popular Moravian red grapevine varieties. The studied wines were analyzed from several different aspects, which is not standard.

  • Electrochemical Properties and Biochemical Composition of Cv. Shiraz Wine
           Grape ( V. vinifera  L.) Depending on Various Dose and Application Time
           of Foliar Microbial Fertilizer Treatments
    • Authors: Demir Kok; Erdınc Bal
      Pages: 263 - 268
      Abstract: Utilization from bio fertilization is well known a considerable tool to improve the yield and fruit quality of various crop fruits through the increasing emphasis on maintain of soil health, minimize environmental pollution and decrease the use of chemical fertilization. In this study, in order to improve wine grape quality features of cv. Shiraz, four different doses of foliar microbial fertilizer, including 0, 1000, 2000 and 3000 ppm were applied at two different terms as Term I (mostly; pre-bloom applications) and Term II (mostly; post-bloom applications). However, there were no influences of application terms of foliar microbial fertilizer treatments; treatment doses had considerable effects on yield and quality parameters. The lowest p-values, meaning the highest berry quality, from doses of foliar microbial fertilizer were obtained from 2000 ppm (105.08 μW), 1000 ppm (110.40 μW), 3000 ppm (112.97 μW) and 0 ppm (119.58 μW). Comparing the applications of foliar microbial fertilizer, it was observed that doses of 2000 ppm (3155.56 mg/kg), 1000 ppm (3000.92 mg/kg) and 3000 ppm (2530.19 mg/kg) exhibited higher total phenolic compounds content when compared with 0 ppm treatment (2206.97 mg/kg). Berries from grapevines applied with the doses of 2000, 1000 and 3000 ppm foliar microbial fertilizer respectively shown higher total anthocyanin content such as 1230.19, 1160.85 and 865.86 mg/kg compared to 0 ppm (637.37 mg/kg). As a result, research the findings indicated that 2000 and 1000 ppm doses of foliar microbial fertilizer were obviously effective on wine grape quality features of cv. Shiraz in terms of electrochemical property, total phenolic compounds content and total anthocyanin content.

  • Chemical and Non-Chemical Thinning Treatments Influence Berry Growth and
           Composition of Cv. Shiraz Wine Grape ( V. vinifera  L.)
    • Authors: Demir Kok; Erdınc Bal
      Pages: 269 - 273
      Abstract: Yield management is important subject in modern grape growing and winter pruning and cluster thinning treatments were used for yield control. Standard cluster thinning is generally labor intensive and expensive method and grape growers try to new methods, which are alternative to cluster thinning for reducing berry set. The goal of the present research was to investigate the effects of chemical thinning treatments such as ethephon (ETH), gibberellic acid (GA3), naphthalene acetic acid (NAA) and non-chemical thinning treatments such as early leaf removal (ELR) and standard cluster thinning (SCT) on decreasing grape yield and enhancing berry composition of cv. Shiraz. In this study, percentages of berry set of cv. Shiraz were decreased by both chemical and non-chemical thinning treatments compared to Control. The results from these two different thinning methods shown certainly significant differences in berry composition of cv. Shiraz. Eventually, the best results in improved quality characteristics of cv. Shiraz were obtained from ELR treatment and treatments of ELR, ETH, GA3, NAA and SCT successively resulted in considerable enhancements in quality attributes of cv. Shiraz.

  • Antioxidant Capacity, Phenolic Compounds and Antioxidant Enzymes of Wild
           Grape Seeds from Different Accessions Grown in Iran
    • Authors: Hamid Hassanpour; Rogayeh Khoshamad
      Pages: 281 - 290
      Abstract: Grape seeds contain high levels of phytochemicals, that have been associated with a reduced risk of chronic diseases. In this study, the polyphenolic content, antioxidant capacity and antioxidant enzymes activity in the seeds of 20 wild grape accessions native to Iran were investigated. The antioxidant capacity of the wild grape seeds was evaluated by DPPH radical scavenging activity, ferric reducing antioxidant power (FRAP) and Fe2+ chelating. Total phenolic (TP), total flavanoid (TF) and total proanthocyanidin (TPA) content ranged from 44.86 to 155.1, 23.21 to 131.91, and 10.11 to 26.10 mg/g seed, respectively. All seed extracts showed remarkable DPPH radical scavenging activity, ferric reducing antioxidant power (FRAP) and Fe2+ chelating ranging from 27.34 to 78.57%, 198.83 to 590.86 µmol TE/g and 23.12 to 62.98%, respectively. Grape seed extracts had the greatest antioxidant enzymes activity guaiacol peroxidase (G-POD), superoxide dismutase (SOD), and catalase (CAT). Based on HPLC analyses, catechin was the most abundant compound identified (25.89 mg/g) for all accessions. Additionally, significant correlations among different antioxidant assays were found. With the high amount of total phenolic content, antioxidant capacity and antioxidant enzymes activity, seeds of P6, P7 and P8 accessions might be evaluated as a nutritional supplement.

  • Estimation of the Colour Properties of Apples Varieties Using Neural
           Network
    • Authors: Zeynel Abidin Kus; Bunyamin Demir; Ikbal Eski; Feyza Gurbuz; Sezai Ercisli
      Pages: 291 - 299
      Abstract: The consumer acceptance and the quality standard of agricultural products such as apple are determined mostly by their colour. Colour is measured with a colorimeter and quantified using the C.I.E. L*, a*, b* colour space system. It is used commonly by researchers for the classification and identification of apple fruit. To the best of our knowledge, the present study is the first study investigating the prediction of some colour properties of six apple varieties through artificial neural networks (ANN). The apple varieties are ‘Amasya’, ‘Starking’, ‘Granny Smith’, ‘Pink Lady’, ‘Golden Delicious’, ‘Arapkızı’ and the colour properties are L* (lightness), a* (redness), b* (yellowness), C* (chroma), h* (hue angle), CI (chroma index). General Regression Neural Networks (GRNN) and Adaptive Neuro Fuzzy Interface System (ANFIS) structures were employed to predict the colour properties. According to the experimental and simulation results, the proposed ANFIS predictor had a superior performance in prediction of these colour parameters.

Among ‘Dare Gazi’ genotypes of Mashhad Esteghlal orchard 23 genotypes were selected base on difference in tree vigor, leaf color, shape and color of fruit and also 33 other commercial and native pear cultivars from Esteghlal orchard and other Mashhad commercial orchards were studied. A total number of 230 DNA fragments were obtained using 11 primers of which 225 were polymorphic. On average, each primer produced 20.9 bands. Dice similarity coefficient ranged from 0.27 (between ‘Dom Kaj’ and Asian pear) to 1 (between ‘Dare Gazi’ 1 and 2 genotypes). Sample cluster dendrogram indicated that 56 genotypes were divided into 12 distinct clusters. The dendogram generated on the principle of Unweight Pair Wise Method using Arithmetic Average (UPGMA) was constructed by Dice coefficient and the genotypes were grouped into 12 clusters. ‘Dare Gazi’ genotypes did not show 100% similarity due to seed propagation or mutation, as ‘Dare Gazi’ 3 and 18 genotypes had the lowest similarity coefficient (0.64). Asian pears were placed in a separate group from European pears. And ‘Dare Gazi’ genotypes from different orchards were grouped separately, but all of them are called as ‘Dare Gazi’ pear for convenience. ISSR molecular marker can well identify the genetic variability among genotypes and cultivars and found suitable for grouping them.

  • Effect of Plant Growth Promoting Rhizobacteria (PGPR) on Branching
           and Growing of Apple Sapling
    • Authors: Nazmi Coşkun; Lütfi Pırlak
      Pages: 309 - 313
      Abstract: According to the control, applications increased sapling height and this increasing was found important as statistically. Generally, bacteria applications more increase than Perlan on sapling height. Effect of bacteria and Perlan applications on sapling diameter showed different in cultivars and years. Generally, sapling diameter was increase by applications. Applications that on branching was important in 2009, but not important in 2010 as statistically. The most effective applications on branching were T8 and BA-8+T8 in ‘Granny Smith’, in ‘Red Delicious, Red Chief’ BA-8+T8 and BA-8, in ‘Fuji’ Perlan and BA-8 in 2009. Effect of applications on lateral branch degree was different in years and cultivars. According to the control, bacteria and Perlan applications raised length of lateral branch also bacteria was more effective than Perlan. Finally, plant growth promoting bacteria more increased branching and sapling quality than Perlan.

      Abstract: Sweet oranges are produced on large scale all over the world and demanded due to less number of seeds and are better juice quality. A study was carried out with the objective to characterize promising sweet orange cultivars for better quality fruits production under different agro-climatic conditions of Punjab (Pakistan). Fruits of three promising sweet orange (Citrus sinensis L. Osbeck) cultivars viz. ‘Blood Red’, ‘Musambi’ and were harvested from commercial citrus groves at five different locations. Starting from Multan, in the direction of increasing altitude, four more sites viz. Sahiwal, Faisalabad, Sargodha and Chakwal were selected after every 100–150 km distance. Fruits were evaluated in terms of different physical and biochemical characters. Results showed significant influence of climatic conditions on physico-chemical properties of the cultivars at all the locations. Fruits harvested from Multan and Sahiwal showed higher fruit weight, diameter and peel weight. More juicy fruits with higher vitamin C content were produced under mild temperature environmental conditions of Chakwal. Overall, ‘Musambi’ fruits had more total soluble solids and reducing and total sugars. ‘Musambi’ was found to be good source of bioactive compounds i. e. vitamin C and total phenolic content, had the maximum antioxidant activity as compared to ‘Blood Red’ and ‘Succari’ and may be explored as potential cultivar in Sargodha and Chakwal.

  • Sustainable Mitigation of Alkaline Stress in Grapevine Rootstocks ( Vitis
           spp.) by Plant Growth-Promoting Rhizobacteria
    • Authors: Ummuhan Karaca; Ali Sabir
      Abstract: Practical use of plant growth-promoting rhizobacteria (PGPR) on plants under stress conditions remains elusive because most of the studies focused on merely evaluating the plant growth-promoting effects on non-stressed plants. This study focused on the effect of root inoculation of different PGPRs on the growth and physiology of grapevine rootstocks 41 B, 99 R and 140 Ru grown in soilless culture with elevated pH. The rootstocks in pots under glasshouse condition were inoculated with Agrobacterium rubi A18 and Bacillus subtilis OSU 142 bacteria in early spring. To increase the pH of growth medium, the plants were watered with 250 mL plant−1 bicarbonate solution (840 g L−1 NaHCO3) four times (beginning at 3–4 cm shoot growth) with one-month interval during the vegetation. Along with the bicarbonate supplementation to growth medium, root rhizosphere pH increased from an initial value 7.76 to the final values between 8.10 and 8.26. Although the bacteria population decreased progressively, they were able to alleviate the negative effects of high pH by improving vegetative growth, leaf physiology and nutrient acquisition in many cases. The bacteria strains employed in this study can be recommended to support grapevine growth and physiology under alkaline conditions for a sustainable and environment-friendly viticulture.

  • The role of Pre-harvest Aminoethoxyvinylglycine (AVG) Treatments on Total
           Phenolics, Antioxidant Capacity and Fruit Quality Attributes of Sweet
           Cherry Cultivars
    • Authors: Kenan Yildiz; Kemal Kilic; Yakup Ozkan; Burhan Ozturk; Emine Kucuker
      Abstract: The present study was conducted to investigate the effects of pre-harvest aminoethoxyvinylglycine (AVG) treatments on fruit quality parameters and bioactive compounds of sweet cherry fruits (Prunus avium L. cvs. ’0900 Ziraat’, ‘Regina’ and ’Sweetheart’). Whole trees were sprayed once with an aqueous solution containing AVG (0, 100 and 200 mg L−1) three weeks before the anticipated commercial harvest. Measurements were performed a week before anticipated harvest date, at anticipated harvest date and a week after anticipated harvest date. AVG treatments significantly maintained flesh firmness of all three sweet cherry cultivars. Harvest was delayed at least for a week through the keeping of flesh firmness with AVG treatments. The treatments slowed down the red skin color development in all three cultivars. The measurements performed over fruits collected at different ripening stages revealed that AVG resulted in decreased total phenolics and total anthocyanin and ultimately decreased antioxidant capacity in sweet cherry fruits. AVG treatments also decreased soluble solids content and increased titratable acidity of the fruits. This study revealed that pre-harvest AVG treatments were more effective in delaying sweet cherry fruit softening. The main advantage is to maintain the firmness of late-harvested fruit by retaining fruit quality attributes of sweet cherry fruit.

           Grown Naturally in Adiyaman Province
    • Authors: Deniz Eroğul; H. İbrahim Oğuz
      Abstract: Turkey is an important gene centre of rosehip populations and rosehip is naturally grown in the province of Adıyaman. This study has been conducted on rosehip fruits found in various altitudes in Adıyaman to determine the changes of their physico-chemical characteristics. The fruit weights of the genotypes used in the study ranged between 2.72 g–1.29 g, fruit width between 14.12–10.44 g and fruit length has ranged between 23.18 mm–18.62 mm. The rosehip genotypes to be processed to food are required to have a bulky fruit and a high amount of fruit flesh. The genotype with the highest fruit flesh ratio was found to have the lowest seed weight by 0.25 g, while the genotypes with the highest seed weight had this value ranging between 0.50–0.59 g. Rosehip genotypes dry matter ratio has ranged between 44.27 and 37.11%. While the a*, b*, C* and h° values of rosehip fruits had significant differences based on the genotypes, L* values had similarities. Genotypes had ranging WSDM contents of 33.56–22.50%, TA contents of 2.96–1.57%, pH values of 4.06–3.82, C vitamins of 782.34–352.16 mg/100 g, total phenol contents of 5.42–3.62 mg GAE/g DM and antioxidant activities of 113.60–56.80 µmol TE/g DM. The rosehip fruits containing high levels of fructose and glucose were found to be low in saccharose content. Fructose, glucose and saccharose contents of rosehip genotype fruits were found to be 22.93–16.86, 20.22–13.77 and 0–0.90 g/100 g DM, respectively. According to the outcomes of the study, physico-chemical characteristics of the rosehip fruits displayed significant differences, and these differences were affected by type, genotype and ecologic conditions.

    • Authors: İkbal Eski; Bünyamin Demir; Feyza Gürbüz; Zeynel Abidin Kuş; Kadir Uğurtan Yilmaz; Mehmet Uzun; Sezai Ercişli
      Abstract: In this study, an adaptive neuro fuzzy interface system (ANFIS) based predictor was designed to predict the physical properties of four almond types. Measurements of the dimensions, length, width and thickness were carried out for one hundred randomly selected samples of each type. With using these three major perpendicular dimensions, some physical parameters such as projected area, arithmetic mean diameter, geometric mean diameter, sphericity, surface area, volume, shape index and aspect ratio were estimated. In in a various Artificial Neural Network (ANN) structures, ANFIS structure which has given the best results was selected. The parameters analytically estimated and those predicted were given in the form of figures. The root mean-squared error (RMSE) was found to be 0.0001 which is quite low. ANFIS approach has given a superior outcome in the prediction of the Physical Properties of Almond Nuts.

  • Polypeptide Alteration During The Cold Stratification In Mazzard Seed
    • Authors: Servet Aras; Emine Arslan; Ahmet Eşitken; Merve Kılıç
      Abstract: Many seeds of woody plants require low temperature for germination and that’s called seed dormancy has been investigated for relations of proteins by several researchers. We determined polypeptide profiles of cold-stratified Mazzard seeds. Seeds were studied in five different periods: seeds in dormancy (none stratified), 30, 60, 90 and 120 days cold-stratified. Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate (SDS-PAGE) of the soluble protein fractions from stratified and none stratified seeds was utilized for determination of changes in polypeptides. SDS-PAGE revealed a decrease in the concentrations of 14 polypeptides and appearance of four low-molecular weight (15.1, 16.3, 17.8 and 19.4 kDa) polypeptides were determined in 90 and 120 day stratified seeds. The study results exhibited the evidences of the involvement of protein changes in response of Mazzard seeds during cold stratification.

           Gumushane, Turkey
    • Authors: Ozgun Kalkisim; Zuhal Okcu; Besim Karabulut; Duygu Ozdes; Celal Duran
      Abstract: The aim of the present research was to investigate the fruit quality of twenty different local pear varieties (Pyrus communis L.), namely Ahlat, Ankara, Arpa, Bıldırcın, Çermai, Cinci, Gelin Boğan, Hacı Hamza, Hahır, Kabak, Kızıl, Kokulu, Mehrani, Menendi, Sulu, Şalgam, Tokat Sultanı, Turşu, Yaz, and Yaz Meyriği, grown in Gumushane province in terms of pomological and morphological characteristics and chemical compositions. The fruit mass, fruit width and length, fruit stem thickness and length, fruit kernel width and length, hardness of pulp, number of seeds, leaf width and length, leaf stem length and thickness, and water soluble dry matter (WSDM) of the pear fruits have been determined as pomological and morphological characteristics. On the other hand, the chemical compositions of the pear varieties have been evaluated in terms of protein, ash, sucrose, fructose, glucose, total sugar, titratable acidity, moisture, and mineral element levels. Both pomological and morphological results demonstrated that the local pear varieties are important in terms of rehabilitation studies and detailed selection studies on these local varieties should be performed. The chemical analyses result of the pear varieties revealed that there is no component that may be harmful to human health when consumed, and also these varieties contains the necessary amount of mineral elements.

  • Root System Distribution of Highbush Blueberry Crops of Various Ages in
           Medium-Textured Soils
    • Authors: Cristian Paltineanu; Mihai Coman; Silvia Nicolae; Irina Ancu; Mirela Calinescu; Monica Sturzeanu; Emil Chitu; Mihaela Ciucu; Claudia Nicola
      Abstract: The paper deals with the spatial distribution of root density in highbush blueberry plantations of various ages for a proper planting distance recommendation and a better irrigation and fertilization management. The environmental conditions consist of sandy-loamy soils and a continental temperate climate. Two highbush blueberry cultivars were studied, ‘Bluecrop’ and ‘Blueray’. Root density (RD) and density of root cross-sectional area (RCSA) were investigated for various root diameters. It was found that the prevalent type of roots in highbush blueberry crops is the hair type, with root diameters less than 0.1 mm. Both RD and RCSA decreased with distance from plant and with soil depth; the 38-year-old crop showed a more developed root system versus the 8‑year-old crop. In both cases the roots did not grow more than 0.6 m laterally and more than 0.7 m deep. According to these results, the planting distances in highbush blueberry could be reduced to substantially increase the number of plants/ha and fruit yield. Irrigation application should be carried out to wet a proper soil volume, about 0.6–0.7 m deep for older crops, and about 0.5 m deep for younger crops.
