  • Spezifisches Gewicht neuer Apfelsorten
    • Authors: Irene Höller; Walter Guerra; Karin Gummerer
      Pages: 85 - 91
      Abstract: Zusammenfassung Am Land- und Forstwirtschaftlichen Versuchszentrum Laimburg wurde in den Jahren von 2007 bis 2013 das spezifische Gewicht von 121 Apfelsorten aus der eigenen Sortensammlung mittels hydrostatischer Methode (Archimedisches Prinzip) ermittelt. Dazu wurde jährlich im selben Zeitraum eine Stichprobenanzahl von 10 Äpfeln pro Sorte mit einer einheitlichen sortentypischen Fruchtgröße untersucht. Die Sorten stammten vorwiegend von den Standorten Laimburg (220 m Meereshöhe) und Latsch (700 m Meereshöhe). Mit den Messdaten wurde eine Klasseneinteilung nach 4 spezifischen Gewichtskategorien von 0,75 bis 0,91 g/cm3 vorgenommen. 76 % der Sorten gliederten sich in die mittleren Kategorien ein, da sie spezifische Gewichtsgrößen von 0,80 bis 0,86 g/cm3 aufwiesen. Bei den spezifisch „sehr leichten“ Sorten war zum Beispiel ‘Golden Delicious’ enthalten und bei den spezifisch „sehr schweren“ Sorten ‘Braeburn’, ‘Nicoter Kanzi®’ und ‘Scifresh Jazz®’. Das spezifische Gewicht verändert sich kaum durch Jahres- oder Standorteinflüsse, da es vielmehr von vorwiegend genetisch bedingten Merkmalen wie beispielsweise dem Interzellularvolumen und dem Trockensubstanzgehalt der Frucht abhängig ist. Auch Fruchtgröße und Reifegrad zählen zu den Einflussfaktoren. Das spezifische Gewicht ist eine interessante Zusatzinformation zur Beschreibung einer Apfelsorte.

  • Effects of Sewage Sludge Amendment on Some Soil Properties, Growth, Yield
           and Nutrient Content of Raspberry ( Rubus idaeus  L.)
    • Authors: Ilker Angin; Rafet Aslantas; Adem Gunes; Murat Kose; Gursel Ozkan
      Pages: 93 - 99
      Abstract: This study was focused not only at the assessment of effects of different sewage sludge application rates on vegetative parameters and yield of raspberry (Rubus ideaus L.) but also heavy metal accumulation in the soil and raspberry leaves. A three-year field study was set up in a completely randomized block design with five sewage sludge application rates (0.0, 2.5, 5.0, 7.5 and 10.0 kg of dry matter per plant) and three replications. One-year-old, virus free ‘Heritage’ saplings were used for the experiment. The results of this study clearly indicated that the sewage sludge application is an effective mean for improvement of vegetative growth, yield, soil and plant chemical properties of raspberry in light textured soils. In addition to macro-element contents, sewage sludge application also caused significant changes in micro-element content of soils. No adverse effects of these increases were observed on plants throughout the experimental period. The most effective application rate was found as 7.5 kg per plant for this ecological condition. It can be concluded that when properly treated and applied to farmland sewage sludge is not only disposed economically but also improved vegetative growth and yield of raspberry.

      Pages: 101 - 107
      Abstract: In this study the mulberry population in the Mediterranean and Eastern Anatolia Turkey was examined with regard to fruit properties. The research material consisted of uncultivated mulberry (Morus spp.) trees. Thirty five mulberry genotypes for table, 6 genotypes for fruit juice, 11 genotypes for syrup (pekmez) and 9 genotypes for drying, were selected, 32 of which belonged to Morus alba, 12 to Morus rubra and 8 genotypes to Morus nigra. Continued and more detailed selection studies with this population of genotypes are necessary to provide material that is suitable for future breeding efforts. It may also be possible to select some of this native material that has sufficient commercial value to justify its release to growers.

  • Forecasting Apple Fruit Color Intensity with Machine Learning Methods
    • Authors: Blaž Germšek; Črtomir Rozman; Tatjana Unuk
      Pages: 109 - 118
      Abstract: In this study, we focused on the possibility of forecasting the development of skin color in apples on the basis of weather forecast by using a machine learning methods. We used supervised learning and generated models via the use of six decision trees. The purpose of the research was to build models that would allow for in-practice-acceptable accuracy in the prediction of the development of fruit skin color (especial a colour parameter a*), for three apple varieties. For cv. ‘Gala, Brookfield’, the most accurate models were generated by using decision tree J48 (89.13% accuracy). For late ripening cv. ‘Fuji, Kiku 8’ and cv. ‘Braeburn, Maririred’, the most accurate model was obtained by using decision tree LMT (91.73 and 96.65% accuracy). The data confirm that the applicability of predictive models strongly depends on the accuracy of weather forecasts. In regard to the seven-day weather forecast, which was used for expert models, the accuracy of the models was, on average, reduced by 10.73%.

  • Effect of Different Treatments on Branching of Some Apple Trees in Nursery
    • Authors: Muzaffer İpek; Şeyma Arikan; Lütfi Pirlak; Ahmet Eşitken
      Pages: 119 - 122
      Abstract: This study was conducted to determine effect of different treatments on branching of one-year-old ‘Fuji’, ‘Granny Smith’ and ‘Red Delicious, Red Chief’ trees which grafted on M9 rootstock. Plant growth promoting rhizobacteria (Pseudomonas BA-8) strain, 6‑Benzyl Adenin (BA) and pinching were used to promote branching. The BA (300 ppm) and BA-8 (109CFU/ml) were applied to first twenty centimeters of the top part of trees. The BA, BA-8 and Pinching was applied to trees at 75 cm in length. According to our results, BA-8 and pinching increased number of branches compared to control and BA treatments for all cultivars. BA-8 increased number of branches in ‘Fuji’, ‘Red Delicious, Red Chief’ and ‘Granny Smith’ from 2.71, 1.70 to 4.25 branches/tree, respectively while pinching increased 1,95 branches/tree in ‘Red Delicious, Red Chief’ and 4,01 branches/tree. The highest branch’s angle was obtained from BA-8 bacteria in ‘Fuji’ (64.46°), and ‘Red Delicious, Red Chief’ (52.08°) and ‘Granny Smith’ (56.91°). BA-8 bacteria treatment was found alternative practice instead of pinching in terms of branching performance.

  • Antioxidant Compounds, Nutritional Quality and Colour of Two Strawberry
           Genotypes from Fragaria  × Ananassa
    • Authors: Violeta Nour; Ion Trandafir; Sina Cosmulescu
      Pages: 123 - 131
      Abstract: In this study, average weight, colour, soluble solids content and titratable acidity were determined as quality parameters of strawberry fruits while ascorbic acid, total anthocyanins, total phenolics, total flavonoids, minerals and trace elements content as nutritional parameters. All these attributes along with the DPPH radical scavenging activity were screened in two strawberry genotypes grown on the same site at the ripe stage. Also, the phenolic profiles of the strawberry fruits were obtained by HPLC. Except colour, results showed no significant differences between cultivars in quality parameters. Ascorbic acid found for ‘Premial’ cv. (81.62 mg/100 g) was twice the amount found in ‘Magic’ cv. (42.15 mg/100 g), total phenolics varied from 207.95 (cv. ‘Premial’) to 249.98 (cv. ‘Magic’) mg GAE/100 g while total flavonoid content in fruits of ‘Magic’ cultivar (79.56 mg/100 g) was 2‑fold higher than the one of the ‘Premial’ cv. The quercetin content ranged from 2.72 to 4.66 mg/100 g, whereas free ellagic acid ranged from 6.79 to 9.03 mg/100 g. The pale shiny fruits of ‘Premial’ cv. (higher L*, ho and chroma index) had a lower total anthocyanin content (19.07 mg CG/100 g) than the bluish fruits of the ‘Magic’ cv. (23.96 mg CG/100 g). An inverse relationship between the levels of ascorbic acid and anthocyanin contents was also noticed in strawberry samples. Significant differences were found also in minerals and trace elements content of the two strawberry cultivars. The results revealed the importance of genetic background for the content of antioxidant compounds in strawberry fruits.

    • Authors: S. R. Kolle; T. H. Shankarappa; Y.-S. Ho
      Pages: 133 - 145
      Abstract: In this paper, we have analyzed the characteristics of 781 highly cited articles in the Science Citation Index Expanded of category of horticulture published from 1961 to 2014. A total of 33 journals were grouped under Web of Science category of horticulture. Article has been cited more than 100 times being published since 1961 assessed in the terms of their distribution in the journals, and citation life cycle. Further, we have evaluated performance of authors, country and institutions. The Journal Theoretical and Applied Genetics and American Journal of Enology and Viticulture were more productive journals. Most of the highly cited articles published in 1990s and 2000s, respectively. Average authors per article also kept increasing from 1960s to 2000s, respectively. University of California, Davis and Cornell University in USA were the most productivity institutions and USA and the UK were the most contributing countries. The citation life cycles of the highly cited articles indicate that majority of the highly cited articles had received less citation in their publication decade, later started to receive good number of citations.

      Pages: 147 - 154
      Abstract: This study aims to determine adoption level of farmers to integrated pest management (IPM) program and also to analyse the agricultural pesticide usage in apple growing. The primary data includes a research carried out through a questionnaire method which was conducted to apple producers in Antalya, Denizli, Isparta, Karaman, Konya and Niğde. According to the information received from the survey farms were separated into four groups according to IPM adoption level. It has been found out that the amount of pesticides used per hectare decreases according to the adoption of integrated pest management. While 1 kg apple cost found USD 0.40 in farms which does not follow IPM, USD 0.38 in farms which follow IPM. However, net profit per hectare is USD 556.75 in farms which does not follow integrated pest management; it is USD 482.51 in farms which follow high level IPM. In conclusion; to implement an efficient IPM, producers primarily should take cultural precautions and in the last resort they should look for chemical methods. They should avoid extreme use of nitrogenous fertilization, they should use high quality saplings, create a suitable ecological infrastructure and habitat management to conserve natural enemies of pests, select environment friendly pesticides, make descriptions of natural enemies of apple pests, give trainings about how to prevent pests contamination.

  • Rootstock Induced Seasonal Changes of N, P and K Nutrient Levels in
           Satsuma Mandarin cvs. ‘Okitsu’, ‘Clausellina’ and ‘Silverhill’
    • Authors: Ercan Yıldız; Mustafa Kaplankıran; Veli Uygur
      Abstract: Rootstocks-scion relations have critical consequences about nutritional status, tree vigour, resistance to pest and pathogens, yield and yield quality. In this study, we therefore investigated seasonal variations of leaf mineral nutrient concentrations in Satsuma mandarin’s cvs. ‘Okitsu’, ‘Clausellina’ and ‘Silverhill’ budded on different citrus rootstocks under Dörtyol-Hatay, Turkey ecological conditions. Nitrogen (N), phosphorus (P) and K (potassium) concentrations of the leaves showed slightly similar trend each other, in general these nutrients reduced from January to March–April, and increased during the growing season until mid- and late summer, then decreased until December. Despite rootstocks did not significantly affect the leaf N, P and K concentrations rootstock-scion relation was pre-eminent and nutrient dependent. Most conspicuous scion dependent changes were recorded for K concentration whereas P concentration was little influenced. In terms of scion-rootstock combination, the range of N and K concentrations were 2.11% (‘Okitsu’/sour orange) to 2.34% (Silverhill/sour orange), and 1.09% (‘Okitsu’/Carrizo citrange) to 1.39% (‘Clausellina’/Carrizo citrange), respectively; but P concentrations were highly similar %0.13 (‘Okitsu’/sour orange) – %0.16 (‘Clausellina’/Carrizo citrange), in the entire growing season. It can be concluded that there are considerable differences in nutrient uptake ability of scion-rootstock combination.

  • Responses of Hazelnut Trees to Organic and Conventional Managements in the
    • Authors: Selçuk Özmen
      Abstract: Hazelnut trees (Corylus avellana L.) give yields without any more reduction under dryland. However, it is not known how plant water status and gas exchanges response to organic management under the dryland. In an attempt to answer this question, such responses, which are leaf water potential (LWP), stomatal conductance (gs) and photosynthetically active radiation (PAR) of hazelnut trees, were studied under organic and conventional managements in the dryland conditions. It was also investigated possible effects of those parameters on organic and conventional hazelnut trees vs. SWC and atmospheric stress (i. e., air vapour pressure deficit-VPD). Organic hazelnut trees had slightly higher ET and yield, and lower SWC than conventional hazelnut trees. However, generally, slightly higher LWP and gs values were obtained for conventional hazelnut trees while the value of VPD was higher in organic hazelnut orchards. LWP, PAR, gs response to SWC and VPD and relationships between each others were generally imperceptibly higher in organic hazelnut trees than conventional hazelnut trees but no stronger responses and relationships. Plant canopy measurements were mostly parallel with the results obtained values of ET, yield, SWC and VPD. Precipitation during the year influenced both hazelnut orchards managements to have higher yield and keep life alive. However, it could be emphasized that hazelnut trees under organic and conventional hazelnut managements required supplement irrigation to avoid summer water stress, and for providing fruit fulling and accumulation of reserves for the following year. Finally, it can be conclude that organic farming is a good alternative for hazelnut orchards in dryland.

    • Authors: Sara Agnolet; Flavio Ciesa; Evelyn Soini; Anna Cassar; Aldo Matteazzi; Walter Guerra; Peter Robatscher; Alberto Storti; Sanja Baric; Josef Dalla Via; Michael Oberhuber
      Abstract: Apple is one of the most widely produced and consumed fruits worldwide and hence, complete data of apple composition are important for human diet. Currently, a limited number of cultivars dominate the market, while many others, with a potentially higher nutritional value, are neglected by consumers. The present work reports the content of the dietary elements potassium (K), phosphorus (P), calcium (Ca) and magnesium (Mg) as well as the content of the macroelement nitrogen (N) of 34 old cultivars grown at the same site under identical conditions in South Tyrol, Italy. Their elemental composition was assessed along with quality parameters such as fruit weight, firmness, and soluble solid content and total acidity at harvest and post storage. For selected cultivars the measurements were performed over two or even three different harvest years. Comparison with eight commercial cultivars chosen to represent the fruit currently dominating the market was performed. Besides offering a valuable insight in the variation of dietary elements among old and commercial apple cultivars in up to three harvest years, this study, that complements current nutritional databases, recommends several old cultivars with high content of dietary elements for further study and eventual re-introduction in niche markets.

  • Genetic Identification and Conservation of Local Turkish Grapevine ( Vitis
           vinifera  L.) Genotypes on the Edge of Extinction
    • Authors: Ali Sabir; Hatice Ikten; Nedim Mutlu; Duygu Sari
      Abstract: In the second half of the nineteenth century, intensive renovation of vineyards took place due to the losses caused by phylloxera and local varieties were mostly replaced by several worldwide cultivars. Shift in genotypic structure in favor of modern cultivars resulted in the decrease or even disappearance of regionally typical local varieties. A total of sixty five Turkish grape genotypes, including 5 references (four cultivars and one rootstock), were genotyped with 16 SSR and 15 SRAP markers. Sixteen SSR primers generated a total of 60 SSR amplicons in which 43 were polymorphic with 73.4% average polymorphism percentage. A total of 111 well-resolved clear DNA bands were obtained from 15 SRAP primers. Of these bands, 53 were highly polymorphic with an average of 47.74%. Cluster analysis based on pooled marker data generated a well resolved grouping pattern. The analyzed genotypes grouped basing on their geographical belongings. There were many cultivar pairs on the dendrogram most of which occurred between 0.75 and 0.90 levels. SSR and SRAP data revealed a wide genetic variability as well as certain synonyms among the historical grape varieties cultivated for decades in local vineyards lengthwise the mountainous regions of Konya, Karaman and Mersin provinces. All the genotypes have been maintained in a grapevine germplasm glasshouse. Preservation and use of these endangered genotypes will be helpful to avoid genetic erosion and diversity loss in this part of Turkey. Also, the molecular data generated in this study could be of great use in determining the optimal breeding strategies to allow continued progress in grapevine breeding.

  • A Pragmatic Approach for Obtaining Lines Possessing Desirable Traits
           in Silk Banana
    • Authors: A. A. Waman; P. Bohra; B. N. Sathyanarayana; S. C. Chandrasekhar; B. L. Divya
      Abstract: Silk Banana is amongst the most popular groups of bananas grown in different parts of the world. However, the commercial scale cultivation requires identification of superior genotypes with desirable attributes including growth, yield, quality and resistance to Panama wilt disease which is a major concern. Panama disease caused by the fungus Fusarium oxysporum f. sp. cubense has been wreaking havoc in banana plantations throughout the world. A large number of varieties fall prey to the pathogen and hence world’s banana production has been threatened to a considerable extent, Silk Banana being the most vulnerable. Long term use of chemicals has not only failed to provide protection against the disease but has also raised concern about the environmental health. Resistance breeding is thus only viable alternative; however, breeding in banana is hindered by a number of inherent problems. In this communication, a systematic approach was proposed taking a typical case of Silk Banana var. Nanjanagud Rasabale to preselect lines possessing Panama wilt resistance and other desired traits. The proposed methodology comprised of identification of spontaneous variants in growing regions of the variety and their subsequent screening using a multi-pronged strategy. A number of lines exhibiting superiority in terms of tolerance to panama wilt, precocity, plant stature, physicochemical and shelf life related attributes have been reported. Considering overall performance, six promising lines were identified. This methodology has wider applicability as it could be effectively exploited with suitable modifications for identifying lines with desired traits in other varieties of banana.

    • Authors: Bunyamin Demir; Feyza Gurbuz; Ikbal Eski; Zeynel Abidin Kus; Kadir Uğurtan Yilmaz; Sezai Ercisli
      Abstract: Data mining is used as a popular technique in several scientific researches. In agriculture, application of data mining is a relatively new approach. One of the most popular data mining approaches is to find prediction rules from experimental data sets. The present study was conducted in two stages to find out a rule for estimation of width of stalk cavity, depth of stalk cavity, width of eye basin and depth of eye basin of different apple varieties (‘Amasya’, ‘Starking’, ‘Granny Smith’, ‘Pink Lady’, ‘Golden Delicious’ and ‘Arapkızı’) based on physical properties and to propose an equation for calculating these parameters. In the first stage, data processing was performed and in the second stage, Find Laws was used for prediction of apple properties. Current results revealed that data mining technique had a superior performance and could reliably be used in estimation of physical characteristics of agricultural products. Further research is recommended for possible use of datamining in other agricultural application.

  • Apfel oder Acai: Brasiliens Obstbau im ökonomischen und klimatischen
    • Authors: M. Blanke
      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.

  • Physico-Chemical Profiling of Promising Sweet Orange Cultivars Grown Under
           Different Agro-Climatic Conditions of Pakistan
    • Authors: Syed Bilal Hussain; Muhammad Akbar Anjum; Sajjad Hussain; Shaghef Ejaz; Maqsood Ahmed
      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.
