  • Biodiversity and Landscape Use of Sea Buckthorn ( Hippophae rhamnoides L.
           ) in the Coruh Valley of Turkey
    • Abstract: Abstract The Sea buckthorn, one of the most important wild edible fruits widely grown in Northeastern part of Turkey, is characterized by resistance to hard environmental conditions and looks spectacular, especially in autumn and winter when it is decorated with orange berries. Climatic conditions in Northern Anatolia are suitable for the growing of the Sea buckthorn, which can be encountered in various dry areas as well as by riversides. Local people traditionally processed or preserved sea buckthorn fruits (berries). The decorative sea buckthorn shrubs/trees and berries are an important element of natural landscape in Northeastern Anatolia. The aim of the study was to define the biodiversity among trees/shrubs, berries and leaves of the Sea buckthorn accessions based on morphological and biochemical data. Results showed a high diversity among accessions in terms of plant, leaf and berry characteristics. Berry diameter, length and 100 berry weight ranged from 5.48 to 7.18 mm; 6.64 to 9.14 mm and 15 to 26 g, respectively. A wide variability of berry skin colour was observed to be yellow, light yellow, dark yellow, yellow orange, orange and dark orange. The anthocyanin content varied from 7 to 38 mg/l berry juice.

  • Key Phenological Events, their Practical Implications and Effect of Bunch
           Age on Physico-Chemical and Postharvest Attributes in Ney Poovan Banana (
           Musa AB)
    • Abstract: Abstract Banana, one of the major staple food crops of the world, flowers round the year irrespective of the season. It gives the decisive flexibility to the grower for planning orchard operations as well as exploring the best marketing opportunities for the produce well in advance. Being a heavy feeder of nutrients and water, these inputs are critical to the success of banana cultivation especially at reproductive stage. Also, banana fruits are sensitive to many biotic and abiotic stresses which render them unsuitable for marketing. All these factors could be taken care of if phenological cycle of the crop is known to the grower. In Ney Poovan (Musa AB) banana, 58 plants were studied for parameters like days taken for floral initiation, anthesis, completion of female phase, fruit filling and total crop duration using BBCH scale. Inflorescence appeared after 311 days of planting and duration of reproductive stage varied between 124–147 days with average crop duration of 443 days. An account of the practical implications of this study has been discussed in detail. Further, another study was conducted in order to study the changes in the quality and storage behavior of the fruits harvested at different phases of bunch development (12–18 weeks after anthesis). Studies revealed that fruits harvested after 16 weeks of anthesis were more firm, exhibited maximum shelf life with minimum PLW and had highest TSS content amongst all the groups studied. The early as well as delayed harvesting rendered the fruits inferior in most of the parameters studied.

  • Elliptic Fourier analysis for shape distinction of Turkish hazelnut
           cultivars
    • Abstract: Abstract Shape is a crucial physical property of agricultural products and hence is an important parameter for assessing the quality standard. In the present study, shape variations among 17 hazelnut cultivars grown in Turkey were revealed from their digital images using shape descriptors obtained from elliptic Fourier analysis (EFA), which is a shape-based methodology. Subsequently, principal component analysis (PCA) was performed to summarize the variations among the hazelnut cultivars. This was followed by linear discriminant analysis using the first four principal components, representing 93.9 % of the total variance, obtained from the PCA to discriminate the 17 hazelnut cultivars. Estimates of Hotelling’s pairwise comparisons from the multivariate analysis based on the shape variables obtained from the EFA revealed ideal shape differences between the hazelnut cultivars. Hierarchical cluster analysis divided the cultivars into six clusters according to their shape characteristics. In addition, size (projected area, length, width, thickness, surface area, geometric mean diameter), shape (shape index, sphericity, roundness, and elongation), and gravimetric (mass and volume) features of the 17 common hazelnut cultivars were also determined via an image processing technique.An analysis of variance was performed to test the differences among these variables in a descriptive method. We found that EFA provided excellent discrimination between the hazelnut cultivars with respect to their shape features.

  • Biodiversity of figs ( Ficus carica l.) in Coruh valley of Turkey
    • Abstract: Abstract The Coruh valley lies within the Caucasus ecological zone, which is considered by the World Wild Fund for Nature and by Conservation International as a one of the biodiversity hotspot in the world. The valley is also recognized by Turkish conservation organizations as an important plant area, an important bird area, a key biodiversity area and has been nominated as a high priority area for protection. This valley is rich in plants and contains 104 nationally threatened plant species of which 67 are endemic to Turkey. Fig (Ficus carica L.) is one of the most important wild edible fruit tree along with pomegranate and olive in the valley. Figs have been used for fresh consumption for centuries and also an important element of natural landscape of the valley. The valley abundantly has black, purple and yellow-green fruited fig trees. In this study we determined some important tree, leaf and fruit morphological characteristics of 50 selected wild grown fig accessions naturally found in the valley. The results showed that the investigated morphological traits of fig accessions displayed significant differences each other. Principal coordinate analysis showed that diversity among the accessions was high and the accessions had black and yellow-green colored fruits were the most diverse groups.

  • Determination of Heat Requirements and Effective Heat Summations of Some
           Pomegranate Cultivars Grown in Southern Anatolia
    • Abstract: Abstract Temperature (high and low) is one of the most limiting environmental factors for growth and production of fruits in different parts of the world. For temperate-zone fruit species, a certain total heat requirements are needed in order to obtain ripe fruits. The aim of this study was to determine heat requirements of three commercial pomegranate cultivars (‘Suruc’, ‘Katirbasi’ and ‘Hicaznar’) grown in Southern Anatolia region. The cultivars showed a narrower range of heat requirements for flowering (growing degree hours, GDH), i.e. ‘Suruc’ (25,000), ‘Katirbasi’ (25,270), ‘Hicaznar’ (28,000) and a wide range of heat requirements for fruit ripening, i.e. ‘Suruc’ (73,670), ‘Katirbasi’ (74,105) and ‘Hicaznar’ (88,052) GDH. Under the Sanliurfa province conditions, two years average of effective heat summation requirement from bud swelling to 50 % flowering stage for ‘Suruc’, ‘Katirbasi’ and ‘Hicaznar’ cultivars are calculated as 643, 655 and 718 growing degree days (GDD) and from bud swelling to harvest are 2734, 2802 and 3289 GDD. It can be concluded that the effective heat summation of Sanliurfa province is enough for commercial growing for all pomegranate cultivars.

  • Polyphenolic Compounds and Antioxidant Activity in Berries of Four Russian
           Cultivars of Lonicera kamtschatica (Sevast.) Pojark
    • Abstract: Abstract Nowadays increasing attention has been focused on polyphenolic compounds as the main representants of antioxidants in horticultural crops including fruits. The edible honeysuckle has an unique position among lesser known fruits due to its high level of antioxidants. In the present study we determined polyphenolic profile and antioxidant capacity of four Russian cultivars of edible honeysuckle including ‘Gerda 25’, ‘Amfora’, ‘Morena’, ‘Lipnicka’, which found together in a single location in Mendel University in Brno, The Czech Republic. Polyphenolic compounds were detected by high performance liquid chromatography coupled with electrochemical detector (HPLC-ED). The antioxidant capacity was measured by DPPH test. According to the results there were differences among cultivars in terms of polyphenolic content and antioxidant activity and Lonicera kamtschatica ‘Gerda 25’ were found to be possessed the highest content of phenolic compounds corresponding to the highest value of antioxidant activity.

  • Some Physicochemical Characteristics, Bioactive Content and Antioxidant
           Characteristics of Non-Sprayed Barberry ( Berberis vulgaris L. ) Fruits
           from Turkey
    • Abstract: Abstract Increasing consumer demands for indigenous, non-sprayed with pesticides and less-known or “forgotten” fruits necessitate knowledge on their breeding, cultivation, biochemical content, harvesting and marketing. Anatolia is rich for wild edible fruit species and barberry is abundant throughout Anatolia. The aim of this study was to determine some important physicochemical characteristics, bioactive content and antioxidant capacity of fruits from nineteen promising barberry (Berberis vulgaris L.) genotypes grown in the Coruh valley, Northeastern Anatolia. The results indicated genotype-specific differences for most of the physicochemical characteristics, antioxidant capacity and the content of some bioactive compounds. Fruit mass ranged from 0.073 (‘Coruh-7’) to 0.267 g (‘Coruh-11’). Total phenolic content ranged from 2532 (‘Coruh-’) to 3719 mg GAE per liter fruit juice (‘Coruh-11’). The genotype ‘Coruh-12’ had the highest total monomeric anthocyanin content (1004 mg per liter fruit juice) as cyanidin-3-glucoside. The highest total antioxidant capacity was observed in fruits of ‘Coruh-8’ and ‘Coruh-9’ genotypes with all three antioxidant-determining methods. We conclude that the barberry fruits represent a good source of bioactive phytochemicals because of their high phenolic and anthocyanin contents.

  • Biology and control of the apple canker fungus        class="a-plus-plus">Neonectria ditissima (syn.
           N. galligena) from a
           Northwestern European perspective
    • Abstract: Abstract A review of apple canker caused by Neonectria ditissima is presented for Northwestern Europe with a focus on the Lower Elbe region (Northern Germany). Whereas conidia released by rainsplash are produced mainly from spring to autumn, the liberation of wind-borne ascospores peaks in autumn and/or early spring. Infection occurs via natural as well as pruning-induced wounds, some of which are present throughout the year. Autumnal leaf scars are the most frequent entry point for N. ditissima. Wounds on tree trunks, especially bark cracks in the crotch regions, are potentially even more serious because cankers on trunks and leader shoots commonly cause the total loss of a tree. Surface moisture is a prerequisite for leaf scar infections but possibly not for an entry through other wounds. Irrespective of the entry route, successful infection of a wound requires a mass inoculum of at least 50–100 conidia or ascospores. Infections of trees originating in nurseries may enter a state of latency from which they can break out up to 3 years after the trees have been explanted into the production orchard. Streaks of brown wood discolourations can be caused both by systemic colonisation of the xylem by N. ditissima and by winter frost damage. Apple varieties may show pronounced differences in their sensitivity to canker. For highly susceptible varieties, this disease can be a major production-limiting factor. Flower infections by N. ditissima commonly lead to a pre-harvest rot at the blossom end of the fruit, whereas infections of the growing fruit before harvest lead to a storage rot. Rigorous pruning is an essential canker control measure. Chemical control during the growing season is achieved by apple scab fungicides such as dithianone, captan or dodine. At leaf fall and in winter, copper fungicides are indispensible for controlling canker on highly susceptible varieties in Northern Germany.

  • Nicht-destruktive Bestimmung der Beduftung bzw. des Duftfilmes bei
           Pflaumen
    • Abstract: Zusammenfassung Pflaumen und andere Früchte entwickeln während ihres Fruchtwachstums eine halbtransparente, weißliche Schicht auf ihrer Oberfläche, die als Beduftung oder Duftfilm bezeichnet wird. Die Beduftung auf Pflaumen verschiedener Farbe (Hauszwetsche, Reneclaude, Mirabelle) wurde mit Hilfe eines Rasterelektronen – Mikroskopes, eines Farbmessgerätes und eines industriellen Sensors, der einen Anteil des reflektierten Lichtes als sog. ‘luster level’ in 15 mm Abstand misst, nicht-destruktiv und zeitgleich – im Vergleich zu einer Farbmessung – untersucht. Wachsanalysen der europäischen Pflaumen resultierten in 175–205 µg Wachs/cm2 Fruchtoberfläche mit Linolen- und Ursolsäure als dominierende Fettsäuren. Mikroskopische Aufnahmen zeigten die natürliche epikutikuläre Oberflächenstruktur mit Wachsplättchen, die nach Polieren mit einem weichen Tuch abgeschwächt wurde. Mit Hilfe des Luster-Sensors wurde es möglich, Veränderungen der Beduftung bzw. der natürlichen Bewachsung nach Polieren zu bestimmen; sie führten zu einer Verdoppelung der ‘luster level’ von 120–170 auf 300–500 Luster-Einheiten und damit zu einem klaren Ergebnis bzw. Abgrenzung beider Oberflächenzustände gegeneinander, die beim Polieren weniger auf Wachsabrieb, sondern eher auf Wachsumverteilung und –umstrukturierung zurückzuführen sind. Durch Polieren stieg der a-Wert im Lab Farbraum geringfügig von 2,35 auf 2,85 an, während der b-Wert von − 14 stark auf − 5 anstieg, d. h. der optische Farbeindruck wird durch das Verändern der Wachskristalle auf der Pflaumenoberfläche stärker blau. Obwohl die Beduftung der Hauszwetsche durch ihren dunkelblauen Hintergrund optisch besser sichtbar ist als bei den gelben Mirabellen und grünen Renecloden, war sie mit diesem optischen Glanzsensor genauso gut nicht-destruktiv messbar und somit genauer als bei Messung der Fruchtfarbe mittels eines optischen Farbmessgerätes. Diese Ergebnisse lassen sich vermutlich auch auf andere Früchte mit vergleichbarem Wachsfilm wie z. B. rote Weinbeeren und Heidelbeeren übertragen und z. B. auf einer Sortierstraße oder mit einem Handgerät schnell, einfach und preiswert Glanzgrad bzw. Intensität des Handlings nach Abreiben der Oberflächenwachse bestimmen.

  • Das Potential von Apfel-Birne-Hybriden für die Kernobstzüchtung
    • Abstract: Zusammenfassung Hybriden von Apfel und Birne wurden bereits verschiedentlich durch klassische Züchtung erzeugt und beschrieben, allerdings haben bisher keine vitalen und fertilen Hybriden Eingang in die Kernobstzüchtung finden können. Kürzlich haben die Autoren die von M. Zwintzscher in den 80er Jahren erzeugte putative Hybride untersucht und konnten auf genetischer, physiologischer und phänotypischer Ebene ihren Hybridcharakter bestätigen. Anders als im Fall anderer Hybriden gelang mit Zwintzscher’s Hybride als mütterliche Linie durch H. Schimmelpfeng in den 90er Jahren bereits die Züchtung von fünf F2-Hybrid-Pflanzen. Diese sind auch schon blühfähig, fruchten regelmäßig und drei der F2-Linien könnten sogar selber Sortenpotential besitzen. Durch die Existenz dieser vitalen und fertilen Hybriden bietet sich die Gelegenheit, über diese F2-Linien verschiedene Anteile des Birnen-Genoms und damit interessante neue genetische Faktoren auf klassischem Wege in das Apfel-Genom einzukreuzen und damit für die Apfelzüchtung verfügbar zu machen. Mit Teilen des Birnen-Genoms könnten Nicht-Wirts-Resistenzen der Birne gegen Apfel-spezifische Pathogene wie den Apfelschorf (Venturia inaequalis) oder auch neue Aroma-Biosynthese-Gene eingekreuzt werden. Ein neues Projekt zur Züchtung einer entsprechenden F3-Generation wird hier vorgestellt.
