  • Effects of Plant Growth Promoting Rhizobacteria (PGPR) on Growth, Yield
           and Fruit Quality of Sour Cherry ( Prunus cerasus  L.)
    • Authors: Şeyma Arikan; Lütfi Pirlak
      Pages: 221 - 226
      Abstract: Abstract The sour cherry cv. ‘Kütahya’ is one of the most produced cultivars in Turkey. This study was conducted with cultivar ‘Kütahya’ cultivated on Prunus mahalep both 2010 and 2011 years. In this study, the effects of Bacillus mycoides T8 and Bacillus subtilis OSU-142 bacteria strains on yield, fruit properties and plant growth was aimed to investigate. Floral and foliar applications of T8, OSU-142 and T8+OSU-142 on sour cherry significantly increased the yield per tree, shoot length and leaf area, compared with the control. The highest shoot length was found in the T8+OSU-142 (51.74 cm) application while the least value was found in the control (46.71 cm). The yield increased from 8.229 kgtree−1 (in control) to 13.663 (T8 application) and to 11.660 kgtree−1 (T8+OSU-142 application) in average of two years. The results of the present study suggested that Bacillus T8 and Bacillus OSU-142, alone or in combination, have a great potential for the enhancement of yield and plant growth of sour cherry and therefore they have been suggested in growth promotion in sour cherry cultivation.

  • Effects of Preharvest Foliar Calcium Applications on the Storage Quality
           of ‘0900 Ziraat’ Sweet Cherry Cultivar
    • Authors: Neslihan Ekinci; Funda Özdüven; Engin Gür
      Pages: 227 - 231
      Abstract: Abstract The objective of this study was to investigate effects of foliar calcium application on storage of sweet cherry. Different concentrations of CaCl2 (2.4, 3.2, and 4.0 g/l) and Ca(NO3)2 (3.4, 4.6, and 5.8 g/l) were applied six times by foliar spraying on leaves and fruits of the sweet cherry variety ‘0900 Ziraat’. Harvested fruits were packaged in 500 g plastic boxes and stored for four weeks at 0 0C and 90–95 % relative humidity. During the experiment, flesh firmness, titratable acidity value (TA), pH, total soluble solids content (SSC) ratio, and weight losses were weekly assessed. The results indicated that there were positive effects of foliar calcium applications on fruit quality coupled with improved firmness, and enhancement of TA, an additional advantage for consumer acceptability. It was found that lower concentrations of both calcium treatments were not affective. On the other hand, 3.2 g/l calcium chloride and 4.6 g/l calcium nitrate were advised. Higher concentrations (4.0 g/l calcium chloride and 5.8 g/l calcium nitrate) caused a decrease in fruit quality through deformations on the fruit surfaces, especially after the third week of storage.

  • The Determination of Nematode Tolerance and Seedling Performance of The
           Selected Almond ( Prunus amygdalus  L.) Genotypes in Isparta Province
    • Authors: M. Fatih Kızıltan; Adnan Nurhan Yıldırım; M. Ali Söğüt
      Pages: 233 - 239
      Abstract: Abstract In the present study, selected almond genotypes in Keciborlu/Isparta region by Yıldırım (2007) based on late blooming and superior nut chacteristics were used to evaluate seedling growth performances and the reaction to root knot nematodes. Seeds were planted on perlite medium and stored 60 days at +4 °C in order to break seed dormancy. After germinating, seedlings were transferred to plastic pots to evaluate seedling growth characteristics and remaining seedlings were inoculated with Meloidogyne javanica and Meloidogyne incognita in order to asses resistance status of the selected seedlings. The highest germination percentage was obtained from Genotype 54 (96.1 %), the highest plant was observed from Genotype 9 (62.18 cm), the longest primary root was found from Genotype 54 (30.28 cm), the average secondary root lenght was highest in Genotype 9 (31.04 cm) and the widest root collar was observed in Genotype 33 (8.38 mm). Seedling stem diameter changed between 4.76 mm (Genoype 40) to 7.67 mm (Genotype 33). The lowest variation for stem widht was observed in Genotype 55 (0.58 %) while the lowest variation for seedling hight was found in Genotype 33 (0.50 %). Evaluated almond genotypes showed different reactions to studied nematode species, M. javanica and M. incognita. Resistant reactions of almond genotypes to nematode species were classified as susceptible, tolerant and resistant based on gal index values. Genotype 9 and 31 classified as tolerant to M. javanica while Genotype 54 classified as resistant to M. incognita.

  • Variation in Total Phenolic Compounds, Anthocyanin and Monoterpene Content
           of ‘Muscat Hamburg’ Table Grape Variety ( V. vinifera L.) as Affected
           by Cluster Thinning and Early and Late Period Basal Leaf Removal
           Treatments
    • Authors: D. Kok
      Pages: 241 - 246
      Abstract: Abstract Cluster thinning (CT) and basal leaf removal (BLR) are common canopy management practices used in grape growing. In recent years, novel viticultural techniques have been evolved all around the world to decrease costs of yield management, causing improvement in grape quality. The purpose of this study was to evaluate the effects of CT and early and late period BLR treatments on yield and quality components of cv. ‘Muscat Hamburg’. While BLR treatments were performing at pre-bloom (PB, early), berry set (BS), berries with pea size (PS), verasion (V), CT treatment was conducted at verasion period. Compared to Control, while the total phenolic compounds content, total anthocyanin content, free volatile terpenes content and potentially volatile terpenes content were made better by CT treatment and BLR treatments applied from berry set to verasion period gradually raised all these quality components. As a result, BLR-PB treatment from BLR treatments, which was alternative to usual cluster thinning treatment in yield controlling grapevines was especially determined as powerful tool for improving quality characteristics of cv. ‘Muscat Hamburg’.

  • Morphological Variability of Berberis integerrima from Iran
    • Authors: Abbasali Jannatizadeh; Abdollah Khadivi-Khub
      Pages: 247 - 252
      Abstract: Abstract Barberry is a valuable medicinal plant that belongs to family Berberidaceae. In the current research, phenotypic variations of 34 individuals of wild barberry (Berberis integerrima) were evaluated. Significant phenotypic diversity was detected between the studied accessions based on morphological traits. Significant correlations were found for variables related to seed and berry, so that seed quantity, seed width, seed weight and seed length were positively correlated with berry quantity, berry weight, skin bloom and berry length, respectively. Leaf length was in significant positive correlation with berry shape, berry skin bloom, seed length, and seed weight and in negative correlation with seed quantity. Principal component analysis showed that 77.75 % of the phenotypic variability was explained by all components for the studied individuals. Variables such as seed length, width and weight, berry length and weight, spine length, leaf length, berry quantity, and seed quantity were predominant in the first three components and contributed most of the total variation. The present results have an important implication for characterization, improvement and conservation of barberry germplasm.

  • Seedless Berry Growth and Bioactive Compounds of cv. ‘Recel Uzümü’ (
           V. Vinifera L.) as Affected by Application Doses and Times of Pre-Harvest
           Thidiazuron
    • Authors: Demir Kok; Erdinc Bal
      Pages: 253 - 258
      Abstract: Abstract The purpose of this research was to appreciate the impact of the synthetic cytokinin, well known as thidiazuron (TDZ) on seedless berry quality of cv. ‘Recel Uzümü’. Three concentration levels including 0, 5 and 10 mg/L were applied on the grapevines during different phenological stages of grapevine such as Time 1: beginning of berry stetting, Time 2: berries pepper corn size and Time 3: berries pea size. While TDZ application times had no impacts on cultivar characteristics, it was determined that the application doses of TDZ had major impacts on yield and quality components of cv. ‘Recel Uzümü’. Consequently, ascending TDZ doses increased berry and cluster size and led to decreases in total soluble solids content, total phenolic compound content, total anthocyanin content and p-value of grape juice regardless of TDZ application time. The most effective TDZ dose was 10 ppm for improving berry and cluster size in cv. ‘Recel Uzümü’.

           ISSR and RAPD Analysis
    • Authors: Ozgun Kalkışım; Melih Okcu; Zuhal Okcu; Besim Karabulut; Nalan Yildirim; Guleray Agar
      Pages: 259 - 264
      Abstract: Abstract Thirty one pears genotypes from east blacksea region were evaluated for genetic relationships by using Randomly Amplified Polymorphic DNA (RAPD) and ISSR (Inter-Simple Sequence Repeats) markers from total 70 RAPD and ISSR primer investigated, 22 could amplify clearly and consistently. Cluster analysis of the pears genotypes was performed based on data from polymorphic bands RAPD and ISSR by using Jaccard’s similarity coefficient and the Unweighted pair-group method with arithmetic average (UPGMA) clustering method. The 31 pear genotypes were classified into two major groups. Cluster A was divided into 2 subclusters: Gumushane pears and Trabzon pears. Cluster B consisted of Artvin pears. The similarity matrix values ranged between 0.105 and 0.968.

  • Cherry 2016 – Abschlusskonferenz des EU Projektes COST Cherry FA 1104 im
           Anbaugebiet der Tragana Rodochori-Kirsche in Nordgriechenland
    • Authors: M. Blanke
      Pages: 265 - 268
      Abstract: Zusammenfassung Die Abschlusskonferenz des vierjährigen COST Cherry FA 1104 Projektes fand in Griechenland statt, dem nach Polen, Italien und Spanien viertgrößten Kirschproduzenten der EU. Höhenlagen um 600 m sorgen in Makedonien (40°N) für ausreichend Kältestunden (1200 Chilling Hours), um die frühe Blüte bereits Anfang April zu induzieren; Honigbienen dienen zur Bestäubung. Die Kirschen reifen vom 25. Mai bis 15. Juni und werden auf fruchtbarem Boden ohne Frostschutz und ohne Folientunnel sowohl mit Lokal – als auch internationalen Sorten und früher großen Bäumen, heute auf Gisela 6 oder Piku angebaut. Lokale Baumschulen sorgen für Pflanzmaterial und Gewebelabors für Mikrovermehrung der Kirschunterlagen. Vor 50 Jahren – 1961 – wurde aus der ehemaligen Rebschule in Naoussa das Obstbauinstitut zur Forschung und Fortbildung gegründet, das sich seit 1970 auch mit Kirschen beschäftigt. Von den 60.000 t Kirschernte werden 13–17 % (8–10.000 t) vornehmlich nach Europa bzw. bis zum Embargo bzw. bis einschl. 2014 6000 t nach Russland exportiert. Diese Premiumware für den Export wird z. T. aufwendig von Hand ausgedünnt und erzielt Abgabepreise von 2–3 €/kg bei Vermarktung einer Genossenschaft in Naoussa als „Tragana-Kirschen aus Rodochori“, einer von der EU geschützten Herkunftsbezeichnung.

      Abstract: Abstract Hazelnut (Corylus avellana L.) is mostly grown in rainfed condition in Turkey as well as other some countries in the world without more yield reduction. However, there is not enough information about how to give yield without more reduction in rainfed hazelnut orchard. In an endeavor to search this question, quantifications of leaf water potential (LWP), stomatal conductance (gs) and photosynthetically active radiation (PAR) of hazelnut tree were investigated in rainfed hazelnut orchard in the summer of 2013 and 2014. Additionally, possible effects of those quantifications on rainfed hazelnut trees vs. soil water content (SWC) was investigated. Results of this study exhibited that yearly ET (evapotranspiration) of rainfed hazelnut trees was higher in 2014 than 2013 even though seasonal ET of rainfed hazelnut trees was higher in 2013 than 2014. Hence, yield, LWP and gs were higher in 2014 than 2013 but PAR and SWC (even all the study season) were mostly higher in 2013 than 2014. Moreover, relationships of LWP, gs and PAR and responses of LWP, gs and PAR to SWC were non stronger. These differences could be attributed differences of climate variability such as precipitation and temperature during the observed period throughout the season in the studied years. However, rainfed hazelnut trees may be required supplement irrigation in dry summer, such as year of 2013, to avoid summer water stress. Finally, it can be concluded that hazelnut trees can be grown well and give normal yield for the areas which have about 950 mm precipitation.

  • EUFRIN Tagung in Porto 2016 – Themen von Ausdünnung
           bis Stippigkeit
    • Authors: M. Blanke
      Pages: 281 - 283
      Abstract: Zusammenfassung Der Beitrag berichtet vom diesjährigen Treffen der EUFRIN-Ausdünngruppe in Porto im März 2016 mit folgenden Ergebnissen 1) Die Mehrzahl der Vorträge beschäftigte sich mit dem neuen Ausdünnprodukt BrevisTM zur Fruchtausdünnung im 8–10 mm Stadium bei Apfel (und Birne); die Wirkung beruht auf einer Photosynthesehemmung; die Zulassung ist in den meisten europäischen Ländern bereits erfolgt oder beantragt. 2) In Vorversuchen wurde die Ethylenvorstufe ACC (1‑Aminocyclopropancarbonsäure) zur Ausdünnung sowohl von Kern- als auch Steinobst auf 3 Kontinenten erprobt. Im späten 18–20 mm Fruchtstadium, nach der empfindlichen Zeit für Berostung, führte ACC bei Apfel zu dem gewünschten Fruchtfall verbunden mit leichtem Blattfall, einer Photosynthesehemmung in Abhängigkeit von der Konzentration und einer Alternanzbrechung. 3) In einem ersten, einjährigen Experiment an der Cornell Universität erhöhte S-ABA (Abscisinsäure) den Calciumgehalt der Frucht von 3 auf 5 mg/100 g FM und verminderte damit die Stippigkeit bei der amerikanischen Clubsorte ‘Honeycrisp’. Allerdings waren dazu 5 Anwendungen in 10-tägigem Abstand nach der Blüte notwendig und damit relativ aufwendig und teuer und sowohl mit leichten Blattvergilbungen, in Abhängigkeit von der Konzentration von S‑ABA, als auch mit 10–15 % kleineren Früchten verbunden. Weitere Forschungsergebnisse werden zeigen, welche Versuchsmittel sich für unsere Sorten und unser Klima eignen und dann auch zur Registrierung kommen.

  • Highly Cited Articles in Science Citation Index Expanded – Subject
           Category of Horticulture: A Bibliometric Analysis
    • Authors: S. R. Kolle; T. H. Shankarappa; Y.-S. Ho
      Abstract: 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.

  • Forecasting Apple Fruit Color Intensity with Machine Learning Methods
    • Authors: Blaž Germšek; Črtomir Rozman; Tatjana Unuk
      Abstract: 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%.

  • Antioxidant Compounds, Nutritional Quality and Colour of Two Strawberry
           Genotypes from Fragaria  × Ananassa
    • Authors: Violeta Nour; Ion Trandafir; Sina Cosmulescu
      Abstract: 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.

  • 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
      Abstract: 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.

  • Effect of Different Treatments on Branching of Some Apple Trees in Nursery
    • Authors: Muzaffer İpek; Şeyma Arikan; Lütfi Pirlak; Ahmet Eşitken
      Abstract: 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.

           Turkey
    • Authors: Nurgül Türemiş; Lütfi Pirlak; Ahmet Eşitken; Ümmügülsüm Erdoğan; Aytaç Tümer; Burhanettin İmrak; Ayşegül Burğut
      Abstract: 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.

           Humic Acid Applications on Vegetative Growth of Sweet Cherry ( Prunus
           avium  L.)
    • Authors: Sabahittin Abay; Lütfi Pirlak
      Abstract: Abstract This study was carried out in İscehisar district of Afyonkarahisar on ‘0900-Ziraat’ sweet cherry cultivar for two successive years in 2011 and 2012. Ten different applications consisting of 80 g FeSO4.7H2O tree−1, 20 g FeEDDHA tree−1, 420 mL TKİ-Hümas tree−1, 80 g FeSO4.7H2O + 420 mL TKİ-Hümas tree−1, 200 g powder sulphur (S) tree−1, 80 g FeSO4.7H2O + 200 g powder S tree−1, 25 g ZnSO4.7H2O tree−1, 25 g ZnSO4.7H2O + 420 mL TKİ-Hümas tree−1 and 25 g ZnSO4.7H2O + 200 g powder S tree−1 were subjected for determination of their effect on vegetative growth of sweet cherry. In this study, shoot diameter, shoot length, leaf total chlorophyll content, leaf area and leaf iron (Fe) and zinc (Zn) contents were obtained. Shoot length, shoot diameter and leaf area showed general increases in 80 g FeSO4.7H2O + 200 g powder S tree−1 and 25 g ZnSO4.7H2O + 200 g powder S tree−1 treatments. The results clearly indicated that he treatments had different effects on the shoot length and shoot diameter although there was a differences between the experimental years. Particularly, significantly positive effects of the treatments on leaf total chlorophyll was apparent for the second year’s observations. In addition, Fe and Zn concentrations in leaf were markedly increased in response to the treatments.

  • Nicht-destruktive Erkennung von Berostung bei Birnen
    • Authors: Matthias Klemm; Olga Röttger; Lutz Damerow; Michael Blanke
      Abstract: Zusammenfassung Ziel der Untersuchungen war es, herauszufinden, ob glatte Berostung auf Früchten mit einem Glanz-(Luster-)Sensor nicht invasiv und zeitnah erkannt werden kann – unter dem Einfluss von Sorte, Schalenfarbe und Oberflächenkrümmung, d. h. Messposition auf der konkaven Frucht. Dazu wurden Birnen dreier Sorten aus dem LEH auf dreierlei Weise untersucht, zuerst visuell auf Berostungsart und -verteilung, mit dem 3D Farbmikroskop auf Rauigkeitstiefe und Oberflächenbeschaffenheit und mit einem Glanz- bzw. Lustersensor. ‘Conference’ Birnen aus Belgien wiesen die stärkste flächige glatte Berostung im bauchigen Bereich des Kelches und fleckige Berostung am Stielende auf, ‘Alexander Lucas’ aus Deutschland kleine flächige Berostung im Bauchbereich mit sonst glatter unberosteter Schale und ‘Abate Fetel’ aus Italien flächige glatte Berostung in den oberen cm nahe am Stielansatz der Frucht. Untersuchungen mit einem 3D Farb-Mikroskop bei 200facher Vergrößerung zeigten eine 2,5 fach höhere Rauigkeitstiefe – als Maß der Unebenheit der Fruchtschale – bei den berosteten Schalenpartien der ‘Conference’ Birnen von ca. 50 µm im Vergleich zu den glatten, unberosteten Schalenarealen der ‘Alexander Lucas’ Birnen mit nur ca. 20 µm. Schwach berostete Früchte der Birnensorte ‘Alexander Lucas’ erreichten signifikant höhere und solche von ‘Abate Fetel’ tendenziell höhere Luster-(Glanz-)werte mit geringerer Streuung der Messwerte als stark berostete Früchte der gleichen Sorte. Luster-(Glanz-)werte im schmalen Halsbereich lagen etwas höher als im bauchigen Bereich der Frucht; dunkle Schalenfarbe wies höhere Lusterwerte auf als helle. Diese ersten Untersuchungen mit 180 Einzelmessungen deuten darauf hin, dass die Erkennung glatter Berostung mit diesem Sensorsystem auf einer Kombination von Farbe und Oberflächenbeschaffenheit bzw. Rauheit beruht. Weiterer Forschungsbedarf besteht. Die Ergebnisse stehen im Einklang mit denen bei Pflaumen, bei denen ebenfalls eine raue, bereifte Oberfläche geringe, aber eine spiegelnde, glatte, polierte Fruchtoberfläche höhere Lusterwerte erzeugte.
