  • Optimization of Factors Affecting In vitro Establishment, Ex vitro Rooting
           and Hardening for Commercial Scale Multiplication of Silk Banana ( Musa
    • Abstract: Abstract Factors concerning aseptic culture establishment and hardening were studied in detail in choicest Silk Banana. Effect of size of sucker (small, medium and large), carbon concentration (10, 20 and 30 g/l), season of initiation (wet and dry) and pre-treatments such as segmentation and incision to the explants were studied during initiation. Further, hardening related factors such as substrates used for primary and secondary hardening, nursery nutrition (source and frequency of application) and pre-treatments for ex vitro rooting were also studied. Results revealed that small suckers were most suited for initiations with the least contamination, maximum establishment and higher percentage of greening. Lower concentration of sucrose, though delayed greening, resulted in 100 % establishment of explants. Initiations performed during the drier period were completely free from the fungal contamination and showed less bacterial contamination than those performed during the rainy season. Segmentation of explant into four parts during first subculture supported maximum shoot proliferation by overcoming apical dominance. Coir pith was observed to be the most congenial substrate during primary hardening, whereas coir pith alone or sand: red earth: coir pith (1:1:1) supported superior performance of plantlets during secondary hardening. Single application of mono ammonium phosphate improved growth of plantlets during secondary hardening. Pre-treatment with mono ammonium phosphate gave the best response in terms of rooting and hardening of un-rooted micro-shoots. Thus, the discussed methodology could help the industries to take up commercial scale propagation of Silk Banana.

  • A Morphometric Study of Autochthonous Plum Genotypes Based on Multivariate
    • Abstract: Abstract Iran is one of the most important plum producers in the world. The present study was conducted to compare agro-morphological characteristics of 100 traditional plum genotypes in Iran. The results showed statistically significant differences between the studied genotypes and leaf dimensions, fruit shape, fruit density, fruit color and fruit flesh firmness showed the highest relative range of variation. Flowering time was extended from 25 March to 5 April and fruit ripening from late July to early August. There were high positive correlations between fruit weight and fruit dimensions and between fruit weight and leaf dimensions. Principal component analysis showed high discrimination capabilities of variables measured. Most of these variables were characters linked to fruit and leaf size. Cluster analysis grouped the studied genotypes into two main clusters with several sub-clusters. In can be concluded that fruit weight, fruit color and fruit flesh firmness are very important characteristics and probably are the first characters to be considered in a farmers selection process. The results of the current study provided information which may be useful for determining the biodiversity of autochthonous genotypes, for the purposes of obtaining guidelines in determining in situ and ex situ germplasm characterization.

  • Determination of Genetic Diversity Among Wild Grown Apples From Eastern
           Black Sea Region in Turkey Using ISSR and RAPDs Markers
    • Abstract: Abstract In this study, we investigated interspecific variations of apple genotypes using ISSR (Inter-Simple Sequence Repeats) and RAPD (Randomly amplified Polymorphic DNA) technique. Total 19 genotypes of wild grown local varieties were collected from Eastern Black Sea region of Turkey and have been studied for the analysis of ISSR and RAPD profile to examine their relationship. From total 53 RAPD and ISSR primer investigated, 28 could amplify clearly and consistently. All bands obtained from ISSR and RAPDs primer were polymorphic. The dendrogram realized from the RAPD and ISSR markers grouped the 19 genotypes into two major clusters. Cluster I comprised ‘Bey Apple’, ‘Fatty Apple’, ‘Golden Delicious’, ‘Yellow Belly Apple’, ‘Bride Apple’, ‘Green Belly Apple’, ‘Summer Apple’, ‘Yomra Apple’, ‘Tavşanbaşı’, ‘Black Belly Apple’, ‘Chest Apple’, ‘Local Marble’, ‘English Apple’, ‘Willow Apple’, ‘Arabian Girl’, ‘Yellow Hıdır’ and cluster II contained ‘Starking Delicious’, ‘Mahsusa’, ‘Amasya Marble’. Genetic diversity data from this study will be helpful in using and exploiting the wild genetic material for breeding purposes as well as for further research.

  • Economic Analysis of Pesticides Applications in Apple Orchards in West
           Mediterranean Region of Turkey
    • Abstract: Abstract The main objective of this study was to determine the amounts and types of pesticides used in apple orchards, as apples are one of the most important products of Turkey and to analyze the amount of economic losses on farm-level and costs of pesticides use in comparison with application levels used by growers and suggested in apple production by extension units and pesticide prospectus. Furthermore, the use of agricultural chemicals and practices by the growers were also determined. Production data for 2011 was collected from 114 apple producers who used pesticides. The average area of apple production was 1.43 ha with 24,274.30 kg ha−1. The average cost of apple production was € 3,736.19 ha−1. The average usages per hectare of active ingredient of insecticides, fungicides and acaricides were determined to be 13,701.60 g, 11,394.60 g and 2,152.20 g, respectively. Average plant protection costs were € 1,574.42 ha−1, which made up 42.14 % of the apple production costs. In the study area, the excessive use of agricultural chemicals was determined in the apple production. It was calculated that economic loss was € 549.71 per hectare due to overdose of agricultural chemicals. The percentages of this loss were 86.00, 0.52 and 13.47 %, due to pesticides, copper sulfate and winter and mineral oils respectively. It was calculated that the economic loss was € 472.73 per hectare due to overdose of pesticides. The percentages of this loss were 63.63, 26.70 and 9.67 % due to insecticides, fungicides and acaricides respectively.

  • Mineral Composition of Leaves and Fruit in Some Myrtle ( Myrtus communis
           L.) Genotypes
    • Abstract: Summary The mineral composition of leaves and fruits of two myrtle genotypes with yellowish-white and purple-black fruits from Çandır village (Isparta) and a genotype with yellowish-white fruits from Serik (Antalya), all of which had high fruit quality, was determined in this study. The results of the study showed that both leaves and fruits of myrtle were rich in K, Ca, Mg, and P contents. No significant correlation could be found between the fruit colors (purple-black and yellowish-white) and mineral contents of the genotypes. The highest total minerals were obtained from Genotype 11 (with purple-black fruits) for the leaf samples but from Genotype 17 (with yellowish-white fruits) for the fruit samples.

  • Möglichkeiten zur Verbesserung der Rotfärbung bei Äpfeln
    • Abstract: Zusammenfassung Das vorliegende Übersichtsreferat gibt einen Überblick über die beiden Forschungsansätze a) Intensivierung der bereits vorhandenen roten Deckfarbe und b) Erhöhung des Anteils roter Schalenfarbe bei solchen Früchten oder auf der Seite der Frucht, die sonst schlecht gefärbt ist. Beide Forschungsansätze können zu den vom Konsumenten gewünschten rot gefärbten und gesünderen Früchten sowie der erwünschten höheren Einstufung und Bezahlung bei der Vermarktung der Früchte, nicht nur beim Apfel, führen. Häufig unbekannte oder unterschätzte Nebenwirkungen bekannter und neuer chemischer Produkte und physikalischer Verfahren werden anhand der grundlegenden Regelmechanismen der Farbbildung erklärt. Bei den auf Farbwirkung längerfristig untersuchten Blattdüngern zeigten die meisten Monophosphate im Durchschnitt der Jahre mäßige Effekte in Höhe von 3–5 % Farbverbesserung bzw. größeren Anteil Früchte mit besserer Schalenfarbe (> 50 %). Nur ‘Seniphos’ (Phosphat u. a. mit 4 % CaO) erhöhte den Anteil Deckfarbe regelmäßig um bis zu 8 %. Unter den weißen Partikelfilmen erschienen Kaolin und CaCO3 als Reflektor auf den Blättern und Früchten nördlich des 50. Breitengrades ungeeignet zur Verbesserung der Fruchtfarbe, während sie in sonnenstarken Gebieten erfolgreich gegen Sonnenbrand eingesetzt werden. Zu den unerwünschten Nebenwirkungen bei unsachgemäßer Anwendung, zu spätem Einsatzzeitpunkt und Überdosierung bei Benzyladenin (6-BA)-Präparaten zur Ausdünnung und ProhexadionCalcium u. a. zur Triebverkürzung gehören Verminderung der Rotfärbung bei Apfelfrüchten. Für den Einsatz von Methyl-Jasmonat, Aminoethoxyvinylglycin (AVG) und Abscisinsäure (ABA) zur Förderung der Fruchtausfärbung besteht zur Zeit (2014) in Europa keine Zulassung. Licht-Reflektoren wie Kunststoffgewebe- und Alufolien können bei einmaligem sowie Kalk, Kaolin, weiße Farbe, Titandioxid, Papier und Stroh als Mulch bei mehrmaligem Ausbringen in den Fahrgassen, am 50.°N mindestens 4 Wochen vor der erwarteten Ernte, die Fruchtausfärbung erheblich verbessern. Sie wirken, wie erwünscht, auf die schlecht belichteten Partien der Baumkrone unten und in der Mitte sowie auf die nach innen zum Baumstamm und nach unten gerichtete Seite der Apfelfrüchte. Mit einer Größenordnung von 8–10 % Farbverbesserung deckt dies, bei einmaligem Auslegen der Gewebe- oder Alufolien pro Jahr, die Materialkosten ab. Die Wirkung der Lichtreflektoren ist, wie erwünscht, in schwach färbenden Jahren stärker als in gut färbenden, und bei spät reifenden Sorten besser als bei früh reifenden, wobei auf die Belange des Landschaftsschutzes und aktuelle Zulassungssituation zu achten ist. Zuerst sollten alle Kultur- und Pflegemaßnahmen zur Verbesserung der Belichtung in der Baumkrone wie Winter-, Sommer- und Wurzelschnitt ausgeschöpft werden, um die Fruchtfarbe am 50.°N zu verbessern. Darüber hinaus steht heute eine breite Palette an Reflektoren, Monophosphaten bzw. Calciumphosphaten, chemischen Farbverbesserern sowie Verdunstungskühlung durch Beregnung an Abenden mit geringer Luftfeuchte, Wechsel zu einer helleren Hagelnetzfarbe, Ausweichen von Tal auf Hanglagen und Sortenwechsel zu roten Mutanten u. v. a. zur Verfügung. Stärker rot gefärbte Äpfel besitzen neben dem attraktiveren äußeren Erscheinungsbild durch ihren höheren Anteil sekundärer, bioaktiver Inhaltsstoffe einen nicht honorierten höheren Gesundheits- bzw- Mehrwert.

  • Do the Rootstocks Determine Tree Growth, Productivity and Fruit Quality of
           Pears, which Grow on Typical Heavy and Acidic Soil?
    • Abstract: Abstract During first 5 years after planting, we investigated the impact of quinces MA and BA.29 rootstocks on tree growth, precocity, yield, fruit quality and leaf nutrients content 60 days after full bloom (DAFB) of ‘Starking Delicious’, ‘Abbé Fetel’, and ‘Conference’ pear cultivars which are grown in the Cacak region on heavy and acidic soil. Results showed that rootstocks significantly influenced a small number of features which were evaluated. MA promoted better values of fruit weight and fruit length, whereas BA.29 increased leaf width and leaf area. Impact of rootstocks on tree growth and yield attributes were not found. A stronger effect than that of rootstock on all characteristics which were evaluated had the cultivar per se (genotype). Among cultivars, ‘Conference’ showed the highest values of leaf dimensions, leaf area and ripening index (RI); ‘Abbé Fetel’ had the highest flower numbers per umbels, cumulative yield, yield efficiency, all fruit physical characteristics, soluble solids content, titratable acidity, total sugar content and vitamin C content, while ‘Starking Delicious’ had the highest tree vigor, yield per tree and unit area.

  • Some Fruit Characteristics of Selected Cornelian Cherries ( Cornus mas L.)
           from Montenegro
    • Abstract: Abstract Some important fruit characteristics of twelve promising cornelian cherry selections from Montenegro were presented. Average fruit mass and flesh ratio of promising selections ranged from 1.90 g (BA-13) to 4.40 g (BR-135) and 83.16 % (BA-13) to 88.63 % (BR-135). External fruit color was dark red in the majority of selections but there were also selections with a red and yellow color. The selections had a total dry matter content between 18.83 % (BP-07) and 27.73 % (BP-54); total acid content between 1.65 % (BP-38) and 3.54 % (BP-07); total sugar content between 10.42 % (PL-99) and 17.52 % (BR-135), reducing sugar content between 8.73 % (BP-21) and 15.78 % (BR-135); sucrose content between 0.29 % (BP-38) and 3.51 % (BA-13); ash content between 0.65 % (BP-07) and 1.59 % (ŽB-143); Ca-pectate content between 1.03 % (BA-13) and 2.47 % (BP-51) and vitamin C content between 52 mg/100 g (BP-07) and 103 mg/100 g (ŽB-143). The results showed that a particularly high content of pectin and vitamin C of the selections make them suitable for table use and various forms of processing. The selection BR-135 was found to be the most promising overall for the best fruit mass and chemical composition characteristics, except its vitamin C content.

  • Micropropagation of Promising Jujube ( Ziziphus jujuba Mill.) Genotypes
    • Abstract: Abstract In the present study, two selected jujube genotypes (20-C-51 and 20-C-52) were used. The effects of different growth regulator combinations, carbon sources (sucrose, glucose and fructose) and silver nitrate concentrations on in vitro propagation of jujube were investigated. The highest percentage of explants that produced shoots (100 %) and the number of shoots per explant (5.5) were obtained on MS medium supplemented with 0.1 mg L−1 TDZ + 0.5 mg L−1 BAP + 0.1 mg L−1 IBA + 0.3 mg L−1 GA3. Different amounts of carbon sources and silver nitrate did not increase the percentage of explant that developed in to shoots and the number of shoots per explant. The highest rooting percentage (76.7 %) was obtained on MS and half-strength MS media supplemented with 2.0 mg L−1 IBA.

  • Exkursionsbericht: Süßkirschenproduktion in Australien
    • Abstract: Zusammenfassung Auf einer Fachexkursion in den Südosten und Süden Australiens machten sich Obstbauern im Dezember 2014 ein Bild von der australischen Süßkirschenproduktion. Der Anbau ist exportorientiert, was hohe Standards bei Sortierung, Verpackung und Haltbarkeit erfordert. Große Produktionseinheiten, niedrige Baumformen wie der Spanish Bush oder der Kym-Green-Bush sowie ein hoher Technisierungsgrad bei Sortierung und Verpackung helfen, die Kosten trotz hoher Stundenlöhne zu senken. Durch größere Nähe zu den Hauptabnehmern in Ostasien im Vergleich zum Mitbewerber Chile und die Nutzung der Luftfracht können Preise realisiert werden, die eine Produktion wirtschaftlich machen.

  • Apple Variety Assessment with Analytical Hierarchy Process
    • Abstract: Abstract Selection of a proper cultivar is one of the most important management decisions when investing into apple orchard. This paper presents a methodology for evaluation of suitability for cultivation of some apple cultivars by using a multi-criteria model based on analytical hierarchy process. The software tool Expert Choice was used to support growers in making decisions about which new apple cultivar to grow. The model was applied to 13 cultivars with data derived from questionnaires completed by group of experts of different fields (orchardists, experts for fruit production economics and fruit marketing, cultivar breeders, experts of state service and commission for introduction of new cultivars, experts for fruit storage and fruit quality assessment, plant protection and fruit growing advisers). The results are shown as priority for individual cultivar. The potential of the model for assessing apple cultivar is demonstrated with the aim of providing a comprehensive explanation and justification of the assessment technique. It also indicates strong and weak points (in market potential, fruit estimation, production demands and tree estimation) of each assessed cultivar.

  • Dimensional, Frictional, and Color Properties of Four Quince Cultivars (
           Cydonia oblonga Miller)
    • Abstract: Abstract Basic dimensional, frictional and color properties of four quince cultivars, namely ‘Kış Ayvası’, ‘Anzav Dere’, ‘Ekmek Ayvası’ and ‘Ecem’, were determined in this study. Physical features, namely length, width, geometric mean diameter, sphericity, aspect ratio, surface area, projected area, volume, mass, static coefficient of friction on aluminum, plywood and steel surfaces, and color features such as L*, a*, b*, hue angle, and chroma were determined and compared for the quince cultivars. The differences among the cultivars were statistically significant in terms of most properties investigated. The values of length, width, geometric mean diameter, sphericity, and fruit mass of four quince cultivars were established between 75.32–91.68 mm, 68.56–90.53 mm, 70.72–90.88 mm, 94.02–99.18 %, and 175.12–329.44 g., respectively. The highest static coefficient of friction (0.47) has observed for aluminum surface as the lowest static coefficient of friction (0.23) has observed for steel surface.

  • Einfluss der Unterlage auf Wuchs, Ertrag und Fruchtqualität von
           Süßkirschen ( Prunus avium L.) der Sorten ‘Regina’
           und ‘Kordia’ im Nachbau in Ostösterreich
    • Abstract: Zusammenfassung In einem siebenjährigen Feldversuch (2006–2012) in der Versuchsanlage der Universität für Bodenkultur in Wien wurde der Einfluss unterschiedlicher Unterlagen (‘Gisela 5’, ‘Gisela 6’, ‘PHL-C’, ‘Piku 1’, ‘Weiroot 158’) auf Wuchs- und Ertragsparameter der Süßkirschensorten ‘Regina’ und ‘Kordia’ untersucht, von 2010–2012 auch auf innere und äußere Fruchtparameter. Die Veredlungen auf ‘Gisela 6’ zeigten den stärksten Wuchs und Einzelbaumertrag von allen Unterlagen. ‘Weiroot 158’ und ‘PHL-C’ wuchsen stärker als ‘Gisela 5’ und ‘Piku 1’ und hatten ähnliche Einzelbaumerträge, demnach aber einen geringeren spezifischen Ertrag. ‘Gisela 5’ und ‘Piku 1’ wiesen den höchsten spezifischen Ertrag, ‘Piku 1’ allerdings zum Teil auch ein geringeres Einzelfruchtgewicht als die anderen Unterlagen auf. Bei der Fruchtqualität gab es keine gravierenden Unterschiede. Aufgrund dieser Ergebnisse kann ‘Gisela 5’ für diesen Standort auch für den Nachbau nach Kirschen als geeignete schwach bis mittelstark wachsende Unterlage eingestuft werden, und zwar günstiger als die im Wuchs vergleichbare Unterlage ‘Piku 1’. Auf noch trockeneren und schwach wüchsigen Standorten dürfte ‘Gisela 6’ besser geeignet sein als die bei uns im Vergleich zu ‘Gisela 5’ getesteten etwas stärker wachsenden Unterlagen ‘Weiroot 158’ und ‘PHL-C’.

  • Fruit Cracking in Mango ( Mangifera indica L.) cv. ‘Dashehari’
    • Abstract: Abstract The mango (Mangifera indica L.) is native to South and Southeast Asia, from where it has been distributed worldwide to become one of the most cultivated fruits in the tropics. It is the national fruit of India. In India, harvest and sale of mangoes take place during March-May and the fruits have high economic value in India. Studies were first time conducted on mango fruits to observe the severity of fruit cracking incidence. The stone was exposed in case of longitudinal type cracking and never exposed in star type cracking. The longitudinal cracking was 3.8, 3.4 and 1.7 % and star type cracking was 0.3, 1.8 and 0.02 % during 2009, 2010 and 2011, respectively. The lesser pulp thickness and higher stone weight in fruit cracked samples may have responsible for fruit cracking. There was a close relationship between fruit cracking and 3 months average weather conditions. The maximum temperature had positive relation with total fruit cracking.

  • Benzyladenine and Gibberellin Applications Improve Fruit Weight and Delay
           Maturity of Sweet Cherry
    • Abstract: Abstract Fruit size has special importance for small-fruited early maturing cherry cultivars. In this study the effects of pre-harvest benzyladenine (BA) and BA plus gibberellin (GA) applications on fruit size and quality of ‘Noir de Guben’ sweet cherry (Prunus avium) were evaluated. ‘Noir de Guben’ trees were sprayed to run off with BA (50, 100 and 150 ppm) and BA + GA4+7 (12.5, 25, and 50 ppm) at straw-yellow color stage of the fruit. Fruit treated with BA (50, 100 and 150 ppm) and BA + GA4+7 (25 and 50 ppm) were significantly heavier and larger than the control. BA and BA + GA4+7 applications did not affect fruit firmness and fruit pH. 50 ppm BA-treated fruit had higher SSC (Soluble Solid Content) than control fruit. Excluding 25 ppm BA treatments, all treated fruit had higher acidity than the control fruit. BA and BA + GA4+7 applications delayed skin color development of the treated fruit. ‘Noir de Guben’ trees treated with the optimum concentrations of BA (150 ppm) and BA + GA4+7 (50 ppm) yielded fruit with 16.84 and 10.6 % greater weight, respectively.

  • Apricot Vegetative Growth, Tree Mortality, Productivity, Fruit Quality and
           Leaf Nutrient Composition as Affected by Myrobalan Rootstock and
           Blackthorn Inter-Stem
    • Abstract: Abstract The behavior of five apricots grafted across Blackthorn inter-stem (BI) on Myrobalan stock and on Myrobalan rootstock (MR) was evaluated through vegetative growth, tree mortality, productivity, fruit quality and leaf nutrient composition from the 1st to the 6th leaf. The trial was performed in the Prislonica village (Cacak, Serbia), on a dry, shallow, sandy-loam and acidic soil. Results showed that MR improved tree vigor, yield per tree, cumulative yield, fruit weight, flesh rate, acidity, antioxidant power, leaf N, K, Ca and Mn contents and better balanced nutritional values for macronutrients. BI increased tree mortality, yield efficiency, yield per hectare, total phenolic and total flavonoid contents, and leaf P and Fe amounts. Wide variability among cultivars for evaluated traits was observed on both BI and MR. The more vigorous trees had ‘Biljana’ as compared with others on both BI and MR, whereas the most productive cultivar was ‘Vera’ on BI and ‘Biljana’ on MR. The highest and similar fruit weight had ‘Roxana’ and ‘Harcot’, whereas the highest stone weight and flesh rate was found in ‘Vera’ and ‘Harcot’, respectively, all in both BI and MR. Fruits harvested from ‘Aleksandar’ trees were rich in soluble solids content (SSC), titratable acidity (TA) and total flavonoid content (TFC), ‘Harcot’ in total phenolic content (TPC), and ‘Roxana’ in acidity and total antioxidant capacity (TAC), also on both BI and MR. The better balanced nutritional values were promoted by BI. Regarding cultivars, the best balanced nutritional values for macronutrients were exhibited by ‘Vera’ on BI, and by ‘Harcot’ on MR. For micronutrients, the wider imbalance among nutrients was found in ‘Roxana’ on BI, and in ‘Vera’ on MR.

  • 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.
