... the data presented in Table 4 it can be observed that, in the apple varieties studied during the experiment, there are positive and statistically proved tight bonds between certain morphologic characteristics of the fruits: the height is correlated to the index of shape, the weight and the volume of the fruits, the fruit diameter is correlated to the weight and the volume of the fruits, the weight is correlated to the fruit volume (in the last case, even if not in all cultivars, the sense of the difference significances for the respective characters was the same -e.g. ´Sir PrizeándPrizeánd´Jonathan´, Table 1). On the other hand, the fruit resistance to injury is not statistically correlated with any of the morphologic characters of the fruits. ...

... Physicochemical characteristics are shown in Table 1. Several studies have demonstrated that variations in the fruit weight, size and shape were mostly influenced by the genotype, soil, climatic conditions, and the fruit maturity stage [6,[67][68][69]. The total acid (TA) content and total soluble solids (TSS) are important factors for fruit quality, while the ratio TSS:TA is usually used for determination of the taste and palatability of the fruit and, therefore, the consumer acceptability [69]. ...
Feijoa (Acca sellowiana (O. Berg) Burret syn Feijoa sellowiana Berg) is a monotypic species belonging to the Myrtaceae family. Feijoa is cultivated in different countries, and it is mainly consumed as fresh fruit, due to its attractive nutritional quality, nevertheless, several feijoa-based products have been produced and are available in some niche and local markets. The fruits are not the only edible part of the tree since petals of hermaphrodite showy flowers can also be eaten. Fruits are rich in vitamin C, fiber, potassium, iodine, phosphorus, sugars, and calcium. In addition, a large number of bioactive compounds, with many health-promoting benefits, have been identified. This review is carried out with the aim to provide comprehensive and updated over-view of the state of the art related to the knowledge on feijoa, evaluating the main agronomic, qualitative, and nutraceutical traits of its edible parts. Moreover, the variability in feijoa genetic resources to identify and select promising genotypes useful for breeding programs and the postharvest management of fruit and edible flowers will be discussed. Overall, feijoa has great potential to be considered as a sustainable fruit crop from farm to table.
... It is worth mentioning that the larger fruit of 'Jonagold' had the smallest value for firmness (64.2 N/cm 2 ). Among the studied cultivars, small values (equivalent to a softer pulp) were scored also for 'Granny Smith' and 'Idared', although these are recon as having a firm pulp (Sestras et al., 2006 C et al./ Not Sci Biol, 2015, 7(1):140-149 Tasting panel evaluation (Sensory evaluation) The data obtained by the tastel panel evaluation forms, regarding the commercial aspect of apples and pulp traits, are given in Table 2 (data corresponding to Questionnaire 1) and Table 3 (data corresponding to Questionnaire 2). ...
... The fruit weight varied greatly among cultivars, from a minimum of 51.8 ± 4.10 g (Smith) to a maximum of 104.8 ± 7.77 g (Mammoth), although some statistically significant similarities between Apollo and Edenvale Supreme, Coolidge and Mammoth, David and Nazemetz and between Edenvale Late, Gemini and Roundjon were observed (Table 1). Several studies, on different fruit species, demonstrated that variations in the fruit weight were mainly influenced by the genotype but also by the soil, the climatic conditions and by the fruit maturity stage (Sestras et al., 2006;Gonç alves et al., 2006;Usenik et al., 2008;Serrano et al., 2009;Usenik et al., 2010). In our study the observed weight variability of the fruit of feijoa may be due to genetic differences among cultivars, since the pedoclimatic conditions are the same for all the tested cultivars. ...

The objective of this study was to analyse fruit quality through consumers’ perceptions and their preferences revealed by two panel questionnaires. Among the most common apple cultivars on the Romanian markets, were chosen the ones existing simultaneously and continuously (over two-years, during January-March): ‘Golden Delicious’, ‘Braeburn’, ‘Granny Smith’, ‘Red Delicious’, ‘Jonagold’, ‘Jonathan’, ‘Florina’, ‘Idared’. The consumers’ panel for sensory evaluation was represented by students, who completed two types of
questionnaires. Both questionnaires refer to foremost traits for dessert apple, such as fruit appearance size, shape, color) and intrinsic peculiarities (pulp consistency, juiciness, taste, flavor). First questionnaire comprised different scales for the traits (1-3, 1-5 or 1-15), while the second one consisted of the hedonic scale (1-9) for all traits. For commercial appearance of the fruits were highlighted ‘Idared’, ‘Granny Smith’, ‘Braeburn’ and especially ‘Jonagold’. ‘Braeburn’ was distinct by the highest quality taste (average grade 13.9 on the scoring taste scale 1-15) and also for fruit flavor. ‘Granny Smith’, a commercially attractive-looking fruit, received only an average of 6.2 for taste and 2.6 for flavor. ‘Granny Smith’ presented the largest value for the coefficients of variation for taste, this variety being preferred less by female than male tasters. Inconsistency of the market, prices and foreign assortment on Romanian market was illustrated by the lack of statistical correlations between commercial aspect of fruit and price. The study could provide useful background information for apples breeders, farmers and marketing fruits strategy. The use of different scales for panel evaluation, dependent on the relevance of traits, might be a proper solution for reducing bias. In this case, the 1-15 large scale for apple taste compared with lower ones for other traits assured a more appropriate image of the tasters’ preferences.

... The problem is further complicated by the fact that several different cultivars are grown in Pakistan which may vary considerably in their time of maturity and storage performance (Drake et al., 2002). While the genetic characteristics of the apple fruits for storage may vary, yet optimal storage may retain good organoleptic quality longer than suboptimum storage conditions (Sestras et al., 2006). Therefore, the present research was carried out to identify the optimum harvest stage in apple cultivars for maximum fruit quality and storage life and minimize post harvest losses in apple. ...
The experiment was conducted to study the effect of storage on quality parameters of apple cultivars harvested at different stages of maturity at Horticulture Postharvest Laboratory, KP Agricultural University, Peshawar-Pakistan during 2007-08. The fruits were harvested at three different stages of maturity at fifteen days interval representing early, mid and late harvesting stage from apple cultivars: Royal Gala, Mondial Gala, Golden Delicious and Red Delicious and evaluated for different quality parameters at 0 and 150 days storage at 5±10 °C with 60-70 % relative humidity. Cultivar Red Delicious had the highest ascorbic acid (12.49 mg/100g), firmness (5.85 kg/cm 2) but also the bitter pit (14.22 %) and soft rot (15.52 %) incidence, while titratable acidity (0.56 %) was observed in cultivar Mondial Gala. The percent weight loss, total soluble solids, total sugar, bitter pit incidence and soft rot increased while, juice content, titratable acidity, ascorbic acid and firmness declined with increase in storage duration. The juice content (47.68 %), total soluble solids (10.07), total sugar (9.31 %), ascorbic acid (10.11 mg/100g) and soft rot (9.52 %) recorded with early mature fruit, increased to juice content (59.33 %), total soluble solids (12.92), total sugar (12.98 %), ascorbic acid (12.50 %) and soft rot (15.22 %) accordingly in late mature fruits, while weight loss (3.34 %), titratable acidity (0.59 %), firmness (5.88 kg/cm 2), and bitter pit (11.69 %) recorded at early maturity stage, declined with delaying the harvesting to weight loss (1.93 %), starch score (3.21), titratable acidity (0.49 %), firmness (4.81 kg/cm 2), density of fruit (4.81 g/cm 3) and bitter pit (6.63 %) at late maturity stage.
... This method requires a minimum of handling and labour. After cooling is completed, the facility can be used for short-term storage as well (Sanz, 2005). Because cooling occurs over a period of several days or even longer, the electrical energy demand from the refrigeration system is relatively low. ...
The study presents a comparison of the loss that the fruit suffer during the storage period in both traditional and refrigerating storage, at the Fruit Research Station Cluj-Napoca, Romania. There were gathered biochemical data for four winter maturation apple varieties: Jonathan, Golden Delicious, Starkrimson and Wagener Premiat, during the months of October (at storage), December and March. The determined biochemical aspects were water, total sugar, and ascorbic acid. The refrigerating storage was better in comparison with the traditional storage, confirmed by biochemical composition. The lowest dehydration was for the apples stored in the refrigerating room. By storage method and apples varieties comparison, the lowest water loss was shown by Wagener Premiat varieties and the highest by Jonathan in refrigerating storage in comparison with traditional storage. Wagener Premiat varieties showed the best qualities even for total sugar and ascorbic acid in comparison with the others apples varieties studied. To keep the apples in optimum conditions, the genetic characters of each cultivar and the cultivar behaviour to CA storage is required.
... Tab. 5 Phenotypic (P) and genotypic (G) correlation among studied characteristics of the apple fruit As in the previous study (Sestras et al., 2006), there were positive and statistically correlations between certain morphologic characteristics of the fruits: the height was correlated to the diameter and volume of the fruits, and the fruit diameter to the volume of the fruits. In this case, depending on fruits position on the crown, the fruit's weight was not correlated to the fruit volume. ...
Apple fruits content in sugar differ depending on many factors as environmental conditions, technology, climate, cultivars etc. The objective of this study was to determine the sugar content and morphological traits of fruit of different apples cultivars, with summer ('Mollie's Delicious', 'Jersey Mac', 'Nebuta'), autumn ('Frumos de Voinesti', 'Prima', 'Priam', 'Pionier', 'Ardelean') and winter ('Golden Delicious', 'Feleac', 'Rosu de Cluj', 'Red Delicious') ripening, under the influence of area of crown where the fruits has formed. The highest sugar content was registered in the fruits belonging to 'Red Delicious' cultivars (17.8 °Bx in the bottom of the crown) and to 'Golden Delicious'(17.2 °Bx in the top of the crown), while the lowest sugar content was registered in fruits harvested from middle position of the 'Prima' trees crown (11.3 °Bx). The genotype determines evident differences for values of sugar apples content: 'Red Delicious' and 'Golden Delicious' were registered with highest value (16.4 and 16.2 °Bx), followed by 'Nebuta' (15.3 °Bx) and 'Rosu de Cluj' (15.2 °Bx). Regardless of cultivars, the fruits position in the crown influenced significantly their sugar content. The lowest content of sugar was registered for the fruits formed in the middle third of the crown (13.9 °Bx), while the lower third of the crown determined rich sugar content in the fruits (15.0 °Bx). There were identified both phenotypic and genotypic negative correlations between the sugar content and weight of the fruits. The results help apple breeders and fruit growers to know which apples are richest in sugar content and which technology of culture, pruning etc. should be applied if they want to obtain fruits with high or low sugar content.
