Atlantic Area

The Mid-Atlantic area has a long, warm growing season and a reputation for grainy or firm, yellow apple products. There is interest in varieties that are large, firm, yellow-fleshed, that store and process well. The attributes of four NY selections, grown in PA, are described. NY 179 (Loop Red Rome X Yorking) fruit firmness (FF) dropped from 9 to 8.5 kg from 270 to 300 Julian days (JD). Over this same period, soluble solids (SS) rose from 13-15%. At 270 JD dropped fruit (DF) ranged from 0-5% while at 300 JD they ranged from 0-10%. Mean fruit weight was 285 g. NY 180 (Loop Red Rome X Yorking) averaged 351 g and FF was similar to NY 179. From 270 to 300 JD SS rose from 12-15%. Dropped fruit rose from 0-10% at 270 JD to 35% by 285 JD but to 95% by 300 JD. NY 88 (Melrose X Monroe) had a FF of 8.5 kg at 255 JD which decreased to about 7.5 kg at 300 JD. Over this same period SS rose from 13 -14.5%. At 255 JD DF were 0%; they ranged from 0-10% at 300 JD and never exceeded 10%. NY 151 (Red Spy X Yorking) averaged 171 g. At 270 JD FF was 12 kg falling to 11 kg at 330 JD. Over this period SS rose from 11-16%. Drops increased from 0% at 270 JD to 10-20% at 330 JD. These selections are undergoing regular and CA storage and processing tests.

ABSTRACTThe production of high quality fruits is a necessary factor for the adaptation and production of plant species with economic viability. Thus, an experiment was conducted from July 2012 to January 2013 to evaluate the fruit quality of the ‘Eva’ and ‘Princesa’ apple cultivars as a function of nitrogen fertilization in Petrolina, PE, Brazil. The experimental design consisted of randomized blocks, with treatments distributed in a factorial arrangement 2 x 4, corresponding to apple cultivars (Eva and Princesa) and nitrogen doses (40; 80; 120 and 160 kg of N ha-1), with four replications and three plants in each plot. The fruit characteristics, such as fruit mass, skin color (luminosity, chromaticity, and colour angle), size (width and length), pulp firmness, titratable acidity (TA), soluble solids (SS) and the SS/TA ratio, were recorded. Nitrogen doses do not affect fruit quality of studied apple cultivars. The fruit quality attributes are different between apple cultivars: fruit firmness, SS/TA ratio, fruit mass and fruit diameter are superior for Princesa cultivar, while the fruit length for Eva cultivar is superior.

The objective of this study was to compare the physico-chemical properties of 10 apple cultivars grown in mid hills of India. Fruit weight, volume, size, total soluble solids (T.S.S.), total sugars, titratable acidity and ascorbic acid content were measured in the cultivars Aurora, Brookfield, Braeburn, Galaxy, Azetec, Scarlet Gala, Marini Red, Jonagold, Royal Gala and Royal Delicious. The results showed significant differences in physico-chemical attributes of apple cultivars. Among all the cultivars the maximum fruit size (50.66 mm length, 74.73 mm diameter) and fruit weight (170.12 g) were observed in cv. Royal Delicious, while the minimum fruit size (40.52 mm length, 53.03 mm diameter) and weight (110.97 g) were measured in Azetec and Aurora, respectively. The highest volume (196.79 ml) of fruit was registered in Royal Delicious in comparison to the minimum (125.75 ml) in Aurora. The maximum T.S.S. (14.27 °B) and acidity (0.717%) was noticed in Scarlet Gala and Marini Red, respectively. While the minimum T.S.S. and acidity was observed in Marini Red (11.20 °B) and Azetec (0.186%). The ascorbic acid varied from 6.07 mg/100 g in Royal Gala to 9.86 mg/100 g in Braeburn, whereas the total sugar ranged 11.36% in Royal Gala to 7.06% in Jonagold.

Twenty-eight apple cultivars were selected for their potential for hard cider production in Ontario. An experiment was conducted to evaluate their horticultural potential in the province. After being planted in spring 2015, the trees were evaluated annually for their survival, tree height and spread, trunk growth, flowering dates, flower counts, fruit per tree, pre-harvest drop, crop load, fruit weight, fruit firmness, juicing extraction efficiency, and harvest dates. These horticultural attributes were sufficient to discriminate between cultivars. Additional exploratory analyses indicated a relationship between horticultural attributes and a cultivar’s origin, with British cider cultivars blooming the latest, American cider apples producing the most juice, and French cider cultivars having the highest pre-harvest fruit drop. Cultivars in this study that show promise for continued research in Ontario include Binet Rouge, Bramley’s Seedling, Breakwell, Bulmers Norman, Calville Blanc d’Hiver, Cline Russet, Cox Orange Pippin, Crimson Crisp®, Dabinett, Enterprise, Esopus Spitzenberg, Golden Russet, GoldRush, Medaille d’Or, Porter’s Perfection, and Stoke Red.

This experiment was conducted to determine the effects of deficit irrigation and growing season on fruit quality, carotenoid content and yield of red-, orange-, and yellow-fleshed diploid and triploid watermelon. Irrigation rates were 1.0 evapotranspiration (ET) and 0.5 ET. Diploid cultivars were Summer Flavor 710 (red), Tendersweet (orange), and Summer Gold (yellow). Triploid cultivars were Summer Sweet 5244 (red), Sunshine (orange), and Amarillo (yellow). Four-week old containerized transplants were planted in the field at TAES-Uvalde on 27 Mar. and 21 May 2003. Deficit irrigation imposed after plants were fully established reduced the individual fruit weight and size in the early planting. Soluble solids content (SSC) and firmness was not affected by irrigation rate in both plantings. SSC varied across cultivars and increased with maturity, particularly for the triploid cultivar Amarillo. In general, triploids were firmer than diploid cultivars. Total carotenoid content was not affected by irrigation during early planting. Diploid and triploid red-fleshed watermelon cultivars had significantly higher carotenoid content than orange- and yellow-fleshed cultivars. The major carotenoid was lycopene (more than 65%), followed by prolycopene (20%) and B-carotene (7%).

Many trials to supply germanium to fruit have been carried out since tests have confirmed germanium's role as a medical substance. Supplying germanium in orchards by soil and foliar application was not effective because of loss from rainfall. In order to increase germanium absorption by fruit, this study carried out tree trunk injections during the growing season. Two types of germanium, GeO (inorganic type) and Ge-132 (organic type), in concentrations of 5, 10, 25, and 50 mg·L–1 were supplied to `Niitaka' pear trees by trunk injection (1.5 L/tree), four times at 15-day intervals from June 2004. The treatment with 50 mg·L–1 GeO showed decreased fruit weight, but 50 mg·L–1 Ge-132 showed no difference to the control and other treatments. Fruit lenticels were increased in size by all of the Ge treatments in comparison to control fruit. Soluble solids as well as Hunter value `a' of the fruits of all Ge treatments were higher than that of the control. Flesh browning after peeling the fruit was delayed by the germanium treatment, and polyphenoloxidase (PPO) activities were lowered. Postharvest potentials were maintained at high levels for fruit firmness, physiological disorders, and decayed fruit during cold storage at 0 to 1 °C for 2 months.

Effects of three times and five rates of urea application on productivity, tree growth, soil nitrate movement, nutrient partitioning, and postharvest fruit quality of `Redspur Delicious' apple on M.7 rootstock over several years were studied. Time of application did not have significant effects on most fruit quality factors or yield. However, significant differences were observed for quality and yield measurements among different quantities of N. Fruit firmness decreased with every increment in N increase. Trees with N at 0.045 kg/tree had lower yield and higher fruit firmness than those with higher quantities of N. Fruit weight and color decreased with each increment increase in the quantity of N. Trees with N at 0.045 and 0.18 kg/tree had significantly better (more red) color and lower fruit N and leaf N than those with higher quantities of N. Bud tissue nutrients were affected by quantity of N application. Fruit from trees with N at <0.18 kg/tree had lower soluble solids. High N increased fruit ethylene and respiration. Nitrogen application affected 2-methyl butyl acetate of fruit. Monitoring nitrate movement through the soil showed that application of N at >0.45 kg/tree, particularly in fall resulted in excess levels of nitrate, increasing the possibility of underground water contamination. Applying N at ≤0.32 kg/tree did not result in excess soil nitrate at 1.52-m depth.

The apple fruit is the second most frequently consumed, after bananas and some quality characteristics like size, gloss, color, and aroma influenced directly the flesh consumption. In this study, the external (weight, size, skin colour) and internal (firmness, total soluble solids, acidity, pH) fruit quality attributes were measured experimentally before the storage, using well defined techniques. 'Corelita', 'Coreal', 'Corealor', 'Coredova', 'Corejuno', 'Coretard', 'Coreagat', 'Coreor' and 'Coreprim' cultivars were registered, in the last 15 years, by Practical Scientific Institute of Horticulture and Food Technologies Chișinău, Republic of Moldova, as scab resistant varieties. The orchard trial was established at the Research Institute for Fruit Growing Pitesti, Romania in the spring 2014 on MM106 rootstock, at the spacing of 3.5 x 2 m and fruit samples were analyzed in 2019, 2020 and 2021 seasons. All studied cultivars were harvested before 'Florina' cv., used as control. Fruit weight was quite variable among genotypes, between 115.15 g at 'Coreal' cv. and 212.41 g at 'Corejuno', and most of the cultivars had smaller fruits than 'Florina' cv. Firmness and total soluble solids varied from 70.5 to 82.61 N and 12.77 to 16.77%Brix. The Hunter color values L, a, b, were found to be in the range of 46.12 to 56.76, - 6.46 to 14, 13.75 to 23.72, respectively. The data about the external and internal fruit quality of new Moldavian scab resistant apple cultivars are useful for growers, in order to introduce in the new orchards only cultivars with high quality fruits.

In order to study pollination and fruit set and determine the best pollinizers for two Iranian apple cultivars, Golab Kohanz and Shafiabadi, experiments were conducted during two years. Different pollen sources including pollen of cultivars Golab Isfahan, Golab Kohanz, Mashhad Nouri, Shafiabadi and also open pollination were used. Pollen sources had significant effects on fruit set, fruit weight, diameter, shape, dry weight, total soluble solids (TSS), sugar and seed contents in cv. Golab Kohanz. Trees pollinated by pollen of Shafiabadi had highest fruit set, fruit weight, diameter, shape, dry weight, TSS., sugar, and seed content. Pollen sources significantly affected fruit set, fruit weight, diameter, shape, and seed content in cv. Shafiabadi. The highest fruit set, fruit weight, diameter, and seed content was resulted from flowers pollinated by Golab Kohanz. Golab Kohanz and Shafiabadi had 3.3% and 0.5% fruit set from self pollination, respectively, and seemed to be completely incompatible. Fruit resulted from self pollination were generally small and of low quality. Regardless to fruits obtained from pollination, different pollen sources had small effects on fruit quality. The results indicated that cvs. Shafiabadi and Mashad Nouri are the best pollinizers for Golab Kohanz and Golab Kohanz was superior pollinizers for Shafiabadi.

Cultivar and planting site are two factors that often receive minimal attention, but can have a significant impact on the quality of apple (Malus ×domestica) produced. A regional project, NE-183 The Multidisciplinary Evaluation of New Apple Cultivars, was initiated in 1995 to systematically evaluate 20 newer apple cultivars on Malling.9 (M.9) rootstock across 19 sites in North America. This paper describes the effect of cultivar and site on fruit quality and sensory attributes at a number of the planting sites for the 1998 through 2000 growing seasons. Fruit quality attributes measured included fruit weight, length: diameter ratio, soluble solids concentration (SSC), titratable acidity (TA), flesh firmness, red overcolor, and russet. Fruit sensory characteristics rated included crispness, sweetness, and juiciness, based on a unipolar intensity scale (where 1 = least and 5 = most), and acidity, flavor, attractiveness, and desirability based on a bipolar hedonic scale (where 1 = dislike and 5 = like extremely). All fruit quality and sensory variables measured were affected by cultivar. The two-way interaction of cultivar and planting site was significant for all response variables except SSC, TA, russet, crispness, and sweetness ratings. The SSC: TA ratio was strongly correlated with sweetness and acidity sensory rating, but was weakly correlated with flavor rating. The results demonstrate that no one cultivar is ideally suited for all planting sites and no planting site is ideal for maximizing the quality of all apple cultivars.

The influence of bloom chemical thinner Wilthin on three apple cultivars (Royal Gala, Blushing Gold, and Ultra Gold) was investigated. Two experiments were conducted in 1995 and 1996 to determine the effect of Wilthin at 0%, 0.5%, 1.0%, and 1.5% on fruit length, fruit diameter, fruit weight, yield, juice pH, acidity, SSC, sucrose, glucose, fructose, fruit firmness, and fruit set. Wilthin reduced fruit set of `Royal Gala', `Ultra Gold', and `Blushing Golden' and increased yield of all cultivars. In general, Wilthin increased fruit weight of `Royal Gala', `Ultra Gold', and `Blushing Golden' both years. Wilthin increased fruit length and diameter of `Royal Gala' and `Ultra Gold', but it did not affect fruit length of `Blushing Golden'. Wilthin increased fruit juice pH of `Royal Gala', `Ultra Gold', and `Blushing Golden' during both years. Wilthin decreased fruit juice acidity of `Royal Gala', `Ultra Gold', and `Blushing Golden'. In 1995, Wilthin increased SSC of `Royal Gala' and `Ultra Gold'. In 1996, Wilthin did not effect SSC of `Royal Gala' and `Blushing Golden', but increased SSC of `Ultra Gold'. Wilthin increased sucrose concentration of `Royal Gala', `Ultra Gold', and `Blushing Golden'. Wilthin did not effect fruit juice glucose concentration of `Royal Gala' but increased fruit juice glucose concentration of `Ultra Gold' and `Blushing Golden'. Wilthin did not influenced fructose content of `Royal Gala' and `Blushing Golden' apples. Wilthin increased fructose contents of `Ultra Gold'. Accel increased fruit firmness of `Royal Gala', `Ultra Gold', and `Blushing Golden' and increased fruit firmness of `Royal Gala'.
