The aim of this research was to study the effects of application of ‘hydrocomplex’ (H) and ‘Norway nitrate’ (NN) fertilizers on leaf and fruit nutrient concentrations and some fruit quality parameters in the following apple (Malus domestica Borkh) cultivars (cvs.): Golden Delicious and Black Ben Davis. Applications of 50 kg NN, 75 kg NN, 50 kg NN plus 50 kg H and 75 kg NN plus 25 kg H per 0.1 hectare significantly increased leaf Ca concentration of the cv. Golden Delicious in comparison with the control in the July 15 sampling period. Boron concentration of leaves of the cv. Black Ben Davis increased steadily throughout the season. Applications of 75 kg H and 75 kg H plus 25 kg NN per 0.1 hectare significantly increased fruit B concentration of the cv. Black Ben Davis at harvest. The ratios N/Ca, K/Ca and K + Mg/Ca in fruit were calculated for all treatments. Applications of 25–75 kg NN, 25–75 kg H as well as the combination of the two fertilizers decreased the ratios N/Ca, K/Ca and K + Mg/Ca of fruits of the cvs. Golden Delicious and Black Ben Davis in comparison with the control at harvest. Applications of 50 kg (ΝΝ), 75 kg (Η), 25 kg (ΝΝ) plus 75 kg (H) and 75 kg (NN) plus 25 kg (H) per 0.1 hectare significantly increased soluble solids of fruits of the cv. Golden Delicious at harvest.

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.

Apple (Malus domestica Borkh.), a popular and widely cultivated fruit world-wide, contains bioactive compounds responsible for their health benefits. Here we report the amounts of some bioactive compounds: two major triterpenes (oleanolic and ursolic acids) and polyphenols (phenolic acids, flavan-3-ols, flavonoids and t-resveratrol), together with bioactive properties of twelve apple cultivars measured by chromatographic and spectrophotometric methods. Significant variations were found comparing the bioactive potential of the investigated cultivars. High contents of phenolic acids were identified in the Montuan, Golden Delicious and Cretesc cultivars, while the most flavonoid dominant was the Richard cultivar. Starkrimson, Jonatan, Beliy Naliv and Richard cultivars present higher antioxidant capacity. Oleanolic acid ranged from 11 to 83 mg/g apple extract, while ursolic acid ranged from 55 to 436 mg/g apple extract, with higher amounts in Richard and Montuan cultivars. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) allowed the discrimination of apple cultivars depending on polyphenolic and triterpene acids composition. Caffeic acid, gallic acid and epicatechin were identified as the main bioactive compounds in Starkrimson, Jonathan, Beliy Naliv and Richard cultivars, while ursolic and oleanolic acids were identified in high amounts in Richard, Montuan, Golden Delicious, Idared and Beliy Naliv apple cultivars. The results obtained in this study will contribute to the understanding of the bioactive composition of apples as well as the importance of their capitalization to obtain value-added products that promote human health.

In this study, crop yield and fruit quality parameters (soluble solid concentration, sugar, total acid, and vitamin C content) of 15 apple cultivars including old, resistant and currently grown cultivars. The highest fruit yield among all 15 cultivars was obtained on CV. Jonagold with 15.5 kg/tree, while the lowest yield was measured on the resistant cultivar Reanda with 8.1 kg/tree. There were no significant differences among the cultivars in fruit diameter ranging from 70 mm in the case of cv. Húsvéti rozmaring to 82 mm for cv. Mutsu. Values of soluble solids concentration of the cultivars varied between 15.5% for cv. Téli Banán and 19.2% for cv. Renora. Sugar content values showed a similar tendency to soluble solids content. The highest and lowest total sugar content was observed on cvs. Jonagold and Renora and cv. Re­tina with 17% and 12.4%, respectively. Total acid content values ranged between 0.18% and 0.53% for cvs. Jonagold and Remo, respectively. Values of vitamin C content for the 15 apple cultivars varied between 2 mg% and 4 mg% for cv. Retina and cv. Mutsu, respectively.

Similar Tendency

The authors studied the effect of rootstocks with different growing vigour on fruit quality of different cultivars. Research results shows that best fruit diamter and fruit weight of all cultivars are for M9 rootstock. Similar tendency was found in skin colour, but in the case of Granny Smith, MM106 rootstock is more favourable because the green skin colour is necessary for the consumers’ acceptance. Seedling rootstok has some unfavourable effects on fruit quality, thus its usage is not expedient.

Compost Application

Ökológiai termesztésű almaültetvényben eltérő komposztadagok (0, 10, 25 és 50 kg N·ha−1) hatását vizsgáltuk a talaj tápelemtartalmának változására (0–30 és 30–60 cm-es mélységben). Mértük az egyes almafajták (Golden Delicious és Pinova) levelének szárazanyag- és Ca-tartalmát, továbbá vizsgáltuk e paraméterek alakulásának egymáshoz való viszonyát.A szabadföldi kísérletet a Debreceni Egyetem Kertészettudományi Intézetének Pallagi Kísérleti Telepén, a talaj- és növényminták analízisét az Agrokémiai és Talajtani Intézet laboratóriumaiban végeztük.A 2011. és 2012. évi eredményeket összevetve lényeges csökkenés mutatkozott a talaj AL-oldható P-tartalmában. Az évek múlásával jelentősen nőtt azonban a talajban a nitrát-, ammónia-, szerves-N és CaCl2-Mg tartalom a kijuttatott komposztadagok hatására. Az AL-K, -Ca, -Mg, a CaCl2-P, -K mennyisége és a pH közel azonosnak mondható.Az első kísérleti évben (2010-ben) még nem volt hatása a komposztnak. 2011-ben már észleltünk hatást, de a fagykár miatt nem volt termés a fákon. 2012-ben a nagy termésterhelés mellett is növekedést tapasztaltunk a szárazanyag-tartalom alakulásában mind a Golden Delicious, mind a Pinova fajták esetében. Adott kezeléseken belül az eltérő termésmennyiségekkel, továbbá az évjárattal összefüggő tendenciákat fedeztünk fel. A rendkívül csapadékos évben (2010) alacsony, míg az aszályos évben (2012) nagy szárazanyag-tartalom értékeket mértünk a levélben. A Golden Delicious és a Pinova esetében kapott tendencia fajtától, kezelés- és termesztés-technológiától függetlenül hasonló.A komposzt hatására 2010-ben a Golden Delicious leveleiben kismértékű, a Pinova leveleiben szignifikáns Ca-tartalombeli növekedést mértünk. Az évjárat hatásáról elmondható, hogy csapadékos évben a szakirodalmi adatoknál magasabb, míg száraz, terméshiányos évben alacsonyabb Ca-tartalommal számolhattunk. Bár a Ca-szintek alakulása tendenciájában megegyezett a két almafajta esetében, mégis megállapítható, hogy a Pinova leveleinek elemtartalma nagyobb volt, mint a Golden Delicious fáké.A levelek szárazanyag-tartalma és Ca-tartalma között fordított arányosságot bizonyítottunk.

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.

Crab Apple

The effect of row direction (N-S, E-W), plant density (conventional and intensive) and rootstock (M9, MM106 and crab apple) on the sensitivity of 41 apple cultivars to sunburn injury was studied at 6 locations (Derecske, Kálmánáaza, Nagykutas, Nagylapos, Siófok, Tornyospálca). During the observations the cultivars had rootstock-specific properties in respect of sunburn-susceptibility. Accordingly, the injury was decreased in the order: M9, MM106 and seedling rootstocks. The differences in sensitivity depend on the canopy of trees, caused finally by the growing vigour of rootstocks. Accordingly, the highest value of sunburn injury was observed on M9 rootstock, because this rootstock has a dwarfing effect upon the scion cultivars. Thus, vegetative area of these trees grow very slowly and the foliage is not enough compact to protect the fruit from solar radiation. The size and density of the foliage increased in the order: M9, MM 106 and crab apple seedling as rootstock. Moreover, relationships were demonstrated between the diameter of upper part of the crown, the leaf area, the number of fruits per tree and the injury of sunburn. Authors categorized the cultivars in respect of values of sunburn incidence: 1. „Not sensitive", II. „Moderately sensitive" and HI. „Strongly sensitive" categories were constituted. Generally, Topaz and Gala cultivars showed low damage (or were free from symptoms), in contrast to this, Golden mutants suffered relatively much. The most sensitive cultivar was Jonica on all the three rootstocks. We searched for relationship between the fruit quality parameters and the frequency of sunburn. Significant correlation was found in the cases of fruit size and the extent of cover-colour. The latter is interpreted with the fact that the best coloured fruits are found on the periphery of crown as a consequence of more intense irradiation.
