The researches done at UASVM Cluj-Napoca in the frame of Horticultural product technology Department between 2014-2015 years followed the behavior of five apple cultivars at processing as clear juice. The apple juice characteristics (soluble solids content, organic acids content and clarification grade) were analyzed at processing of apples as clear juice and three months later, in order to determine how the initial characteristics of raw material were found again in the finished product. In order to provide the microbiological stability of juice, preservation was done with two chemical methods (sulfur dioxide – SO2 and sodium benzoate) and one physical method (pasteurization). The obtained results revealed ‘Florina’ cultivar, which had a processing efficiency as juice about 60%, high soluble solids content, 1% acidity, good clarification grade of juice, and pasteurization as microbiological stabilization method.

The objective of this study was to determine influence of different soil type on apple yield and quality. To investigate the variation in fruit quality, apples were harvested at commercial maturity on two different soil type. The investigations was conducted in experimental apple orchards located in Focsani region on two different soil type: luvic  brown typical and  luvic brown pseudogleizate. Fruits of Jonathan and Golden Delicios cultivars were tested for color, soluble solids content, total acidity, ascorbic acid, anthocyanins content and chlorophyls content with specific analytrical methods. At harvest yield, dry matter, soluble solids content, ascorbic acid and acidity were affected by soil type. In this study, no significant soil effect was found on color, anthocyanins and chlorophyll fruit content. The results obtained in this study suggest that luvic brown pseudogleizate soil leading to increased yields and enhanced fruit quality.

`Golden Delicious', `Delicious', and `Spartan' apples (Malus domestics Borkh.) showed a high, moderate, and low tolerance, respectively, to methyl bromide fumigation. Incidence of external and internal disorders increased, in most instances, with longer storage periods after fumigation treatments and with longer exposure times to the fumigant. Dips in diphenylamine before fumigation reduced, but did not prevent, disorders. Fumigation had little effect on firmness and no effect on soluble solids content or titratable acidity. Methyl bromide concentrations with a low risk of disorder development were 32 to 64 g·m-3 for `Golden Delicious', 32 to 48 g·m-3 for `Delicious', and 32 g·m-3 for `Spartan', all at 10C for 2 hours.

Development of prediction models for the quality of apples is useful in guiding fruit tree nutrition and in optimising fruit management. The interrelationships between the leaf nutrient contents and some fruit quality indices were studied in five apple cultivars &ndash; Generos, Florina, Delicios de Voinesti, Jonathan and Pionier. Highly significant relationships between N and Fe contents (R<sup>2</sup> = 0.734; P &lt; 0.01) and between Cu and K (R<sup>2</sup> = 0.702; P &lt; 0.01) were found. Acidity was negatively correlated with soluble solids content in the cvs Generos, Delicios de Voinesti and Jonathan, whereas the respective correlation in the apple cv. Pionier was positive. In cv. Florina fruits no significant correlation was found between acidity and soluble solids content. Among macroelements, nitrogen had a considerable contribution to fruit acidity and this allows to predict this index with a high degree of safety (R<sup>2</sup> = 0.690; RMSEP<sub>N</sub> = 0.105). Microelements have a lower contribution to acidity and a higher one to the sugar accumulation; in case of Zn are R<sup>2</sup> = 0.809; RMSEP<sub>Zn</sub> = 4.250. &nbsp;

Quality of Carrots Grown for Processing as Affected by Nitrogen Fertilization and Harvest TermIn 2007-2008 the effect of nitrogen fertilization and harvest term on quality of two carrot cultivars was investigated. The field experiment was carried out in Żelazna Experimental Station of Warsaw University of Life Sciences. Karotan F1and Trafford F1cultivars, commonly grown for juice industry, were the objects of the experiment. Carrot seeds were sown at the beginning of May. Nitrogen fertilization was applied in five rates, ranged from 0 to 120 kg·ha-1and in two terms — before sowing and in the middle of growing season. Roots were harvested in three terms: mid-September, mid-October and the first decade of November. After harvest there were determined: nitrates (NO3) content in carrot roots and juice, soluble solids, colour parameters of juice in CIE L*a*b*system. The dose and the term of nitrogen fertilization influenced nitrates content in carrots, and the highest NO3concentration was found in carrots fertilized with 120 kg·ha-1of N before sowing. Karotan showed higher nitrates accumulation than Trafford. The content of nitrates in the roots was markedly higher than in carrot juice. Nitrates content in carrots decreased with delaying of harvest time, in opposite to soluble solids content. Soluble solids content and colour parameters of carrot juice were not affected by nitrogen fertilization, but the lowest L*, a*and b*values were observed at the last term of harvest.

Grape Juices

The Campanha Gaucha region, southern Brazil, has received significant investments in Viticulture during the last decades, especially for the production of quality wines. However, implementing the production of American and hybrid grapes in this region constitutes and opportunity to supply the increasing demand of the grape juice market in Brazil. Juices of two varieties, “Bordô” and “Concord”, from two locations, Dom Pedrito and Santana do Livramento, were analysed in terms of the following physico-chemical aspects: total city, volatile acidity, density, pH, soluble solids content, color intensity, and hue. “Bordô” juices presented higher total acidity and did not differ in relation to location. Higher volatile acidity was found in “Concord” juice from Santana do Livramento. Higher pH was found in the variety “Concord” and in the location Dom Pedrito. For this same location, the “Concord” grape juices showed higher soluble solids values. Color intensity was higher in Santana do Livramento. Color hue was higher in Dom Pedrito. Both variety and location impacted significantly on physico-chemical aspects of grape juices, although all the grapes were produced within the Campanha Gaucha region.

Optical sensor data can be used to determine changes in anthocyanins, chlorophyll and soluble solids content (SSC) in apple production. In this study, visible and near-infrared spectra (729 to 975 nm) were transformed to SSC values by advanced multivariate calibration models i.e., partial least square regression (PLSR) in order to test the substitution of destructive chemical analyses through non-destructive optical measurements. Spectral field scans were carried out from 2016 to 2018 on marked ‘Braeburn’ apples in Southwest Germany. The study combines an in-depth statistical analyses of longitudinal SSC values with horticultural knowledge to set guidelines for further applied use of SSC predictions in the orchard to gain insights into apple carbohydrate physiology. The PLSR models were investigated with respect to sample size, seasonal variation, laboratory errors and the explanatory power of PLSR models when applied to independent samples. As a result of Monte Carlo simulations, PLSR modelled SSC only depended to a minor extent on the absolute number and accuracy of the wet chemistry laboratory calibration measurements. The comparison between non-destructive SSC determinations in the orchard with standard destructive lab testing at harvest on an independent sample showed mean differences of 0.5% SSC over all study years. SSC modelling with longitudinal linear mixed-effect models linked high crop loads to lower SSC values at harvest and higher SSC values for fruit from the top part of a tree.

Orchard performance is influenced by weed competition. In this study, the effects of weed competition on nutrient contents, chemical and physical fruit quality properties were sought. The study was carried out in a high-density apple orchard (‘Golden Delicious’/M.9) over two consecutive growing seasons. The effect of weed competition was studied at three different levels: weak, moderate and strong. Fruit firmness, soluble solids content, macronutrients (such as nitrogen, potassium and calcium) and potassium+magnesium/calcium ratio in fruit were significantly affected by weed competition. Strong weed competition negatively affected soluble solids content and potassium+magnesium/calcium ratio. In both trial years, soluble solids content was significantly higher in weak weed competition. In the first year of the study, soluble solids content ranged between 13.77±0.06% (strong weed competition) and 15.20±0.10% (weak weed competition). In the following year, soluble solids content values were determined as 13.13±0.23% in strong weed competition and 13.83±0.21% in weak weed competition. Weak weed competition showed superiority for fruit weight and potassium+magnesium/calcium ratio. As a whole, this study indicates that insufficient weed control in tree rows might be a limiting factor for fruit quality in high-density apple orchards.

Calcium chloride (CaCl2) and Ca(OH)2 sprays reduced rain splitting in Van cherries (Prunus avium L.). Multiple applications were better than single sprays. Soluble solids content was increased in many instances by the treatments. Fruit shrivel was appreciable in cherries sprayed with Ca(OH)2 particularly in hot seasons. Single or multiple applications of Nutri-Save (a polymeric coating), Pro-Stick (a sticking agent) and Envy (an antitranspirant) did not affect rain splitting in Stella cherries.
