| To determine the overall degree of polymorphism, detect similarities among the accessions and collect highly valued genotypes of native apples, 21 characters of 18 autochthonous apple cultivars were studied for three years. Particular individual accessions were selected from the south region of Serbia according to economically valuable characters and tested in situ. Agronomic evaluation of germplasm accessions revealed considerable diversity among different accessions for all the characters studied. The analysis of variance revealed significant differences among the accessions and among years for some characters as well. Cluster analysis distinguished Malus sp. accessions into three distinct groups. Despite of the significant differences among the... |

| In Brazil, one of the top apple producing countries in the world, apple processing is an increasing activity, with pomace as the main by-product. To extract pectin from pomace, factors affecting process and product should be studied for optimization. A model to produce LMP directly from dried apple pomace was established observing the effects of HNO3 concentration and the time of reaction at 97ºC, analyzed from a statistical and practical point of view. The model for gravimetric yield (R² =0.9834) predicts the highest value of 20.07 g/100 g (126 mM; 14.07 min) of a pectin with a degree of esterification of 48.49%. The model for degree of esterification of extracted pectin (R²= 0.9797) predicts the lowest value of 43.73% (200 mM; 10.07 min) with a yield of... |

| The aim of the present study was to evaluate the growth and development of apple rootstock shoots submitted to different photon flux densities (7, 14, 21 and 60 µmol m-2 s-1) and three culture media. The best photon flux for maximizing growth, number of shoots and leaves was 14 µmol m-2 s-1, which also resulted in the highest values of chloroplastic pigments. On the other hand, the highest photon flux (60 µmol m-2 s-1) decreased significantly these parameters. Medium with reduced sucrose concentration did not affect the analyzed parameters, enabling an efficient multiplication of the cultivar with only 1% of sucrose. |

| The composition of apple base wine was found to be suitable for conversion into vermouth. The spices extract contained more TSS, tannins, esters, volatile acid but lower titrable acid than apple base wine. To optimize and develop apple vermouth with different ethanol concentrations (12%, 15%, 18%), sugar content (4%, 8%) and spices extract (2.5% and 5.0%) was prepared and was evaluated. Significant differences in physico-chemical characteristics and sensory quality amongst the vermouths having different levels of alcohol, sugar and spices extract were noted. Generally, increasing ethanol content decreased titrable acidity, tannins, macroelements and colour units while micro-elements, viscosity and total esters were increased. Increased sugar level affected... |

| Abstract The aim of this study was to develop a kefir apple-based vinegar and evaluate this fermentation process using new methodology with Biospeckle Laser. Brazilian kefir grains were inoculated in apple must for vinegar production. In this study, the microbial community present in kefir, and correspondent vinegar, was investigated using Matrix Assisted Laser Desorption/Ionization - Time of Flight Mass Spectrometry (MALDI-TOF MS) technique. Saccharomyces cerevisiae, Lactobacillus paracasei, Lactobacillus plantarum, Acetobacter pasteurianus and Acetobacter syzygii were the microbial species identified. S. cerevisiae, L. plantarum, A. pasteurianus and A. syzygii were found in smaller quantities at the beginning of the alcoholic fermentation, but were found... |

| Apple scab (Venturia inaequalis) is the most important disease in Chilean apple (Malus domestica Borkh.) orchards where fungicide management is the main tool to control disease. Sensitivity tests to difenoconazole, fenarimol, mancozeb, and pyrimethanil fungicides were conducted on V. inaequalis wild isolates to construct local baseline sensitivity distributions, and compare them with a collection of isolates from seven different commercial orchards with no evidence of practical resistance. In vitro assays were conducted and sensitivity was measured as inhibition of mycelial growth (difenoconazole, fenarimol, pyrimethanil) or conidial germination (mancozeb). Departure from the baseline distribution to less sensitivity was found for difenoconazole,... |

| The present study extracted pectin from Pink Lady apples (Malus pumila), which present at physiological maturity an average 50% of red-color coverage, to assess whether this variety is characterized by a high (HM) or low methoxyl value (LM). The raw materials were obtained from the Marengo farm, Los Niches, Curicó province, in the south-central region of Chile. Acid hydrolysis was used and the material was then subjected to sensory analysis, evaluating the organoleptic characteristics of pectin. The pectin was extracted with citric acid, which was tested under three pH conditions (2.5, 3.0 and 3.5, the latter corresponding to the natural pH of apples) for 60 and 90 min and subjected to a constant temperature of 90 °C. The degree of esterification (DE) of... |

| Recently, plant growth regulators have been used for various purposes in apples. Methyl jasmonate (MeJA) has significant effects on the physiology, postharvest biology, processing, and chemical composition of apples. In the present study, the effects of MeJAMeJa treatments on the physicochemical quality and bioactive compounds (total antioxidant activity, total phenolics, and total anthocyanins) of 'Fuji' apples were investigated. The following doses of MeJa were used: 0 (control); 1; 120; 2,240; and 4,480 mg L-1. The highest geometric mean diameter, fruit mass, flesh firmness and skin thickness were obtained from the 2,240 mg L-1 MeJA treatment. Fruits harvested from control trees exhibited the highest total soluble solids content (TSSC) and pH, whereas... |

| Codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), is the key pest of apple and walnut production worldwide. Among other variables, successful management of this pest is dependent on adult dispersal at the local scale. Body mass and wing geometric morphology were evaluated on female and male codling moth adults collected from apple and walnut trees in three localities of the Region of Maule. Codling moth adults were obtained by rearing diapausing larvae collected from the field. Newly emerged adults were killed, and the total dry weight, thorax weight and abdomen weight were calculated. The wings were cleared and mounted for morphometric analyses: 15 and 11 characteristics of the fore and hind wings, respectively, were measured, including the... |
