| En los sistemas agrícolas, el suministro adecuado de nutrientes a cada especie vegetal que lo componen, es uno de los factores que define su productividad. Con el objetivo de evaluar el efecto del nitrógeno (N), fósforo (P) y potasio (K) en el crecimiento vegetativo, rendimiento y calidad de fruto del manzano ʽAgua Nueva’/M106/manzano criollo de Huejotzingo, Puebla, bajo el sistema de cultivos intercalados, se estudiaron cinco niveles de cada uno. El experimento de milpa (maíz y frijol) intercalada con árboles de manzano, inició en el año 2002 en el Campo Experimental Valle de México (CEVAMEX) del INIFAP. El presente trabajo incluyó solamente los años 2010 y 2011. Dosis intermedias de N y P y baja de K (100-40-64 g de N, P2O5 y K2O por árbol por año)... |

| The generation of transgenic apple plants relies on the molecular analysis of transgene integration and expression based on polymerase chain reaction (PCR) analysis, blotting techniques and enzymatic assays on vitro leaves of putative transgenic regenerates. In order to assess the uniformity and the stability of transfer DNA (T-DNA) integration and gene expression, we studied 26 transgenic apple lines carrying the attacin E gene from Hyalophora cecropia, the β-glucuronidase gene, and the nptII gene. Plants were evaluated using standard molecular techniques, such as PCR, Southern blot, reverse transcription PCR (RT-PCR) and Enzyme Linked Immunosorbent Assay (ELISA), and propagated in vitro on non-selective antibiotic-free media for four years to... |

| Diplodia species are known as pathogens on many woody hosts, including fruit trees, worldwide. In this study a collection of Diplodia isolates obtained mostly from apple and other Rosaceae hosts were identified based on morphological characters and DNA sequence data from ITS and EF1-α loci. The results show that the diversity of species associated with twig and branch cankers and fruit rot of apples is larger than previously recognised. Four species were identified, namely D. seriata and D. malorum (which is here reinstated for isolates with D. mutila-like conidia). Diplodia intermedia sp. nov. is closely related to D. seriata, and D. bulgarica sp. nov. is morphologically and phylogenetically distinct from all Diplodia species reported from apples. |

| the goal of this article was to determine the importance of apple attributes using two research techniques – self-explicated procedure and conjoint analysis. Research was conducted on a sample of 426 consumers of apples in Zagreb, Croatia. The results of self-explicated and conjoint analysis procedures revealed differences in ranking of apple attributes regarding their importance. It is demonstrated that conjoint analysis gives more detailed results and that it is not influenced by respondents’ tendency to give socially acceptable answers. The results of conjoint analysis also give more information for the producers of apples who can use them to create a product that matches consumers’ wishes. |

| Typically, marketers define market segments by their demographic characteristics, assuming that these segments represent consumers with relatively homogeneous buying patterns. A more managerially useful definition, however, groups consumers of similar behavior directly and then seeks to find demographic commonalities among them. This study uses a latent class analysis technique to segment consumers based on their responsiveness to a set of marketing variables, finding that a multiple-segment model provides a better fit to the data, and that these segments differ significantly in their responsiveness. By targeting marketing activities to their most responsive segments, the efficiency of commodity promotion can be dramatically improved. |

| Abstract To isolate protoplast, a pre-treatment was completed with the order to reduce and identify the phenolic contents round the year to encourage the isolation of protoplasts. Protoplasts from in vivo mesophyll leaves of apple cultivar “Anna” was isolated from 15 days old leaves by plasmolying in medium containing 90 g L-1 mannitol for half hour, then 130 g L-1 mannitol for half hour. Then using enzymatic mixture involving (1.5% cellulase + 0.5% pectianase + 1.5% Macrozyme) Prior to isolation. Anyhow, diverse factors, for example, Osmotic pressure, incubation period, sieve pore size, centrifugation period and hormonal balance was estimated using the techniques for isolation. The quantity of cells was computed as the quantity of cells per square on... |

| Harmonia axyridis was detected for the first time in Brazil in 2002. Since then, it has been recorded from the South to the Midwest of the country. Until now, almost all the registered cases were associated with the presence of aphids, its preferred source of food. Due to the occurrence of this species in areas of fruit growing in the South and Southeast of Brazil, the aim of this study was to analyze the preference and use of three different cultivars of fruit. The tests were set at 25ºC ± 1ºC, RH 70% ± 10%, and in a photophase of 12 h and with apples (Gala and Fuji), grapes (Niágara and Rubi), and pears (Williams and Asian). In the undamaged fruit experiment, the insects did not cause any noticeable damage. In the damaged and undamaged fruit experiment,... |

| Patulin is a mycotoxin produced by several fungal species of the genera Penicillium and Aspergillus, found on several fruit species and, remarkably, in apples and apple products. Patulin has a broad spectrum of toxicity, including carcinogenicity and teratogenicity in animals. Due to the stability of the molecule, considerable amounts of patulin still remain in apple products after processing. This paper reviews different analytical methods for patulin determination and methods to reduce levels of patulin in apple products as well. |

| Pear (Pyrus communis), which is intensively cultivated in subtropical and temperate climates, has recently attained the 3rd position in the world fruit ranking, just after apple and peach. This fruit exhibits certain similarities to apple with respect to the pulp, but pear is used as a raw material only when apple is no longer available, which suggests that the same technology line may be utilized. Both fruits do have processing compatibilities, and it is permissible to add pear juice to apple juice at levels defined by law. Quality indicators, such as pH, total acidity, total phenolic compounds and antioxidant activity were used. The simple sugar analysis clearly defines fructose as the main component in pear juice, and lower figures were found when... |
