| The origin of Chanco cheese in Chile, between 1750 and 1860, is discussed. The inventories of eight cheese factories from the 18th and 19th centuries as well as additional documentary sources from the time period are studied. Chanco cheese was a cooked and matured cheese from cow and, mainly, sheep milk. The original productive zone was limited by the Maule and Itata rivers, in the Central Valley. In the 18th and 19th centuries, Chanco cheese was recognized as the best cheese in Chile; its production and marketing were well established during the first two thirds of the19th century, and it commanded good market prices based on its fame. Chanco cheese was eaten throughout almost the entire country, from Copiapó to Valdivia. Chanco cheese was also... |

| This trial aimed to evaluate the bioavailability of DL-2-hydroxy-4-(methyl) butanoic acid (DL-HMBA) and a poly-herbal ingredient (PHI) in relation to DL-methionine (DLM) on broilers. A sample of 1100 broiler chickens of the Cobb 500 strain, both male and female, were fed either a basal diet without industrial methionine supplementation or a basal diet that was supplemented with three DL-HMBA levels (0.170, 0.340, and 0.511%) or three DLM levels (0.111, 0.221, and 0.332%) in an amount equivalent to 65% of the respective DL-HMBA levels (on a product weight basis) and three levels of PHI (0.111, 0.221, and 0.332%) in amounts equivalent to the used DLM levels from 1 to 21 days of age. The simultaneous linear regression analysis (slope ratio) revealed a... |

Agr. 40(2): 351-360. Nothofagus dombeyi grows in a wide variety of sites in Chile (30-47°S), but there is little knowledge about its productive potential. This lack of information hinders decision-making to better guide the production of goods and services from these forests. This study was conducted in central-southern Chile (39°S-41°S), where this species is prominent, especially in secondary forests. The aim of the study was to determine the homogeneous edaphoclimatic zones for secondary forests of N. dombeyi based on the integration of environmental factors.... |

| En la primavera al otoño del año 2005, en el norte de Kanto, localizado en el centro de Japón se preparó un área de campo para cultivar tomate de ramillete (tomate cherry) (Lycopersicon esculentum var. cerasiforme) con tres tipos de cobertura: 1. Paja de arroz con salvado de arroz, 2. Paja de arroz solamente y 3. Cobertura con polietileno. La cosecha de los frutos se realizó desde junio hasta finales de septiembre. Hubo diferencias significativas entre los tratamientos, en el rendimiento total de los frutos (p = 0,0379) y el de frutos normales (p = 0,0458). Las mayores producciones de frutos totales (3,4 kgplanta-1 ) se obtuvieron con el tratamiento de paja de arroz con salvado de arroz, seguido por los otros dos tratamientos con alrededor de 2,5... |

| This study analyzed the physical characteristics, number of seeds per kilogram, seed weight, germination characteristics, germination percentage, germination energy, germination period and the germination vigor of sweet chestnut seeds from two forest plantations in the Los Ríos region of Chile. No significant differences were found in any of the characteristics related to the collection zone. Following the international classification systems for seeds of this species, the values of the physical characteristics allow us to classify these seeds as a small caliber or "chestnut". The values of the germination characteristics (>80%) demonstrate a good germination for chestnut seeds of forest origin. |

| In the last 10 years, interest in research on polyphenol-rich fruit species has increased due to the potential health benefits of these species, mainly attributed to their high anthocyanin content and antioxidant activity. Six polyphenol-rich fruit species (blueberries, raspberries, blackberries, strawberries, pomegranates and maqui berries) were harvested at the same maturity stage during the same growing season and were compared according to their total phenolic (Folin-Ciocalteu method) and total anthocyanin (pH differential method) contents and antioxidant activity using ferric-reducing antioxidant power (FRAP assay) and 2,2-diphenylpicrylhydrazyl (DPPH) radical scavenging capacity methods. With the results of this study, the polyphenolic status of the... |

Agr. 41(2): 263-271. The Robinson pipette method (Pipette) is accurate and precise but time consuming. Bouyoucos (1936) proposed a more rapid and simpler procedure called the hydrometer method. Both analytical techniques are sedimentation procedures accepted as standard techniques for particle-size analysis. The sand, silt, and clay contents of several soil samples were determined using the Pipette method as a control and compared with the Bouyoucus, the Bouyoucos Modified (Bouyoucos_M) and the Bouyoucos Modified with gravimetric determination of the sand content... |

Agr. 40(3): 629-636. The common bean is an important food in the human diet. Certain storage conditions, high temperatures and high humidity, cause a texture defect that reduces the acceptability of common beans. The present study aimed at evaluating the effect of storage on the physicochemical properties of common bean grains and the relationship between accelerated aging at 40 °C and 76% RH and storage under natural conditions. Two varieties of common beans (Iapar 81 - carioca variety and Iapar 44 - black variety) were stored at 40 °C and 76% RH for 15, 30, 45, 60... |

| The secretion of enzymes involved in biocontrol from the wild T. harzianum strains Th11 and Th12 and the mutants Th11A80.1, Th11C40.1 and Th12A10.1 was studied after their cultivation in the presence of R. solani cell walls as the sole carbon source. The results showed that endoprotease activity in the supernatants from Th11A80.1 and Th11C40.1 increased 2.77 and 4.79-fold, respectively, and the P-1,3-glucanase and P-1,4-chitinase activity from Th12A10.1 increased 1.86 and 1.54-fold, respectively, compared with the corresponding parental strains. The role of the three enzymes in the biocontrol of R. solani is discussed. |

| A set of 75 wine samples from seven of the major wine producing regions in Chile were analyzed with flame atomic absorption spectroscopy (AAS) to determine their content of major metallic elements (K, Mg, Ca, Na, Fe and Zn). The results obtained were further analyzed with principal component analysis (PCA) in an attempt to loosely discriminate these wines according to grape type and geographical origin. The metal concentrations measured were within normal ranges, according to previously published data from other wine producing countries. Multivariate statistics allowed the possibility to reasonably discriminate between red and white wines, and to show a distinctive pattern of Na concentration, with higher total contents for the wines produced in the... |

| The extraction of high-quality DNA is essential for studies conducted at the molecular level in species with an abundance of contaminants in their tissues, such as some landraces of potato and maize, in which it is difficult to extract good-quality genomic DNA. Compounds such as polyphenols interfere with the amplification of DNA during polymerase chain reaction (PCR), which makes it difficult to conduct PCR-based studies ofmolecular markers. This article describes a simple and robust protocol for DNA isolation that was applied to potato and maize landraces and resulted in a high DNA concentration with excellent purity and quality. This method is based on the method of Krizman et al. (2006) with some modifications and was tested on potato leaves and young... |

| Se analizó la variabilidad en el florecimiento de cinco poblaciones de Eucalyptus cladocalyx establecidos en la Región de Coquimbo. Se consideró al florecimiento como una respuesta binaria medida a los 30 meses de edad. Por lo tanto, se ajustó un modelo linear generalizado para analizar el efecto de procedencias. Posteriormente, se estudió la variabilidad genética dentro de la mejor procedencia, a través de inferencia Bayesiana, vía algoritmo de Gibbs. Inicialmente, se consideraron dos sitios, Hacienda Caracas y Tunga Norte, sector costero e interior de la Provincia de Choapa, respectivamente. En el sector costero, sólo un 1,33% de los árboles presentaron eventos de florecimiento, mientras que en Tunga Norte, este valor fue de 23,43%. Debido a este... |

Aging gene pathway of microRNAs 156/157 and 172 is altered in juvenile and adult plants from in vitro propagated Prunus sp. Cien. Inv. Agr. 43(3):429-441. In vitro culture is a very popular technique to mass propagate valuable plant genotypes, including Prunus sp. cultivars. Plants that undergo tissue culture processes often change their morphology and behavior due to the "rejuvenation" caused by the plant growth regulators included in the medium. To evaluate the effects of rejuvenation by tissue culture in Prunus sp., the expression patterns of the aging gene pathway described in plant models, which include the highly conserved microRNA (miRNA or miR) 156/157 and 172... |

| Las poblaciones de peces nativos están disminuyendo debido a varios factores que impactan en el ambiente. Como forma de abordar este problema, se han realizado varias acciones como por, ejemplo, el repoblamiento. Sin embargo, estas acciones se realizan sin ningún respaldo científico. Esto puede, además de no ser eficiente, provocar una pérdida de la diversidad genética en las poblaciones, pudiendo ocasionar impactos irreversibles en las próximas generaciones. Por esta razón, el empleo de marcadores moleculares, que permitan monitorear genéticamente las poblaciones parece fundamental para lograr la conservación de la ictiofauna |

| To evaluate increased levels of dehydrated olive cake (DOC) in lambs ration on main carcass traits, 40 Suffolk Down male lambs (75.8 ± 7.4 days of age, 24.5 ± 3.1 kg live weight) were randomly assigned to one of five treatment groups. Four experimental isoenergetic and isoproteic diets were used with different levels of DOC: 0, 16, 32 and 48%, and an un-weaned group were kept with their mothers on grazing. Lambs had 8 days of adaptation to the diets, which were gradually introduced along with good quality alfalfa hay. During 47 days of the experiment, the lambs were confined in individual pens (1.4 m²) and subsequently slaughtered at 123 ± 7 days with an average live weight of 32.56 ± 2.62 kg. The live weight at slaughter (LWS), hot carcass weight, cold... |

| The citrophilus mealybug, Pseudococcus calceolariae, is a polyphagous pest that has a major impact on fruit crops in central Chile, and is of quarantine importance for many markets. To study many control alternatives, it is important to develop efficient rearing protocols. The objective of this work was to determine mealybug development on three different plant substrates: sprouted potatoes, lemon fruits and Butternut squash. Insects were inoculated on the substrates, maintained at 25 °C and in total darkness until completing their development. Every one to 4 days, advancement on the development was checked by counting the exuvia. Mean developmental time for each stage, adult longevity, fecundity and fertility were determined. Preimaginal developmental... |
