| Se evaluaron polvos vegetales de Chenopodium ambrosioides L., Chenopodium album L. y Chenopodium quinoa Willd. para el control de Sitophilus zeamais Motschulsky, bajo condiciones de laboratorio. Los parámetros evaluados fueron mortalidad y emergencia de insectos adultos, pérdida de peso y germinación de los granos, efecto ovicida y larvicida, fumigación, repelencia y residualidad de los polvos. El diseño experimental fue completamente al azar, con un arreglo factorial y tres repeticiones. La mayor mortalidad de insectos se obtuvo con los polvos de la inflorescencia y la mezcla de hojas y tallos de Chenopodium ambrosioides L., al 2% (p/p) con valores de 69,4% y 67,9% respectivamente. La menor emergencia de adultos se obtuvo con los mismos tratamientos. La... |

| Este trabalho foi realizado com o objetivo de avaliar o desenvolvimento e a produtividade de Quinoa variedade BRS-Piabiru semeada em diferentes datas dentro do período safrinha, em Campo Mourão, PR. Foram avaliadas seis datas de semeadura, a saber: 18/03/08, 02/04/08, 17/04/08, 02/05/08, 17/05/08 e 10/06/08. Os índices da cultura avaliados foram número de dias para a floração; número de dias para a maturação; altura das plantas na maturação e produtividade. O experimento foi realizado no delineamento experimental em blocos completos com os tratamentos ao acaso e em quatro repetições. Os resultados indicam que a data de semeadura teve influência no número de dias para a floração; número de dias para a maturação; altura das plantas na maturação e... |

| A experimentação pioneira com Chenopodium quinoa Willd tem demonstrado sua adaptabilidade à produção de grãos no cerrado. Seus frutos, do tipo aquênio, são cilíndricos, achatados e germinam rapidamente na presença de umidade, após a maturação fisiológica. Na fase inicial do seu desenvolvimento, a quinoa pode ser confundida com a planta daninha Chenopodium album, conhecida no Brasil como ançarinha-branca. As diferenças básicas entre as duas espécies se tornam mais visíveis após o florescimento: ramificação profusa, com rácemos axilares e terminais em C. album, em contraste com C. quinoa, na qual as panículas são terminais, à semelhança do sorgo; o pericarpo é claro e contrasta com o preto em C. album. A quinoa BRS Piabiru, primeiro cultivar para o Brasil,... |

| Se describen los efectos de la UV-B sobre la síntesis de pigmentos fotosintéticos (clorofila total, clorofila a, clorofila b, carotenoides), protectores (compuestos absorbentes de UV-B) y azúcares solubles (glucosa, fructosa y sacarosa) en cinco variedades de quinoa de diferentes orígenes geográficos. En general, se demuestra que las variedades reaccionan desplegando diferentes estrategias para protegerse de la radiación UV-B. Estas estrategias pueden ser de tipo morfológico, fisiológico y/o bioquímico. Una respuesta común, observada en las cinco variedades fue el incremento en el contenido de compuestos absorbentes de UV-B, lo que puede interpretarse como un "escudo químico" de protección para el aparato fotosintético frente al exceso de energía... |

| La semilla de quinoa (Chenopodium quinoa Willd) se caracteriza por presentar una composición balanceada; es rica en proteínas, fibra, vitaminas, minerales y antioxidantes, por lo que puede ser incorporada en la formulación de barras de cereal a fin de incrementar el valor nutricional de la alimentación diaria. El objetivo de este trabajo fue estudiar el efecto de la incorporación de semillas de quinoa en la calidad tecnológica, nutricional y sensorial de barras de cereal. Se elaboraron y analizaron tres muestras de barras de cereal, con diferentes porcentajes de sustitución de arroz crocante por semillas de quinoa y un control (sin quinoa). Se observó un incremento de peso de las barras de cereal, a medida que se aumentó el nivel de sustitución y una... |

| The present study was focused on the analysis of agronomical, nutritional, physicochemical, and antioxidant properties of six genetically different quinoa (Chenopodium quinoa Willd) genotypes cultivated in three distinctive geographical zones of Chile. Ancovinto and Cancosa genotypes from the northern Altiplano (19 ºS), Cáhuil and Faro from the central region (34 ºS), and Regalona and Villarica from the southern region (39 ºS) are representative of high genetic differentiation among the pooled samples, in particular between Altiplano and the central-southern groups. A Common-Garden Assay at 30 ºS showed significant differences among seed origins in all morphometric parameters and also in yields. Altiplano genotypes had larger panicule length but no seed... |

| Two field experiments were conducted during two successive seasons (2014/2015 and 2015/2016) at the Experimental Station of National Research Centre, Nubaria district, Beheira Governorate, Egypt, to study the effect of foliar treatment of quinoa plants with trehalose (Tre) (100µM and 500µM) on growth, photosynthetic pigments, seed yield quantity & quality, in fever of nutritional and antioxidant compounds in the yielded quinoa seeds which subjected to water deficiency (skipping two irrigation times at 50 & 60 days after sowing). Water deficiency caused marked decreases in quinoa plant growth parameters (shoot height, fresh and dry weights of shoot/plant) and photosynthetic pigments with marked increases in root growth parameters (root length, fresh... |

| Drying kinetics of quinoa-supplemented feed for laboratory rats during processing at 50, 60, 70, 80 and 90ºC was studied and modeled in this work. Desorption isotherm was obtained at 60ºC giving a monolayer moisture content of 0.04 g water/g d.m. The experimental drying curves showed that drying process took place only in the falling rate period. Several thin-layer drying equations available in the literature were evaluated based on determination coefficient (r²), sum squared errors (SSE) and Chi-square (χ2) statisticals. In comparison to the experimental moisture values, the values estimated with the Logarithmic model gave the best fit quality (r² >0.994, SSE < 0.00015 and χ2 < 0.00018), showing this equation could predict very accurately the... |

| This study explored the diversity of the quinoa crop in Chile from a nutritional perspective. Nutritional properties, minerals, vitamins, and saponin content were assessed in seeds of six Chilean quinoa (Chenopodium quinoa Willd.) ecotypes grown in three main production areas with distinctive climatic and edaphic conditions: Ancovinto and Cancosa in the North-Altiplano or High Plateau, Cáhuil and Faro in the central coastal area, and Regalona and Villarrica in the south of the country. There were significant differences (P < 0.05) in all the nutritional properties of the quinoa seeds in all three areas. Quinoa of the Villarrica ecotype showed the highest protein content (16.10 g 100 g-1 DM) and the highest content of vitamins E and C (4.644 ± 0.240 and... |

| Abstract The study aimed to assess the influence of quinoa flour of different particle size and degree of wheat flour replacement on dough and bread characteristics. Dynamic rheology and farinographs were used to describe the dough parameters. Specific volume, texture, porosity, color, overall quality and chemical assessment were performed as well. It could be observed that the degree of wheat flour substitution by quinoa flour significantly influenced the G’ and G” values in linear and quadratic terms (p ≤ 0.01 and p ≤ 0.05). Particle size played a significant role in increasing G’ and G” only in quadratic terms. Increasing quinoa substitution of wheat flour and interaction of PS and QS significantly increased the porosity of breadcrumbs. Moisture content... |

| Insects are attracted to plants by visual and olfactory cues. The quinoa moth, Eurysacca melanocampta Meyrick (Lepidoptera: Gelechiidae), is the main insect pest of the quinoa crop, Chenopodium quinoa Willd. (Chenopodiales: Chenopodiaceae), in the southern Peruvian Andes, causing grain yield losses. The aim of this study was to investigate the behavioural response of adult quinoa moths to olfactory stimuli. Specifically, the objectives of this study were: 1) to determine the capacity of E. melanocampta adults of searching for quinoa plants using plant olfactory cues; 2) to determine the preference of E. melanocampta females for the odours derived from two varieties of quinoa: Amarilla de Marangani and Blanca de Junín; and 3) to assess the attraction of... |
