| Mycorrhizal associations in Smallanthus sonchifolius (Poepp. & Endl.) H. Robinson (Asteraceae), Yacon, an ancient Andean crop and Smallanthus macroscyphus (Baker ex Martius) A. Grau, wild yacon, a close wild relative are described for the frst time. Yacon fbrous roots growing under feld conditions have high levels of colonization by arbuscular mycorrhizal fungi (86 %). Other fungi colonizing roots included dark septate endophytes (45 %) and unidentifed fungi that are probably saprophytic (25 %) were observed. Only 9% of the samples analyzed were not colonized by any type of fungi. Glomus, Acaulospora, Scutellospora, Gigaspora and Pacispora were the main genera of arbuscular mycorrhiza identifed. A similar high degree of mycorrhizal colonization was... |

| The increasing interest in the commercial exploitation of yacon has demanded adequate technological knowledge for the implantation and management of the crop, including planting periods and cultivation regions that contribute to the satisfactory growth and development of the species. This study was conducted in two different locations, one in a mountainous region and another in a lowland region. In each location, yacon was planted in four different seasons, fall (April), winter (July), spring (September) and summer (December). We collected primary dry matter accumulation data for different parts of the plant and the leaf area at 30 day intervals. We used these values to calculate the following morphophysiological indexes: specific leaf area, leaf area... |

| This work was aimed at studying the influence of PFJ and/or sodium disulphite on Yacon pulp colour, and evaluating the sensory attributes of Yacon non-sugar pastes. A colour kinetic evaluation of browning in 11 treatments containing Yacon tubers, yellow passion fruit juice (PFJ) and/or sodium disulphite, over the course of 240 minutes was studied to inactivate the PPOs activity. The evaluation of the colour alterations of Yacon tuber by the addition of variable amounts of PFJ and sodium disulphite enabled identification of efficient treatments for the inhibition of browning: T7 (300 g kg -1 PFJ), T8 (400 g kg -1 PFJ), and T10 (150 g kg -1 PFJ + 0.25 g kg -1 sodium disulphite). These treatments presented high colour intensity (C*) and an insignificant (P... |

| ABSTRACT: The consumption of yacon has been increasing around the world due to the nutritional and pharmaceutical properties of this plant. The growing commercial interest in yacon (Smallanthus sonchifolius) generates a demand for crop management research studies, including the effect of weed competition on yacon, which was not yet studied. Thus, this study was performed with the objective of evaluating the effects of weed competition on yacon development and growth. The experimental design was completely randomized with four treatments and seven replicates. Treatments were yacon with the interference of four weed species: Cyperus rotundus L. (nutgrass), Commelina benghalensis L. (tropical spiderwort), Amaranthus viridis L. (slender amaranth) and Bidens... |

| Smallanthus sonchifolius (Poepp. & Endl.) H. Robinson (Asteraceae), conhecida como yacon, é uma espécie herbácea de clima tropical de altitude, tendo sido introduzida em diversos países, incluindo o Brasil, devido ao seu potencial alimentício, forrageiro e, principalmente, como substrato para a produção de inulina. Embora aspectos agronômicos e bioquímicos desta planta sejam relativamente conhecidos, pouco se sabe a respeito da morfologia e natureza do sistema subterrâneo, principal fonte de inulina. Verificou-se que o sistema subterrâneo tem natureza mista, sendo constituído por rizóforos e raízes delgadas e tuberosas, ambas adventícias. Canais secretores de substâncias lipídicas estão presentes nos rizóforos e raízes; nestas, os canais... |

| ABSTRACT In Brazil, studies on commercial exploitation of yacon are still scarce. A growing interest in this vegetable has demanded some researches on this crop cultivation management, though. Considering that yacon has a long cycle, which exposes the soil, studies on mulch management will be of great value. We used a randomized complete block design, with five replicates, under different soil mulches for yacon cultivation: two plastic film covers (black and double-sided), four mulches (corn husk, coffee husk in three levels), and the control (bare soil). Plastic mulch can be used for yacon cultivation, considering that the double sided plastic provides greater production of total roots; however, the same yield of the most valued roots was obtained using... |

| Abstract Yacon is a tuberous root from the Andean region being increasingly grown across the world due to the low caloric values of their roots and the functional properties of extractions of its leaves. However, there is still a gap in the knowledge of how the plant develops, and if physical and chemical changes are noticed regarding maturity. The subject of this work was to investigate the dynamics of a group of parameters and to establish correlations across them. To achieve this goal, leaves collected from three different parts of the plant in three months were assessed regarding size (plant height and leaf area), color and the presence of sesquiterpene lactones. Different methods of extraction were also studied and the total phenolic content was... |

| O yacon é uma raiz tuberosa que se destaca pelos seus compostos bioativos, como oligossacarídeos prebióticos (fruto-oligossacarídeos, FOS) e componentes fenólicos, especialmente o ácido clorogênico. As bebidas prebióticas são uma forma conveniente e versátil para o consumo de componentes funcionais, sendo a sua forma clarificada "com uso de membranas" um interessante mercado em expansão. Este trabalho descreve um processo para obtenção de suco clarificado de yacon e sua caracterização química e físico-química, com foco nos componentes funcionais (FOS e ácido clorogênico). Também foi analisada a aplicabilidade desse suco na forma de uma bebida mista com suco clarificado de caju. |

| ABSTRACT Yacon (Smallanthus sonchifolius) is a tuberous root from the Andean region in the South America rich em water, fructooligosaccharides and phenolic compounds, some of which are natural antioxidants and may help prevent the deleterious action of free radicals in the body. The yacon has attracted much attention due to their potential health benefits to humans. In this study the levels of total phenolics, tannins, phenolic acids, and total antioxidant activity were measured in the peel and pulp of yacon tubers both in the fresh and flour forms. The flours of yacon presented higher concentrations of total phenolics and tannins, especially peel flour. The yacon pulp flour stood out as the main source of phenolic acids, mainly caffeic and chlorogenic... |

| ABSTRACT Yacon is a crop which requires development of strategies for its cultivation. One of the possibilities is to introduce yacon in perennial crops using intercropping system. The aim of this study was to evaluate different planting densities of yacon grown in intercropping with corn under banana orchard, verifying its development and production. At 90 days after planting, morphological and physiological evaluations were done, at 210 days yacon was harvested, and its productivity calculated using the fresh tuberous root production. The Area Equivalence Index (IEA), and the Relative Contribution of Crops (CRC) to IEA were calculated. Yacon development and production were hampered by the corn intercropping (under the banana orchard), regardless of the... |
