ABSTRACT
The characteristic evolution of El Niño Southern Oscillation (ENSO) on timescales of months to years means that risks to agriculture have structure between seasons and years. The potential for consecutive ENSO-induced yield anomalies is of particular interest in major food producing areas, where modest changes in yield have significant effects on global markets. In this study, we analyse how multi-year El Niño and La Niña life cycles relate to climate sensitive portions of major crop-growing seasons in North and South America.
We analyse the dynamics underlying these life cycles to illustrate which aspects of the system are most important for agriculture. In North America, the same-season teleconnections affecting soybean and maize have been well studied, but we demonstrate the importance of lagged soil moisture teleconnections for wheat in the southern Great Plains. In South America, peak ENSO sea surface temperature (SST) teleconnections are concurrent with, and therefore critical for, wheat and maize growing seasons while soil moisture memory in Argentina plays an important role during the soybean growing season.
Finally, we show that ENSO teleconnection life cycles are consistent with historical yield anomalies. Both El Niño and La Niña life cycles tend to force consecutive seasons of either above or below expected yields. While the magnitude of the yield anomalies forced by ENSO is often modest, they occur in major crop-producing regions.

ABSTRACT.- Purple-fleshed sweet potatoes (PFSP) are a new product for Uruguayan consumers. It shows differentiable sensory char-acteristics and added nutritional benefits, but sensory and hedonic expectations raised by PFSP have not been explored yet in Uruguay. The aim of this work was to explore Uruguayan consumers' perception of PFSP with a special focus on the hedonic, sensory and emotional expectations raised by them in comparison to traditional yellow and orange-flesh genotypes available in the market. A series of pictures of three types of SP were used in a social-network-driven study completed by 179 SPconsumers. A word-association task and rating of expected liking together with exploring how they would feel after consumption using a check-all-that-apply (CATA) question composed of 21 emoji were carried out. Par-ticipants were also asked to describe the expected sensory characteristics using a CATA questions composed of 17 terms, selected based on results from previous sensory studies. Results revealed a lack of consumer familiarity with purple flesh coloration and lower expected liking scores compared to traditional orange and yellow flesh genotypes. It was also asso-ciated with scarce positive hedonic and emotional associations related to the emojisflushed face, face screaming in fear, grimacing face and weary face. Moreover, they were expected to have similar characteristics to yellow-fleshed sweet potatoes (YFSP) in terms of texture and flavor, being also associated with off-flavors presence. This highlights the need to develop diverse marketing strategies to increase familiarity before the commercial release of PFSP.

RESUMEN.- Los boniatos de pulpa violeta (BPV) constituyen un producto novedoso para los consumidores uruguayos. Presentan características fácilmente diferenciables, así como un valor nutricional añadido, pero aún se desconocen las expectativas sensoriales y hedónicas que generan en Uruguay. El objetivo de este trabajo fue explorar la percepción de los BPV con un foco especial en las expectativas hedónicas, sensoriales y emocionales en comparación con los tipos tradicionales presentes en el mercado. El estudio fue realizado con179 consumidores que respondieron preguntas online, presentándoles una serie de fotografías. Se realizó una asociación libre y la evaluación de aceptabilidad esperada, y se exploró cómo se sentirían luego de probarlos, utilizando un ?marque todo lo que corresponda? (CATA) compuesto de 21 emojis. También se solicitó a los participantes que describieran sus expectativas sensoriales aplicando un CATA compuesto por 17 términos validados en ensayos previos. Los resultados muestran una falta de familiaridad con la coloración violeta en la pulpa, lo que se refleja en menores valores de aceptabilidad esperada en comparación con los genotipos tradicionales de pulpa crema y naranja. Se asoció también con escasas asociaciones hedónicas positivas y emojis como cara de asombro o miedo, muecas o fatiga. Generaron expectativas sensoriales similares a los boniatos de pulpa crema en términos de textura y sabor, asociándose, además, con sabores no deseados. Esto resalta la necesidad de desarrollar estrategias de marketing para favorecer la familiaridad previo a la liberación comercial de los BPV.
