II Taller de hortalizas productividad - mercadeo 2003.

“…En Colombia y en general en el trópico la horticultura se ha desarrollado siguiendo patrones de países temperados, con lo que a pesar de que muchas de las especies utilizadas son de origen tropical, su domesticación y prácticas de manejo se estructuraron en el subtropico en latitudes más altas. Lo anterior ha significado la generación de un costoso "paquete" de componentes para el manejo del ambiente (manejo y adaptación) de tal forma que las plantas puedan adaptarse sin problemas a las diversas condiciones de cultivo lo que ha significa- '11) >7 do aumentos permanentes en costos de producción, por el uso de "acondicionadores o adaptadores " de los cultivos tales como fertilizantes, funguicidas, herbicidas, etc., etc. …”

“…Species of major food crops display centers of diversity, as previously proposed, while the rest of edible plants follow latitudinal distribution patterns similarly to the total plant diversity, with higher species richness at lower latitudes. The International Union for Conservation of Nature Red List includes global conservation assessments for at least 30% of edible plants, with ca. 86% of them conserved ex situ. …”

Thermal buffering capacity of the germination phenotype across the environmental envelope of the Cactaceae por Seal, Charlotte E., Daws, Matthew I., Flores, Joel, Ortega Baes, Francisco Pablo, Galindez, Guadalupe, León Lobos, Pedro, Sandoval, Ana, Ceroni Stuva, Aldo, Ramírez Bullón, Natali, Dávila Aranda, Patricia, Ordoñez Salanueva, Cesar A., Yáñez Espinosa, Laura, Ulian, Tiziana, Amosso, Cecilia, Zubani, Lino, Torres Bilbao, Alberto, Pritchard, Hugh W.

“…We selected 55 cactus species from the Americas, all geo‐referenced seed collections, reflecting the broad environmental envelope of the family across 70° of latitude and 3700 m of altitude. We then generated empirical data of the thermal germination response from which we estimated the minimum (Tb), optimum (To) and ceiling (Tc) temperature for germination and the thermal time (θ50) for each species based on the linearity of germination rate with temperature. …”

Temperate Subantarctic Forests: A Huge Natural Laboratory por Marchelli, Paula, Pastorino, Mario Juan, Gallo, Leonardo Ariel

“…In addition, abundant neotropical elements characteristics of the “Yungas” in NE Argentina (e.g., Azara, Chusquea, Crinodendron, Drimys, Escallonia among others) reflect a history of recurrent connections with ecosystems of lower latitudes (Arroyo et al. 1995).…”

Water Deficit Modulates the Relationship between Temperature and Unsaturated Fatty Acid Profile in Soybean Seed Oil por Carrera, Constanza Soledad, Dardanelli, Julio Luis

“…The UFA profile was determined in harvested seeds of commercial cultivars grown in 76 environments in Argentina (29–38° S latitude). To our knowledge, this is the first study demonstrating a differential response of oleic (Ol), linoleic (Li), and linolenic (Ln) acids and Ol/(Li + Ln) ratio to temperature during seed fill (TmR5R7) under different conditions of field water availability. …”
