This work was conducted in the Centro de Pesquisa, Pós-graduação e Preservação Amazônica (CIPCA), located in the Ecuadorian Amazon Region, with the goal to analyze the presence of weeds in promising clones of cocoa. The EET-95, EET-96 and EET-103 promising clones were evaluated, and the control sample was CCN-51. To do so, the relative frequency and distribution of the existing weeds were determined, as well as their biomass, which was statistically analyzed by the ANOVA of a factor and the HSD Tukey’s test. The presence of weeds was influenced by the studied genotypes, due to the fact that promising clones were associated to high frequency and distribution, such as Cyperus odoratus, Megathyrsus maximus, Sauvagesia erecta ssp. erecta. Other species appeared to be associated more to the CCN-51 clone, such as Scleria pterota, Paspalum conjugatuns and Rottboellia cochinchinensis. Higher weed biomass was verified in clone CCN-51.
This is a new hybrid fusion strategy based primarily on the implementation of two former and differentiated approaches to multimodal fusion [11] in multimodal dialogue systems. Both approaches, their predecessors and their respective advantages and disadvantages will be described in order to illustrate how the new strategy merges them into a more solid and coherent solution. The first strategy was largely based on Johnston´s approach [5] and implies the inclusion of multimodal grammar entries and temporal constraints. The second approach implied the fusion of information coming from different channels at dialogue level. The new hybrid strategy hereby described requires the inclusion of multimodal grammar entries and temporal constraints plus the additional information at dialogue level utilized in the second strategy. Within this new approach therefore, the fusion process will be initiated at grammar level and will be culminated at dialogue level.
En el presente trabajo se analizó la variabilidad morfológica del cultivo del cacao existente en la Provincia de Pastaza, en lugares que fueron previamente definidos, donde se seleccionaron plantas con un comportamiento notable en cuanto a producción y resistencia a enfermedades. Fueron valorados 48 individuos, dentro de los cuales se incluyeron tres testigos que fueron los clones CCN-51, ICS-95 y Nacional, caracterizados por su alta producción y calidad industrial, así como resistencia a moniliasis. Se evaluaron 32 variables, tanto cualitativas como cuantitativas del fruto, semillas, hojas y flores con el objetivo de caracterizar los individuos, lo que fue analizado estadísticamente mediante análisis multivariado. Las características de las flores fueron los descriptores que permitieron separar individuos con mayor exactitud, los que se agruparon hacia los clones utilizados como testigos, así como por sectores, lo que demostró regionalización de los materiales analizados respondiendo el sector Triunfo hacia el cacao Nacional, Canelos hacia el ICS95 y el sector Arajuno que no mostró afinidad con los clones testigos. Se seleccionaron 25 árboles destacados.
