| description | Different aspects related to deterioration, treatments to extend cassava root durability, and root storage practices are briefly reviewed. The initiation and subsequent level of deterioration of cassava roots is closely related to the presence of mechanical damage which is normally caused at harvest. A subjective methos that allows the percentage of deterioration to be assessed is described. The results obtained show that var. MCo1 22 is more susceptible than MCo1 113. Changes in the color of cassava are due to occlusion of the xylem vessel fascicles and to the production of fluorescent compounds in the parenchyma among which scopoletin was identified. The percentage of deterioration in roots of var. MCo1 22 varied from less than 20 percent up to 90 percent, indicating that this var. could be susceptible or resistant depending on the conditions at harvest and that it is difficult to determine the absolute degree of susceptibility of a var. Evaluations of postharvest deterioration in 5 localities in Colombia, under different edaphoclimatic conditions, showed that there is a wide range of deterioration among the var. at CIAT-Palmira and in Popayan, while in the northern coast of Colombia the level of deterioration was considerably lower. All of the var. were resistant in Carimagua. Var. MCo1 1807 and MCo1 22 were also found to be the var. most susceptible to deterioration before canopy pruning and the most resistant after pruning.

(CIAT) Se revisan brevemente los diferentes aspectos relacionados con la deterioracion, los tratamientos para extender la durabilidad de las raices de yuca y las practicas de almacenamiento de las mismas. El inicio y el grado posterior de deterioracion de las raices esta estrechamente relacionado con la presencia de danos mecanicos, los cuales son normalmente ocasionados en el momento de la cosecha. Se describe un metodo subjetivo que permite evaluar el por ciento de deterioracion. Los resultados obtenidos muestran que la var. MCol 22 es mas susceptible que MCol 113. Los cambios de coloracion en la yuca son debidos a oclusiones de los haces xilogenos y a la produccion de compuestos fluorescentes en el parenquima entre los cuales se logro identificar la escopoletina. Se observo que el porcentaje de deterioracion de las raices de la var. MCol 22 varia desde menos del 20 por ciento hasta el 90 por ciento , lo cual demuestra que esta var. podria ser susceptible o resistente segun las condiciones de cosecha y que es dificil expresar el grado de susceptibilidad absoluta de una var. Evaluaciones de deterioracion poscosecha realizadas en 5 lugares de Colombia con diferentes condiciones edafoclimaticas, mostraron que entre las var. evaluadas existe un amplio rango de deterioracion en CIAT-Palmira y en Popayan, mientras que en la Costa Norte el grado de deterioracion fue considerablemente menor. Todas las var. se comportaron como resistentes en Carimagua. Se determino ademas que las var. MCol 1807 y MCol 22 son las mas susceptibles al deterioro antes, y las mas resistentes despues de la poda de la parte aerea.
