Se realizo un expt. para estudiar la asociacion micorrizal en cultivos de tuberculos. Se recolectaron muestras de yuca, batata (Ipomoea batatas), Dioscorea sp., Colocasia sp., Amorphophallus sp. y Coleus sp. de la granja agricola del Central Tuber Crops Research Institute. Se recolectaron muestras de la rizosfera del suelo de todos los cultivos de tuberculos, para determinar la presencia de esporas en el suelo. La intensidad de la infeccion en las raices se determino con base en observaciones microscopicas de muestras tenidas, las cuales revelaron la presencia de la asociacion micorrizal tipica VA en las muestras de raices de yuca, coleo y batata, mientras que en los otros cultivos no se observaron ni vesiculas arbusculares ni micelio externo. La rizosfera del suelo de yuca, coleo y batata presento un no. de esporas con diferentes tonos de color, las cuales tenian varias morfologias perifericas. El Endogone sp. que se observo en esta investigacion esta involucrado en el tipo de asociacion micorrizal VA con raices de yuca, coleo y batata. (CIAT) spa
An expt. was conducted to study the mycorrhizal association in tuber crops. Samples of cassava, sweet potato (Ipomoea batatas), Dioscorea sp., Colocasia sp., Amorphophallus Sp. and Coleus sp. were collected at the Central Tuber Crops Research Institute farm. Rhizosphere soil samples from all the tuber crops were collected to determine the presence of spores in the soil. The intensity of infection in the roots was determined on the basis of microscopic examinations of stained samples, which revealed the presence of typical VA mycorrhizal association in root samples of cassava, coleus, and sweet potatoes while neither vesicles arbuscules nor external mycelium was observed in other crops. Rhizosphere soil of cassava, coleus, and sweet potatoes presented a no. of spores with different color shades having various peripheral morphologies. Endogone sp., observed during this investigation, was involved in VA mycorrhizal type of association with cassava, sweet potato and coleus roots. (CIAT) eng
