ULTRASTRUCTURAL STUDIES OF CONIDIOGENESIS OF ASCOCHYTA-RABIEI, THE CAUSAL ORGANISM OF CHICKPEA BLIGHT

Studies employing transmission (TEM) acid scanning (SEM) electron micr oscopy revealed that conidiogenous cells of the chickpea blight fungus , Ascochyta rabiei (Pass.) Labr., resembled phialides in most of their features. The phialides were generally of a simple type, but occasion ally they proliferated in a percurrent fashion. There is enough eviden ce to suggest that the fungus is better placed in genus Phoma. SEM has been employed for the first time to study internal details of fructif ications of a dosed type in coelomycete fungi.
