Abstract
The host-pathogen relationship between the Raphia hookeri seedling leaf and Glomerella cingulatashowed that the host cells were macerated. This allowed penetration of the pathogen through the hypodermis to the palisade tissue which resulted in dark coloration and disruption of the transfusion tissues. Hypersensitivity reaction was observed. The xylem and phloem were left without any attachment or support. Their intact cells were darkened as a result of disease development which resulted in complete disintegration of the palisade tissues and disappearance of transfusion cells. The uninoculated seedling leaf remained healthy with glossy appearance.
Key words: Glomerella cingulata, Raphia hookeri, seedling blight.
