Hystopathological and histochemical changes due to Rhizoctonia solani infection in coffee seedlings
Rhyzoctonia solani, the collar rot pathogen of coffee seedlings, penetrate the host tissue forming infection cushion and infection pegs. The fungal spread was both inter and intracellular. Among various tissues, epidermis and cortex were more vulnerable to fungal invasion. The establishment of the pathogen lead to the formation of sclerotia in the cortex. Distortion of the collar tissue and formation of cavities in the cortex was the common anomaly. The histochemical analysis of the infected collar tissues indicated reduction in insoluble polysaccharides, starch, protein and nucleic acid content
