Histopathology of sweetpotato roots infected with Meloidogyne incognita
O.S. Osunlola† and B. Fawole1
ABSTRACT
Meloidogyne incognita infected roots of sweetpotato (Ipomoea batatas (L.) Lam.) were observed for histopathology
changes included cellular disorganization in the root cortex, endodermis and vascular cells. Female nematode
displaced root cells and occupied large cavities and the surrounding cells were compressed. The nematode induced
formation of an average of four giant cells each with 7 ± 0.5 nuclei around the head of nematode close to vascular
cells. Nematode eggs were seen in the cortical cells but more eggs were recorded near the root surface. Multiple
infections were also observed.
