Ho Y. W., . and Khairudin H., . (1999) Histopathology of oil palm seedlings infected by Ganoderma boninense. [Proceedings Paper]
Abstract
Oil palm seedlings inoculated with Ganoderma boninense culture showed external disease symptoms3monthsafterinoculation and 15ofthepalmsdiedwithin5months. Infection ofthepalms was by root contact with the inoculum. When the root was infected by an external inoculun the sequence of infection was from the epidermis inwards towards the central vascular cylinder i.e. the infection of the epidermal and cortical layers always preceded the infection of the vascular tissues. However when infection was from an infected root to a connecting root the infection of the vascular tissues could precede that of the epidermal and cortical cells. Infected cells were lignified and were often filled with hyphae or occluded with gum and other deposits. Infection of the stem was initiated at the connections between the infected roots and the stem. Histopathological responses of infected tissues in the stem were similar to those in the roots. Ganoderma boninense was re-isolated from the diseased roots and stems of all infected and dead palms but not from the control palms or the symptom-free inoculated palms.
