Anatomical studies on decaying wood of Mangifera indica by two white rot fungi Schizophyllum commune and Flavadon flavus
Tóm tắt
Basidiomycetes fungi Schizophyllum commune and Flavadon flavus very commonly cause white rot decay in felled trees. The pattern of wood decay caused by two fungi viz. S. commune and F. flavus in Mangifera indica wood is investigated using light and scanning electron microscopy. Samples inoculated with S. commune and F. flavus exhibited a combination of simultaneous decay and selective delignification. Separation or loosening of cells was the characteristic feature for selective decay, while presence of erosion troughs, reduction in cell wall thickening, bore holes, erosion channels were diagnostic features for simultaneous type of decay. Infected samples of S. commune showed separation among cells followed by cell wall thinning and presence of erosion troughs. In contrast F. flavus infected wood initially showed presence of bore holes and erosion channels followed by simultaneous loosening of cells.
