Anatomical changes in Syzygium cumuini Linn. wood decayed by two white rot fungi Schizophyllum commune Fries. and Flavodon flavus (Klotzsch) Ryvarden
Tóm tắt
The purpose of this work was to study the anatomical changes occurred in the Syzygium cumuini Linn. wood decayed by two white rot fungi Schizophyllum commune Fries. and Flavodon flavus (Klotzsch) Ryvarden. Anatomical studies have revealed that both the fungi penetrate the wood through pit apertures. S. commune breaks down cellulose and hemicellulose first with the lignin remaining which degrades later. F. flavus preferentially degrade lignin. Bore holes were distinctly formed in the secondary wall, breaking the fiber tracheid into radial cracks. Axial and ray parenchyma cells are degraded first followed by the lignified xylem elements, tracheids and vessels. Observation of light microscopic study has been supplemented with scanning electron microscopy.
