Degradation Efficacy of Pinus radiata
Don Needle Leaf, Twig and Bark
by Wood Degrading Fungi in Forest
Ecosystem
M. N. Abubacker and M. Prince
Abstract The degradation of lignin, holocellulose and hot water soluble content of
Pinus radiata needle leaf, twig and bark by wood degrading fungi was studied in
virgin forest ecosystem of Doddabetta, Nilgiris for a period of 180 days. The study
revealed that the maximum percentage of lignin degradation of needle leaf material
with Heterobasidium annosum was 8.8, twig with the same fungus was 18.3, and
the bark with 19.5. For holocellulose needle leaf degradation with a maximum of
10.3 for Thelopora terrestris fungus for twig with the same fungi shows 12.1 and
for bark Polyporus squamosus with 16.9 of degradation. Hot water soluble content
was maximum of 18.7% with Colricia perennis fungus for the needle leaf, for twig
10.5% for the same fungi and for bark with 9.0% for Polyporus squamosus for a
period of 180 days. The elemental status of mixed samples of needle leaf, twig and
bark constitute the forest litter of P. radiata were inoculated with H. annosum, T.
terrestris, P. squamosus and C. perennis mycelia. The SEM–EDX analysis revealed
the maximum availability of elements at 180 days of degradation when compared
with initial stage.

1 Introduction
Forests represent approximately 27% of the world’s land area and wood is the
predominant, commercial product from forests. Wood is used for the manufacture
of wood-based products. Logging operations in forests usually generate abundant
amounts of waste such as residual wood, branches, twigs, leaves and bark. The
