Decay in the standing temperate conifers of Kaghan
Decay in the standing temperate conifers of Kaghan
Zakaullah
ABSTRACT
A study of 203 conifer trees revealed that the incidence of decay was 16.3% and extent of volume loss 1.7% among all the sample trees. Phaeolus schweinitzii and Phellinus pini were the two major decay fungi causing brown cubical and red ring rot respectively. They accounted for 94% of the total decay volume. No consistent relationship was indicated between decay and age of the tree. Decay volume percent was higher on northern as compared to southern aspects. Mechanical basal injuries and dead branch stubs were the important infection courts for the decay pathogens.
