AN ASSESSMENT AND ENUMERATIONS OF VESICULARARBUSCULAR MYCORRHIZA PROPAGULES IN SOME FOREST SITES OF JENGKA

Abstract

Vesicular-arbuscular mycorrhizal spore numbers found in three representative forest areas in Jengka were low and well below those recorded in other tropical soils. However, levels of root infection in soil cores were comparatively high. Evidence showed that current forest logging practices influenced significant changes in vesicular-arbuscular mycorrhizal propagules. Propagules were reduced by 30-50 % when forest soils were severely disturbed through heavy soil mechanical compaction, exposure and erosion.
