Abstract

Foliar phosphorus content and mycorrhizal infection of dipterocarp seedlings growing in a 61-year-old forest plantation (site A) and a selectively logged forest (site B) were determined. Mycorrhizal infection levels were high−83.7% forShorea bracteolata and 95.0% forS. leprosula at site A, and 77.8% forS. leprosula and 86.3% forS. curtisii at site B. The seedlings all had similar foliar phosphorus contents although available soil phosphorus at site B was half that at site A. Significant correlations were obtained between foliar phosphorus content and percentage mycorrhizal infection at site B only.
