Effects of manipulation of litter and humus layers on ectomycorrhizal colonization potential in Scots pine stands of different age

Abstract

Effects of manipulation of litter and humus layers (removal, doubling and control treatments) on the colonization potential of ectomycorrhizal fungi were studied in two secondary stands of Pinus sylvestris (5 and 18 years old) in The Netherlands. Five-mont-hold, sterile-grown Scots pine seedlings, inoculated with Laccaria bicolor, Paxillus involutus or Rhizopogon luteolus and noninoculated seedlings were used as baits. The seedlings were harvested after one growing season. For comparison, sporocarps of ectomycorrhizal fungi were also investigated. Genus composition on the seedlings was independent of initial inoculum, but determined by both treatment and age of the stands. In both stands, removal of litter and humus layers increased, and addition of organic material decreased the number of ectomycorrhizal types on the seedlings. Not all indigenous genera were observed by either outplanting seedlings or sporocarp surveys.
