Abstract: 

Non-inoculated spruce seedlings (Picea abies Karst.) and spruce
seedlings colonized with Lactarius rufus Fr., Pisolithus tinctorius
Coker & Couch or Paxillus involutus Fr. were grown for 35 or 37
weeks in a system on two types of natural forest humus differing in Pb
content. Using X-ray microanalysis, the distribution and content of Pb
in the tissues of mycorrhizal and non-mycorrhizal root tips were
compared. No significant difference in the Pb contents of root cortex
cell walls of non-mycorrhizal and seedlings colonized by Lactarius
rufus, Pisolithus, or indigenous mycorrhizal fungi (mainly Tylospara
sp.) was found. However, in root tips of seedlings colonized by Paxillus
involutus, due to a higher binding capacity for cations, the Pb content
in cell walls of the root cortex were higher than in non-mycorrhizal
roots. Pb contents in cell walls of the cortex of mycorrhizal and
non-mycorrhizal roots were 3 times higher in plants growing in humus
with a high Pb content than in plants growing in humus with a low Pb
content. It is concluded that increasing contents of Pb in the organic
matter may lead to an increased loading of the apoplast with Pb. The
mycobionts tested in this investigation did not exclude Pb from root
tissues.
