Abstract

The effects of ammonium sulphate and sodium nitrate on Pinus sylvestris seedlings inoculated with Paxillus involutus and Suillus bovinus were investigated. Weekly fertilization (26 weeks) positively affected the plant dry weight, but inhibited the mycorrhizal formation and decreased the root length/weight ratio. Ammonium treatments affected the seedlings more positively and the mycorrhizas more negatively than nitrate did. The effects on seedlings inoculated with P. involutus were more pronounced than on those inoculated with S. bovinus. The possible mechanisms of the effects of nitrate and ammonium on mycorrhizas are discussed.
