Influence de la mycorhization et de la fertilisation sur le comportement de jeunes plants d'érable sycomore (Acer pseudoplatanus Link.)

Influence of mycorrhizae and fertilization on Acer pseudoplatanus seedlings . A greenhouse experi-ment compared growth and mineral nutrition of Acer pseudoplatanus seedlings on two soils with different fertilizations and with different endomycorrhization treatments. A strain of Glomus mosseae and a mycorrhizal complex from an A. pseudoplatanus stand prove to be much more growth efficient than the natural inoculum of the soils, mainly by improving phosphorus nutrition. These effects are additive to those of fertilization. This last result suggests that controlled mycorrhization can be of great practical interest even on rich soils.
