THE MYCORRRHIZAL STATUS
IN MOUNTAINOUS VEGETATION IN THE FAROE ISLANDS
lar mycorrhizal plant species and ecto- or
ericoid plant species could be due to dual
infection, but that can not be concluded
from this study.
The fact that the type which requires
least photosynthetic products from the
plant, and is Ieast efficient in degrading or-
ganic compunds is the most widespread
could indicate that there are other factors
than phosphorus and nitrogen which are
limiting. These could be, for example, tem-
perature and/or light.
Acknowledgments
We thank Professor A.H. Fitter for his helpful criticism
of an earlier draft of the manuscript, and P.H. Enkell for
his helpful review of the manuscript. Financial assis-
tance from Granskingarráð Føroya, Danish Research
Councils and the Faroese Museum of Natural History
made this study possible.
