Mycorrhizae: Facts and Fallacies    (View PDF)

J.G. Iyer, R.B. Corey and S.A. Wilde

Abstract: This paper points out the ephemeral nature of mycorrhizal short roots, influenced in their development by radiation, soil drainage, and eradicants. Emphasis is placed on rhizospheric and extramatrical mycelia as agents enriching soils in enzymes, chelates, and available nutrients. Inoculations of soil, seed, or stock with mycorrhiza-forming fungi without ascertaining the supply of major and minor nutrients and the soil's freedom from toxic substances will inflict financial losses and undermine the program. Inoculation of biocideimpaired nursery soils usually necessitates addition of suitable energy material and adjustment of soil fertility. Suggestions are made for clarification of conceptual discrepancies relevant to tree-fungus symbiosis.
