Perry, David A.; Choquette, Carolyn. 1987. Allelopathic effects on mycorrhizae: influence on structure and dynamics of forest ecosystems. In: Waller, George R., ed. Allelochemicals: role in agriculture and forestry. ACS Symposium Ser. 330. Washington, DC: American Chemical Society: 185-194.
Ectomycorrhizal species differ in their sensitivity toallelochemicals originating in litter and soil organicmaterial. This phenomenon produces a successionalchange in mycorrhizal species as ecosystems rebuildlitter layers following disturbance, and possibly actsto structure rooting zones in such a way thatcompetition among higher plants is decreased.
Mycorrhizae alter foliage chemistry, and thuspotentially form a closed loop in which they both acton, and are acted upon by, system biochemistry.
