Explorations of mechanisms regulating ectomycorrhizal colonization of boron-fertilized pine

Research continued on the following tasks: to determine the effects of hydroxylation of phenolic compounds on the growth of Pisolithus tinctorius, a known ectomycorrhizal fungus, grown in pure culture; to evaluate the effectiveness of phenolase in metabolizing the most and least toxic phenolic compounds studied; and to determine the types and quantities of phenolic compounds produced by pine seedlings inoculated with Pisolithus tinctorius and receiving boron fertilization. 1 fig., 2 tabs.
