This progress report describes efforts to determine if boron and IAA applied in combination to the roots of nonmycorrhizal shortleaf pine seedlings results in a greater downward flux of sucrose than when each is applied independently; to evaluate ectomycorrhizal-created endogenous increases of auxin (IAA) in shortleaf pine root systems receiving boron supplements and determine if the impact on carbohydrate flux resembles that in plants receiving exogenous boron and IAA; 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. Additional topics will be studied in future reports. 14 refs., 2 tabs.
