Abstract
Balsam fir (Abiesbalsamea (L.) Mill.) seedlings inoculated with Cenococcumgeophillum Fr. isolate 145A, Hebelomacrustuliniforme (Bull, ex Saint-Amans) Quel, isolate S166, and Laccarialaccata (Scop, ex Fr.) Bk. and Br. isolate 238B were grown in a split-plot factorial design with pH as main plots and Al concentration and ectomycorrhizal fungal species as subplots. No Al, 50 mg Al/g substrate, and 100 mg Al/g substrate were added to the potting soil mixture, which was adjusted to a final pH of 3, 4, or 5. The seedlings were watered with one-fifth strength Arnon's solution having a pH of 3, 4, or 5 and containing 100, 50, or 0 mg Al/L. The experiment was conducted to determine the effect of acidity and concentration of Al on ectomycorrhizal formation. As solution acidity and concentrations of Al increased, ectomycorrhizal formation, root weight, shoot weight, total weight, root:shoot ratio, and B concentration decreased; however, concentrations of Fe, Mn, P, and Zn in the seedlings increased. N, Ca, K, and Mg concentrations did not vary significantly in any of the treatments. Results of this study suggest that pH and Al have a complex effect on ectomycorrhizal formation and nutrient uptake in A. balsamea seedlings.
