Technical Abstract: Pinus taeda L., loblolly pine, is one of the most valuable and widely cultivated timber species in the southern USA for lumber and pulpwood. Techniques to enhance seedling growth may reduce the nursery time. Fungal elicitors are known to affect the secondary metabolism in plants. We report the effects of various fungal elicitors on growth and secondary metabolism in P. taeda. Plants grown in greenhouse and exposed to a number of fungal elicitors showed significant increases in fresh weight, leaf and root number, and shoot length over control (P=0.05). This effect was not dose dependent, although we have not determined the minimum dose yet. Total secondary metabolite alpha-pinene was greater in treated seedlings due to increased fresh weight. Fungal elicitors may improve the growth and secondary metabolism in plants.
