title: Changes in terpene production following nitrogen fertilization of grand fir (Abies grandis (Dougl.) Lindl.) seedlings.
abstract: Of ten terpenes that comprise most of the volatiles of grand fir foliage only four were affected by addition of nitrogen. Levels of beta-phellandrene, camphene and bornyl acetate and terpinolene were significantly reduced with nitrogen added to the equivalent amount of 44.8 g/m2. A quantity of 22.4 g/m2did not affect terpene production. Several populations were examined and these did not respond consistently on a regional basis, yet a significant interaction effect was apparent between treatment and local population response. Overall, total yield of terpenes as a function of fertilization was not altered.
