Abstract |
The variation in response of terpenoid emmissions to light and temperature were studied for two closely related spruce species, Engelmann(Picea engelmannii) and Sitka(Picea sitchensis). Isoprene was the major terpenoid emitted, accounting for approximately 75 and 69 percent of the terpenoid emissions from Engelmann and Sitka spruce, respectively. However, Sitka spruce emitted isoprene at about 1/5 the rate of Engelmann spruce. Isoprene emissions increased with light and temperature in both species, but the light response was much less in the Sitka than in the Engelmann spruce.
