Abstract There is a growing awareness concerning the role of vegetation as a source of reactive hydrocarbons that may serve as photochemical oxidant precursors. This study assessed the influence, independently, of light and temperature on monoterpene emissions from slash pine (Pinus elliottii Engelm). Plants were pre-conditioned in a growth chamber then transferred to an environmentaly controlled gas-exchange chamber. After samples of the chamber atmosphere were collected, the monoterpenes were concentrated cryogenically and measured by gas chromatography. Five monoterpenes, alpha-pinene, beta-pinene, myrcene, limonene and B-phellandrene were present in the vapor phase surrounding the plants in sufficient quantity to measure reliably. Light did not directly influence monoterpene emission rates since emissions were similar in the dark and at various light intensities. Monoterpene emission rates increased exponentially with temperature (i.e., emissions depend on temperature in a log-linear manner). The sum of the 5 monoterpenes ranged from 3 to 21 micrograms C/g dry wt/hr as temperature was increased from 20 to 46C.
