| Abstract |
There is a growing awareness about the role of vegetation as a source of reactive hydrocarbons that may serve as photochemical oxidant precursors. A study was designed to access the influence, independently, of variable light and temperature on isoprene emissions from live oak. Plants were contained in a growth chamber, then transferred to an environmentally controlled gas-exchange chamber. Samples of the chamber atmosphere were collected, isoprene was concentrated cryogenically and measured by gas chromatography. The logistic function was used to moadel sioprene emission rates. |
