Abstract. Isoprene emission by plants is the principal source of photochemically active reduced compounds in the troposphere, and tropical forest ecosystems are the largest single source of isoprene. The oxidation of isoprene plays a major role in controlling the redox potential of the troposphere and the dynamics of carbon monoxide, ozone, and methane. We used a combination of infrared gas analysis and gas chromatography/photoionization detection in the first study of isoprene emission and photosynthesis from canopy leaves in a tropical wet forest under controlled light and temperature conditions. Twelve of the 33 tree species surveyed produced isoprene. This is a similar ...
