Popis:	Aldehydes, a group of volatile organic compounds (VOCs) often detected in the atmosphere, play a key role in atmospheric chemistry and plant resistance to stresses. We used gas chromatography/mass spectrometry to examine the volatiles of saturated aldehydes C6–C10 that were emitted from cuttings of ashleaf maple (Acer negundo L.) under varying levels of light intensity (80, 400, and 800 μmol m−2 s−1), O2 (2% and 50%), and CO2 (600, 1,000, and 1,200 ppm). An apparent, positive correlation was found between light intensity and emissions, and their release also was significantly enhanced by higher O2 concentrations. In contrast, emissions clearly were negatively correlated with CO2 levels. We speculate that the reactive oxygen species (ROS) generated during photosynthesis contribute to these elevated emissions. However, the mechanism for this ROS trigger is unknown.
