OSTI ID:20002128
A flow-through plant enclosure method was used to collect VOCs emitted from soybeans (Glycine max) grown at the Biological Sciences Center at the Desert Research Institute. Samples of leaf emissions were collected on Tenax-Carbosieve cartridges and analyzed by gas chromatography-mass spectrometry at the Organic Analytical Laboratory at DRI. Samples of VOCs were also collected in 6 liter stainless steel canisters and analyzed by gas chromatography-flame ionization detection. Among the VOCs observed were {alpha}-pinene and limonene. The soybeans were grown in two plant enclosures with carbon dioxide levels of 250 ppm and 1,000 ppm. Leaf emissions from soybeans grown in the enclosure with 250 ppm CO{sub 2} showed higher concentrations of {alpha}-pinene, while limonene concentrations remained unchanged.
