Release Variation and Antibiotic Functions of Volatile Organic Compounds from Populus alba×P, berolinensis
Composition of volatile organic compounds (VOCs) emitted from Populus alba × P. Berolinensis and its seasonal variance were studied by SUMMA canister and GC-MS analysis. The effects of VOCs from P. Alba x P. Berolinensis on inhibiting the airborne microbes were examined by the settling plate technique. Results show that the major VOCs from P. Alba × P. Berolinensis are alkenes and alkanes. 1-pentyne is dominant in spring and autumn, and 2-chloro-l-propene is dominant in summer. The terpenes mainly include D-limonene and a-pinene in spring and autumn, as well as caryophyllene and cam phol in summer. VOCs emitted from P. Alba x P. Berolinensis can effectively inhibit the growth of airborne microbes, and the effect is the most obvious in summer.
