摘要: Plant species release appreciable quantities of volatile organic substances to the atmosphere. The major compounds emitted are monoterpenes (C10) like α-pinene, β-pinene, and limonene hemiterpene (C5) isoprene. rate emission isoprene is light dependent ranges between 0.04 2.4 ppb/cm2/min/l for oak, cottonwood, eucalyptus foliage. a- and/3-pinene on transpiration, structural integrity oil cells resin glands, temperature Rates conifer foliage range from 0.4 3.5 ppb/g/min/l. An inventory North American forest regions frequency occurrence these chemicals released by different tree showed that 15% was lowest value a specific forest-type terpenes More commonly 100% trees given average 70% typical United States forested as wh...
