Seasonal variation of isoprene basal emission in mature Quercus crispula trees under experimental warming of roots and branches
isoprene biogenic volatile emission Quercus crispula experimental warming
2017/4/11
Isoprene is a reactive volatile organic compound (VOC), the annual global biogenic emissions of which are the largest
of the non-methane VOC. Since isoprene emissions are partly temperature-driven, u...
