Interaction Processes of Environment and Plant Ecophysiology with BVOC Emissions from Dominant Greening Trees

In global greening, biogenic volatile organic compound (BVOC) emissions and their influencing factors have been considered due to significant roles in the biosphere atmosphere. Many studies reported relationships of BVOC with environmental plant ecophysiology. However, direct indirect effects on remain unclear, causal between ecophysiology are ambiguous. We measured isoprene monoterpene from dominant greening plants using a dynamic enclosure system quantified interactions environment–-plant ecophysiology–BVOC path analysis model. found that emission was directly affected by photosynthetic rate, indirectly photosynthetically active radiation air temperature (Tair). Monoterpene were atmospheric pressure, relative humidity specific leaf weight, Tair.
