Abstract
|
|
|
Emission rates of biogenic hydrocarbon emitted from broad-leaved trees grown at Jeju Island were estimated using a
dynamic enclosure method. Leaf temperature, PAR and relative humidity were monitored during the sampling time. The
emission rates of isoprene and monoterpene were measured for five plants(Carpinus laxiflora, Quercus serrata, Styrax
japonicus, Quercus acutissima, Quercus crispula) during the sampling period at the Halla mountain sites. Among five tree
species, the highest isoprene emission rate of 10.60 ㎍ gdw-1hr-1 was observed for Quercus serrata. The seasonal emission rates were the highest during summer and the emission of isoprene was highly affected by light and temperature variations.
The highest emission rate of isoprene was occurred between 13:00 and 14:00, but isoprene was not emitted in nighttime
because of the absence of light.
