Using GC- PID, the isoprene emissions of Eucalyptus urophylla were measured in March. At the same time, the net photosynthetic rate, transpiration rate, stomatal conductance, intercellular CO2 concentration of leaves and other correlative environmental factors were measured by LI-6400 portable photosynthesis system. The isoprene emissions of E. urophylla were also studied, after cutting branches. The results showed that the changes of isoprene emissions appeared single peak in the daytime, with the maximum appeared at 14:00 around, and the isoprene emissions decreased after cutting branches.
