ABSTRACT
This paper firstly measured in situ N2O emission from branches and leaves of sun plants (Fraxinus mandshurica, Pinus koraiensis, Alnus hirsuta) and shade tolerant plants (Tilia amurrensis) under different light irradiances in closed chamber. Light irradiance had contrast effects on N2O emission flux from sun and shade-tolerant tree species. In the test sun plants, more N2O was emitted under weak light than under strong light. The emission rates decreased with increasing irradiances, and even absorption instead of emission of N2O was detected under strong light. In contrast to sun plants, in the shade tolerant plant T. amurrensis, there was more N2O emission under strong light than under weak light, and N2O absorption from environment was detected under weak light.
