AB  - Atmospheric nitrous oxide (N(2)O) increase contributes substantially to global 
      climate change due to its large global warming potential. Soil N(2)O emissions 
      have been widely studied, but plants have so far been ignored, even though they 
      are known as an important source of N(2)O. The specific objectives of this study 
      are to (1) reveal the effects of nitrogen and biochar addition on plant 
      functional traits and N(2)O emission of Cinnamomum camphora seedlings; (2) find 
      out the possible leaf traits affecting plant N(2)O emissions. The effects of 
      nitrogen and biochar on plant functional traits and N(2)O emissions from plants 
      using C. camphora seedlings were investigated. Plant N(2)O emissions, growth, 
      each organ biomass, each organ nutrient allocation, gas exchange parameters, and 
      chlorophyll fluorescence parameters of C. camphora seedlings were measured. 
      Further investigation of the relationships between plant N(2)O emission and leaf 
      traits was performed by simple linear regression analysis, principal component 
      analysis (PCA), and structural equation model (SEM). It was found that nitrogen 
      addition profoundly increased cumulative plant N(2)O emissions (+109.25%), which 
      contributed substantially to the atmosphere's N(2)O budget in forest ecosystems. 
      Plant N(2)O emissions had a strong correlation to leaf traits (leaf TN, P (n) , G 
      (s) , C (i) , Tr, WUE (L) , alpha, ETR (max), I (k) , Fv/Fm, Y(II), and SPAD). 
      Structural equation modelling revealed that leaf TN, leaf TP, P (n) , C (i) , Tr, 
      WUE (L) , alpha, ETR (max), and I (k) were key traits regulating the effects of 
      plants on N(2)O emissions. These results provide a direction for understanding 
      the mechanism of N(2)O emission from plants and provide a theoretical basis for 
      formulating corresponding emission reduction schemes.
