AB  - In this study, researchers used <I>Populus yunnanensis</I>, 
  a native precious poplar species which is only distributed in Southwestern China 
  as a model species to study its morphological, physiological and biochemical 
  responses to the interaction of different concentrations of nitrogen and Cd, 
  discussing the detoxification effect of nitrogen to Cd stress in<I> Populus 
  yunnanensis</I>. The treatments were consisted of three Cd levels (0, 2 and 
  4 mg kg<SUP>-1</SUP>) and three N levels (0, 20 and 40 mg kg<SUP>-1</SUP>). 
  After 40 days treatment, the results indicated that at the same N level, Cd 
  treatment had significant effect on all measured parameters, including plant 
  growth, chlorophyll concentration, Malondialdehyde (MDA) concentration, antioxidant 
  enzymes activities (SOD, POD, CAT and APX) and free proline. Meanwhile, study 
  also showed there was significant difference among the three levels of N treatment. 
  With the increasing concentration of N supplement, it showed more significant 
  effect of alleviation to Cd induced damage in <I>Populus yunnanensis</I>.
