Abstract:We measured total nitrogen (N) and total phosphorus (P) concentrations in leaves of Leymus chinensis,Phragmites communis and Lespedeza hedysaroides in Songnen Plain meadow,and analyzed their relationship with soil total N and total P concentrations. The results showed that foliar total N concentration differed significantly among three species (P<0.05),while foliar total P concentrations did not show significant difference (P>0.05). The leaf N concentration of the three species had no significant correlatio...
Keywords:N:P ratio  total N concentration  total P concentration  correlation
