LMA showed highly significant positive correlations ( p < 0.01) with LA, Nmass, Narea, Pmass, Parea, Pn, Tr, Gs and WUE and highly significant negative correlations ( p < 0.01) with LWC and ci:ca ( Figure 6 and Figure 7 ).
LMA showed highly significant positive correlations ( p < 0.01) with LA, Nmass, Narea, Pmass, Parea, Pn, Tr, Gs and WUE and highly significant negative correlations ( p < 0.01) with LWC and ci:ca ( Figure 6 and Figure 7 ).
Second, according to the Pearson correlation analysis, both Pmass and Parea had extremely significant positive correlations with LA ( p < 0.01), indicating that LA was greatly affected by the phosphorus content in leaves.
The Nmass of female plants was significantly higher than male plants across the three field sites and there was an overall trend of higher Nmass with increasing altitude ( Figure 4 a,b).
