Conclusions
Functional traits of WT and WC played
important role for the success of their growth under nitrogen enrichment
and flooding conditions. According to the results, dry weight, and
morphological traits of WT were significantly higher
than WC under combination of flooding and additional
nitrogen (F.N and F.2N), due to higher resource acquisition ability of
WT over WC. LN and CHI of
WT was significantly lower than WC; this
may confer higher resistance to WT under the adverse
environments. Higher phenotypic plasticity and negative effect of
competition of WT over WC under
combination of flooding and additional nitrogen (F.N and F.2N), make
WT more successful within these complex environments.
This study helped us to understanding the role of functional traits for
the successful invasion of invasive plant species.
