Traits mechanisms
Traits’ mechanisms were checked for each species under each treatment
and their combinations within monoculture, give us some variable results
(Fig. 5). F and N reduced the root weight ratio (RWR) of
WT (-33.91%, -37.73%) and WC (-83.4%,
-90.1%). F increased shoot weight ratio (SWR), relative growth rate of
dry weight (RGRB) and relative growth rate of shoot
(RGRS) of WT (33.9%, 87.2% and 94.2%)
and WC (83.4%, 29.6%, and 10%). N reduced the
RGRB, RGRS and RWR of WC(-59.9%, -18.1%, -90.2%). RGRB and
RGRS increased in
WT (79.3%, 94.5%). The
combination of flooding and
additional nitrogen (F.N, F.2N) decreased the RGRB of
WC (-94.25%, -92.0%), but increased the
RGRB of WT (42.0%, 33.9%) compared
with CK (Fig. 5).
