abstract = {Selection pressure of flooding promotes the development of
phenotypic plasticity of riparian plants; however, whether
the selection effects of flooding are elevation-dependent
still remains unclear. Seeds of the riparian species
Polygonum hydropiper were collected from 10 different
locations each at low and high elevations in the Three
Gorges Reservoir Region. Plants germinated from these seeds
were subjected to control and flooding treatments. Flooding
significantly increased both specific leaf area (SLA) and
adventitious root biomass but decreased other growth traits
of all progeny. In response to flooding, plasticity of all
leaf and root traits except SLA varied significantly among
seed families (seedlings emerged from the same mother plant)
from low elevation. However, among seed families from high
elevation, plasticity of only leaf number, total leaf area,
and adventitious root biomass varied significantly. For
low-elevation seed families, benefits of plasticity in leaf
width, leaf number, average leaf area, and leaf biomass were
detected across control and flooded conditions. However, in
response to flooding, significant costs of plasticity in
leaf length, leaf width, average and total leaf areas were
found. Therefore, selection effects of flooding impose great
pressure on plasticity of leaf and root traits of
low-elevation seed families, which is elevation-dependent.},
