abstract = {The capacity for fast-growth recovery after de-submergence
is important for establishment of riparian species in a
water-level-fluctuation zone. Recovery patterns of two
wetland plants, Alternanthera philoxeroides and Hemarthria
altissima, showing 'escape' and 'quiescence' responses,
respectively, during submergence were investigated.Leaf and
root growth and photosynthesis were monitored continuously
during 10 d of recovery following 20 d of complete
submergence. Above- and below-ground dry weights, as well as
carbohydrate concentrations, were measured several times
during the experiment.Both species remobilized stored
carbohydrate during submergence. Although enhanced internode
elongation depleted the carbohydrate storage in A.
philoxeroides during submergence, this species resumed leaf
growth 3 d after de-submergence concomitant with restoration
of the maximal photosynthetic capacity. In contrast, some
sucrose was conserved in shoots of H. altissima during
submergence, which promoted rapid re-growth of leaves 2 d
after de-submergence and earlier than the full recovery of
photosynthesis. The recovery of root growth was delayed by
1-2 d compared with leaves in both species.Submergence
tolerance of the escape and quiescence strategies entails
not only the corresponding regulation of growth,
carbohydrate catabolism and energy metabolism during
submergence but also co-ordinated recovery of
photosynthesis, growth and carbohydrate partitioning
following de-submergence.},
