  abstract: The feasibility of using seeds instead of vegetative
  abstract: transplants for establishing vegetation in constructed
  abstract: freshwater wetlands on the upper Texas coast was evaluated.
  abstract: Species examined consisted of Carex cherokeensis, Cyperus
  abstract: virens, C. pseudovegetus, Echinochloa crusgalli, E. walteri,
  abstract: Polygonum hydropiperoides, Rhynchospora corniculata, R.
  abstract: globularis, Rumex crispus, Sagittaria lancifolia, Scirpus
  abstract: pungens, and Sesbania macrocarpa. Seed germination in
  abstract: response to presence or absence of stratification and
  abstract: scarification with sprinkled or sprinkled/saturated water
  abstract: regimes was evaluated in a controlled outdoor growth
  abstract: environment. Seed germination in a constructed wetland was
  abstract: evaluated in response to stratification and scarification
  abstract: (presence/absence) with sprinkled or inundated water regimes
  abstract: (-3, 2, 7, 12, 17, and 22 cm flooding depths). Growth and
  abstract: survival of wild-collected and container grown transplants
  abstract: were evaluated at 6, 11, 16, 21, 26, and 31 cm water depths.
  abstract: In the growth environment, three species germinated well. C.
  abstract: virens germinated better in the wettest treatment, while E.
  abstract: crusgalli germinated best in the drier treatment. For S.
  abstract: macrocarpa, with its hard, waxy seed coat, scarification
  abstract: significantly increased germination of S. macrocarpa. In the
  abstract: constructed wetlands lack of constant soil moisture (in the
  abstract: sprinkled treatment) or excessive depth of flooding
  abstract: apparently caused poor germination in all study species
  abstract: except E. crusgalli, R. crispus, and S. macrocarpa. Best
  abstract: germination was without or with minimal (2 cm) flooding.
  abstract: Little germination occurred in water depths greater than 2
  abstract: cm. As before, scarification significantly increased
  abstract: germination of S. macrocarpa. Transplants of several of the
  abstract: study species were able to tolerate a wide variety of
  abstract: hydrologic regimes, with S. lancifolia and S. pungens being
  abstract: the most adaptable. For deeper habitats, P. hydropiperoides
  abstract: did fairly well, while R. corniculata and C. pseudovegetus
  abstract: did well at the shallower depths. C. cherokeensis and R.
  abstract: globularis were not Suitable for the water depths studied.
  abstract: For the Echinochloa species, it appears to be important that
  abstract: the water level be maintained below the tops of the plants
  abstract: while they are immature. Overall, of the species studied, E.
  abstract: crusgalli and S. macrocarpa, both annuals, were best suited
  abstract: for seeding constructed wetlands due to their relatively high
  abstract: germination percentages and rapid germination and growth.
