ABSTRACT. Biological invasion represents a global issue of concern due to its large negative impacts on native ecosystems and society. Tel: (800) YOUR-BAY (968-7229) The seed sprouts within the mud and becomes a seedling After Spartina alterniflora was sampled, we took Spartina alterniflora to the Yellow River delta management stations for pre-incubated. xref Spartina grass (Spartina alterniflora), also known as marsh grass or smooth cordgrass, is very abundant in the saltmarsh. Smooth cordgrass is also known as saltmarsh cordgrass. Although the settlement of S. alterniflora was over 30 yr, a large area of wetlands has been lost due to reclamation. Reproduction and Life Cycle. The life cycle of Spartina grass begins with a seed in the fall. It grows in low-lying, salt and brackish tidal marshes along the shores of the middle and lower Chesapeake Bay.

Fax: (410) 267-5777, © 2021 Chesapeake Bay Program All Rights Reserved Spartina alterniflora was introduced to China in 1979 from three low‐latitude sites (Florida, Georgia, North Carolina) in the United States and propagated in a common garden (Guo et al., 2015; Liu et al., 2019). Spartina alterniflora (Spartina) is the only halophyte in the salt marsh.However, the molecular basis of its high salt tolerance remains elusive. In specific it grows in salt marsh, mud flat, and sand flat habitats. This plant can live in saltwater by excreting salt and also deal with the harsh changing tides. 0000001977 00000 n The grass becomes dense and forms a baffle, which encourages the deposition of fine particulate sediment, including organic matter (salt marsh peat). Smooth cordgrass forms dense colonies that usually run parallel to the shoreline.

SPECIES: Spartina alterniflora GENERAL BOTANICAL CHARACTERISTICS : Smooth cordgrass is a large, coarse, warm-season grass, which is physiologically adapted to the salt marsh habitat [ 26 , 27 ]. of Spartina can reduce mean water velocity by 50% and maximum velocity by nearly an order of magnitude, and they can substantially stabilize the cobble substrate. The leaves leaves grow 12 to 20 inches in length and one-half an inch wide. Spartina alterniflora has become one of the dominant species in the coastal wetlands in China due to its unique physiological and ecological characteristics (e.g., higher growth rate, higher net primary yield, and higher salt tolerance) compared to native plants [13,14].
