The maximum rate of nitrogen uptake, calculated from rates of growth, is near 8 mg nitrogen/g dry weight of salvinia/day or about 6,000 kg nitrogen/ha/year (Room, 1986). The heterosporous fern clade, of which Salvinia minima is a part, contains two families, Marsileaceae and Salviniaceae. The leaves are of two types—oval ones that float on the water’s surface and dissected ones that hang beneath the plant and look like roots.

In late spring, existing plants can provide floating mats … Madsen, J.D, R.M. Viner. ... S. minima is a highly competitive species with a very high growth rate. Salvinia minima , a fast growing free-floating fern found in tropical and temperate regions, was chosen for the present study based on its ability to tolerate high hexavalent chromium concentrations [31] . Four hairs are joined at the tips and resemble a wisk. Biomass weights of live plants approach those recorded for floating waterhyacinth (Eichhornia crassipes (Mart.) Bister, T.J., and M.W. 2009.

Jacono, M.M. http://www.flmnh.ufl.edu/herbarium/. In Texas and Louisiana, S. minima typically occurs in dense, expansive populations and is known as a very troublesome weed. These water ferns are the only group of heterosporous plants to have evolved heterospory after the Paleozoic. Extirpated from colder climate states (Connecticut, District of Columbia, Kansas, Missouri, Virginia) and eradicated from Northern Alabama and California, and parts of the Carolinas, Florida, and Texas. Asian countries have supplemented livestock fodder with S. molesta, and utilized it as a compost and mulch (Oliver 1993; Thomas and Room 1986). 2006. http://www.anstaskforce.gov/Species%20plans/Giant%20Salvinia.pdf (accessed on November 12, 2006). More than 99% of the Pascagoula River population was killed by storm surge salinity or by being deposited on land during Hurricane Katrina in 2005, thus leaving about 2 hectares of. Salvinia minima is a very undemanding, nice floating plant for aquaria that grows well under moderate light. Sold as a small loose portion. Vegetative reproduction, rapid growth rates and dispersion by humans and flooding are major factors in the formation of dense mats of this weed. The optimum temperature for growth is 30°C. It is being provided to meet the need for timely best science. Salvinia molesta has the potential to alter aquatic ecosystems in several ways. Journal of Applied Ecology 935-944. University of West Alabama, Livingston, Alabama. The resulting structures resemble tiny eggbeaters.

Created on 11/24/2015. The Journal of Ecology 71(2):349-365. Its invasiveness is due primarily to its phenomenal growth rate: under optimum conditions it will double in size every 2-5 days and quickly cover the surface of slow moving bodies of water. Cytologia 31(3):330-338. Invasive Salvinia minima, a rapidly growing non-native aquatic plant, has been discovered in Alabama's Guntersville Lake on the Tennessee River.

Being a pentaploid species, S. molesta demonstrates irregularities during meiosis that prevent spore formation and result in functionally sterile plants (Loyal and Grewal 1966; Mitchell 1979). S. molesta has a high growth rate and three distinct growth stages. Gulf and Caribbean Research 22:63-66. Dallas, TX. Like dense floating mats of waterhyacinth, dense floating mats of S. molesta support secondary colonizing plants, leading to the formation of floating islands or tussocks (McFarland et al. Aulbach.
