salvinia minima growth rate

Salvinia minima produces excessive surface growth, which can impede waterways and restrict boating. Nature 320(6063):581-584. University of South Florida, Institute for Systemic Botany. Four hairs are joined at the tips and resemble a wisk. Proceedings of the Indian Academy of Sciences, Plant Sciences 89(3):161-168. Reproduction occurs mainly from fragmentation. It is usually referred to as common salvinia or water spangles. 2008 (April 9). Hydrilla eradication program annual report 2004 - Appendix II. During early colonization small leafed, thin plants lie flat on the water surface. During earlier stages of colonization S. minima demonstrates exponential growth rates. In lakes and large water-bodies upright well buoyed leaves are effectively dispersed by wind and currents to infest new coves. In Experiment 1, the starting population of 24 had a slower rate of increase than the starting population of 12.

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. The Times, Shreveport, LA. Growth rates for Salvinia molesta from Lake Kariba have been calculated in axenic laboratory cultures and compared with those of S. minima by Gaudet (1973). 1966. 2000. In Experiment 2, the growth of the Salvinia minimaplants with the addition of phosphorous was slightly faster than the growth of the plants without the nutrient. The leaves are attached to an elongated rhizome. Temperatures lethal to Salvinia molesta Mitchell.
