Abstract: Aquatic plants can use differential allocation (trade-off) of carbon among their structures depending on the nutrition concentration. Given that N and P are limiting in the growth of plants, our questions were: Are the N and P concentrations in S. auriculata related to the biomass allocation to its structures? Is a differential allocation of N and P between floating and submerged leaves? We evaluated the relation between the nutrients and the biomass allocation, and the trade-off among the leaves using the Spe… Show more

“…In freshwater or continental ecosystems, macrophytes have favorable characteristics for their use as potential agents of remediation or as bio-indicators of environmental impact (França et al, 2014;Maroneze et al, 2014;Rocha et al, 2012), such as their wide distribution, performance in the food chain, natural filtering of pollutants and nutrient cycling of these environments (Esteves, 1998;Medeiros et al, 2016). They may present fixed and free floating biological forms, submerged fixed and free, emerging, amphibious or epiphytes (e.g.…”

“…Biomass productivity of aquatic macrophytes is related with their capacity to absorb NO 3 and/or PO 4 , transforming them in organic compounds (Camargo et al, 2003;Henry-Silva et al, 2008;Bottino et al, 2013). Species of the genera Pistia, Salvinia or Eichhornia present high stocks of N or P in their tissues (Martins et al, 2003;Camargo, 2000, 2006), moreover when submitted to an environment of reduced WLF (Neiff et al, 2008;Medeiros et al, 2016). Water temperature is also a variable directly related with the production of aquatic plant organic matter (Bottino et al, 2013).…”

“…Nitrogen is a limiting factor for crop growth and yield, since it is essential and required in large quantities by most plants (McAllister et al, 2012;Medeiros et al, 2016). Nitrogen nutrition in adequate quantities becomes essential for normal plant growth and satisfactory production.…”
