Effects of light on the growth and photosynthesis of Egeria najas planchon

Brazilian Archives of Biology and Technology, 2003
Photosynthesis and growth of Egeria najas (Hydrocharitaceae) from a subtropical reservoir (Itaipu Reservoir, Brazil-Paraguay) were measured in response to low light intensities (0-124 µM m-2 s-1 PAR) in the laboratory.

Inorganic carbon shortage may limit the development of submersed macrophytes in habitats of the Paraná River basin Baixas concentrações de carbono inorgânico podem limitar o desenvolvimento de macrófitas submersas em habitats do alto rio Paraná

Acta Limnologica Brasiliensia, 2011
AIM: In this investigation we carried out an experiment to assess whether the growth of Egeria najas and E. densa (two rooted submersed Hydrocharitacea, native to South America) are limited by inorganic carbon or not; METHODS: We measured the early plant

Origin and Early Evolution of Hydrocharitaceae and the Ancestral Role of Stratiotes [PDF]

The combined morphological features of Stratiotes (Hydrocharitaceae) pollen, observed with light and electron microscopy, make it unique among all angiosperm pollen types and easy to identify.

Emissions of methane and carbon dioxide during anaerobic decomposition of aquatic macrophytes from a tropical lagoon (São Paulo, Brazil) Emissões de metano e dióxido de carbono da decomposição de macrófitas aquáticas de uma lagoa tropical (São Paulo, Brasil)

Acta Limnologica Brasiliensia, 2010
AIM: Massive accumulations of aquatic sedimentary plant are the main source of CH4 and CO2 emissions in floodplain lakes. To examine this connection, this study measured CO2 and CH4 formation during anaerobic decomposition of aquatic macrophytes from a ...
