Adaptações de plantas submersas à absorção do carbono inorgânico

Abstract: RESUMO -(Adaptações de plantas submersas à absorção do carbono inorgânico). No presente trabalho são discutidos alguns aspectos teóricos dos mecanismos e adaptações empregados pela vegetação submersa para maximizar o aproveitamento do carbono inorgânico na água. O tipo de estratégia utilizada pelas macrófitas aquáticas submersas deve-se a diferenças genéticas entre as espécies e também às condições ambientais predominantes. Vários mecanismos fisiológicos e morfológicos, como a utilização do metabolismo C4, do … Show more

“…According to Pierini and Thomaz (2004), aquatic plants that perform metabolism C 3 can indeterminately refrain from performing it due to variations in photorespiration. Keeley and Sandquist (1992) state that certain plants can replace metabolism C 3 by C 4 to soften these effects.…”

“…The aquatic macrophytes present wide physiological and morphological plasticity, making them capable to colonize diverse habitats with a variety of physical and chemical characteristics (Pierini & Thomaz 2004). Growth and expansion of these plants in floodable and permanently flooded areas can culminate in the formation of wide green floating mats rich in organic matter originated from their decomposition and its buildup starts the formation of a floating island (Neiff 1982), regionally known as baceiro (Pott & Pott 2000), a floating meadow.…”

“…More competitive macrophytes, for example, exhibit higher leaf production and increased root porosity. These modifications are related to a better use of atmospheric resources and gas diffusion throughout the plant (Insausti et al, 2001;Pierini and Thomaz, 2004).…”
