Leaf phenology, growth and photosynthesis in Pseudobombax munguba (Malvaceae)
Marenco, R. A.; Sousa, Francinete de Freitas; Oliveira, Marcilia Freitas deMunguba (Pseudobombax munguba) is a tree often found in low-land forests of the Amazon region, and there is a paucity of data regarding its ecophysiology. The aim of this work was to determine photosynthetic rates and growth of munguba saplings and to describe leaf phenology of a munguba tree. In greenhouse-grown saplings, diameter growth, leaf expansion, photosynthesis and stomatal conductance were determined....
Gas exchange, biomass allocation and water-use efficiency in response to elevat...
Oliveira, Marcilia Freitas de; Marenco, R. A.Prolonged droughts are predicted for some parts of the Amazon; however, it is still unclear how Amazonian trees will respond to water stress under the ongoing increase in CO 2 concentration. The aim of this study was to assess the effect of elevated CO 2 (eCO 2 ) and drought on photosynthetic rates, water-use efficiency, and biomass allocation in andiroba (Carapa surinamensis). The plants were grown in pots at ...
