Chlorophyll fluorescence varies more across seasons than leaf water potential in drought-prone plants Anais da ABC (AABC)
ROSADO,BRUNO H.P.; MATTOS,EDUARDO A. DE.
ABSTRACT Among the effects of environmental change, the intensification of drought events is noteworthy, and tropical vegetation is predicted to be highly vulnerable to it. However, it is not clear how tropical plants in drought-prone habitats will respond to this change. In a coastal sandy plain environment, we evaluated the response of six plant species to water deficits across seasons, the relationship between their morpho-physiological traits, and which traits would be the best descriptors of plants' response to drought. Regardless of leaf succulence and phenology, responses between seasons were most strongly related to chlorophyll fluorescence. In this study we have demonstrated that a better comprehension of how tropical species from drought-prone...

Are leaf physiological traits related to leaf water isotopic enrichment in restinga woody species? Anais da ABC (AABC)
ROSADO,BRUNO H.P.; MATTOS,EDUARDO A. DE; STERNBERG,LEONEL DA S.L..
During plant-transpiration, water molecules having the lighter stable isotopes of oxygen and hydrogen evaporate and diffuse at a faster rate through the stomata than molecules having the heavier isotopes, which cause isotopic enrichment of leaf water. Although previous models have assumed that leaf water is well-mixed and isotopically uniform, non-uniform stomatal closure, promoting different enrichments between cells, and different pools of water within leaves, due to morpho-physiological traits, might lead to inaccuracies in isotopic models predicting leaf water enrichment. We evaluate the role of leaf morpho-physiological traits on leaf water isotopic enrichment in woody species occurring in a coastal vegetation of Brazil known asrestinga. Hydrogen and...
