Table 1.
Mean values (± standard deviation) of the chlorophyll a fluorescence performed during the day (8h and 12h) for the species M. obtusifolia, M. subsericea and I. laurina in restinga and forest. The following variables were obtained: quantum yield of PSII (YII) and maximum quantum yield of PSII (Fv/Fm). Different letters indicate significant differences to ecosystems. Lowercase letters indicate differences between hours while uppercase letters indicate significant difference between sites. (Tukey p≤0.05).
