| Abstract | The oxidative stress caused by the production of reactive oxygen species (ROS) is one of the responses that plants exhibit facing environmental stress. Our objective was to evaluate the oxidative stress of the aquatic macrophytes Crinum americanum and Spartina alterniflora under two conditions: salinity and nutrients that occur in the estuary of the Itanhaém river (SP). Roots and leaves (5 plants) of C. americanum were collected in each area (5 samples / area). The plant material for analysis of chlorophyll (a + b), carotenoids, H2O2, MDA and antioxidant enzymes SOD and CAT with platform in N2 without field and liquid in freezer at -80 ° C. Vegetable material was also collected in each replicate to evaluate the total N and P content of the plant and of the sediment. The data were submitted to Analysis of Variance (ANOVA) and compared by the Tukey test (p <0.05). The results showed that: C. americanum and S. alterniflora suffered higher oxidative stress in upper and middle estuary, respectively; The State of São Paulo changes have suffered greater stress in the area of sewage |
