title: [Resistant physiology of three mangrove species in a constructed wetland sewage treatment system].
abstract: This paper studied the resistant physiology of three mangrove species, Sonneratia caseolaris, Aegiceras corniculaturn and Bruguiera gymnorrhiza in a subsurface flow-constructed wetland sewage treatment system under freshwater condition. The results showed that in a year period, the superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) activities of three mangrove species increased gradually and maintained at a high level, the proline content reached the maximum from July to September, while the plasma membrane permeability did not show any obvious change. In comparing with those grown in the Futian Nature Reserve of Shenzhen, three mangrove species in the test sewage treatment system had lower SOD, POD and CAT activities and higher proline content, while no significant difference was observed in the malondialdehyde (MDA) content and plasma membrane permeability. It was suggested that three mangrove species could adapt to the subsurface flow-constructed wetland sewage treatment system under freshwater condition.
