Abstract:
Taking Sansevieria trifasciatavar ‘Laurentii’ as test material,through the fumigation test,the effects on activities of superoxide dismutase (SOD),peroxidase (POD) and catalase (CAT),as well as the contents of chlorophyll (Chl),superoxide radical (O·2),malondialdehyde (MDA) and proline (Pro) in Sansevieria trifasciatavar ‘Laurentii’ under the combined stress of benzene and formaldehyde were studied.The results showed that as the benzene and formaldehyde concentration increasing,the photosynthesis was limited,the chlorophyll content decreased while the contents of superoxide radical(O·2),malondialdehyde (MDA) increased.Meanwhile,the activities of superoxide dismutase (SOD) and peroxidase (POD) increased while catalase (CAT) activity reduced.Generally speaking,the change of superoxide dismutase (SOD),peroxidase (POD) and catalase (CAT) under benzene and formaldehyde combined stress was a complicated interaction.
