| Abstract/Contents: | "A pot experiment was conducted to study the effects of the combined cadmium and lead stress on physiological characters of Kentucky bluegrass seedlings. The results showed that the Cd2+ stress had significant (P<0.05) effects on the indices including leaf cell membrane permeability, malonaldehyde (MDA) content, chlorophyll content and proline content. leaf cell membrane permeability, MDA and proline content of seedling with 80 mg · kg-1 Cd2+ treatment were significantly (P<0.05) higher than those of seedling with 40 mg·kg-1 Cd2+ treatment whereas the chlorophyll content result was reverse. The Pb2+ stress had significant (P<0.05) effects on proline content, leaf cell membrane permeability after 10 d and 20 d treatments and MDA content after 20 d and 30 d treatments. Leaf cell membrane permeability, MDA and proline content of seedling with 1 000 mg · kg-1 Pb2+ treatment were significantly (P<0.05) higher than those of seedling with 600 mg · kg-1 Pb2+ treatment. The significant interaction of Cd2+ and Pb2+ stress was observed in MDA content after 30 d treatment and proline content after 20 d and 30 d treatments. With the extension of heavy metals stress time, chlorophyll content firstly increased and then decreased, leaf cell membrane permeability, MDA and proline content increased gradually." |
