| Abstract/Contents: | "To investigate the physiological response and ion absorption of Poa pratensis to cadmium (Cd) stress, seedlings were raised by sand culture method, and plant height, root length, leaf and root fresh weight, photosynthetic indexes, antioxidant enzyme activities, leaf hormone levels and ion content of Poa pratensis under different concentrations of Cd stress were measured. The results showed that Cd stress inhibited the growth of Kentucky bluegrass, caused wilting and chlorosis, significantly reduced the contents of photosynthetic pigment, inhibited leaf transpiration rate, stomatal conductance, net photosynthetic rate and intercellular carbon dioxide concentration. The results also demonstrated tha with the increase of Cd stress concentration, the activities of CAT and POD in leaves decreased gradually, while the activities of CAT and POD in roots increased. In addition, Cd stress decreased the IAA and GA3 contents and increased the ZT contents in leaves of Poa pratensis. Moreover, Most Cd was enriched in the root and less transferred to the leaves. Further, Cd stress resulted in decreased Zn2+ content, increased Mg2+ content in leaves, and decreased Mg2+ content in roots. In conclusion, cd stress inhibit the growth, development, photosynthesis and ion absorption of Kentucky bluegrass, and Cd toxicity could be alleviated by regulating antioxidant enzyme activity and hormone level. The results of this study are expected to provide a theoretical basis for the treatment of Cd-contaminated soil." |
