Abstract:
|
Dianthus Chinensis L. is a salt-tolerant ornamental plant. Root is the first and critical part of plant to encounter soli salinity. In order to elucidate H2O2 impact on root morphology and mitochondrial permeability transition as well as activities of antioxidant enzymes in root ofDianthus Chinensis L., we treated seedling with H2O2 and DMTU under NaCl. The results revealed that change of H2O2 level under NaCl would negatively influence the root growth, as well as lower the value of mitochodrial membrane absorbance at 540 nm and the ratio of Cyt c/a. Meanwhile, SOD and POD under NaCl plus H2O2 and NaCl plus DMTU were far lower than those under NaCl alone.
Key words: Dianthus Chinensis L. , H2O2, mitochondrial membrane, root morphology, salt stress, ,
