Dianthus chinensis L. is a very ornamental plant and widely used in landscaping. It can be tolerant to
some level of salt stress. In order to study H2O2 distribution and activities of antioxidant enzymes under salt stress,
seeds of Dianthus chinensis L. were treated with different NaCl concentrations. The results suggested that H2O2
initially produced in root and then transferred to leaf via stem xylem and leaf vein during seed germination under
long-term salt stress. Same phenomena were observed in seedlings under short-term salt stress. However, the
distribution varied with time under different NaCl. H2O2 was quickly scavenged with 100 mM NaCl. POD and CAT
obviously dropped, as well as SOD significantly rose under NaCl. In the meantime, APX and GR seemed to be no
associated with salt stress.
Key words: Antioxidant enzymes , Dianthus chinensis L., H2O2 balance, H2O2 distribution, salt stress, ,
