  • Polyphenoloxidase activity (PPO) in the leaves of Erechitites hieracifolia was estimated by Warburg's manometric method. The emzyme was most reactive toward chlorogenic acid followed by caffeic acid. Diethyldithiocarbamate and potassium cyanide were shown powerful inhibition rate to the polyphenoloxidase from the leaves of Erechitites hieracifolia. We confirmed antioxidant activity of the leaves of Erechitites hieracifolia by DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging method. Electrophorectic isoenzyme banding patterns of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) were observed by native PAGE. The correlation of PPO and antioxidant enzymes is not investigated yet. That is need to further study.

  • This study was conducted to obtain the basic information on saline tolerance of plants. Fourteen plant species were grown under different salinity adjusted with NaCl. After 14 days treatment, physiological changes were investigated. Proline contents of tested plants were increased as salinity was increased. Acalvpha australis, Bidens bipinnata, Erechitites hieracifolia, Erigeron canadensis, Punicum dichotomiflorum, and Solanum nigrum showed drastic increase of proline contents in 200mM NaCl treatment. But Atriplex gmelini, Suaeda asparagoldes did not show drastic increase. As the NaCl concentration increased to 200mM in media, both contents of $Na^+$ and $Cl^-$ were increased. Acalypha australis, Digitaria sanguinalis, Erechitites hieracifolia, and Solanum nigrum showed drastic increase in $Na^+$ and $Cl^-$ contents under 200mM NaCl. But Suaeda asparagoides. Atriplex gmelini, and Spergularia marina were slightly increased. As salinity increased, the $K^+/Na^+$ ratio of halophytes, such as Suaeda asparagoides, Atriplex gmelini, and Spergularia marina were more slightly decreased than glycophytes.
