Four urushiol components isolated from the sap of Korean lacquer tree(Rhus vernicifera Stokes) showed a strong antifungal activity, but they have no or low activity the bacteria and yeasts. Among them, 3-pentadecylcatechol marked the highest activity on the spore germination of Cladosporium herbarum (MIC:4μg/ml).

To study the effects of metal ions on the activity of anti-oxidase enzymes, the activity of superoxide dismutase (SOD) and peroxidase (POD) and isozyme patterns of Brassica juncea have been studied after treating with CD, Cu, Zn, and Al. The activity of SOD after treating with metal ions was higher than that of untreated control. SOD activity in leaves increased by treatment of 50 ppm of Zn and 500 ppm of Al. POD in stems gave highest activity after treating with 500 ppm of Cu. When the activity was compared by plant parts, lowest POD activity was observed in leaves in which protein content was higher than other tissues. When the activity was expressed as percentage of control, SOD activity was increased after treating with metal ions. SOD activity in leaves and roots of metal treated plant was significantly increased under the metal ions stress conditions. In the roots of 50 ppm of Zn treated plant, SOD activity was extremly high. POD activity was inhibited with Cd and Zn treatment in all parts of the plant. However, in leaves and stems, there was marked increase in activity after treating with Cu. The patterns of SOD isozyme after metal treatment show that two bands were stained in all metal ion treated and that no new band appeared. POD isozyme band intensity resulting from the treatment of metal ions was in order of roots > stems > leaves, but there was no significant difference.

Many higher fungi of ascomycetes were collected at Mt. Jiri National Park from May to October 1996. They were identified and according to the results, Orbilia, Pezicula, Creopus, and Lasiospheria were new genera to Korea. Dasyscyphus bicolor, Orbilia coccinella, Pezicula acercicla, Mollisia revincta, Hypocera citina, Creopus gelatinosus, Lasiospheria ovina, and Rosellinia thelena were newly to Korea.

This study was carried out to obtain basic envirinmental information of the native area and growth characteristics at different age of Dendropanax morbifera LEV. In the southern Korea. The Dendropanax morbifera LEV. Was grown naturally at Wando, Cheju(Mt. Halla), Yecheon(Kermoon island),Sinan(Hong isand), Jindo(Mt. Chermchill) and Haenam(Mt. Taeroon), all between 30 to 450m above the sea level. The soil characterisitics of the native area had a pH of 5.3 to 5.4 with 8.4 to 9.8% content of organic matter and 18.2 to 21.3% soil moisture. Flowering starting in the middle of July begun when the trees were 6 years old. Six year old trees are 129 cm in stem height, 34 mm in stem diameter,15.4 in number of leaves with petioles 12.9 cm long. Xylem sap can be obtained from over 10 year old trees that grew well and have over 10 cm stems in diameter.
