  • Platycodon grandiflorum and Codonopsis lanceolata have been considered as cash vegetables and alternative medicine plants in Korea. In a previous survey from 1998 to 2010, repeated cultivation of the plant increased root rot disease incidence and severity. The disease has been recognized as critically limiting factor for crop production. However, control method has not been established for the disease of P. grandiflorum and C. lanceolata. In this study, control efficacy of Tebuconazole EC, Trifloxystroim SC and grapefriut extract was evaluated on the root rot disease of these plants in two different field conditions. Three of different fungicide were non critical effect to the disease severity and the control value, but grapefriut seed extract (GSE) was more ability to control the disease in C. lanceolata. In most things, soil drainage was the most important to decrease the disease severity and to improve the control value.

  • This study was carried out in order to investigate the functional properties of methanol extracts from two parts (root and fruit) of Xanthium strumarium by means of measuring the contents of total polyphenols and flavonoid as well as determining $ABTS{\cdot}^+$, DPPH radical scavenging activity, hydroxyl radical scavenging activity (OH${\cdot}$) and anticancer activity. The examination of physiologically active substances in the two parts revealed that the Xanthium strumarium fruit had high total polyphenol, flavonoid contents, $ABTS{\cdot}^+$ DPPH and hydroxyl radical scavenging activity. The Xanthium strumarium fruit has higher activities of anticancer activities on prostate cell lines compared to other cancer cell lines.

  • For the effective utilization of Wild Korean lettuce(Youngia sonchifolia Max.), the chemical characteristics, contents of free sugar, amino acid composition, fatty acid composition and minerals were analysed. Free sugars determined from the roots were rhamnose, fructose, glucose, sucrose maltose, melibiose and raffinose, whereas raffinose was not detected from the leaves. Of amino acid composition in the roots glutamic acid content was largest followed by histidine aspartic acid, leucine and proline. As for leaves glutamic acid was highest fellowed by aspartic acid, leucine and histidine. Mtehionine and cystine were found in low content in both roots and leaves. Major fatty acid composition in total lipid(free and bound) were linoleic, linolenic and palmitic acid in both and leaves. P, K and Ca were rich minerals contained in the roots and leaves of Wild Youngia sonchifolia Max.

  • This experiment was carried out to know the effects of aerial part cutting on the growth and root yield of Achyranthes japonica. The various cutting treatments were tested. Cutting treaments were 20cm and 30cm cutting from the apical part of plant, when plant height was 30cm and 50cm, respectively. The seed amount was the largest at non-cutting, indication that cutting treatment inhibits fruiting. The most effective treatment for the root growth was 30cm cutting just before flowering time. Cutting just before flowering time increased root diameter, length and root weight comparing with non-cutting.

  • The COD removal capacity of aquatic plants, when foamed glasses were not used, showed 56% for Pistia straiotes, 48% for Phragmites japonica and 41% for Oenanthe javanica, but no significant COD removal was observed for Lythrum anceps. When the foamed glasses were used as support materials, the COD removal efficiency increased for all aquatic plants used in this study showing 69% fur Pistia straiotes, 68% for Pharagmites japonica 62% for Oenanthe javanica, respectively. The T-N removal efficiency of aquatic plants when foamed glasses were used as support materials showed 91% for Lythrum anceps and 93% for Phragmites japonica. Similar removal efficiency was observed as 94% for all aquatic plants planted as a group used in this study. The T-P removal efficiency of aquatic plants when foamed glasses were not used showed 35% for Lythrum anceps, 8% for Phragmites japonica, however, that, when foamed glasses were used, ranged 78% for Lythrum anceps, 43% for Phragmites japonica, showing that the foamed glasses increase the T-P removal efficiency of aquatic plants used in this study.
