  • 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.

  • In general, the root color of Codonopsis lanceolata is white, but red or blue-colored root is found at a low frequency in nature. Red or blue-colored roots have scarcity value, thus farmers wish to produce colored roots. The factors for determining the color of roots are unclear whether the color is controlled by genetically or simply by environmentally such as soil environment. Using in vitro culture system which is advantageous for setting of the same culture condition, we analyzed the physiological and morphological characteristics and genetic differences among red-, blue- and white lines of C. lanceolata. In the red colored roots, stems of in vitro cultured plantlet were colored in dark red pigment. Histological analysis revealed that the red pigment was accumulated in the outer cortex layer of the stem and determined as anthocyanin. Chlorophyll contents in red root lines were higher than those in white- and blue root lines. Plantlets from red roots were smaller in both shoot length and total leaf area than those from white- and blue roots. Genetic differences among the three different colored C. lanceolata were determined by RAPD (Randomly Amplified Polymorphic DNA) analysis. Each line of colored roots had clear DNA polymorphism. These results indicate that the occurrence of red- and blue colored roots in nature was determined by genetic factors rather than soil enviromental conditions.

  • Total 90 species of medicinal plants were surveyed to see if they have any suppressive effects on the dinsity of M hapla at the exhibition field in the Chinan medicinal herbs experiment station. In 70 species including Achyranthes japonica, root-knot and/or egg sac of M. hapla was not found and these plants were planted in C. lanceolata field to check the degree of M. hapla infection. In 26 species including A. japonica, M. hapla infection was not observed. Simultaneously, 30 species were planted in pots to find out degree of infection by M. hapla. Dianthus chinensis, Rudbeckia bicolor, Sedum kantschaticum, Ricinus communis, Anemarrhena asphodeloides, Malva verticillate, Chelidonium majus, Sesamum indicum, Agrimonia pilosa, Geum aleppicum, Sanguisorba officinalis and Scrophularia buergeriana were free from infection. While the number of galls and density of M. hapla in soil were higher to high innoculation density, and the growth of C. lanceolata was rower.
