  • Graft cultivation of Paeonia and Moutan was attempted to improve the harvest yields of medicinal parts of the plants. When Paeonia root was grafted with Moutan stem, the harvest yields of underground roots showed 35% increase, with Paeonia radix and Moutan cortex ratio of 3 : 1 paeoniflorin and paeonol contents among grafted Paeonia radix (11.71 and 0.35 mg/g, respectively), Paeonia radix (9.91 and 0.80 mg/g, respectively), and Moutan cortex (10.81 and 2.84 mg/g, respectively) were not significantly different. Paeonia radix grafted with Moutan stem was cultivated to investigate the ecological properties and to compare index components, including minerals, fatty acids, and organic acids. The contents of 10 major minerals among the samples were very similar, whereas those of Fe were different, showing 86.06, 127.36, 75.05, and 140.63 mg/g for (Paeonia radix, Paeonia radix grafted, Moutan cortex, and Moutan cortex grafted) contents and GC profiles of 11 fatty acids including linoleic, palmitic, linolenic, and oleic acids and those of 6 organic acids including oxalic, citric, and malic acids were very similar. Results of sensory evaluations were very similar between Paeonia radix and Paeonia radix grafted or Moutan cortex and Moutan cortex grafted showed astringent taste, and stronger sensory intensity of Paeonia radix than Paeonia radix grafted showed bitter taste, and stronger sensory intensity of Moutan cortex than Moutan cortex grafted.

  • This study was carried out to screen 11 peony varieties collected for resistance to northern root-knot nematode, Meloidogyne hapla. The larval population of Meloidogyne halpa to the Uisongjakyak, Taebaekjakyak, Doseo, EP368, EP512 peony were detected high denisties with individuals of 98-173 per 300 ml soil, but Sabeol, Yongsu, Kimchon, Pl23 peony showed low number of larvar with 21-60. The root rot were lowered in Yongsu, Kimchon peony than Uisongjakyak, Taebaekjakyak, EP368, EP512. It seems to involved with densities of 2nd juvernile population in that rot rate of root was increased as increase of 2nd stage larvae. Two peony, Uisongjakyak, Taebaekjakyak were susceptable to M. hapla with high egg mass formation which showed 49,28 in each root. And Yongsu, Doseo, EP368, EP512 were Mid resistance with 1-15 egg mass of each root. Whereas Sabeol, Kimchon, Pl23, EP337, EP425 were found to be resistant to M, hapla with few egg mass formation of 4-7 each root.

  • This study was carried out to select proper intercrops in peony cultivation because peo­ny is damaged easily by disease and cannot make proper income with it's single crop system, so it needs rational intercropping system to raise it's productivity and income. The results of this study are as follows. The kinds of soil nematodes were Meloidogyne sp, Pratyienchus sp, Aphelenchoides sp, Ditylenchus sp, Xiphinema sp, and damaging dominant nematode was Meloidogyne sp. The density of Meloidogyne sp wa suppressed remarkably in the combination of peony+sesame, and peony + job's tears. This study shows that sesame and job's tear were most resistant crops to the IvIeloi­dogyne sp. The quanity of herbaceous peony was the best in the combination of peony+red pepper. The results of income analysis per lOa for three years shows next conclusion. Peony+red pepper combination and peony+ sesame combination were most effective when it's compared with single cropping of peony (1,490 thousand won). But red pepper was damaged easily by soil nematode, therefore, sesame was the most stable and high yield crop as a intercrop in the cultivation of herbaceous peony.

  • Comparative analysis of paeoniflorin, albiflorin and phenolic compound contents as bioactive components of peony was performed by Reverse Phase-High Performance Liquid Chromatography (RPHPLC) using the four- year-old peony which were different plant parts and pretreatment, such as removing or unremoving the cork layer of peony root before drying. The contents of paeoniflorin, albiflorin, (+)-taxifolin $3-O-{\beta}-D-glucopyranoside$, (+)-catechin and (-)-epicatechin were the highest in rhizome part, but those of gallic acid and benzoic acid in the leaves were higher than other parts. The contents of albiflorin, gallic acid, benzoic acid and (-)-epicatechin in the cork layer were higher than in those of the core, but the contents of paeoniflorin, (+)-taxifolin $3-O-{\beta}-D-glucopyranoside$ and (+)-catechin in the core were higher than those in the cork layer. In general, the rhizome part of peony root has been used only propagation purpose, but this part contained high contents of bioactive component. Therefore, it is needed that medicinal application of rhizome part in peony root was firmly investigated. Also, In the use of peony root for medicinal purpose, the use of peony root with cork layer can be efficient way on the practical use of useful components and the reduction of labor for removing the cork layer.

  • Peony is commonly used as roots that peeled and dried. But intact root contains higher medicinal constituents than peeled root (machine peeling). The yield of roots was also higher in intact roots. Use of intact root saved the labor time for peeling and 15% of root from yield loss by peeling. Paeoniflorin content was different with each zones of root. The content of Paeoniflorin was 5.11% in epidermis and 3.28% in cortex. When peeled peony roots were dried at hot air after briquet fire drying, root color was good for commercialization. But color of intact root was good at hot air drying without briquet fire drying. The required time for drying was longer in drying of intact roots than peeled roots drying.
