This experiment was conducted to study the effect of intercropping system on the population of soil nematodes. The kinds of nematodes inhabitated in peony field were Meloidogyne sp., APhelenchoides sp., Ditylenchus sp., and Xiphinema sp., Meloidogyne sp., was dominant in the experiment field. The population of Meloidogyne sp., was fewer in the peony field intercropped with sesame and job's tear than intercropped with red pepper and Rehmannia glutinosa L. The occurence of powdery mildew was decreased in the peony field intercropped with red pepper and Job's tear.

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.

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 conducted to find to change of component by different species, plant parts and growth stage of Paeonia lactiflora Pallas Among the species of peony, the contents of compounds was higher in cultivated peony (P. lactiflora P.) as compared with wild peony (P. japonica M., P. obobata M., P. anomala L.). Amount of methyl gallate was highest in 0.45% at Euisung jakyak. Amount of compounds in peony was the highest in 1.0% at paeoniflorin, followed by methyl gallate, astragalin and kaempferol in order. Contents of compounds with different growth stage were observed highest in April, and showed decreased trend in the later growth stage. Methyl gallate was present in 1.79% at petal, 0.56% at leaf and 0.01% at root, astragalin present at 0.27% at petal, 0.20% at leaf and 0.03% at root, and paeoniflorin present at 0.43% at petal, 1.09% at leaf and 2.52% at root.

The aim of this study was to investigate the correlation between soil properties and marker compounds contents of Paeonia lactiflora. The methods of determining marker compounds were validated by measuring the linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy and recovery using UPLC analysis. P. lactiflora contained albiflorin at 0.04 ± 0.00 ~ 2.79 ± 0.21%, paeoniflorin at 1.98 ± 0.14 ~ 6.67 ± 0.84%. The root dry weight (RDW) of P. lactiflora was 0.06 ± 0.02 ~ 1.27 ± 0.28 kg. The soil properties analysis such as soil pH, electric conductivity (EC), organic matter (OM), total nitrogen (TN), available phosphate (Avail. P₂O₅), exchangeable cation and cation exchange capacity (CEC) were performed following standard analysis manual. The results of correlation analysis between soil properties and growth characteristics, available P₂O₅ was positively coreelated with the RDW of P. lactiflora. On the other hand, the RDW of P. lactiflora showed significantly negative correlation with contents of albiflorin and paeoniflorin. The results of this study was might be help to provide useful information on the establish of standard cultivation by the investigate correlation analysis between growth characteristics and marker compound contents of P. lactiflora.

To investigate identification of species distribution state, population density of plant parasitic nematodes and damaged state by parasitism of nematodes with soil samples taken from major cultivating area of medicinal herbs in Kyungbuk districts are summarized as follow; total species belonging to genera in families were identified from 43 different medicinal herbs. The dominant nematode species on medicinal herbs was Meloidogyne hapla by 55.6% of field infection. Damaged state by parasitizm of Root-knot nematode, M. hapla, M. incognita are severed 15 medical plant except P. japonica, infected field were in 54.5~88.0%, and highered in population densities of 2nd larvae, Gall, Egg sac. Percentage of yield-decrease were 57.8% in A. gigas, 49.1% in P.japonica. Lighten effect of M. spp. by cropping system were lowered in population density in Rice+Paeony than Paeony+Paeony in paddy field, and also lowered in Sesame+Paeony or one year fallowing after harvest Paeony than Red pepper+Pseony, Paeony+Paeony in upland field.

In peony fields located in Uisong and Yeongcheon distribution of Meloidogyne hapla was examined. Of 131 fields examined, M. hapla was isolated from 102 fields. In 57.8% of the infested fields, M. hapla density was higher 31 larvae1300 ml soil, the larval density isolated from upland fields were higher than those from paddy fields. Sandy loam soil harbored higher number of larvae than clay soil. Physio-chemical properties of soil might affect nematode population: High larval density was detected from those fields with low contents of OM, K+ and low pH. Fields infested with high larval densities required more lime than those with low or non infested fields.

This study was conducted to find out the effect of municipal sewage sludge application on the yield and the heavy metal content in Paeonia abliflora Pall root. When the municipal sewage sludge was applied to the soil, the yields and growth of Paeonia abliflora Pall increased, and the contents of T-N, P in soils increased, while there is no difference in contents of heavy metals and inorganic materials in roots. Therefore, it is apparent that the contents of heavy metals in roots of paeonia abliflora Pall would not due to increase with the municipal sewage sludge application.

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.
