'Usul' is a traditional medicinal herb, which has anti-inflammatory activities is distributed in India, Nepal, China, Korea, Japan. Korea pharmacopeia listed 'Usul' as either a species of Achyranthes japonica (Miq.) Nakai or A. bidentata Blume. Recent taxonomic studies in China and Japan delimited these taxa as two varieties, A. bidentata Blume var. bidentata and var. japonica Miq. A multivariate morphometric study of Achyranthes bidentata complex was undertaken to assess the entities of taxa that usefully could be recognized. Five quantitative characters were reviewed and analyzed with 293 specimens from Korea. The univariate analysis of inflorescence length, interval between florets, angle between floret and floral axis indicated that ranges among all taxa were continuous. However, quantitative characters of membrane size and the number of hairs within 4 were useful to identify two varieties. In PCA, the first three principal components accounted for 89.4% of the total variance. PCA revealed that var. bidentata showed distinctions in morphological attributes from var. japonica entity. Therefore, continued recognition at the infraspecifc level for these taxa is supported.

SULNONGTANG is a kind of “goomkok”-korean typical soup made with beef, tone and organs, and is belived to be as a good source of portein and calcium, but there is no standard formulation for that. In order to set up the standard formulation of SULNONGTANG cooking method, I have performed a nutritional analysis of change in the components of SULNONGTANG, which contained the proximate composition, free amino acids, nucleotides, cholesterol, calium, phosphorus and iron. The conventional SULNONGTANG were cooked by conventional methods varing cooking time and ingredient. And also the current Market SULNONGTANG were cooked by the same methods for conventional SULNONGTANG and adding beef's head, hooves or knee tones. The result obtained in this study were as fallows: 1. In case of conventional SULNONGTANG, the most desirable cooking time was from 12 to 18 hours, the preparation method for group A was the best to maintain the optimal amount of nutrients and 5'-IMP. 2. In Market SULNONGTANG, nutritional contents were poorer than that of conventional SULNONGTANG. When the beef's head was added to the Market SULNONGTANG, nutritional status were more desirable than those added hooves or knee bones.

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.

To determine the optimum $\textrm{P}_2\textrm{O}_5$ rate for dry matter production of Achyranthes japonica Nakai a medicinal plant, in Jeju island, plants were grown in 2001 under ten fertilizer treatments comprising of two N (90, and 180kg/ha) and five $\textrm{P}_2\textrm{O}_5$ (0, 100, 200, 300, and 400 kg/ha) levels. Plant height leaf length and width, stem diameter, and main root length and diameter were not significantly affected by $\textrm{P}_2\textrm{O}_5$ rate while $\textrm{P}_2\textrm{O}_5$ fertilization of 100 kg/ha increased the number of branches, spikes, and roots per hill by 18,38 and 43%, respectively, compared with the unfertilized $\textrm{P}_2\textrm{O}_5$ treatment and decreased with further increases in $\textrm{P}_2\textrm{O}_5$ rate. The number of roots per hill was greatest with the application of 200kg $\textrm{P}_2\textrm{O}_5$. The highest utricle dry matter yield (2.92 t/ha) was obtained with the application of 100kg $\textrm{P}_2\textrm{O}_5$. However, as $\textrm{P}_2\textrm{O}_5$ rate increased from 0 to 100 and 200kg/ha, root dry matter yield increased from 2.36 to 3.55, and 3.80 t/ha, and then decreased to 3.14, and 2.86 t/ha at 300, and 400kg $\textrm{P}_2\textrm{O}_5$ rates, respectively. As $\textrm{P}_2\textrm{O}_5$ rate increased from 100 to 400 kg/ha, $\textrm{P}_2\textrm{O}_5$ recovery in aboveground parts decreased from 34.1 to 7.1%.

To determine the optimum N rate m Jeju island for utricle and root production of Achyranthes japonica Nakai, a medicinal plant, the plants were grown at two plant densities $(50\;and\;100\;hills/m^2$, two plants per hill; mall plots) at six N application rates (0, 6, 12, 18, 24, and 30 kg/10a; split plots) in 2001. There was no significant interaction between plant density and N application rate for all measured agronomic characters. Main root length and roots per hill were 5 and 52% greater, respectively, but N content of stover was lower under lower plant density compared to higher plant density. The other characters were not affected by plant density. N application rate did not significantly affect mall stem diameter, spikes per hill, spike length, utricles per spike, mall root length and diameter, and utricle N content. As N rate increased from 0 to 30 kg/10a, SPAD values and stover N content increased linearly from 35.0 to 40.5 and 1.09 to 1.38%, respectively, and plant height, branches per hill, stover, utricle and root dry matter yields, roots per hill, and top N yield increased quadratically. Spikes per hill were increased in a cubic manner with increased N application rates. N application rate for the maximum dry matter yield of utricle and root in A. japonica was estimated to be 21 kg N/10a.

Endophytic fungi were isolated from the roots of plants growing naturally on the island of Dokdo. Plant samples, such as Miscanthus sinensis, Achyranthus japonica and Echinochloa crusgali were isolated from Dongdo, and those such as Honkenya peploides and Artemsia koidzumii were isolated from Seodo. Twenty one strains of endophytic fungi were isolated from these plants. To identify the strains, PCR (polymerase chain reaction) amplification of the partial ITS (Internal Transcribed Spacer) regions was done with universal primers ITS-1 and ITS-4 to determine the nucleotide sequence of the ITS regions. Of the strains isolated from Miscanthus sinensis, 75% were Penicillium sp. and 25% were Aspergillus sp. Fifty five percent of strains isolated from Achyranthus japonica were Penicillium sp., 30% were Aspergillus sp. and 15% were Zygorhynchus sp. Strains isolated from Echinochloa crusgali were Penicillium sp. (50%), Aspergillus sp. (12%), Giberella sp. (13%), Talaromyces sp. (9%) and Umbelopsis sp. (8%). Of the strains isolated from Honkenya peploides, 76% were Penicillium sp. and 24% were Pestalotiopsis sp. Strains isolated from Artemisia koidzumii were Penicillium sp. (81%) and Mucor sp. (19%). As a result of bioassay, Ec-3-1 strain isolated from Echinochloa crusgalli showed plant growth-promotion activity. Of all the endophytic fungi isolated, Penicillium sp. was the most abundantly distributed fungal strain in all plants used in this study.

The allelochemicals from aqueous extracts of A. artemisiifolia var. elatior leaves and roots were analyzed and 60 compounds in the leaf and 53 compounds in the roots were inspected. The main compounds were acids,. especially phenolic acids and some non-acids. The total amount of compounds in the aqueous extracts of A. artemisiifolia var. elatior leaves was higher than in the roots. The aqueous extracts had much high inhibiting effects on the germination and seedling elongation of selected plants. In both cases, the inhibiting effects were very different with different selected plants and increased significantly as the concentration of aqueous extracts increased. Capsicum annum, Achyranthes japonica, and Oenothera odorta plants were suffered more significant inhibition effects than Raphnus sativus, Cucumis sativus, Brassica camperstris plants. Aqueous extracts from leaves had slightly higher inhibition effects than the aqueous extracts from the roots.
