The present study was carried out to clarify the chromosome numbers and karyotype of Atractylodes japonica Koidz. ex Kitam. and A. macrocephala Koidz.. The somatic chromosome numbers of two species were same; basic chromosome number x=12, and somatic chromosome numbers 2n=24. The present result of A. japonica Koidz. ex Kitam. was same to previously reports and that of A. macrocephala Koidz. was reported first in this study. Size and shape of chromosome were some different from A. japonica Koidz. ex Kitam. and A. macrocephala Koidz.. The karyotype of A. japonica Koidz. ex Kitam. was described as follows; 2n : 24 : 8L + 14M +2S : 2 $A^{sm}$ +2 $B^{m}$ +2 $C^{m}$ +2 $D^{st}$ + 2 $E^{m}$ +2 $F^{m}$ +2 $G^{m}$ +2 $H^{sm}$ + 2 $I^{m}$ + 2 $J^{m}$ + 2 $K^{m}$ + 2 $L^{m}$ . And the karyotype of A. macrocephata Koidz. was described as follows; 2n : 24 : 10L +12M +25 : 2 $A^{m}$ +2 $B^{sm}$ +2 $C^{sm}$ +2 $D^{sm}$ +2 $E^{sm}$ +2 $E^{sm}$ +2 $G^{sm}$ +2 $H^{m}$ +2 $I^{m}$ 2 $J^{m}$ +2 $K^{m}$ +2 $L^{m}$ . .

This study was carried out to evaluate cytotoxic effects of Atractylodes macrocephala Koidz. (A. macrocephala Koidz.) extract on NIH 3T3 fibloblast. SK-MEL-3 (HBT 69) and KB (ATCC No, OCL 17) cell lines. Disruptions in cell organelles were determined by 3-(4,5-dimethylthiazol-2-y1)-2,5-diphenyl-2H-tetrazoliumbromide (MTT) assay. 10.2 mg/ml Concentration of A. macrocephala Koidz. extracts in SK-MEL-3 showed that their susceptibility (sensitivity) to these compounds decreased in the following order ; adriamycin > H₂O > ethyl acetate > ethyl alcohol > chloroform > n-hexane in SK-MEL-3 cell lines ; 5-FU > H₂O > n-hexane > ethyl acetate > ethyl alcohol > chloroform in KB cell lines. In order to develop an antimicrobial agent, A. macrocephala Koidz. was extracted with solvents. The minimal inhibitory concentrations (MICs) of each solvent extract of A. macrocephala Koidz. against microogranisms were also examined. Antimicrobial activities of ampicillin and ketoconazole as references were compared to those of each solvent extract of A. macrocephala Koidz. The antimicrobial activity of the ethyl acetate soluble extract of A. macrocephala Koidz. had growth inhibition activity against S. mutans and P. putida (MICs. 500 ㎍/ml). These results suggest that the ethyl acetate soluble extract of A. macrocephala Koidz. possessed antitumorous and antimicrobial agents

삽주(Atractylodes japonica Koidz. ex Kitam.)와 큰꽃삽주(A. macrocephala Koida.)의 근경 과 측근, 줄기, 잎과 엽병, 자방, 잎의 표피 세포의 형태와 크기에 관한 해부학적형질을 조사하여 이들의 분류학적 가치를 평가하고자 본 연구를 수행하였다. 줄기와 자방의 횡단면 구조는 매우 유사하여 두 종이 구분되지 않았으나, 근경에 분포하는 유관의 크기와 단위면적 당 분포수, 잎과 엽병의 횡단면 형태, 잎 표피 세포의 크기와 기공의 단위 면적당 분포수에서 차이가 있어 두 종을 구별하는 형질로서 가치가 있는 것으로 생각되었다.

Background: In September 2017, wilting and rhizome rot symptoms were observed on Atractylodes macrocephala Koidz. in Jecheon-si and Eumseong-gun. This study was carried out to isolate hitherto unidentified pathogenic fungi from A. macrocephala and to test the pathogenicity of isolated fungi against Atractylodes spp. genus such as A. macrocephala, A. japonica, and their interspecific hybrids. Methods and Results: The diseased plants were washed with running tap water, and the boundary between the healthy area and the diseased area was cut while the pathogens were isolated by growing cultures from the diseased areas on Phytophthora semi-selective medium. The internal transcribed spacer (ITS) region of the isolates was used in this study for identification. Test plants were cultivated in the glasshouse at 20℃ - 30℃ for 4 months and then used for pathogenicity test. The pots with plants inoculated with mycelial plugs and zoospores were placed at 25℃ for 48 h in a dew chamber where relative humidity was above 95%, and then moved into the glasshouse at 20℃ - 30℃. The presence or absence of pathogenicity of the strains was determined by evaluating the symptom of plant wilting. The inoculation test was performed in three replicates with a non-treated control. Conclusions: On the basis of results of ITS sequence analysis, the strains isolated from the diseased plants was identified as Phytophthora sansomeana. Biological assay using test plants confirmed the pathogenicity of P. sansomeana against Atractylodes macrocephala. This is the first report of rhizome rot in A. macrocephala caused by P. sansomeana.

최근 중국에서 도입되어 경북 북부지방을 중심으로 재배면적이 확대되고 있는 백출의 재배기술확립 시험의 일환으로 화기제거가 생육과 수량에 미치는 영향을 구명하기 위하여 시험 수행 한 결과를 요약하면 다음과 같다. 1. 백출의 화기제거에 따른 지상부 생육은 무제거에 비해 화기제거에서 초장은 1.7∼2.5cm정도 화기가 제거된 만큼 짧았으며 엽의 크기, 경수와 경직경은 차이가 없었으나 지상부 생체중은 48∼60% 감소되었다. 2. 백출의 화기제거시기별 화기생체중은 화기제거시기가 늦어질수록 무거워져 개화직후에는 주당 39g으로 지상부 생 체 중의 60%를 차지 하였다. 3. 화기제거에 따른 지하부 생육은 무제거에 비해 화뢰출현기제거(7월 15일)와 개화전제거(8월 20일)에서 근경장, 근경직경 등이 컷으며 건근경수량도 유의하게 증수되었는데 화뢰출현기제거구는 290.5kg/10a으로 무제거구보다 40% 증수되어 가장 많았다. 4. 정유함량은 무제거구 0.71m1/50g에 비해 화뢰출현기제거는 12% 개화전 제거는 9%증가한 것으로 나타났으나 개화후 제거는 차이가 없었다.

This study was carried out to compare chromosomal characteristics between Atractylodes japonica and A macrocephala. Cytogenetic analysis was conducted based on karyotype analysis and physical mapping using fluorescence in situ hybridization. As a result of karyotype analysis by feulgen staining, somatic chromosome numbers of A. japonica and A. macrocephala were 2n=24. The length. of the mitotic metaphase chromosomes of A. japonica ranged from $0.70\;to\;1.60{\mu}m$ with a total length. of $12.11{\mu}m$ and the homologous chromosome complement comprised six metacentrics, five submetacentrics and one subtelocentrics. On the other hand, the length of the mitotic metaphase chromosomes of A. macrocephala ranged from $0.90\;to\;2.35{\mu}m$ with a total length of $16.58{\mu}m$ and the homologous chromosome complement comprised seven metacentrics and five submetacentrics. The total length of A. japonica chromosomes was shorter than that of A. macrocephala, but A. japonica had one subtelocentrics (chromosomes 4) different from A. macrocepha1a. chromosomes. The F1SH technique using 17S and 5S rDNA was applied to metaphase chromosomes. The signals for 17S rDNA were detected on the telomeric regions of chromosomes 4 and 5 in both A japonica and A. macrocephala. The 5S rDNA signal was found in the short arm of chromosome 1.

Two Atractylodes species, A. japonica Koidz. ex Kitam. (AJ) and A. macrocephala Koidz (AM) were used in this study. AJ population had higher amounts of Sesquiterpenoids and stronger tolerance to root rot but less vigor of root growth than AM population. Two populations (AJ and AM) were crossed to make interspecific hybrid population. A total of 98 lines propagated clonally were selected from a cross of AJ and AM, and evaluated for contents of sesquiterpenoids, atractylon (ATLN) and atractylenolide III (AT3) using high performance liquid chromatography (HPLC), and growth characters such as plant height, stem number and root weight. HPLC profiles of the hybrids were compared with those of parent plants, and it demonstrated the production of introgression hybrid by crossing between AJ and AM. Of 98 clonal lines,10 lines were selected by 10% level based on the growth vigor and tolerance to root rot, and AJM2102-51 line showed the heaviest root weight (117.1 g/plant) among them. A total of 98 hybrid lines contained on average $0.16\;{\pm}\;0.10\;mg/g$ of $AT3,\;2.00\;{\pm}\;1.37\;mg/g$ of ATLN, and $2.16\;{\pm}\;1.40\;mg/g$ of total sesquiterpenoids, showing high coefficients of variation (above 65%). Ten lines having high contents of sesquiterpenoids were selected, and AJM2101-15 had the highest amount (9.83 mg/g) of ATLN, and showed 40.8 g/plant of root weight similar to mean value (39.9 g/plant) of hybrid lines. The result showed that the introgression of both characters of vigorous growth from AM and high sesquiterpenoids content from AJ could be possible to make new hybrid lines by crossing between AJ and AM.
