The roots of Cichorium intybus L. (chicory) have many nutritional qualities and also have been used for health promotion as traditional medicine. The antimicrobial activity of Cichorium intybus L.'s (chicory) ethanol extract on Bacillus cereus ATCC 10876 were investigated using spot on lawn method in this study. Ethanol extract exhibited antimicrobial activities against Bacillus cereus ATCC 10876 with significance. Also, the results produced the larger zones of inhibition against Bacillus cereus ATCC 10876 tested, with increasing concentration of Cichorium intybus L.'s (chicory) ethanol extracts,. Hence, Cichorium intybus L. (chicory) could be served for keeping the safety of various dairy products as natural antimicrobial agents.

This study aimed to evaluate the growth of Cichorium intybus, Brassica juncea, and Lactuca sativa at varying seed ratios, and to suggest an efficient management plan for sustainable indoor agriculture systems. It was treated with mixed sowing as follows: 30 chicory seeds (chicory alone: CC), 22 chicory seeds + 8 lettuce seeds (C₃L₁), 20 chicory seeds + 10 lettuce seeds (C₂L₁), 15 chicory seeds + 15 lettuce seeds (C₁L₁) as intraspecies, and 30 mustard seeds (mustard alone: MC), 22 mustard seeds + 8 lettuce seeds (M₃L₁), 20 mustard seeds + 10 lettuce seeds (M₂L₁), 15 mustard seeds + 15 lettuce seeds (M₁L₁) as interspecies. The study identified the competitive response in seed germination between Cichorium intybus and Lactuca sativa, and in the C₃L₁ experimental group, Lactuca sativa had the highest leaf length, root length, chlorophyll content, and fresh weight. Therefore, the higher the ratio of Cichorium intybus, the higher the growth and productivity of Lactuca sativa; however, higher the ratio of Lactuca sativa, the lower the growth of Cichorium intybus. Furthermore, the nitrogen and potassium content in the substrate was the highest in the C₃L₁ experimental grorp which had the highest seeding rate of the Cichorium intybus. Comparing the groups Brassica juncea and Lactuca sativa, the higher the seeding ratio of Lactuca sativa, the higher the growth and productivity of Brassica juncea. Therefore, a companion seeding of Brassica juncea and Lactuca sativa is beneficial; this could be effective in having a high seeding ratio of Lactuca sativa.

질소 시비수준이 치커리의 3가지 품종에 있어 생육과 품질에 미치는 영향을 조사하고자 수행한 본 실험의 결과는 다음과 같다. 1. 30kgN/10a 처리구에서 외형적인 생육이 가장 좋았지만 잎끝마름과 추대 발생율은 20kgN/10a 처리구와 10kgN/10a 처리구에서 보다 낮았다. 2. 품종간 비교에서 ‘Winter’가 다른 품종에 비해 생육이 양호하였으나, 잎끝마름과 추대 발생율도 높았다. 3. Vitamin C 함량은 모든 품종에서 10kgN/10a 와 20kgN/10a 처리구가 30kgN/10a 에 비해 높았고, 품종에서는 ‘Winter’가 높은 수치를 나타내었다. 4. 건물중의 경우 각 품종 모두 30kgN/10a 처리구에서 가장 높게 나타났으나 건물율에 있어서는 20kgN/10a 처리구와 10kgN/10a 에서 높게 나타났다.

Continuation of a phytochemical study of Cichorium intybus L. (Astraceae) growing in Egypt, resulted in the isolation and identification of a new sesquiterpene lactone 3,4-dihydrolactucin, in addition to the eight known compounds; kaempferol, isoscutellarin, cichoriin, umbelliferone, lupeol, lupeol acetate, ${\beta}-sitosterol$, and ${\beta}-sitosterol-3-O-glucoside$. Chemical structures of the isolated compounds were assigned based on different physical, chemical, and spectroscopic techniques including IR, UV, MS, 1D- and 2D-NMR spectra. Furthermore, the antimicrobial, and spasmogenic activities of some fractions and isolates were also assessed.

Objective: Oxidative stress has been suggested as a possible mechanism for the adverse effects of heavy metal toxicity on male reproduction. Cichorium intybus L. is used in Iranian folk medicine as a hepatoprotective agent as well as for its supposed fertility-enhancing properties. The present study was performed to investigate whether the ethanolic extract of C. intybus leaves could protect male rats against lead-induced testicular oxidative stress. Methods: In this experimental study, adult Wistar rats were treated with 0.1% lead acetate in drinking water alone or with 50, 100, or 200 mg/kg body weight of C. intybus extract via gavage once daily for 70 days. The weight of their reproductive organs, levels of serum hormones, histometric parameters of the seminiferous tubules, epidydimal sperm quality, and oxidative stress status were evaluated. Results: The testis weight, seminiferous tubule diameter, epididymal sperm count, serum testosterone level, and testicular levels of superoxide dismutase and glutathione peroxidase were significantly reduced (p< 0.05) in the lead-treated rats. Moreover, significantly (p< 0.05) higher levels of malondialdehyde were observed in the lead-exposed group compared to the control. However, the co-administration of C. intybus ethanolic extract in lead-treated rats was associated with a significant improvement in reproductive parameters. Conclusion: We conclude that C. intybus leaf extract has the potential to prevent lead-induced testicular toxicity and to suppress the adverse effects of lead on male reproductive health.

치커리(Cichorium intybus L.)의 우량 종근 생산을 위한 휴면 특성을 구명하기 위해 시기별로 생육 특성과 ABA 함량을 조사하였다. $5^{\circ}C$ 이하의 저온누적시간은 10월 7일부터 12월 3일 조사까지는 서서히 증가하는 경향을 나타내었으나 이후 증가폭이 커졌다. 종근 무게는 10월 말부터 12월 3일 조사까지 큰 폭으로 증가하였으나, 이후부터 12월 17일 조사까지 거의 증가하지 않았다. 종근 내 ABA 함량은 10월 7일부터 12월 3일 조사까지 아주 낮은 수준으로 변화가 거의 없었으나, 이후 12월 10일 조사에서 급격히 증가하였고 2주후인 12월 24일 조사에서 급격히 감소하였다. 따라서 $5^{\circ}C$이하의 저온누적시간이 큰 폭으로 증가하고 종근 무게가 변화하지 않는 시기, 그리고 ABA 함량이 급격히 증가하는 시기를 고려하면, 치커리는 12월 3일 이후부터 대략 2주간 내재 휴면을 하고 이를 타파하기 위한 저온요구시간은 대략 240시간 정도로 생각된다.

The establishment of an efficient protocol for plant regeneration and micropropagation from leaf explant cultures of Chicory, Cichorium intybus L. var. sativus. is reported. Callus formation rate appeared 100% from explant in all growth regulators, but calli formed in the prensence of naphthaleneacetic acid (NAA) were appeared very compact and non-embryogenic state. The regenerated shoots were obtained from leaf explant cultures on solid MS medium containing different concentrations of cytokinins and auxin. The highest number of shoots (5.7) per explant and shoot growth (2.8cm) was obtained on MS medium containing 0.1 mg BAP L$^{-1}$ and 0.1 mg NAA L$^{-1}$ . Indole acetic acid was the most suitable auxin for root formation among three auxins tested. 2,4-D had no effect on shoot and root formation.
