A new asiatic lily cultivar 'Point' was derived from a cross between $Lilium$ $concolor$ var. $partheneion$ and 97-5 with orange colored petals made in 2000. The selection and the survey for the flower characteristics were conducted from 2005 to 2008 by using vinyl tunnels and greenhouse at Highland Agriculture Research Center, NICS, RDA. Based on flower color, 'Point' cultivar belongs to orange red group (O-R N30C). There was lots of spots in petal. The flowers had brown stigma and dark brown pollen. The stem color was dark purple. The flowering date was July 8. The plant height was 88.2 cm and flower numbers were 5.4 ea. The length and width of petal were 6.3 cm and 3.2 cm, respectively. The flower size was smaller than that of 'Prato' cultivar. The number of leaves was 12.2 ea. The length and width of leaves were 9.2 cm and 1.1 cm, respectively. The weight and circumference of bulb were about 24.6 g and 11.6 cm, respectively. 'Point' cultivar had resistance to bulb rot disease. The flowering duration was 16.1 days. The preference was good to 4.1 on 5 grades. 'Point' cultivar was registered as a new variety with No. 3446 in Korea Seed and Variety Service on April 2011.

This study was carried out to develop an in vitro chromosome doubling systems for the breeding of tetraploid lily cultivar. Different concentration (ppm) and treatment time (hour) of colchicine, oryzalin and caffeine were compared for the efficiency of bulb regeneration and tetraploidization. The occurrence of tetraploid plants by colchicine was the highest in the concentration of 1,000 ppm for three hours. In oryzalin treatment, the best combination was at 30 ppm for three hours. However, the effects of oryzalin treatments were similar between 10 ppm and 30 ppm concentrations. The survival rate was dramatically reduced in a high concentration of caffeine although some treatments had a higher tetraploid induction. As a consequence, reliable results for the tetraploid production were obtained in the treatments of 1,000 ppm colchicine, 3,000 ppm oryzalin both for three hours, and 9,000 ppm caffeine for nine hours.

Background: Ginseng essence (GE) is a formulation comprising four medicinal and edible herbs including ginseng (Panax ginseng), American ginseng (Panax quinquefolius), lotus seed (Nelumbo nucifera), and lily bulb (Lilium longiflorum). This study was aimed at investigating the hepatoprotective effect of GE against carbon tetrachloride ($CCl_4$)-induced liver injury in rats. Methods: We treated Wistar rats daily with low, medium, and high [0.625 g/kg body weight (bw), 1.25 g/kg bw, and 3.125 g/kg bw, respectively] doses of GE for 9 wk. After the 1st wk of treatment, rats were administered 20% $CCl_4$ (1.5 mL/kg bw) two times a week to induce liver damage until the treatment ended. Results: Serum biochemical analysis indicated that GE ameliorated the elevation of aspartate aminotransferase and alanine aminotransferase and albumin decline in $CCl_4$-treated rats. Moreover, $CCl_4$-induced accumulation of hepatic total cholesterol and triglyceride was inhibited. The hepatoprotective effects of GE involved enhancing the hepatic antioxidant defense system including glutathione, glutathione peroxidase, glutathione reductase, glutathione S-transferase, superoxide dismutase, and catalase. In addition, histological analysis using hematoxylin and eosin and Masson's trichrome staining showed that GE inhibited $CCl_4$-induced hepatic inflammation and fibrosis. Furthermore, immunohistochemical staining of alpha-smooth muscle actin indicated that $CCl_4$-triggered activation of hepatic stellate cells was reduced. Conclusion: These findings demonstrate that GE improves $CCl_4$-induced liver inflammation and fibrosis by attenuating oxidative stress. Therefore, GE could be a promising hepatoprotective herbal formulation for future development of phytotherapy.

To develop Korean native lilies as mini-potted plants, the effects of plant growth retardants on inhibiting stem elongation and improving flowering rate were evaluated. Bulblets of Lilium concolor var. parthneion (5-7 g) and L. dauricum (3-4 g fresh wt) derived from in vitro culture and then enlarged by field culture were applied with 0, 25, 50, or $100mg{\cdot}L^{-1}$ ancymidol, diniconazole, and uniconazole through bulb dipping, foliar spray, and drench. In L. concolor var. parthneion, uniconazole dipping most effectively reduced plant height by 60.7-78.3% depending on concentration compared with control without decreasing flowering percentage. In L. dauricum, dipping into diniconazole solution significantly retarded the plant height by 70.0-86.3% and improved flowering percentage by 8.3-18.2% compared to control of 0%. Drench of $25-50mg{\cdot}L^{-1}$ ancymidol was also effective on inhibition of stem elongation and improvement of flowering rate. Therefore, dipping into $50-100mg{\cdot}L^{-1}$ uniconazole solution in L. concolor var. parthneion and dipping into $25mg{\cdot}L^{-1}$ diniconazole solutions or drench of $25mg{\cdot}L^{-1}$ ancymidol in L. dauricum can be useful to produce the mini-potted plants.

In this study, Lilium sp. were separated into bulbs, leaves, and flowers. Then, total polyphenol contents, electron donating ability (EDA), superoxide dismutase (SOD)-like activity, hydroxyl radical scavenging activity, and antimicrobial activity were measured from the extracts of each of the three aforementioned parts. The examination of physiologically active substances in the three parts revealed that Lilium davidii leaves had high total polyphenol contents, SOD-like activity, hydroxyl radical scavenging activity, and EDA, while the flowers of L. lancifolium showed high SOD-like activity, hydroxyl radical scavenging activity, and EDA, as well as a high level of total polyphenols in the bulb. Measurements of the antimicrobial activities of the extracts against Gram positive bacteria revealed that the leaves and flowers of L. davidii and L. lancifolium caused Bacillus subtilis and Salmonella enteritidis to form clear zones greater than 10 mm. Furthermore, the flowers of L. lancifolium showed particularly high antimicrobial activity against B. subtilis, and the flowers of L. davidii had high activity against S. enteritidis. For the Gram negative bacteria, the leaves and flowers of L. davidii and L. lancifolium caused Listeria monocytogenes and Escherichia coli to form clear zones greater than 10 mm, and finally, the flowers of L. davidii and L. lancifolium showed high antibacterial activity, with inhibition exceeding 12 mm.
