  • Regarding the physical properties of wheat flour added with lily's root powder, elasticity in farinograms tended to increase as the ratio of added lily's root powder increased. However, viscoelasticity, absorptivity, absorption time, and stability tended to decrease after an initial increase when a certain ratio of lily's root powder was added to the wheat flour. Results from the rapid viscosity analyzer (RVA) indicated that the retention strength, final viscosity, break down, set back value, $P_{max}$ value of the alveogram, and falling number value decreased. As for gaseous release, measured with a rheofermentometer, the total amount of $CO_2$ gas generated and retained tended to decrease. As for the gelatinizing properties in terms of differences in the granularity and the amount of lily's root powder (bulbs) added to wheat flour, the initial gelatinization temperature had no effect regardless of the type or amount of general grinding and minute (ultra-fine, $10\;{\mu}m$) lily's root powder. Meanwhile, the peak viscosity and peak viscosity time exhibited significant differences in 3, 5% general grinding lily's root powder additive groups. On the other hand, there was no significant difference between 3, 5% minute lily's root powder additive groups. This is likely because the activity of the enzyme in wheat flour decreased relatively and differences in the lily's root powder granularity resulted in a variation in water absorptivity. In the preference test, flavor retention of the functional bread increased according to the granularity of lily's root powder and the ratio of added lily's root powder, thus resulting in significant differences in the mouth feel and flavor; the texture and crumb color, however, did not exhibit significant differences.

  • Growth and tuber development of ‘Black Magic’calla lily as affected by the rain shelter with 50% shading and the tuber size were investigated. Tubers of five grades in size were cultivated in the rain shelter or in the open field (control). Days to emergence of shoots in the rain shelter was accelerated by 4.2 days as compared to the open field. Emergence ratio was higher as the tuber was larger, tubers grown in the rain shelter showed the significance in the growth characteristics as compared to the control. There were no significant differences in the number of flowers per tuber between the rain shelter and the open field. Flower quality was 12.2 cm longer than that in the open field. flowering characteristics was improved with the increasing tuber size. Low infection of soft rot disease of 3∼22% was found in the rain shelter as compared to the that of 19∼83% in the open field. Thus tubers produced under the rain shelter showed improved quality, Even if the small tubers with diameters of 0.5∼1.0 cm were cultivated in the rain shelter, the weight and diameters of tuber harvested after approximately 7 months were 50.2 g and 5.7 cm, respectively.

  • Yam bean (Pachyrhizus erosus) is a subtropical plant belonging to the Fabaceae family, and is a tuberous vegetable used as various food material with a crisp and juicy taste. This study was conducted to seek optimum sowing time of yam bean in Korea. For this, we surveyed germination properties by the different temperatures and compared the accumulation temperature (AT) and dry matter production (DMP) on growth stages of yam bean by the different sowing times. Two types of varieties cultivated mainly in Korea, Thailand local variety (TLV) and Cheongunmanma cultivar (CGMM), was used. The germination rate of yam bean was 86.0~94.0% at above $18^{\circ}C$, and germination days was longer at lower temperature. The times for flowering and tuber formation of CGMM were later than those of TLV, and the AT required for flowering, tuber formation and hypertrophy of CGMM were higher than those of TLV by $293^{\circ}C$, $280^{\circ}C$ and $108^{\circ}C$, respectively. Also, DMP of shoot and tuber in CGMM were greater than those in TLV. In sowing at April 25, tuber formation was slower than sowing after that time, and harvest index (HI) was relatively low due to delayed formation and hypertrophy of tuber. In sowing after June 9, DMP of shoot was relatively greater in early growth, but tuber was not sufficient to enlarge due to lack of growth days by cold and frost in late October. In sowing May 10 and 25, DMP of tuber and HI were the highest, because the change of day length and temperature gave an advantage to vegetable growth and tuber development. All above suggest that it was suitable to sow seeds on May for increment of tuber productivity in Korea.

  • 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.

  • Several pathogens associated with bulb rot of lilies in storage house were identified with respect to rot types. Rot patterns were grouped into four different types; brown rot of bottoms, brown rot of shoots, water-soaked rot and blue mold. Brown rot of bottoms was the highest in frequency with 72.5%, and brown rot of shoots the least with 23.0%. Dominant pathogens were differed with rot patterns, brown rot of bottoms by Fusarium oxysporum, blue mold and brown rot of shoots by Penicillium brevicompactum and P. fellutanum. In wound-inoculation tests, Penicillium and Fusarium isolates caused severe rot on the bulbs. Bulb disinfection before storage by captan showed the most prominent control value of 95.2% followed by thiophanate-methyl with 85.6%.

  • 'Arirang', an early-flowering pure white gladiolus with purple core, was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 1998. The selection was derived from the cross between the progenies of the early flowering dark orange 'Arianne' and bright red domestic cultivars 'Hongkwang'. The breeding was conducted in 1993 and finally selected in 1998 after five (5) years (1994 to 1998) of experimentation. 'Arirang' is a cut flower with bright white color petals and purple core which exhibited early flowering and vigor without stem bending. These can be cultivated in areas or regions with strong winds during summer. 'Arirang' has a very firm growth form and sturdy branches which do not bend when planted in the open fields. Likewise, the plant had high tolerance to flooding and resistance hence could grow vigorously in open areas. It is a fast- growing plant which exhibits high corm production rate. 'Arirang' had a 10.5 cm wide flower and 140 cm plant height. During summer, the average number of days to flowering was recorded at 75 days of 'Arirang'. Top dressing must be conducted once or twice during corm production to enhance corm quality and quantity.
