This study was conducted in order to predict the vase life of cut lily 'Woori Tower' flowers using a non-destructive thermal imaging technique. It was found that the temperature of cut lily flowers was maintained at 20℃ and was slightly lower than the air temperature until they bloomed. On the 11th day, when flowers bloomed, the temperature of leaves and flowers was measured to be 18.75±0.38℃ and 19.23±0.32℃ respectively, and their difference with ambient temperature was over 3℃. The flower temperature increased slightly when the vase life of cut lily flowers ended, and the temperature difference between the air and leaf temperature (1.77℃) and between the air and flower temperature (1.39℃) got smaller. No visible aging symptom was observed, but it was found that the temperature had risen due to water losses and less functional stomata. The vase life of cut lily flowers can be predicted based on changes in temperature and it will be also possible to predict the potential quality and vase life of cut flowers before harvesting them in greenhouses.

Calla lily is one of the most iconic and widely recognized ornamental plants. This study compared the extracts of 11 cultivars of domestic calla lily bred by the National Institute of Horticultural and Herbal Science for their total polyphenol and antioxidant activities. Eleven cultivars were evaluated for their growth and flowering characteristics as per the Manual for Agricultural Investigation Rural Development Administration (RDA) form. The antioxidant activities were measured using 2,2'-azinobis (3-ethylbebzothiazoloine-6-sulfonic acid)-diammounium salt (ABTS⁺) and 1,1-diphenyl-2-picrrylhydrazyl (DPPH) radical scavenging effect. The plants have an average height of 63.80 ± 5.4 cm, average flower diameter of 7.2 ± 1.1 cm, and width of 12.4 ± 1.7 cm. On average, the diameter and width of leaves were 33.7 ± 3.5 cm and 20.0 ± 1.4 cm, respectively. Extracts of flowers and leaves in the 11 cultivars of white calla lily were compared for their antioxidant activities and total polyphenol contents. ABTS⁺ and DPPH radical scavenging, which are indicative of antioxidant activity, were higher in flowers than in leaves. When comparing by cultivar, we found that 'White Egg' showed the highest antioxidant activity in both the flowers and the leaves. Additionally, we found that by part, the content of total polyphenols was highest in flowers, and by cultivar, it was highest in the 'Swan' and 'White Egg' cultivars. Furthermore, the days to flowering showed correlations with ABTS⁺ radical scavenging, total phenolic contents (TPC), and total flavonoid contents (TFC). Our results indicate that calla lily can be used as breeding material material according to its growth characteristics and as a natural antioxidant source.

"Hyehwa" an Asiatic lily cultivar was released in 1998 at National Institute of Horticultural and Herbal Science (RDA), Suwon, Korea. The cross was made in 1991 between Asiatic lily "White Bird", a white colored, and "Avignon", an unspotted scarlet red colored. It was preliminarily selected as A93-20 in 1993. Its multiplication, bulbing growth and flowering characteristic tests were conducted from 1994 to 1998. A new cultivar "Hyehwa" flowers in middle of June and grows 98.7 cm in height. Flowers bloom upward-facing, thick orange (RHS, 28A). Year-round flowering is possible by storage of the bulb under $-1.5^{\circ}C$ conditions. For forcing culture, it is necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. Botrytis disease control is needed in the wet season.

The cut lily is one of the most important exporting flowers in Korea, which value is 19.9 million dollars in 2013. However, Korean farmers and exporting firms recently have experiences a large decrease in lily export, and need to find the way to the increasing exportation. The purpose of this paper is to analyze the situation of production and consumption of the cut lily in the world and to present the implication for the acceleration of exportation of Korean cut lily. The results of studies present a few findings: First, Korean farmers and business firms need to study and benchmark the production and exportation system of Netherlands which is the best country in the world. Second, Colombia, Kenya, Ecuador and Ethiopia are also need to be studied for the upgrading Korean system of exportation of cut lily. Third, Korean farmers and business firms should continuously monitor the three main markets of cut lily (EU, U.S., and Japan), and develop strategies for the exportation of Korean cut lily. Forth, especially, Korean farmers and business firms should define the preference of cut lily in the main exporting markets (Japan, China, Russia), including breed and color of flower, and the main period of consumption, in order to develop the marketing strategy for Korean cut lily.

BACKGROUND: Yeast isolates associated with the leaves, stems, and flowers of the tiger lily needed to be identified using isolation methods that have previously been used effectively in yeast biotechnology. A culture-based approach was necessary for the isolation of many yeast strains associated with tiger lily. METHODS AND RESULTS: In this study, the homogenized leaves, stems, and flowers of tiger lily were spreaded onto GPY medium containing chloramphenicol, streptomycin, Triton X-100, and L-sorbose. A total of 82 yeast strains from the leaves, 94 and 97 yeast strains from the stems and flowers were isolated, respectively. Yeast isolates were identified by phylogenetic analysis based on internal transcribed spacer region sequencing. The yeast species isolated from the leaves comprised of 31 isolates of the genus Pseudozyma, 28 of Aureobasidium pullulans, and 11 of the genus Cryptococcus. Those isolated from the stems comprised of 40 of A. pullulans and 11 of Cryptococcus, and 95 of A. pullulans While, 1 isolate each of the genera Rhodotorula and Metschnikowia were isolated from the flowers. CONCLUSION: We identified site-specific yeast communities associated with tiger lily. These yeast isolates may have high potential for application in the field of biotechnology.

In order to determine the relationship between water content and flower qualities of oriental hybrid lily cv. 'Siberia' cut flower, flowers were subjected to dry and cold storage at $5^{\circ}C$ for 3, 6, and 12 days and subsequently exposed to ambient temperature ($26^{\circ}C$) in bottles with water for up to 16 days. Flowers stored at $22^{\circ}C$ in dry condition for 3 days were used as the control. Changes in fresh weight, moisture content, water balance, flowering stages, osmolality and vase life of cut flowers were observed. Flowers treated with cold and dry storage had higher moisture content compared to control sample. However, this trend was evident only for 3-day cold and dry stored sample during the whole storage period. The fresh weight of cut flowers increased gradually when the samples were transferred to ambient temperature in water bottles and then declined steadily before reaching the peak in between 6-8 days of vase life. However, the changes of fresh weight of control sample were substantially faster than samples pre-treated with cold and dry storage. This was also correlated with the water balance of cut flower as it reached the minus (-) value in 6-8 days of vase life at ambient temperature. Cut lily flowers showed high osmolality values corresponding with the duration of dry storage regardless of low or higher temperature. However, osmolality had no effect on vase life since flower stem absorbed water rapidly at the end of dry storage period. Our vase life results suggest that cold and dry storage of lily cut flowers for a certain period could ensure longer vase life at ambient temperature. It was observed that prolonging the storage period at cold and dry condition for more than a week significantly increased bud abortion, reduced longevity of flowers and reduced the vase life of cut flowers. On the other hand, the shorter cold and dry storage treatment delayed the bud opening and senescence of the flowers, thus, slowering the normal maturation and aging. Results indicated that dry and cold storage at $5^{\circ}C$ for 3 days was effective in maintaining and preserving overall quality and vase life at ambient condition of oriental hybrid lily cut flowers.

This study was conducted to clarify the effects of daminozide (butanedioic acid mono-(2,2 - dimethylhydrazide)) sprayed 2 days be fore harvest and floral preservative solutions on longevity, quality and ethylene production of 'Georgia' cut lily for prolonging vase life and improving quality of cut lily flowers. And also the relation between ethylene production and flower senescence of cut lily was studied. 1. Lilies held in silver nitrate ($AgNO_3$) at 25 and 50 ppm were increased in solution uptake, fresh weight, and flower longevity. The solution of 2.5% sucrose+50 ppm $AgNO_3$+200 ppm aluminum sulfate+10 ppm 6-benzylamino purine prolonged vase life and improved quality of cut lily flowers. 2. Lilies sprayed with 500 ppm daminozide 2 days be fore harvest and then held in the preservative solution (5% sucrose+50 ppm $AgNO_3$+150ppm 8-hydroxyquinoline) after harvest were significantly increased in fresh weight and vase life as compared with non-sprayed (control) flowers. 3. Ethylene production from cut lily was increased by ethephon ((2-chloroethyl) phosphonic acid) treatment. The flowers producing a lot of ethylene, however, were senesced slowly instead of rapid wilting. 4. The preservative solution markedly reduced ethylene production of cut lily but prolonged vase life for only a few days. 5. These results suggest that ethylene be one of the most important factors promoting flower senescence of cut lily, but it be very difficult to prolong vase life remarkably by only inhibition of ethylene production in cut lily.
