This study was conducted to investigate tissue nutrient contents and salt accumulation in plastic house soils cultivating lily, rose and carnation. The soil tested had high total salts, available phosphate and exchangeable potassium. The soil cultivating rose had highest salt concentvation followed by chose of carnation and lily. Tissue nutrient contents of lily were higher than chose of carnation and rose. In comparison among cultivars, the nutrient contents were as follows; 'Snow Qeen'>'Le Reve'>'Casa Blanca' in lily; 'Marina'>'Super star'>'Mary Devor'>'Madelon' in carnation; and 'Cocktail'> 'Marina'>'Maderon' in rose. The range of the nutrient contents were: T-N: $1.66\;{\sim}2.35%$, K: $1.73{\sim}2.23%$, Zn: $2.13{\sim}6.43\;mg/kg$, Cu: $3.79{\sim}13.89\;mg/kg$ in carnation; T-N: $0.79{\sim}1.65%$, P: $0.18{\sim}0.44%$, Ca: $0.59{\sim}1.26%$, Mg: $0.21{\sim}0.46%$, Zn: $23.65{\sim}90.30\;mg/kg$, Cu: $0.99{\sim}4.62\;mg/kg$ in lily; and T-N: $0.75{\sim}1.62%$, P: $0.17{\sim}0.30%$, K: $1.60{\sim}2.91%$, Ca: $0.64{\sim}0.94%$, Zn: $24.57{\sim}48.31\;mg/kg$, Cu: $3.10{\sim}9.08\;mg/kg$ in rose. The amount of nutrients uptake per plant was high in order of: K > T-N > Ca > Mg in lily; and T-N > K > Ca > P > Mg in rose.

Lily is an important cut-flower in Korea and world as well due to it's a variety of flower colors and various sizes of flowers. To develop elite lily cultivars, conventional breeding techniques have been used so far. However, an introduction of tissue culture system in mass propagation of bulbs and regeneration of shoots with a high efficiency is prerequisite at this moment. Especially, growth of bulbs and shoots as well as reduction of browning is critical factor to proliferate bulbs with shoots of superior lines or cultivar in lily. For this purpose, we tried to test whether ascorbic acid, citric acid and silver nitrate in medium to facilitate growth of bulbs and shoots as well as reduction of browning of bulb scales in lily. As a result, ascorbic acid and silver nitrate showed no significant differences compared to control plants in the growth of bulbs and shoots. When bulb scales were treated with $150mg{\cdot}l^{-1}$ of citric acid, formations of shoots and bulbs showed best result. While, bulb scale treated with $100mg{\cdot}l^{-1}$ of citric acid showed the growth of shoot and root as well as increasing of fresh weight compared to other treatments. Regarding the reduction of browning, $150mg{\cdot}l^{-1}$ of ascorbic acid showed the best result with the less than 2%. Although more experiments with several commercial varieties are needed in the future to establish mass propagation of bulbs of lily, results obtained in this study are supposed to provide the basic knowledge and contribution in tissue culture system of lily.

In May 2020, necrosis and necrotic ring patterns were observed on leaves of three of 140 Iris domestica plants in a demonstration garden in Wanju, Jeollabuk-do. Three symptomatic plants were found to be infected by tomato spotted wilt virus (TSWV). To analyze the whole genomic sequence of one TSWV isolate, 'Blackberry lily-kr1', L, M, and S genome segments were sequenced and analyzed by comparison of nucleotide sequences of the three segments with corresponding sequences of other TSWV isolates. 'Blackberry lily-kr1' isolate was most closely related to 'JJ' isolate (MF159046) or 'HJ' isolate (LC273305) in the L segment, and to 'JJ' isolate (MF159058 and KY021439) in the M and S segments, respectively. Phylogenetic analysis by Maximum likelihood method using MEGA X program with 'Blackberry lily-kr1' isolate showed high relationship with 'JJ' pepper isolate or 'HJ' Humulus japonicas isolate in the all three segment. Necrosis and double ring patterns on leaves were formed in the glasshouse after inoculation of healthy I. domestica plants with sap of 'Blackberry lily-kr1'-infected Nicotiana rustica plants. This result suggests that I. domestica plants showing necrotic ring patterns in the open field are caused by TSWV infection. This is the first report of TSWV infection of I. domestica in Korea.

Rhizopus soft rot of lily (Lilium longiflorum) caused by Rhizopus oryzae was observed in the experimental field in Taean Lily Experiment Station in Korea, 2012. The typical symptoms were water-soaked lesions on bottom stem and leaf rot. The lesion rapidly expanded and the plant was softened totally. The fungus grew vigorously at an optimum temperature ($25^{\circ}C$) and brownish colony and black sporangia were formed on potato dextrose agar medium. Sporangiophores formed on end of sporangia were sub-globose, brownish and $6-10{\mu}m$ in size. Sporangia were globose, blackish and $87-116{\mu}m$ in size. Sporangiospores were irregularly oval and sub-globose, brownish $4-8{\mu}m$ in size. On the basis of mycological characteristics, analyzing sequences of internal transcribed spacer region of ribosomal DNA, and pathogenicity test on host plants, the causal fungus was identified as R. oryzae. This is the first report of Rhizopus soft rot on lily caused by R. oryzae in Korea.

Seven phytoplasma diseases have been occurred on floricultural crops in Korea : Ph-ch1 and Ph-ch2 of chrysanthemum, Ph-lily of lily, petunia flat stem-Korean (PFS-K) of petunia, poinsettia branch inducing- Korean (PoiBI-K) of poinsettia, statis witches' broom-Korean (SWB-K) of statis and azalea witches broom (AWB). Classification of the seven phytoplasmal diseases based on 16S ribosomal RNA (rRNA) sequences showed that floricultural crop phytoplasma disease were widespread in order of aster yellow (AY), stolbur and X-disease in Korea. In phenotypic characters, the fasciation was occurred in both monocotyledon plant of lily and dicotyledon plants of petunia and poinsettia. Besides, the fascination was occurred in Ph-lily of stolbur, petunia PFS-K of AY and PoiBI-K of X-disease. This result indicated that phytoplasma classification based on 16S rRNA and symptoms are not consistently related. The comparison of 16S rRNA sequence of the seven floricultural crop phytoplasma with five tree phytoplasmal diseases of jujube witches' broom, paulownia witches' broom, wild jujube witches' broom, mulberry dwarf, golden rain phytoplasma occurred in Korea showed as high as 88.5-99.9% homology. Among them, especially mulberry dwarf showed the highest homology with the seven floricultural crop phytoplasms. Based on this result, floricultural crop phytoplasmas were assumed to be transmitted by insect vectors from tree phytoplasmas in Korea.

The seventy nine isolates of Botrytis spp. were obtained from leaf blight lesions of lily in Korea, Japan and Netherlands. Morphological and cultural characteristics of them were investigated and molecular characteristics of them were determined using sequence analysis of RNA polymerase II (RPB2) and heat-shock protein 60 (HSP60) gene. A selection of Botrytis isolates were evaluated for their pathogenicity to lily. Based on morphological and cultural characteristics, the Botrytis isolates were divided into two groups, and identified as B. elliptica (n = 54) and B. cinerea (n = 25). Based on analysis of RPB2 and HSP60 sequences, the Botrytis isolates were also divided into two groups and well supported morphological groupings. Spore suspensions of B, elliptica showed significant pathogenicity on lily leaves and flowers, however those of B. cinerea showed pathogenicity only on flowers but not on leaves. The latter showed pathogenicity on lily leaves only when spore suspensions amended with PDB were used as inocula.

Lily is one of the most important 5 cut flowers in international flower market and lilies are distributed in Asia, Eurasia and North America. To develop a new lily cultivar, in addition to hybridization, mutation and selection methods, biotechnological techniques including tissue culture are also required. Establishment of tissue culture system is one of the requirement for the breeding program in Lily. Among many fields of plant tissue culture, establishment of regeneration system via embryogenic calluses are studied in many crops. In this study, research was carried out to decide the proper concentration of picloram which is used for the induction of embryogenic calluses. As a result, 3 different types of callused were observed after 3-4 weeks. They were CEC (compact embryogenic callus), FEC (friable embryogenic callus) and white callus type. 1.0 mg /l of picloram showed the best result for the production of embryogenic callus, however, due to its higher rate of browning in this concentration, 0.75 mg/l of picloram was selected as a proper concentration of picloram for the induction of CEC and FEC in Lily. These results can be contributed to the establishment of both regeneration system and mass propagation in lily in the future.

In this study, the efficacy of water lily(Nymphaea tetragona) leaves as a new natural dye resource was investigated. For this purpose, the colorants from water lily leaves were extracted in methanol, evaporated, and powdered. Dyeing onto cotton fiber was carried out to study the effects of dyeing conditions, mordant type and mordanting method on dye uptake, color change, and colorfastness. FTIR analysis supported that hydrolyzable tannins and chrolophyll were contained in the extracted colorants. The colorants showed good affinity to cotton fiber showing Y Munsell color. Pre-mordanting method gave better results in terms of dye uptake than post-mordanting method. By mordanting, dyed fabrics exhibited various colors such as green, khaki, brownish yellow, dark brown, dark gray and so on. Colorfastness to washing and rubbing was relatively good showing 4-5 rating. The light fastness was improved 1-2 rating by Fe mordanting. The dyed cotton fabric showed antimicrobial activity.

This study presents a new fashion wearable product, a classical music stage costume design, using an Arduino LilyPad that can control light-emitting diodes(LEDs) and a sound sensor that can set an environmental range of LED light. As a theoretical background, LED fashion design research and stage costume design research status were reviewed, and Arduino LilyPads, sensors, LEDs, and batteries required for LED stage costume production were investigated. Based on prior research, the LED stage costume design for the soprano stage was presented in a three-step process of design planning, development, and production, and an actual prototype was produced. This process produced meaningful information and materials for making clothes with the added function of a wearable computer. In particular, fashion designers or fashion majors can easily access the Arduino LillyPad and use not only LEDs, but other light emitting materials. It is expected that it will be used as a basic material for the use of the Arduino LillyPad that can develop new creations that have been utilized.
