This study was conducted to investigate the utilization of cut pear branches for dyeing materials, and the dyeability of pear flowers for pressed flowers using red, orange, and green edible pigments. There was a significant difference of E values among 0.1, 0.5 and $1.0{\%}$ diluted solutions of edible pigments for the cut pear branches coming into flowers. In the higher concentrations of dyeing solutions and the longer dyeing periods, a values with the red pigments increased from 2.37 to 31.22, b values with the orange pigments increased from 7.04 to 45.85, and a - values with the green pigments increased from -3.88 to -36. Bloomed pear branches were immersed in diluted solutions with red, orange and green pigments for forty five minutes. Pear branches immersed in $0.1{\%}$ and $0.5{\%}$ diluted solutions bloomed normally, and each of the flowers were dyed in the colors of the dyeing solutions, respectively. The dyeability of the bloomed pear branches immersed in water and dyeing solutions for one hundred and twenty minutes decreased compared with those treated with red, orange and green pigments and dyed immediately. The dyeability of flowers for the cut pear branches dyed immediately after cutting was significantly increased compared with that immersed in water and dyeing solutions.

Gray mold caused by Botrytis cinerea is one of the most important postharvest fungal pathogens of cut flowers. Here, gamma irradiation, an alternative for phytosanitary purposes, and sodium dichloroisocyanurate (NaDCC) were used to control B. cinerea in a cut chrysanthemum (Chrysanthemum morifolium Ramat.) cultivar, 'Baekma', one of the cultivars susceptible to B. cinerea. Spore germination and mycelium growth of B. cinerea were inhibited by gamma irradiation in an inversely dose-dependent manner. A dose of 4 kGy completely inhibited the mycelium growth of B. cinerea. A significant change in flower quality (physical properties) on chrysanthemum was shown from gamma irradiation at over 0.2 kGy (p<0.05). Therefore, in this study, the integration of gamma ray (below 0.2 kGy) and NaDCC, an eco-friendly form of chlorine, was investigated to control the disease with low dose of gamma irradiation dose. Interestingly, the gamma irradiated flowers showed more disease severity than the non-irradiated flowers. The combined treatment of gamma irradiation and NaDCC does not affect the severity of the fungal disease, whereas only 70 ppm of NaDCC treatment showed a significantly reduced severity. These results suggest that only chlorination treatment can be applied to control B. cinerea in cut chrysanthemum flowers.

This study aimed to provide basic data on current trends in floriculture through a survey. The exhibitors' purposes and items displayed at the Tokyo International Flowers & Plants Expo in 2017 were surveyed. The survey was conducted among 238 exhibitors during the exhibition period from October 11 to 13, 2017. As a result, participants came from 14 countries including Belgium, China, Colombia, Japan, Korea and France. The purposes of the majority of the surveyed exhibitors were to display cultivars (86 exhibitors, 36.3%), followed by to display merchandise, subsidiary materials and cultivation techniques. Among cultivars, pot plants accounted for the majority of the entire cultivars (54 exhibitors, 55.1%), followed by cut flowers (35 exhibitors, 35.7%), sapling, and seeds. The most of the displayed pot plants were ornamental plants (27 exhibitors, 43.5%), followed by garden trees, ground cover plants, bedding plants and succulent plants. The most of the displayed cut flowers were rose (8 exhibitors, 21.1%), followed by lisianthus, chrysanthemum and dahila. In terms of cultivation techniques, those using moss were displayed by 7 exhibitors (50%) and green-wall techniques were displayed by 6 exhibitors (42.9%). In terms of merchandise, processed products were displayed by 21 exhibitors (41.2%), followed by floral products. Therefore, the IFEX can be used as a place to understand current trends in the floriculture market.

The Objective of this study was to investigate the effect of ethylene exposure and silver thiosulfate (STS) on flower senescence and vase life of cut iris (Iris hollandica). Cut iris flowers were pretreated in 1 mM STS solution for 30 minutes and exposed to 0, $3mL{\cdot}L^{-1}$ethylene for 24 hours. The vase life of iris treated at a bud stage was showed day 4.2 by exposure to $3mL{\cdot}L^{-1}$ ethylene and day 4.6 by exposure to $0mL{\cdot}L^{-1}$ ethylene. The pulsing of STS increased vase life of iris treated at a half-open stage. But, the vase life of iris was not affected by exposure to ethylene. Therefore, iris flowers were not sensitive to ethylene exposure. Iris flowers harvested at a bud stage do not progress to fully open flowers and then show flower senescnce, the optimum harvest stage seems to be a stage when flowers are open to some degree.

This study was carried out to investigate the effects of shipping temperature and harvesting stage on the quality and vase life of cut flower in standard chrysanthemum 'Baekma' for export. Cut flowers harvested at flowering stage 4 were stored for 24 hours at $5^{\circ}C$, and then quality and vase life were evaluated after simulated shipping for 48 hours at 5, 20, and $35^{\circ}C$. In addition, cut flowers harvested in flowering stage 1 to stage 6 were evaluated after simulated shipping for 72 hours at $5^{\circ}C$. As shipping temperature increased, $CO_2$ concentration inside the box rapidly increased, and $O_2$ concentration greatly decreased. The vase life of cut flowers was extended by 3 days and chlorophyll content of leaves, fresh weight, solution uptake, and flower diameter were better maintained in $5^{\circ}C$ shipping than in 20 or $35^{\circ}C$ shipping. The vase life of cut flowers harvested at flowering stage 1 or 2 was extended by 5.2 or 5.5 days compared to those harvested at flowering stage 6, more 6. The fresh weight was lower and flower diameter was smaller by 1.3 or 2.5 cm in cut flowers of flowering stages 1 through 3 than flowering stages 4 through 6. In addition, the cut flowers of flowering stages 4 through 6 showed higher solution uptake than those of flowering stages 1 through 3. These results suggest that shipping at $5^{\circ}C$ of cut flowers harvested at flowering stage 4 is preferential for promoting vase life and quality of cut flower in standard chrysanthemum 'Baekma' for export to Japan.

This study was carried out to analyze the effect of changes in the light environment caused by the daylight disturbance on the growth, flowering, and cut flower quality of spray chrysanthemums. The spray chrysanthemum 'Yellow Cap' and 'Pitch PangPang' cultivars for cut flowers were artificially shaded to interfere with 66% of sunlight compared to the non-shading, and then the growing and flowering characteristics, and cut flower yield were investigated accordingly. There was no significant difference in the cut flower yield per unit area between the shading and the non-shading treatments. However, the number of days to flowering was 72.1 days for the 'Yellow Cap' and 65.2 days for the 'Pitch PangPang', which were delayed by 14.1 and 8.9 days, respectively, compared to the non-shading light. In the shading treatment, the flower diameter and the number of flowers also decreased by 10% and 15%, and 30% and 28% for both 'Yellow Cap' and 'Pitch PangPang', respectively. The stem length also decreased by 10% and 20%, the stem diameter by 23% and 37%, and fresh weight by 32% and 33%, respectively. The shading treatment delayed the flowering of chrysanthemums and reduced the growth such as flower diameter, number of flowers, and the length and weight of cut flowers. Based on these results, the daylight disturbance by artificial buildings is expected to reduce the productivity and quality of cut flowers by limiting the light intensity needed for chrysanthemum growth, flower bud differentiation, and flower development. Therefore, further research is needed on the rate of decrease in yield and market value according to the degree of shading to relieve damage to chrysanthemum growers caused by the daylight disturbance.

Floral scents and metabolites from cut flowers of 14 peony cultivars (Paeonia lactiflora Pall.) were analyzed to discriminate different cultivars and to compare the Korean cultivar with the other cut peonies imported to Korea using electronic nose (E-nose) and Fourier transform infrared (FT-IR) spectroscopy combined with multivariate analysis, respectively. Principal component analysis (PCA) and discriminant function analysis (DFA) dendrogram of peony floral scents were not precisely same but there were 3 groups including same cultivars. PCA and partial least squares-discriminant analysis (PLS-DA) dendrograms of peony metabolites showed that different cut peony cultivars were clustered into two major groups including same cultivars. Fragrance pattern of Korean 'Taebaek' was classified to same group with 'Jubilee' on the PCA and DFA results and its metabolite pattern was clearly discriminated by the PCA and PLS-DA compared to the other cultivars. These results show that the 14 peony cut flowers could be discriminated corresponding to their chemical relationship and the metabolic profile of Korean 'Taebaek' has distinctive characteristics. Furthermore, we suggest that these results could be used as the preliminary data for breeding new cut peony cultivars and for improving the availability of Korean cut peony in cosmetic industry.

In order to improve cut-flower export packaging on the distribution process, newly developed T-type(trapezoid type) container was tested and evaluated on the viewpoints of the protection, workability, and economics. T-type container performed better in protection and workability comparing to 0201 and modified 0201 type containers. Especially, load efficiency of T-type container was 33 percent higher than others, indicating that total distribution costs from Korea to Japan can be saved up to 1.7million dollars per year. T-type container is also advantageous because of its superior display performance and environmentally friendly design. We recommend that T-type container is suitable for most of cut-flowers which are usually horizontally packed such as roses, chrysanthemums, and lilies.

The opening process of cut calla flower was faster at 30 t than at lower temperatures as it could be expected from its tropical origin. Gibberellin enhanced the flower opening, however, it also speeded up senescent. Silver thiosulfate was effective in prolonging the vase life of the cut calla flower. Silver thiosulfate reduced ethylene generation by the flower and inhibited microbial growth in the flower stalk. Reduction in ethylene generation and inhibition of microbial growth is thought to be responsible for the extension of the vase life of cut calla flowers by silver thiosulfate.
