Results
1) A survey on the variation of the vase life of the cut roses based on the growing types and changing growth environments in each season
○ In order to enhance the growing environment in farms, the relative humidity during winter changed to 70% or less from the existing condition of 80% or lower, or it is necessary to change the humidity conditions during the day and night. The differential of the vapor pressure deficit (VPD) should be increased from the existing condition of less than 0.8kPa to around 1.2kPa. Also, it is possible to increase the potential shelf life of the cut flowers by around five days through reducing the humidity in the high humidity greenhouse environments during the winter seasons or making changes with such values.
○ In order to enhance the growing environment in each season, the average time of sunlight in a greenhouse for roses during winter should be 30∼35wat/m2, while the proper temperature range should range from 22 to 25℃. If the RH in the green house during winter is high, the vase life of the cut flower goes up slightly. However, the quality of the cut flower, such as the vase life of the cut flower after harvesting, is decreased. Therefore, it is recommended to reduce the lowest RH per day to 60% or lower or give a wider variance in the humidity condition between day and night. The optimal condition for the VPD differential is to maintain the level between 1.7 and 2.3kPa or give variances. Under an optimal environment before harvesting, the potential vase life of a cut flower may be increased by up to seven days.
○ It was shown that, through the controlling of the humidity condition in the greenhouse during winter, the stoma of cut roses can be enlarged and the functioning of the stomas can be degrade, resulting in rapid loss of water from the cut flowers after harvesting. Therefore, in order to produce cut roses of higher quality, it is critical to enhance the post-harvest quality and freshness of the cut roses by controlling the humidity conditions in the green house. In order to enhance the post-harvest quality of winter roses, it is necessary to reduce the RH in the greenhouse using a dehumidifier, etc. By reducing the lowest daily RH by 10% through dehumidification, it is possible to reduce the loss of water per cut flower by up to 50%. As a result, the vase life of the cut flower can be extended by 2 days.
○ The export environment condition to maximize the vase life of the cut ‘Lovely Lydia’ roses, the temperature of the auction house should be no more than 10 ℃, while the RH of the logistics center should range from 70% to 80%. The VPD of the auction house should be no more than 0.5kPa. The vase life in the local market after exportation is highly influenced by the potential vase of the cut flowers at the time of harvesting. Therefore, it is essential to produce cut flowers of longer potential vase life (10 to 17 days).
○ As for the conditions for post-harvest management in order to maximize the vase life of the cut roses for export, the harvesting method should be web harvesting in the second stage, and the conditions for moisturizing and pre-treatment should be ClO2 (0.25ml/L), Chrysal RVB(2mL/L), and FloraLife Rose 100(1mL/L). The transportation method should be wet transportation method under in a temperature less than 4℃. The temperature in the screening house should be less than 15℃, while the temperature in the storage should be less than 4℃. The moisturizing solution treatment should be performed using Vital oxide (0.002mL/L), Chrysal Professional 2(5mL/L), and FloraLife Clear Rose 200 (10mL/L), which can contribute to an extended vase life during the exportation process.
2) Development of field application model and technology for freshness maintenance by production stage and distribution stage after harvesting in cut chrysanthemum
○ The cut chrysanthemum is damaged by high temperature if the day temperature exceeds 30℃, so day temperature should be controlled at 22~25℃.
○ When the temperature is lower than 13 ℃ at night, symptoms such as stem browning and growth inhibition occur. Therefore, night temperature should be maintained at 14 ~ 18 ℃
○ If the relative humidity at night is 80 ~ 90%or more, white rust disease will occur. And if the relative humidity is lower than 60%, it will cause problems such as poor growth and cut flower life. Therefore, it is suitable to keep the relative humidity at 70~80%.
○ When vapor pressure deficit is over 1.0 kPa or below 0.2 kPa in greenhouse, the growth of cut chrysanthemum is poor. Therefore, it should be managed to maintain 0.4~0.8 kPa.
○ If temperature of 5~10℃ is kept before sorting after harvesting of cut chrysanthemum, the quality of cut flower is improved by 10% and the vase life of cut flower is prolonged by 10% compared with 25℃ condition in grading room.
○ During the summer and winter season, the longer the time to leave at high temperature after harvest, the shorter vase life of cut flower in chrysanthemum.
○ Selection using automatic mass sorter rather than manual work improves the uniformity of cut quality and shortened the work time by 1/3.
○ After harvesting, wet forced-air precooling at 5 ℃ improved the vase life of 'Iwanohakusen' by 20%, ‘Baekma’ by 13%, and ‘Jinba’ by 14%. And, treatment of 100~200 mg·L-1 NaOCl as pretreatment solution increases the vase life by 10~17%.
○ The storage at 5℃ and 80~90% relative humidity after harvesting improves the quality and vase life of cut flower.
○ The longer the storage period in cold storage after precooling, the lower the cut flower life. After forced-air precooling treatment at 5℃ during 6 hrs, shipment for export should be done in short time to improve the quality and vase life of cut flower.
3) Development and Commercial Application of Optimal Cultivation and Post-harvest Management Technology for Exported Cut Lilies
○ For summer cultivation, we recommend temperature of 10℃ as lowest optimum temperature, contrary to the conventional recommendation of below 5℃, In addition, we suggest maintaining relative humidity at 70-80% level, higher than the conventionally recommended level of 50-60%, considering VPD and dew point. It is expected that these measures would amend low-humidity conditions within greenhouse and thus increase the potential vase life of the produced lilies for 2-3 days. The level of relative humidity was within the range of 71.0-86.5% in all test beds, which was deemed to be in optimal range. The quality of the cut lilies was somewhat higher in Jeju area compared to Seosan area, but no statistically significant difference was observed in vase life between regions.
○ There is a need to adequately adjust transportation conditions during exportation process in order to maximize the quality and vase life of cut lilies. For various stages of exportation, it was found that the optimal storage and transportation temperature was below 6℃ for low temperature storage in wholesale/retail markets, 6℃ during domestic transportation, and below 5℃ in auction sites. The optimal duration of exportation process was 4 days, and ideal duration at shelf in retail was within 3-5 days. Considering that the consumers expect at least 5 days of vase life for the lilies, at least 14 days of post-harvest life must be secured, and it must be ensured that the exported flowers have at least 10-12 days of potential vase life at retail stage.
○ To ensure maximum vase-life of cut Oriental lilies, the lilies must be harvested when buds are at developmental stage 1, and harvested and stored wet. For pulsing after harvest, using floral preservative was found to be beneficial compared to using plain water, and 10 hours of pulsing using only Chrysal SVB was found to be effective enough. After pulsing, the flowers must be stored and transported under temperature below 6℃. While the use of floral preservative was found to be effective in extending vase life when the flowers were wet transported, the effect of floral preservative comparatively diminished when the flowers were dry transported.
4) Development and application of distribution package and export package in flower using MEFI technology
○ In order to construct a test environment for the construction of a packaged environment using the wavelength of light of a cut flower, the construction of a test bed for LED illumination and the ease of floriculture experiment with electrical equipment In order to find out the conditions for optimizing the wavelengths used in the experiment with the test equipment, it was increased by application to the cut flower flowers of the radio wave led to UV by Green. And applied to the field.
○ As a result of applying MEFI technology to maintain and improve the freshness of the flowering of chrysanthemum and chrysanthemum, it has been found that in the case of the barbara, the flower scars, flower flue dryness, The flowering is displayed on the whole, and the flow of the flow is progressing on the first floor. The behavior of the cotomonic curve is slow and the flower is fully opened. Mucholina The coronary artery time is longer than that of the existing freshness retention technology. In the case of RB treatment, the amount of increase in the image width is small, and the increase value of the RB treatment is relatively uniform. In the initial stages after harvesting during marketing Within 3 to 5 days after the sale), RB products that have lost the early flowering at the time of sale are rich in flowers for the final consumer, and the dryness of the leaves is the slowest at the end. Marketability of attaching and distributing products In the case of Yuri, the condition in which the initial flowering proceeds most slowly is the B + UV treatment condition, and the condition in which the yellowing phenomenon occurs the slowest and the flower life is the longest is the R + UV treatment It was a condition.
○ As a result of the experiment on the exporting of Japanese export roses (Rosa hybrida L.'Lovely Lydia) for the analysis of the expression gene analysis and the certification test for the explanation of the scientific mechanism of the MEFI freshness retention technology, This paper presents a scientific basis for the MEFI technology, which shows that the expression level of the MEFI technique is different between the treatment and the samples of the MEFI treatment group, and that UP / DOWN is actually present in the genes involved in the aging mechanism It was possible to confirm
○ It is also possible to use export-oriented packaging products that are integrated with existing domestic technologies, functional materials such as ClO2 and ethylene sorbent for field application, and products suitable for each item, such as barra, chrysanthemum, We developed the final project type 3 type of "MEFI Function Module" to select the wavelength and install it in the export foil distribution package.
○ Developed for each year, the export test of the project type is applied seven times (six times in Japan, one time in China). The progress of the disposal is improved by the type of the barra, chrysanthemum and yuri, the test of the optimal wavelength type, The use of ethylene adsorbents for integration with domestic technologies and the use of ClO2 for pest and disease prevention and the wet system for export are optimized for their floristic characteristics during export We have conducted on-site testing of the development of the prototype.
○ We began our efforts to commercialize the MEFI PROTOTYPE system, which was proven to be effective in the field test of the export environment. At the Osaka-Daejeon export consultation meeting held in Osaka, Japan from July 6-8, 2017, the actual competition And the first export contract of $ 40,000 and has been successfully commercialized successfully at the ongoing stage in response to a request from the two companies for sample testing from the current two companies.
