노용승,In Kyung Kim,Yong Kweon Yoo 한국원예학회 2018 원예과학기술지 Vol.36 No.6

The objective of this study was to determine the effects of dry and wet conditions during harvest andshipping on the quality and vase life of cut flowers using the standard chrysanthemum cultivar‘Baekma’. Wet harvest and wet shipping (Wet-Wet) treatments maintained a high fresh weight ofcut flowers and extended their vase life by 2 days compared to dry harvest and shipping (Dry-Dry)treatments. However, no significant difference was observed in the quality or vase life of cutflowers between dry harvest and wet shipping (Dry-Wet) and Wet-Wet treatments. The Dry-Drytreatment also resulted in lower chlorophyll fluorescence ratios (Fv/Fm) than the Wet-Wet treatment,and it means Dry-Dry treatment had more stress than Wet-Wet treatment. We also tested the effectsof treatment with a wet shipping solution containing sodium hypochlorite (NaOCl) and chlorinedioxide (ClO2). When cut flowers were placed in a holding solution with NaOCl after transport,both fresh weights and flower diameters were highest when treated with 50-200 mg‧L-1 NaOCl. Treatment with a 50 mg‧L-1 NaOCl wet shipping solution also extended the vase life of cut flowersby 2 days compared to other shipping solutions. When cut flowers were transported with a 0.5-2 mg‧L-1ClO2 wet shipping solution, they maintained high quality with an extended vase life of 2.1 days. Treatment with either NaOCl or ClO2 shipping solution significantly inhibited bacterial growthafter transport for 4 days. These results suggest that standard chrysanthemum ‘Baekma’ should bedistributed in a wet shipping solution of 50 mg‧L-1 NaOCl or 0.5-1 mg‧L-1 ClO2 to maintain qualityand vase life of cut flowers exported to Japan.

노용승,유용권 한국화훼산업육성협회 2010 화훼연구 Vol.18 No.4

본 연구는 국화 ‘신마’ 품종의 플러그 묘 생산에 있어 서 삽수의 조건이 지상부 생육과 발근 및 정식 후의 절화 생육에 미치는 영향을 알아보고자 실시하였다. 삽수에 부착된 잎을 전부 제거한 처리는 지상부 생육이 가장 불량하였고, 전혀 발근이 안 되었다. 잎을 4~6개를 부 착하여 삽목하는 것이 지상부 생육 및 발근에 효과적 이었다. 삽수길이는 5~7 cm 처리에서 지상부의 무게가 무거웠으며, 발근에 있어서는 다른 처리에 비하여 5 cm 처리에서 뿌리의 무게가 가장 무거웠고, 뿌리수가 가장 많았다. 삽수 굵기가 굵을수록 지상부 생육과 발근이 양호하였다. 삽수에 부착된 엽수가 4~6개인 처리에서 절화장이 길었으며, 줄기의 굵기도 컸다. 삽수의 굵기가 3.2 mm 처리에서 절화장이 가장 길었다. 따라서 국화 ‘신마’ 플러그 묘 생산시 삽수의 굵기가 3.2mm 정도의 5cm 길이의 삽수에 4장의 잎을 부착하여 삽목하는 것이 묘의 생육 및 발근에 효과적이고, 정식 후 절화의 생 육에도 적합하였다. This study was carried out to examine the effect of cutting condition on rooting and their subsequent growth of cut flower in plug cutting of ‘Shinma’, one of autumn-flowering chrysanthemums. According to the results, cutting with four or six leaves was effective in shoot growth and rooting than any other treatments, and also the length and thickness of cut flower were increased. In case of cutting with leafless, it showed the poorest shoot growth among all of the treatments and there was no root. The weight of shoot was heavier than any other treatments in case of the length of cutting (5~7 cm). And the weight of root and its number were better than any other treatments, in treatment of the length of cutting (5 cm). The growth of shoot and rooting were enhanced by increasing the thickness of cutting. In case of thickness of cutting, the cutting (3.2 mm tnickenss) showed more favorable shoot length of cut flower than any other treatment. Therefore, it is recommended that the 5 cm long and 3.2 mm thick cuttings with four leaves are used to improve their rooting and subsequent growth in plug cutting of Dendranthema grandiflorum ‘Shinma’.

노용승,김인경,유용권 인간식물환경학회 2019 인간식물환경학회지 Vol.22 No.6

This study was conducted to examine the effects of wet storage solution, transport period and temperature on vase life and quality of cut flowers in standard chrysanthemum ‘Jinba’. Immediately after transport, the fresh weight and flower diameter of cut flowers did not show a difference according to wet storage solutions regardless of the transport period, but as the transport period increased, the fresh weight and flower diameter increased. The flower bud stage at harvest was maintained due to the small changes in flower diameter, and the freshness of leaves was better when transported at 5℃ than at 25℃. When transported at 25℃, the longer the transport period, the lower the quality of cut flowers as some petals opened up and showed early flowering after transport. In preservative solutions, quality of cut flowers transported at 25℃ was lower than that at 5℃ due to fresh weight and diameter according to the longer transport period. The vase life of cut flowers was 1.0 day, 0.8 day, and 7.3 days longer when transported for 3, 5, and 7 days respectively at 5℃ than at 25℃. The quality of cut flowers was better due to increase in fresh weight and flower diameter, as well as vase life in wet storage solutions of ClO2 and Chrysal OVB than in tap water, regardless of transport period and temperature. There was no difference in fresh weight and vase life between ClO2 and Chrysal OVB, but flower diameter was greater in ClO2 than in Chrysal OVB. Therefore, for long-term transport of cut standard chrysanthemum ‘Jinba’, wet storage transport in ClO2 at 5℃ was found effective in maintaining the quality and vase life of cut flowers.

노용승,김인경,유용권 인간식물환경학회 2017 인간식물환경학회지 Vol.20 No.4

This study was conducted to analyze the correlation between cultivation environment, cropping system, and the quality of cut flower in autumn-winter season chrysanthemum‘Jinba’, and to suggest the cultivation factors that can improve the quality of cut flower. It was examined for cultivation environment such as average day and night temperature, average day and night relative humidity, average day and night vapor pressure deficit (VPD), and integrated solar radiation of 4 farms planted in mid-October. Also, it was surveyed for cropping system such as cutting condition, growth period, irrigation method, soil chemical properties. Chrysanthemum ‘Jinba’ was harvested in order to investigate the quality of cutting of four farms, and then growth, chlorophyll content, and vase life of cut flowers were investigated. Based on these data, it was analyzed for the correlation between cultivation environment, cropping system, and quality of cut flower elements. In correlation between cultivation environment and quality of cut flower, the average night temperature showed a negative correlation with the growth of cut flower, and it was no correlation with other environmental factors. The vase life showed a negative correlation with the average day and night temperature and VPD, and a most positive correlation with the average day and night humidity. In correlation between cropping system and quality of cut flower, the cutting length, period of vegetative growth, daily irrigation amount, and total irrigation amount showed a less positive correlation, and leaf number of cutting and soil pH showed a most positive correlation with growth of cut flower. On the other hand, soil EC showed a less negative correlation, and days to flowering after light out showed a most negative correlation with growth of cut flower. The vase life of cut flower was not correlated with the cropping system factors.

노용승,김인경,유용권 인간식물환경학회 2017 인간식물환경학회지 Vol.20 No.5

This study was carried out to examine the effective wet harvesting solution for development of wet distribution system in standard chrysanthemum (Dendranthema grandiflorum) ‘Baekma’. The cut flowers were treated immediately in floral preservative solutions or dry condition after harvesting, and then the effects on quality of cut flower were compared. Also, we investigated the effects of NaOCl and sucrose on vase life and quality of cut flower. When the cut flowers were treated immediately in tap water, Chrysal OVB, Floralife, Hiflora solutions after harvesting, flower diameter and fresh weight of cut flower increased compared to dry condition treatment. In single treatment of 100 mg・L-1 NaOCl as wet harvesting solution, flower diameter and fresh weight of cut flower increased more than other treatments, and vase life was prolonged to 1.5 days than control. But, flower diameter and fresh weight of cut flower decreased in 0 or 200 mg・L-1 NaOCl. When the cut flowers were treated in combination solution of 100 mg・L-1 NaOCl and 0.1% sucrose, the flower diameter was the largest by 9.8 cm, and fresh weight of cut flower was maintained the highest in holding solution. On the other hand, flower diameter and fresh weight of cut flower were lowest in combination solution of 100 mg・L-1 NaOCl and 2.5% sucrose. There was no difference in vase life between treatments mixed with NaOCl and sucrose. Therefore, it was suggested that treatment mixed with 100 mg・L-1 NaOCl and 0.1% sucrose as wet harvesting solution was the most effective for vase life and quality of cut flower in standard chrysanthemum ‘Baekma’.

노용승,In Kyung Kim,유용권 한국원예학회 2020 원예과학기술지 Vol.38 No.2

This study was conducted to identify the effects of NaOCl, ClO2, and Chrysal OVB, which are thesolutions used for shipping, on the quality and vase life of chrysanthemum ‘Baekma’ cut flowers. We also aimed to analyze correlations with vase life by analyzing chlorophyll fluorescence andspectral reflectance of cut flowers subjected to dry and wet shipping. Compared to dry shipping, thewet shipping treatments using solutions of NaOCl, ClO2, and Chrysal OVB resulted in an increaseof fresh weight and flower width, with the leaves remaining in fresh states after transport for 4 days. In holding solution, the cut flowers transported with 50 mg·L-1 NaOCl had a greater fresh weightand flower diameter as well as a longer vase life of 26 days compared with dry and wet shippingconditions with tap water, ClO2, and Chrysal OVB solution. The cut flowers treated with wet shippingconditions by NaOCl had lower values of ABS/RC and DIo/RC and higher values of Fm/Fo, Fv/Fo,Fv/Fm, TRo/ABS, ETo/TRo, ETo/ABS, Pi_ABS, and ETo/RC among chlorophyll fluorescenceparameters compared to those subjected to dry shipping conditions. Among the parameters, theFv/Fm and ETo/RC exhibited statistically significant correlations with the vase life of cut flowers. In terms of spectral reflectance, the wet shipping treatment with 50 mg·L-1 NaOCl resulted in lowervalues of CRI, G, MCARI, NPCI, and SIPI that represent the ratio of contents of carotenoid andchlorophyll compared to the dry shipping treatment, whereas SRPI resulted in higher values. Amongthese parameters, the CRI, SRPI, and NPCI manifested a statistically significant correlation with vaselife of cut flowers. Therefore, it was concluded that wet shipping with 50 mg·L-1 NaOCl helpedmaintain quality and vase life of cut flowers of chrysanthemum ‘Baekma’ compared to dry or wetshipping with Chrysal OVB and ClO2 that were used commercially. In addition, the Fv/Fm andETo/RC, representing chlorophyll fluorescence, and CRI, SRPI, and NPCI, representing spectralreflectance, were found to be feasible indicators predicting the vase life of cut flowers.

국화 ‘백선’의 토양재배에서 관비주기와 시비량에 따른 절화의 생육과 토양 환경의 변화

노용승,유용권 한국인간식물환경학회 2016 인간식물환경학회지 Vol.19 No.3

This study was conducted to examine the effects of irrigation interval and fertilizer level on changes in soil chemical properties and growth of cut flower in soil retarding culture of standard chrysanthemum (Dendranthema grandiflorum) ‘Iwanohakusen'. The compound fertilizer (Poly-Feed, N-P-K 19-19-19) diluted with 1 g・L -1 were treated by irrigation intervals of 1 time/1 day (1.5 L・m -2 ), 1 time/2 days (1.5 L・m -2 ), 2 times/3 days (3 L・m -2 ) and 2 times/5 days (3 L・m -2 ). As irrigation interval was long, the nutrient contents of soil decreased. In 1 time/1 day treatment, NO3-N, K, and P2O5 contents of soil decreased, but Ca and Mg contents of soil did not change than before planting. The growth of cut flower, such as stem length, stem diameter, fresh weight, and weight of flower was the best in 1 time/1 day treatment, and was the worst in 2 times/5 days treatment. To examine the proper fertilizer level, the compound fertilizers (Poly-Feed, N-P-K 19-19-19) of 0.2, 0.4, 0.8, and 1.6 kg per 1.5t water were treated 1 time/1 day in 1,000 m 2 field. In fertilizer level of 0.8 or 1.6 kg, EC and nutrient contents of soil were higher or similar than before planting, and inorganic salts in soil were accumulating continuously. The growth of cut flower, such as stem length, number of leaves, weight, and diameter of flower bud was more effective in fertilizer level of 0.4 kg, but it was the worst in excessive fertilizer level of 1.6 kg. Therefore, fertigation of 0.4 kg compound fertilizer with 1 time/1 day in 1,000 m 2 field was the most effective for reasonable soil management and cut flower production of high quality in retarding culture of standard chrysanthemum ‘Iwanohakusen’.
