유용권(Yong Kweon Yoo),노용승(Yong Seung Roh) 인간식물환경학회 2013 인간식물환경학회지 Vol.16 No.5

This study was conducted to examine the effects of flowering stage after simulated shipping during 48hr at 20℃ on quality and senescence of cut flower in spray chrysanthemum ‘Lemon ND’(Dendranthema grandiflorum ‘Lemon ND’). Flower diameter of cut flower harvested in first or second stage was 10mm smaller than that harvested in fifth stage. Fresh weight of cut flower was light in fast flowering stage, and that of first stage was lighter by 13g than that of fifth stage at 2 days in holding solution. Cut flower of third stage absorbed the most solution, and Total solution uptake of flower in earlier and later stage than third stage decreased. The days to 50% senescence rate in fifth stage was the shortest, and vase life was 12.4 days. In cut flowers of earlier stage, days to 50% senescence rate and vase life were prolonged.

Improving the Quality of Cut Hydrangea Flowers on Treatments of CO₂ Fertilization under Pre-harvest and Slightly Acidic Electrolyzed (HOCl) Water under Postharvest

Hee Won Kim,Tae Ho Han,Young Boon Lee 한국원예학회 2023 원예과학기술지 Vol.41 No.1

This study investigates the effect of CO₂ fertilization before harvest using 800 ㏖·㏖<SUP>-1</SUP> from November 2021 to May 2022 and vase solution treatment using slightly acidic electrolyzed water (HOCl 5 μL·L<SUP>-1</SUP>, pH 5.0 – 6.5) after harvest of Hydrangea macrophylla ‘Moonstar’. The CO₂ fertilization + HOCl treatment was the longest extension of the vase life and the largest total vase solution uptake. The vase solution treatment of HOCl influenced the vase life to a greater extent than by CO₂ fertilization. In the CO₂ fertilization treatment, the HOCl treatment reduced the number of bacteria on the end of stems by 54% compared to that achieved without HOCl treatment. It was higher on the relatively fresh weight and vase solution uptake in CO₂ fertilization + HOCl treatment than that of control after 6 days of treatment. The CO₂ fertilization + TW or HOCl treatments maintained the initial fresh weight for up to 6 days after treatment. There was no difference in the ΔE value, and chlorophyll contents of leaves and flower size did not differ in all treatments. Therefore, the initial sterilization on the end of stems after harvest was an essential factor for improving the quality of cut hydrangea flowers. The vase solution treatment of HOCl 5 μL·L<SUP>-1</SUP> after harvest extended the vase life of cut hydrangea flowers.

Ju Hwi Kim,Young Boon Lee 한국화훼학회 2022 화훼연구 Vol.30 No.2

This study aims to investigate the proper mixing treatment concentration of ozone (O3) and sucrose to preserve and extend the vase life of the cut rose flowers ‘Dominica’. The vase solution was prepared using tap water, 3% sucrose, ozone 5.5 mg L-1, and 3% sucrose with ozone 5.5 mg L-1. The vase life was the highest in the tap water and ozone treatments at 16.3 and 16.1 days, respectively. The vase life of ozone with sucrose treatment was 6.9 days, which was 9.4 days lower than that of the control. Compared to a single treatment, the vase life termination symptoms for ozone with sucrose treatment decreased petal wilting and increased bent necks. Relative fresh weight and vase solution uptake increased up to 4 days after treatment and decreased from 2 days before vase life termination. The rate of change in petal color was high in L*, a*, and b* for the sucrose treatment than after harvest, and low for the ozone treatments. The maximum relative flower size increase rates after treatment were 195% in the control, 186% in the sucrose treatment, 171% in the ozone treatment, and 155% in the ozone with sucrose treatment.

최목필(Mok Pil Choi),이풍옥(Poong Ok Lee),김원희(Won Hee Kim) 한국원예학회 2013 원예과학기술지 Vol.31 No.5

This study was conducted to investigate optimal harvesting stage and the effects on cut roses of Korean cultivar harvested at different stages. Cut roses are harvested at three different flowering stages. The optimal harvesting stage of cut roses was different depending on varieties. The vase life of standard type ‘Pink Song’ and spray type ‘Peace One’ was extended when they were harvested in one and three stages, respectively. The vase life was generally increased when the cut roses were pretreated with a solution containing 2% sucrose + 200 mg?L<SUP>-1</SUP> aluminum sulfate + 200 mg?L<SUP>-1</SUP> Mg (NO₃)₂ + 50 mg?L<SUP>-1</SUP> CaCl₂ as compared to the control regardless of the harvesting stage. And this pretreatment solution improved the flower quality of cut roses bred in Korea. But the effects of pretreatment were varied depending on the harvesting stage.

수출 시 장미의 절화수명을 효과적으로 연장시켰던 친환경 살균물질인 ClO2의 적용 가능성과 수출 유통 환경분석을 위해 실험을 수행되었다. 일본 수출절화 장미 ‘Wildlook’의 수출유통단계에 따른 온・습도를 측정한 결과, 로즈피아 선별 및 포장 단계에서는 26~27℃/RH 40~43%, 로즈피아 저장고단계에서는 1~6℃/RH 35~64%, 부산 운송단계에서는 17~22℃/RH 48~73%, 일본 배 운송단계에서는 5~11℃/RH 54~70%, 일본경매장 및 소매점단계에서는 13~28℃/RH 46~81%로 총 5단계로 고온과 저온이 반복되었으며, 습도는 35%이상이었다. 각 단계별 평균 온・습도는 26.9℃/RH 41.6%, 2.3℃/RH 56.6%, 20. 3℃/RH 58.2%, 6.9℃/RH 65.6%, 23.9℃/RH 69.45%로, 고온과 저온이 반복되었고 습도는 지속적으로 높아졌다. 관행 수출방식(박스당 30송이, 절화 60cm) 절화에 물과 ClO2 5μL・L-1 약 800mL을 공선장 포장단계에서 보존용액 처리 후 소매점에서 절화수명실험을 한 결과, 절화수명은 물과 ClO2처리구에서 각각 12.6일, 11.6일로 유의차가 없었다. 결론적으로 장미는 수확 후 일본 수출 시 운송 3일 동안 고온과 저온이 반복되는 것을 알 수 있었으며, 습도는 운송시간이 경과 될수록 높아지는 것을 알 수 있었다. 또한 수출보존용액으로 ClO2를 처리하였지만 대조구와 차이가 없었으므로 수출 절화 장미의 보존용액 처리에 ClO2 적용을 위해서는 적정 농도를 찾는 연구가 필요할 것으로 판단된다. Our study analyzed the effect of chlorine dioxide (ClO2), an environmentally friendly disinfectant, and that of the export distribution environment on Japanese cut rose flowers. We measured the air temperature and relative humidity (RH) during flowers export, which was divided into five stages as follows: sorting and packing, 26 - 27℃/RH 40 - 43%; storage, 1 - 6℃/RH 35 - 64%; transport to Busan, 17 - 22℃/RH 48 - 73%; shipping to Japan, 5 - 11℃/RH 54 - 70%; and holding for sale in Japan's stores, 13 - 28℃/RH 46 - 81%. RH was consistently > 35%. The average air temperature and RH for each stage was 26.9℃/RH 41.6%, 2.3℃/RH 56.6%, 20.3℃/RH 58.2%, 6.9℃/RH 65.6%, and 23.9℃/RH 69.45%, respectively. The high and low temperatures varied, while RH was continuously high. The cut rose flowers (30- and 60 cm stems) were treated with either water (control) or 5 μL·L-1 ClO2 at the packing stage at a sorting facility, and a vase life test was conducted at a retail store in Japan. There was no significant difference in vase life between the stems treated with water and those treated with ClO2 after 12.6 and 11.6 days, respectively. We concluded that cut rose flowers are affected by varying high and low temperatures for 3 days during transport to Japan and by consistently high RH over time. It was necessary to find an appropriate concentration to apply ClO2 in processing export, because the vase solution treatment of ClO2 was no different to control.

수확 후 고효율 에너지 LED 광과 Azoxystrobin 처리에 대한 장미 ‘Bubble Gum’의 절화품질에 미치는 영향

박원희,조민경,김주희,이영분 한국화훼학회 2022 화훼연구 Vol.30 No.3

본 연구는 장미 ‘Bubble Gum’에 대한 수확 후 LED 광 환경과 살균제 Azoxystrobin 보존용액 처리 시 절화품질에 미치는영향을 구명하고자 수행되었다. 광은 백색 LED와 유색 LED (red:blue=5:1)로 처리하였고, 보존용액은 수돗물(tap water, TW)과 Azoxystrobin 0.05 mL・L-1를 처리하였다. 백색 LED처리의 절화수명은 TW, Azoxystrobin처리구 각각 9.6일, 9.7일로 LED 광과 보존용액 처리 간의 유의차가 없었다. 유색 LED 처리의 절화수명은 TW처리구가 13.6일, Azoxystrobin처리구가 9.8일로, 유색 LED 처리구가 대조구(백색 LED + TW)에비해 절화수명을 4일 연장시켰다. 절화수명 종료 증상은 LED 광 조건과 관계없이 Azoxystrobin처리구는 꽃잎 위조와 청변화 증상을 감소시켰다. 모든 처리구에서 상대생체중과 수분흡수율은 각각 처리 후 2일, 4일까지 증가하다 감소하는 경향을보였다. 수확 직후 대비 처리 6일 후 화색 변화율과 잎의 엽록소 함량은 수확 직후와 모든 처리구에서 차이가 없었으며, 화폭증가율도 처리 간 차이가 없었다. 결론적으로 백색 LED + Azoxystrobin 보존용액처리는 절화장미의 꽃잎 위조와 청변화증상을 감소시키지만, 절화수명 연장효과가 없었으며, 적색 + 청색 LED 처리는 장미의 절화수명 연장효과에 효과적이었다.
