본 시험은 시설내에서 미스티블루 재배시 잡초의 발생을 억제하고 절화의 품질을 향상시키고자 피복재료(볏짚, 투명 polyethylene film 및 흑색 polyethylene film)를 공시하여 그 효과를 구명하고자 실시하였는데 지온의 변화를 4월부터 10월까지 조사한 결과 볏짚피복한 것과 흑색비닐 피복한 것은 온도 상승과 하강이 완만하였으나 투명비닐과 무피복구는 온도 변화가 심하였다. 고온기인 7월과 8월의 지온은 무피복구와 투명비닐피복구가 3℃ 이상 높았다. 피복재료별 잡초발생량은 흑색비닐 피복구가 타피복구나 무피복구에 비해 현저히 적어 잡초발생억제 효과가 큰 것으로 나타났다. 피복처리별 초기의 생육상황을 조사한 결과 흑색비닐피복구가 초장에서 약간 양호하였으나 엽장 등 생육은 큰 차이가 없었다. 화수폭, 화경경, 절화장 및 절화중 등은 흑색비닐피복구가 타처리구에 비해 양호하여 절화품질이 우수한 것으로 나타났다. 피복재료별 1등급 절화비율과 상품화율도 흑색비닐피복구가 90.5%와 81.8%로서 타처리구에 비해 양호한 것으로 나타났다.

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’.

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.

우리나라 화훼산업은 국민 생할수준 향상과 더불어 많은 발전을 거듭해 왔으나 다른 선진국들에 비하여 국민소득 대비 화훼 이용금액이 가장 낮은 국가로 보고되고 있다. 우리나라 화훼이용형태가 결혼식, 장례식, 이벤트 행사등과 같은 일시적 용도인 특수소비가 많은 비중을 차지하고 있으며, 이는 꽃을 주로 경조사나 특별한 기념일에만 주고 받는 선물용으로 생각하는 우리나라 국민의 문화정서 때문으로 파악 된다. 선진국과 같이 정서함양을 목적으로 하는 일반소비에 대한 비중을 높이기위해 화훼에 대한 인식변화와 더불어 구매자의 기호를 파 악하고 화훼상품의 질적인 변화를 꾀해야한다. 대학가의 플라워샵을 방문하는 고객의 주된 연령대는 20대로 남녀비율이 비슷한데 다른 지 역에 비해 남성비율이 높은 것은 선물용구입이 많고, 주 고객의 연령대는 20-30대 젊은 층으로 계속 증가하고 있다, 젊은 여성뿐만 아니라 젊은 남성도 주요한 화훼소비자가 될 가능성이 있으며, 그 선물의 대상이 될 젊은 여성들의 절화에 대한 선호도를 파악하여 화훼상품의 다 양한 개발에 필요한 정보를 알아보고자 서울 성북구 관내 여대생 103명을 대상으로 조사를 실시하였다. 상위 절화선호도는 장미(14.6%), 라넌큐러스(10.4%), 안개꽃(10%), 수국(9.4%), 아스틸베(9.1%), 프리지아(7.4%), 천일홍(4.5%), 해바 라기(4.2%), 델피늄(2.9%), 튤립/백합(2,6%)등이며 색상선호도는 분홍(21.7%), 빨강(18.7%), 노랑(18%), 흰색(17.5%), 보라(16.2%),초 록(7.4%), 기타(하늘색, mix color)순으로 밝고 따뜻한 색채에 높은 반응을 보였다. 꽃의 형태는 꽃다발(76.7%)을 가장 선호하며 그 다음으 로 한송이 포장(12.6%), 꽃바구니(4.9%), 꽃박스(4.9%)를 선택하였다. 미래 화훼산업의 주고객인 젊은층이 선호하는 취향과 요구에 맞는 절화 상품의 개발로 만족감을 높여 절화를 일상생활에서 즐길 줄 아는 소비자가 되고 절화시장의 활성화도 기대해 본다

This study was carried out to examine the effects of NaOCl, sucrose, and BA concentration as pretreatment solution on quality and vase life of cut flowers in Dendranthema grandiflorum ‘Jinba’. Flower diameter, fresh weight, and vase life in control and 0 mg･L -1 NaOCl treatments decreased, and the treatment with 100~200 mg･L -1 NaOCl was more effective in the quality and vase life. In pretreatment with 2.5% sucrose solution, flower diameter and fresh weight decreased and vase life was shortest due to the rapid leaf wilting. However, pretreatment with 0.1% sucrose solution increased the flower diameter and fresh weight, and showed the longest vase life. When more than 80 mg･L -1 BA was treated with pretreatment solution, flower diameter and fresh weight decreased, and vase life was shortened. With pretreatment of 20 mg･L -1 BA, the flower diameter was bigger than in the other treatments, but it was no effect on fresh weight and vase life. Therefore, it was suggested that pretreatment solution mixed with 200 mg･L -1 NaOCl, 0.1% sucrose, and 20 mg･L -1 BA was the most effective for the quality and vase life of cut flowers in standard chrysanthemum ‘Jinba’.

This study was conducted to know the visual preference and emotional change for the cut-flower decoration at public indoor space by using vertical, horizontal, and round type which are generally used. The investigation was done with 173 participants of National Institute of Horticultural and Herbal Science in 3 indoor areas designed with cut-flower decoration and 1 area of public place without it, respectively. Psychological evaluation was analyzed with the visual preference of cut flower shape and Semantic Differential method. In addition, the general awareness, loyalty and importance for cut-flower decoration were investigated. Statistical analysis was carried out with paired t-test, one-way ANOVA, cross correlation analysis, and analysis of frequency. As the result of evaluating the emotion of subjects with Semantic Differential, the feeling of comfort, nature and calm were significantly high in the public indoor space with cut-flower decoration. When we surveyed the feeling for the 3 type of cut-flower decoration with 14 pairs of emotional vocabulary, the participants felt ‘tranquil’ and ‘comfortable’ in the public indoor space with horizontal and round shaped decoration while they felt ‘strong’ and ‘anxious’ in the space with vertical shaped decoration. The preference of decoration forms was significantly high with round > horizontal > vertical type in order and vertical shape was highly preferred in twenties and sixties groups compared to other types significantly. In conclusion, we could recommend that round type decoration can be used in indoor place where comfort and calm are required and vertical form will be appropriate for challenging and vibrant twenties and depressed sixties with ageing. This customized cut-flower decoration will improve the environment quality of employment.

The measurement of psychological condition was carried out and compared with an attention recovery scale, profile of mood states (POMS) and semantic differential (SD method). In addition, paired t-test, One way ANAVA and Pearson’s correlation analysis were used for the statistical analysis. As the result of investigation for the general awareness of cut-flower decoration, the most priority is its color tone and 57.3% of participants which is the highest portion answered that the amount of annual investment for cut-flower decoration is 20,000～99,000 Won. According to the result of comparison for three psychological indexes, the attention recovery scale was significantly higher in the area with cut-flower decoration than the area without it. In POMS, it showed the negative emotions, such as, tension-anxiety, depression, confusion was low while the positive emotion like vigor was significantly higher in the area with cut-flower decoration than the area without it. In addition, the participants could feel the pleasant, natural and clam significantly more in the conference place with cut-flower decoration than the area without it. The order of color preference of cut-flower was Green > White > Pink > Blue > Yellow > Purple > Orange > Red with significant difference. Also, as the result of investigation for the color sensibility of its tone of the cut-flower decoration in conference place with SD method, the participants could feel ‘comfortable’ and ‘calm’ the most with green, white and blue decoration while ‘strong’, ‘vibrant’, ‘uneasy’ of feeling was shown the most in red and orange decoration and ‘warm’, ‘fancy’ in yellow. Based on the result of this study, the workers can have positive psychological effects by having cut-flower decoration or using appropriate colors with cut-flower decoration in the uncomfortable area, such as, conference place.

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’.

절화 백합‘Siberia’의 수확 후 수명 연장과 품질 향상을 위해 1-MCP의 효과적인 처리 농도, 시간 및 온도를 구명하기 위해 수행하였다. 개화 단계는 모든 처리별 5°C처리가 개화지연 효과가 가장 좋았으며, 특히 5°C조건에서 1.5mg·L-1 1-MCP를 1시간 처리시 다른 처리구에 비해 개화 단계가 지연되었다. 잎의 엽록소 함량은 모든 처리구가 대조구보다 다소 높은 엽록소 함량을 유지하였으며, 5°C조건에서 1.5mg·L-1 1-MCP를 1시간 처리시 높은 함량을 나타내었다. 생체중은 대조구가 5일부터 감소되는 반면 5°C 조건에서 1.5mg·L-1 1-MCP 전처리를 1시간동안 하였을 때 11일까지 증가되었다. 수분흡수량에서는 대조구가 실험 종료일까지 꾸준하게 감소하는 반면 15°C조건에서 3.0mg·L-1 1-MCP를 0.5시간 처리시 가장 높은 흡수량을 나타내었다. 수분균형은 무처리시 7일부터 (-)값으로 급격히 떨어지는데 비해 대부분의 1-MCP 처리구는 9일부터 서서히 (-)값으로 떨어지고, 특히 5°C조건에서 1.5mg·L-1 1-MCP 1시간 처리구는 11일까지 유일하게 (+)값을 유지하는 결과를 나타내었다. 각 전처리별 조사 초기 색상 변화에서는 5°C조건에서 3.0mg·L-1 1-MCP를 0.5시간 처리시 녹색값이 비교적 높게 유지되었으며, 절화수명 및 절화 품질에 있어서는 5°C조건에서 1.5mg·L-1 1-MCP를 1시간 처리시 19일로 가장 연장되는 효과를 나타내었다. 박테리아 발생량은 5°C조건에서 1.5와 3.0mg·L-1 1-MCP를 1시간 처리시 가장 낮은 발생량을 나타내었다. 에틸렌 발생량 및 호흡률은 대조구보다 낮은 발생량을 나타내었으며, 특히 15°C조건에서 3.0mg·L-1 1-MCP를 1시간 처리시 다른 처리에 비해 낮은 양상을 나타내었다. 이상의 결과를 종합적으로 고찰해보면 5°C조건에서 1.5mg·L-1 1-MCP를 1시간 처리시 도관의 미생물 발생 억제 효과가 지속적으로 작용하여 수분 흡수가 원활히 이루어짐으로써 수확 후 절화 백합의 선도유지 및 품질에 매우 효과적임을 알 수 있었고, 수출저장유통 과정 중에 상용적인 기술로 사용 가능함을 제시 할 수 있었다.
