Ⅳ. 연구개발결과
○ 1세부과제명 : 수출나리 억제재배시 싹틔우기와 생육단계별 영양 공급량 조절에 의한 고품질 절화생산 기술 개발
수출용 오리엔탈나리 ‘시베리아’의 여름철 고랭지 절화품질을 높이기 위하여 4단계의 대형 구근을 이용하여 정식 전 싹틔우기 처리로 시험한 결과, 작은 구근일수록 저온 싹틔우기 기간이 짧은 처리가 효과적이었으며, 구근 크기가 클수록 기간이 길 때 효과적이었다. 구주 18cm에서는 2℃ 0일 +5℃ 7일 + 12℃ 14일, 구주 20cm에서는 2℃ 7일 + 5℃ 7-14일 + 12℃ 14일, 구주 22cm에서는 2℃ 14일 + 5℃ 14일 + 12℃ 14일과 2℃ 21일 + 5℃ 7일 + 12℃ 14일, 구주 24cm에서는 2℃ 14-21일 +5℃ 7일 + 12℃ 14일 처리했을 때 절화장이 크고, 화수장 비율이 25-27%로 양호하였다. 수확소요일은 약 10일 더 빨랐고, 꽃 수는 1개 감소하였고, 블라인드는 0%, 절화등급은 2.2 ~ b1.0로 절화 품질이 향상되는 효과를 나타냈다.
오리엔탈나리 ‘시베리아’ 상자재배시 적정 배양액 조성 비율은 질산칼륨량이 1.5배 증가된 처리에서 절화장, 화뢰장과 화폭이 가장 길고, 엽록소 함량이 많아 가장 우수하였다. 오리엔탈나리 고온기 상자재배시 양액 관수량은 정식 후 6주간 2주마다 2L 처리(2-2-2L)에서 초장신장, 화수장과 화뢰폭이 컸으며, 절화중도 무겁고 꽃수도 많아 양호하였다.
○ 2협동과제명 : 수출용 나리 절화의 수확 및 유통과정의 품질 유지 기술개발
나리 절화 ‘Siberia’의 엽황화 경감을 위한 전처리로 1ml․L-1 Promalin에 3시간동안 침지 전처리 시 엽황화 현상이 크게 경감 되었으며, 전처리시 분무처리보다는 침지처리가 엽황화 경감 효과가 더 컸다.
작형별 나리 절화의 수송 온도로 ‘시베리아’는 여름과 겨울 작형 모두 수송온도 5℃에서 절화 수명이 가장 길었으며, 각 소화의 수명은 여름 작형이 겨울 작형보다 약 1~3일정도 길었다. ‘메두사’는 여름 작형은 15℃이하, 겨울 작형은 10℃이하로 수송시 전체 절화 수명이 길게 유지되었다.
저장기간과 저장 온도가 오리엔탈 나리 ‘소르본느’의 개화 특성으로 수송 온도 10℃ 이상, 4일 이상 저장시 비정상 개화 발생하였다. 저장기간과 저장 온도가 오리엔탈 나리 ‘소르본느’의 절화 수명에 미치는 영향으로 나리 절화 ‘소르본느’는 2~5℃에 저장하는 것이 품질 유지에 효과적이며 특히 장기저장에서 효과적이었으며, 저장시 10℃ 이하로 저장하며 절화 품질 유지를 위해 8일 이상 저장하지 않도록 한다

Two experiments were conducted to development of techniques for diagnosis of nutrient condition, prescription and improvement of post harvest cult flower quality of Lilium hybrids for export. The results are as follows.
1. Development of techniques for diagnosis of nutrient condition and pecription of cut flower quality of Lilium hybrids for export
Three pre-shooting temperatures and four durations on four bulb sizes before planting bulbs were studied in an effort to improve quality of Lilium Oriental Hybrid' Siberia'. For pre-shooting, bulbs were held at 2, 5 and 12°C, for 0, 7, 14, or 21 days before planting in Gangneung (a high land, 600m above sea level). In bulb circumference 18 cm, holding at 5°C for 7 days and 12°C for 14 days before planting resulted in increased the length and weight of harvested stems, reduced physiological flower bud blindness by 0%, shortened days to harvest by 10 days as compared with controls, and showed 2.2 of cut flower grade. In bulb circumference 20 cm, holding at 2°C for 14 days, 5°C for 14 days and 12°C for 14 days and 2°C for 21 days, 5°C for 7 days and 12°C for 14 days before planting resulted in increased the length and weight of harvested stems, reduced physiological flower bud blindness by 0%, shortened days to harvest by 10 days as compared with controls, and showed 1.7 and 1.8 of cut flower grade. In bulb circumference 22 cm, holding at 2°C for 7 days, 5°C for 7 to 14 days and 12°C for 14 days before planting resulted in increased the length and weight of harvested stems, showed 25.7~27.4% ratio of flower stalk per stem length, reduced the number of flower by 1.3, reduced physiological flower bud blindness by 0%, shortened days to harvest by 10-12 days as compared with controls, and showed 1.6 and 1.8 of cut flower grade. In bulb circumference 24 cm, holding at 2°C for 14 to 21 days, 5°C for 7 days and 12°C for 14 days before planting resulted in increased the length and weight of harvested stems, showed 26.4~26.9% ratio of flower stalk per stem length, reduced the number of flower by 1.0, reduced physiological flower bud blindness by 0%, shortened days to harvest by 10-11 days as compared with controls, and showed 1.0 and 1.2 of cut flower grade. Therefore in order to produce cut flower of Lilium Oriental Hybrids with big bulbs during high temperature season in high land, pre-shooting before planting was effective to reduce physiological disorder, shortened days to harvest by 10-12 days, showed 25~27% ratio of flower stalk per stem length, and improve cut flower quality by 1-2 grade compared with controls. Nutrition solution rate of Lilium Oriental Hybrid' Siberia' was effective in 1.5 times potasium nitrate. The cut flower length, flower length and flower width were the most, and its chlrolopyll content was the best. Nutrition solution watering amount of Lilium Oriental Hybrid' Siberia' was effective in watering 2L every weeks for 6 weeks. The cut flower length, flower length and flower width were the most, its flower weight was the heaviest, and the number of flower was the most.
2. Development of techniques for improvement and maintain of post harvest cut flower quality of Lilium hybrids for export
This study was conducted to investigate the effects of pre-treatment solution, holding solution, shipping, storage method, and cultivation period for extension of vase life and improvement of quality in cut lily. Cut lilies were treated with various temperature (2, 5, 15, 25℃) for 5 days. When cut lilies were stored at 2 and 5℃, vase life and quality of 1st and 2nd floret were improved however, significantly decreased at 25οC. In ‘Casa Blanca’ and ‘Siberia’, the vase life of 1st floret stored at 5℃ was increased about 1.5 days than at 15℃. The vase life of all three varieties was decreased by the storage of at 2℃ as compared to 5℃, particularly decreased 1.6 days in ‘Casa Blanca’. Therefore, The cut ‘Casa Blanca’ and ‘Siberia’ lilies for exporting was considered storage at 5℃. Moreover, the cut ‘Medusa’ lilies were considered storage at 15℃. The period of cultivation affect the vase life of cut lily. Total vase life of winter period cultivation was longer than summer period cultivation. Storage temperature below 15℃ in summer period cultivation and below 5℃in winter period cultivation increased vase life of cut lily ‘Siberia’. Storage temperature below 15℃ in summer period cultivation and below 10℃in winter period cultivation increased vase life of cut lily ‘Sorbonne’.The shipping temperature of above 25 ℃ induced wilting of 1st and 2nd floret. Characteristics of flower between summer period cultivation and summer period cultivation had no significant differed. When cut lilies were stored at 15℃ for 10 days, vase life of cut lily ‘Sorbonne’ decreased 4 days and ‘Siberia’ decreased 6 days compared with 5℃ for 10 days. The long term storage temperatures for improve quality of cut lily are 2∼5℃for ‘Sorbonne’ and 5∼10℃ for ‘Siberia’. Under high temperature and long storage, quality of cut lily decreased. The diameter of 1st floret was largest in ‘Sorbonne’ under 2℃. Storage temperature and period affect less diameter of ‘Siberia’ floret than ‘Sorbonne’. The fresh weight of cut lily decreased under 15℃. According to temperature, the period of fresh weight maintained highly were 6 days in ‘Sorbonne’ and 9 days in ‘Siberia’. Under 2∼5℃, the fresh weights of cut lily were maintained for long period. Pretreatment of S+AsA+GA and Promalin extended vase life of cut lilies. In pretreatment of S+AsA+GA, diameter of ‘Sorbonne’ 1st floret increased 6cm, ‘Siberia’ increased 2cm.
