심비디움의 재배연령과 화분크기에 따른 절화의 수량과 품질

국문 초록 (Abstract)

본 연구는 심비디움의 재배연령과 화분크기에 따른 절화 생 산량과 개화품질을 평가하고자 하였다. 대륜의 노란화색을 가 지는 심비디움 ‘Golden Tiara’ 품종을 실험재료로 사용하였으 며, 재배연차가 3, 4, 5년차로 증가함에 따른 절화 수확량과 특성을 비교하였다. 절화 수확량은 연차가 증가함에 따라 화 서수가 증가하여 5년차에 3년차에 대비 약 2배 증가하였다. 5 년차에서 화서 길이가 40cm미만으로 상품성이 없는 화서도 있었으나 이를 제외하고도 절화 수량이 가장 많았다. 개화소 요일수는 5년차에서 3년차보다 6일 정도 지연되었고 꽃크기 가 5년차에서 3, 4년차보다 감소하는 결과를 보였지만, 절화 품질의 주요인인 화서 길이와 화수는 연차에 따른 차이가 나 타나지 않았다. 관행의 직경 12cm화분과 직경 22cm의 대형 화분에서 재배하여 4년차 식물체의 개화특성을 비교한 결과, 화서의 길이와 꽃크기가 직경 12cm분에서 보다 대형화분에 재배하였을 때 증가한 것을 알 수 있었다. 따라서 심비디움 ‘Golden Tiara’ 품종의 경우 최소 5년까지 절화 수확이 가능한 것으로 판단되며, 이때 관행화분을 지속적으로 이용하는 것 보다 큰 화분으로 분갈이하여 줌으로써 생산성과 품질을 높일 수 있을 것으로 생각된다.

Cut flower yield and quality of Cymbidium ‘Golden Tiara’ were investigated depending on cultivation periods with 3, 4, and 5-year-old plants. Inflorescence number increased in response to increased cultivation periods. The inflorescence number was twice in 5-year-old Cymbidium compared with 3-year-old plants. No significant differences in inflorescence length and flower number were showed depending on cultivation periods. Flowering was delayed by 6 days in 5-year-old plants compared with 3-year-old plants. 4-year-old Cymbidium was grown in 12 and 22 cm pots containing 100% bark. Inflorescence length and flower size were longer in the plants grown in 22 cm pots than those grown in 12 cm pots. These results indicate that cut flowers of Cymbidium can be produced at least 5 years without significantly reduction in flower quality and larger pots could increase long-term productivity by enhancing flower quality of Cymbidium for subsequent cut flower production.
