재배시설 환경관리에 따른 국내육성 스프레이 장미 절화 생산성

국문 초록 (Abstract)

국내육성 스프레이 장미 품종의 농가 보급 확대와 수출 상품성 향상을 위해 PE 비닐하우스와 유리온실, 두 재배시설 환경관리에 따른 절화품질 및 절화 생산 성을 조사하였다. 재배시설에 따른 기상환경을 조사한 결과, 시간당 적산 일사량, 최고온도 및 습도, 변이(최 고값-최저값) 정도가 유리온실보다 PE 비닐하우스에서 높았다. 절화장은 시험품종 모두 유리온실에서 컸고, 줄 기 굵기와 소화수는 품종에 따른 차이는 있었으나 대 체로 PE 비닐하우스에서 우수하였으며, 분화된 총 분 지수와 수출 상품량은 적산 일사량이 높은 PE 비닐하 우스에서 많았다. 한편 흰가루병, 노균병, 잿빛곰팡이병 은 대기습도가 높게 관리되었던 PE 비닐하우스에서 발 생이 많았다. 따라서 스프레이 장미 수출 상품성 향상 을 위해서는 품종 특성 발현이 될 수 있도록 충분한 일사량, 대기온도 및 습도 등 재배환경 관리가 무엇보 다도 중요하였다.

This study was carried out to investigate the effect of environments in cultivation facilities (glasshouse or polyethylene vinyl house) in terms of flower productivity of the new bred spray roses cultivars in Korea. As result of investigating the environmental condition according to cultivation facilities, integrated solar radiation, maximum air temperature, relative humidity, and degree of their variation were the key factor in polyethylene vinyl house than those of glasshouse. Cut flower length of all cultivars used in this experiment were higher in glasshouse than in polyethylene vinyl house, however, stem diameter and floret number of most cultivars were increased in polyethylene vinyl house. Total differentiated shoot number and exporting marketable yield were higher in polyethylene vinyl house highly managed the total integrated solar radiation. Meanwhile, powdery mildew, downy mildew, and grey mold were easily infected in polyethylene vinyl house due to high air humidity. Therefore it was recognized as more important to suitably manage the environmental conditions such as solar radiation, air temperature and relative humidity fitted to cultivar characteristics to promote cut flower quality and exporting marketable yield above everything else.
