초록

본 연구는 두 품종의 장미 삽목묘의 묘령에 따른 생장과 수량에 미치는 영향을 조사하고 국내 육성 절화장미의 효과적인 삽목번식법을 개발하고자 수행하였다. 장미는 스탠다드 계통인 'Pink Aurora'와 스프레이 계통인 'Yellow King' 품종을 사용하였다. 삽수는 5매엽을 사용하였고 서로 다른 날짜에 암면큐브($5cm{\times}5cm{\times}5cm$, UR, 한국)에 삽목하였다. 2009년 1월 20일에 삽목하여 30일이 경과한 삽목묘와 2009년 1월 2일에 삽목하여 48일이 경과한 묘를 사용하여 2009년 4월 18일에 암면슬래브($10cm{\times}15cm{\times}100cm$, UR, 한국)에 정식하였다. 2009년 1월부터 7월까지 재배하는 동안에 2번 수확하여 절화의 품질을 조사하였다. 정식전의 생육을 조사한 결과 48일이 경과한 묘는 두 품종 모두 신초와 뿌리가 생장하였다. 그러나 30일이 경과한 묘는 'Pink Aurora'의 경우 신초와 뿌리가 생장하지 않았고, 'Yellow King'은 신초는 생장하였고 뿌리는 생장하였으나 배지에서 육안으로 확인할 수 없었다. 이러한 결과로 'Yellow King'이 'Pink Aurora'보다 생장속도가 빠른 것으로 판단된다. 정식 후의 생장과 절화 수량은 스탠다드 계통인 'Pink Aurora'는 30일 경과한 묘보다 48일이 경과한 묘에서 수량이 더 많이 나타났지만, 평균 절화 생체중은 30일이 경과한 묘보다 작았다. 'Yellow King' 품종은 30일이 경과한 묘에서 절화장, 화폭, 5매엽수, 절화 생체중, 수량이 40일 경과한 묘보다 더 높았다. 'Pink Aurora' 품종은 48일이 경과한 묘에서 다른 처리에 비해 더 좋은 생육을 보였다. 'Yellow King' 품종은 뿌리의 상처가 작았던 30일이 경과한 묘에서 더 높은 수량을 보였다. 이러한 결과는 품종에 따른 성숙도의 차이로 판단되며 다양한 품종을 대상으로 한 실험이 필요하다고 생각된다.

This study was conducted to investigate the effect of age of transplants, propagated by cutting, of two cut rose (Rosa hybrida Hort.) cultivars on their subsequent growth and yield in an effort to develop an efficient cutting propagation method for domestic rose cultivars. Two cultivars used in this study were a standard type 'Pink Aurora' and a spray type 'Yellow King'. Cuttings were prepared as single node cuttings each with a five-leaflet leaf and were stuck in rockwool cubes ($5cm{\times}5cm{\times}5cm$, UR, Korea) at two different dates. Cuttings rooted for either 30 (stuck on Jan. 20, 2009) or 48 days (stuck on Jan. 2, 2009) were transplanted into a rockwool slabs ($10cm{\times}15cm{\times}100cm$, UR, Korea) on the same date, 18 Feb. 2009. Plant growth and cut flower quality were investigated for two successive harvests during the period of Jan. to July in 2009. In both cultivars, 48 days old plants showed some growth of the shoot and root before transplanting. However, in the case of 30 days old plants before transplanting no noticeable growth of the shoot and root was obserable in 'Pink Aurora', while only shoot growth, but not root growth to the bottom of the rooting medium, was observed in 'Yellow King'. This suggested cultivar-specific responses that in this experiment a spray type 'Yellow King' showed greater growth rate during the rooting stage than a standard type 'Pink Aurora'. In the measurement of growth and cut flower yield after transplanting, the 48 days old standard type 'Pink Aurora' produced greater number of cut flowers per plant than 30 days old plants, whereas their mean stem fresh weight was recorded smaller than that of the 30 days old plants. For 'Yellow King', 30 days old plants showed greater stem length, flower width, number of five-leaflet leaves per stem, stem fresh weight, and number of cut flowers per plant than 48 days old plants. Therefore, growth and yield were significantly affected by cultivar and age of the rooted cutting, and additional research is needed on the effect of age of rooted cuttings in more cultivars.
