Abstract

This study was conducted to investigate the effect of rooting volume on the productivity of fresh shoots when growing rosemary in multi-layer cultivation. The 10 cm middle cuttings from which the common rosemary (Rosmarinus officinalis L.) apical bud was removed were planted in a 128-hole tray, rooted, and then transplanted into pots of 125, 200, 550, 750, 1,300, and 2,000 mL to determine the growth characteristics and quantity of young shoots of 1-year-old and 2-year-old rosemary. In the case of 1-year-old rosemary, there was no clear difference in initial growth (30 days after transplanting) between treatments in pot size larger than 550 mL, in the case of 2-year-old rosemary, growth tend to be proportional as the pot became larger. The fresh weight of the underground part of 1-year-old and 2-year-old rosemary was the lowest at 6.9 g and 24.4 g, respectively, when surveyed on July 25 in a 550 mL container, and 10.3 g and 24.9 g, respectively, when surveyed on November 24, and there was a difference between treatments in containers of 750 to 2,000 mL. On the other hand, in the case of 1-year-old rosemary, the fresh weight of the above-ground part increased as the pot became larger, but there was no statistical difference above 1,300 mL, and the fresh weight of 2-year-old rosemary was also significantly higher as the pot became larger. The quality of young shoots was the best for 1-year-old rosemary in a pot of 2,000 mL, but for 2-year-old rosemary, there was a difference in quality depending on the season. Shoot productivity per unit pot was highest at 1,300 mL, but when converted to per unit area, the best was observed at 750 mL. Therefore, the most suitable pot size for intensive production through multi-layer cultivation of rosemary young shoots is judged to be 750 mL (12.5 × 11.5 cm).

본 연구는 로즈마리 다단재배 시 근권부 용적이 어린순 생산성에 미치는 영향을 구명하고자 수행되었다. 정아를 제거한 커먼 로즈마리의 중간부 삽수 10cm를 128공 트레이에 삽목하여 발근시킨뒤125, 200, 550, 750, 1,300 및 2,000mL의 용기에 이식하여 1, 2년생 삽목묘 어린순의 생육특성과 수량성을 비교하였다. 1년생 로즈마리의 경우 초기 생육(이식 후 30일)은 용기 550mL 이상에서 처리 간 뚜렷한 차이가 없었으나, 2년생 로즈마리의 경우 용기가 클수록 생육이 비례하는 경향을 보였다. 1, 2년생 로즈마리의 지하부 생체중은 용기 550mL에서 7월 25일 조사 시 각각6.9g, 24.4g, 11월 24일 조사 시 각각10.3g, 24.9g으로 가장 낮았고, 용기 750-2,000mL에서는 처리 간 차이가 보이지 않았다. 반면 지상부 생체중은 1년생 로즈마리의 경우 용기가 클수록 증가하다가 1,300mL 이상에서는 통계적 차이가 없었으며, 2년생 로즈마리 역시 용기가 클수록 생체중이 유의하게 높았다. 어린순 품질은 1년생 로즈마리의 경우 용기 2,000mL에서 가장 우수하였으나, 2년생 로즈마리의 경우 시기별 품질 차이를 보였다. 단위 화분당 어린순 생산성은 1,300mL에서 가장 높았으나, 단위 면적당으로 환산할 경우 750mL에서 가장 우수하게 관찰되었다. 따라서 로즈마리 어린순 다단재배를 통한 집약생산에 가장 적합한 용기 크기는 750mL로 판단된다.
