Abstract

Experiments were conducted to measure rooting and growth of rose cuttings as affected by medium composition and volume. Rosa hybrida 'Red Sandra' and 'Little Marble' were used as test plants. For medium composition test, rockwool, phenolic foam, perlite, vermiculite, peatmoss, coir and a commercial medium (Tosilee medium) were applied in single or mixed forms on the propagation bed with fog (200 sec./5 min.) installed to control the humidification time. 'Red Sandra' and 'Little Marble' cuttings were planted in 16-cell plastic pots and 72-cell plug trays, respectively. For the medium volume test, 72-cell plug trays and 16-cell or 9-cell plastic pots were used. Cuttings with an uniform node with a five-leaflet leaf was soaked in a $500mg{\cdot}L^{-1}$ IBA solution for 30 sec. A fogging system installed on the propagation bed was used for (100 sec./5 min.). Rockwool 1 : peatmoss 1 (v/v) was the most effective on growth and rooting for both cultivars and high volume of Tosilee medium and rockwool were most effective media far both cultivars.

본 연구는 배지의 종류 및 부피가 절화 장미의 발근과 발근 후 생육에 미치는 영향을 알아보기 위하여 수행하였다. 실험은 유리온실의 철재 베드에 높이 1.5m의 아치형 터널을 설치하고 습도유지를 위하여 fog(200sec./5min. or 100sec./5min) 가습하고, 삽목초기에 차광률 55%의 한랭사로 차광하였다. 실험재료는 Rosa hybrida 'Red Sandra'와 'Little Marble' 두 품종을 사용하였다. 배지의 종류에 따른 발근 차이를 알아보기 위하여 10가지 배지(토실이 상토, 암면큐브, phenolic foam, perlite, vermiculite, 또는 perlite와 peatmoss 1:1, perlite와 coir 1:1, perlite와 rockwool 1:1, rockwool 1:1, rockwool과 peatmoss 1:1, rockwool과 coir 1:1, v/v)를 준비하여 삽목하였다. 발근배지의 부피에 따른 발근 및 생육의 차이를 알아보기 위하여 3가지의 배지(토실이 상토, 암면큐브, phenolic foam)를 각각 3가지 부피$(3{\times}3{\times}3cm,\;5{\times}5{\times}5cm,\;7{\times}7{\times}7cm)$에 삽목하였다. 배지의 종류를 달리한 실험은 두 품종 모두에서 Rockwool 1: Peatmoss 1 배지에서 발근과 생육에서 가장 좋은 결과가 나타났으며, 배지의 부피에 따른 발근율과 모든 생육은 배지의 용적이 커질수록 좋았다.
