Abstract

An experiment was conducted to measure rooting and growth of cuttings of rose as affected by cutting length, number of leaflets and cutting position. Test plants were two cultivars of Rosa hybrida 'Red Sandra'(standard) and 'Little Marble'(miniature). Cutting length was 4, 7 or 10cm for 'Red Sandra' and 3, 5 or 7 cm for 'Little Marble'. The number of leaflets left on the five-leaflet leaf was 0, 2, 4 or 5. The cutting position on the stem was between $1{\sim}2,\;3{\sim}4,\;5{\sim}6\;or\;7{\sim}8$ nodes from the shoot tip, which have five leaflet leaves. The most efficient cutting length was 7cm in both cultivars. Treatment with all leaflets left and cutting position at $1{\sim}2$ nodes resulted in good rooting ratio for both cultivars.

본 실험은 장미 삽수의 조제방법이 발근과 발근 후 생육에 미치는 영향을 알아보기 위하여 수행하였다. 실험재료로는 Rosa hybrida 'Red Sandra'와 'Little Marble' 두 품종을 사용하였다. 삽수 길이를 달리한 실험은 'Red Sandra'는 4, 7, 10cm, 'Little Marble'은 3, 5, 7cm 로 처리하였다. 소엽수를 달리한 실험은 삽수당 소엽 5매엽을 0, 2, 4, 또는 5매 남겼다. 삽수 채취부위를 달리한 실험은 꽃봉오리로부터 소엽 5매엽을 첫 마디로 하여 마디별 $1{\sim}2,\;3{\sim}4,\;5{\sim}6,\;7{\sim}8$마디로 4처리하였다. 발근과 생장에 있어 삽수 길이는 두 품종 모두 7cm가 좋았다. 발근률에 있어 소엽을 5매 모두 남기고 $1{\sim}2$마디를 삽수로 이용시 두 품종 모두 좋은 결과를 나타냈다.
