Abstract

This study was carried out to examine the effect of cutting condition on rooting and their subsequent growth of cut flower in plug cutting of 'Shinma', one of autumn-flowering chrysanthemums. According to the results, cutting with four or six leaves was effective in shoot growth and rooting than any other treatments, and also the length and thickness of cut flower were increased. In case of cutting with leafless, it showed the poorest shoot growth among all of the treatments and there was no root. The weight of shoot was heavier than any other treatments in case of the length of cutting (5~7 cm). And the weight of root and its number were better than any other treatments, in treatment of the length of cutting (5 cm). The growth of shoot and rooting were enhanced by increasing the thickness of cutting. In case of thickness of cutting, the cutting (3.2 mm tnickenss) showed more favorable shoot length of cut flower than any other treatment. Therefore, it is recommended that the 5 cm long and 3.2 mm thick cuttings with four leaves are used to improve their rooting and subsequent growth in plug cutting of Dendranthema grandiflorum 'Shinma'.

본 연구는 국화 '신마' 품종의 플러그 묘 생산에 있어서 삽수의 조건이 지상부 생육과 발근 및 정식 후의 절화 생육에 미치는 영향을 알아보고자 실시하였다. 삽수에 부착된 잎을 전부 제거한 처리는 지상부 생육이 가장 불량하였고, 전혀 발근이 안 되었다. 잎을 4~6개를 부착하여 삽목하는 것이 지상부 생육 및 발근에 효과적이었다. 삽수길이는 5~7 cm 처리에서 지상부의 무게가 무거웠으며, 발근에 있어서는 다른 처리에 비하여 5 cm 처리에서 뿌리의 무게가 가장 무거웠고, 뿌리수가 가장 많았다. 삽수 굵기가 굵을수록 지상부 생육과 발근이 양호하였다. 삽수에 부착된 엽수가 4~6개인 처리에서 절화장이 길었으며, 줄기의 굵기도 컸다. 삽수의 굵기가 3.2 mm 처리에서 절화장이 가장 길었다. 따라서 국화 '신마' 플러그 묘 생산시 삽수의 굵기가 3.2 mm 정도의 5 cm 길이의 삽수에 4장의 잎을 부착하여 삽목하는 것이 묘의 생육 및 발근에 효과적이고, 정식 후 절화의 생육에도 적합하였다.
