Abstract

This study was aimed to select the optimal mat condition using existing plant-mats for the efficient planting of bedding Chrysanthemum. At fifty days after cutting with Dendranthema grandiflorum 'Ford', root formation among the treatments using eight different mats outstood with the treatment using 10 mm thick coir net, which has medium inserted between mat layers - called C treatment, compared to other treatments; this treatment had the highest values in the plant height and shoot fresh weight, which were 29 cm and 5.6 g, respectively. On the contrary, in 40 days after transplanting root-formed mats to field, 12 mm thick jute net, which has medium inserted between mat layers, had the highest plants compared to other treatments. However, there was no significant difference in shoot weight compared to C treatment. In experiment of different lengths of cut, the results of growth after transplanting showed that 5 cm long cut performed best compared to 3 and 8 cm long cuts.

이 연구는 화단용 국화의 식재 효율성을 높이기 위한 목적으로 기존에 개발된 식생매트에 삽수를 이용하여 최적의 매트조건을 구명하고자 수행하였다. 8가지 처리 조건의 매트에 Dendranthema grandiflorum 'Ford'를 삽목하고 난 후 50일 후 생육을 조사한 결과, 매트 내 뿌리 분포는 10mm 두께의 중간에 배양토를 삽입한 coir net(C 처리)에서 가장 좋았고, 초장과 지상부 생체중도 각각 29cm, 5.6g으로 동일 조건에서 가장 높은 값을 나타냈다. 뿌리가 형성된 매트를 포장에 정식 40일 후 초장은 12mm 두께의 중간에 배양토를 삽입한 Jute net가 가장 좋았으나, 지상부 생체중은 C 처리와 차이가 없었다. 매트 내 뿌리 형성과 정식 후 삽수 길이별 생육은 길이 5cm인 삽수가 3과 8cm인 것 보다 좋은 결과를 나타냈다.
