Abstract

This study was conducted to develop the suitable plant mat for garden mum. The results about growth 2 months after cutting of garden mum (Dendranthema grandiflorum 'White Miri') under 6 different plant-mat treatments using coir tape were as follows. The majorities of cuttings were withered under treatments of non-soiled 15 mm thick mat (C treatment). On the other hand, the same thick mat having a hole filled with soil 3 mm in diameter (D treatment) and the 30 mm thick mat having a hole filled with soil (F treatment) showed the best growth results. The survival rates of treatments D and F showed the higher rates of 100 and 90%, respectively than those of respective 56.3 and 20% of two layers without medium (A treatments) and C treatment having respective 10 and 15 mm thick non-soiled mats. The plant height showing the similar tendency with the result of the survival rate was shown with the lower value of 7.97 and 7.15 cm, respectively under treatments A and C, compared with the higher value of 9.74 and 9.80 cm respectively under treatments D and F. For flower gardening, it is better to adopt treatment D based on the our investigational results that treatment D required less soil than treatment F and had no trouble with forming adventitious roots for manufacturing mats and effective transferring.

화단용 국화에 적합한 식생매트를 개발하기 위하여 coir tape를 이용한 6가지 처리조건의 매트에 Dendranthema grandiflorum 'White Miri'를 삽목한 결과, 매트 두께가 15 mm인 무토양 C처리구에서는 대부분의 삽수가 고사하였으나 동일한 두께의 매트에 직경 3 mm의 구멍을 뚫어 토양을 충전한 D처리구와 10 mm 두께의 매트 사이에 20 mm 두께의 상토가 들어있는 F처리구에서 생육이 가장 양호하였다. 생존율은 각각 식생매트 두께가 10과 15mm인 무토양 처리구인 A와 C처리구에서 가장 저조한 56.3과 20% 결과를 나타낸 반면, D와 F처리구에서 각각 100과 90%의 높은 생존율을 나타냈다. 초장도 처리구별 결과가 생존율의 그것과 비슷하게 A와 C처리구에서 가장 낮은 값인 7.97과 7.15 cm를 나타냈고 D와 F처리구에서 각각 9.74와 9.80 cm의 높은 값을 나타냈다. 이와 같은 결과를 바탕으로 실제로 화단조성에 국화매트를 적용할 경우에 F처리구보다 상대적으로 토양의 양이 적게 들어가고 부정근 유도에 최소한의 토양을 요구하는 D처리구가 매트의 제작 및 이동의 편의성을 위해서는 실용적일 것으로 여겨진다.
