초록

상록 Sedum의 이용을 확대하고자 두께와 토양을 각각 달리 처리한 식생매트인 coir tape와 jute net를 이용하여 6품종(S. reflexum 'Blue Spruce', S. rupestre 'Angelina', S. sexangulare, S. sexangulare var. elatum, S. spurium 'Atropurpureus', S. takesimense)을 삽목하여 45일 후 생육을 조사하여 다음과 같은 결과를 얻었다. 모든 단용처리 조건 및 처리요인 간 상호작용에서 분지수 및 초장, 지상부 생체중은 유의한 차이(p<0.001)를 나타냈다. S. takesimense을 제외하고는 모든 처리조건에서 분지가 되지 않은 분지수는 품종 및 매트종류에 상관없이 모래보다 원예용 상토에서 2배 이상 높게 나타났다. 'Angelina'를 제외하고는 품종별 초장은 상토를 처리한 5 mm coir tape에 가장 높았다. 생체중은 상토를 5 mm coir tape에 식재한 'Blue Spruce'가 13.19 g으로 가장 높았다. 매트별 실험에서는 전체적으로 품종에 관계없이 jute net보다 5 mm 두께의 coir tape에서 Sedum의 생육이 좋았다.

This study was conducted to investigate growth responses at 45 days after cutting in six Sedum cultivars (S. reflexum 'Blue Spruce', S. rupestre 'Angelina', S. sexangulare, S. sexangulare var. elatum, S. spurium 'Atropurpureus', S. takesimense) using vegetation mats (individual coir tape and jute treated with different thicknesses and soil compositions) to broaden usefulness of evergreen Sedum cultivars. All the treatments including both single and interaction between treatments showed significant effects (p<0.001) on the number of branches, plant height, and shoot fresh weight except the number of branches treated with different mat types. No. of branches was showed two times in compost than in sand regardless of cultivars and mat types with the exception of S. takesimense showing no added branches in all treatments. Each plant height of all the cultivars except 'Angelina' showed the highest value under the conditions treated with 5 mm thick coir tape using compost. The fresh weight of 'Blue Spruce' treated with 5 mm thick coir tape using compost was 13.19 g of which value was the highest in all treatments. The better growth response in all Sedum cultivars was shown in the treatment of 5 mm thick coir tape than with jute net treatment.
