몇 가지 도자기 분 식재 식물의 실내관상 위치에 따른 생장 반응

국문 초록 (Abstract)

몇 가지 도자기 분화 식물의 관상 위치에 따른 생장 반응 을 알아보기 위해 호랑가시나무 (Ilex cornuta Lindl.), 백자단 (Cotoneaster dammeri), 무늬산호수(Ardisia pusilla ‘Variegata’) 및 석곡(Dendrobium moniliforme Sw.)을 수태로 도자기분에 심어 재배온실, 실내의 밝은 쪽, 중간 쪽, 어두운 쪽에서 3개월 간 처리한 후에 식물의 생존율 및 생육 조사를 하였다. 실내위 치에 따른 호랑가시나무의 생존율은 온실이 100%, 실내 밝은 쪽은 80%, 중간은 60%, 어두운 쪽은 60%이었다. 석곡은 호랑 가시나무와 비슷한 생존율을 보였고, 무늬산호수의 생존율은 모든 처리에서 100%이었다. 하지만 백자단은 온실에서 75%, 실내 밝은 쪽은 50%, 중간은 25%, 어두운 쪽은 25%이었다. 호 랑가시나무의 처리기간내의 초장 생장율은 온실이 31.1%, 실 내의 밝은 쪽은 27.3%, 중간 쪽은 27.3%, 어두운 쪽은 4.4%이 었고, 백자단, 무늬산호수 및 석곡의 초장 생장율도 호랑가시 나무와 유사한 경향으로 광도가 낮아질수록 감소하였다. 한편 호랑가시나무의 엽수 증가율 또한 초장 생장율과 비례하여 온 실이 7.5%, 실내 밝은 쪽은 7.2%, 중간 쪽은 6.1% 그리고 어 두운 쪽은 2.7%로 나타났고, 백자단, 무늬산호수 및 석곡의 엽 수 생장율도 호랑가시와 유사한 경향으로 광도가 낮아질수록 감소하였다. 따라서 도자기 분화 식물을 실내에서 오랫동안 관상하기 위해서는 햇볕이 가장 잘 드는 실내 밝은 쪽에서 관 리하는 것이 바람직하다.

To investigate the growth responses of some pottery plants in indoor places, Ilex cornuta Lindl., Cotoneaster dammeri, Ardisia pusilla ‘Variegata’, and Dendrobium moniliforme Sw. were treated in greenhouses, indoor outside, middle side or inside. After 3 months of treatment, the survival rates and growth of plants were investigated. Survival rates of I. cornuta Lindl. were 100% in the greenhouse inside, 80% in indoor outside, 80% in middle side and 60% in inside of indoor. Survival rates of D. moniliforme Sw. showed similar to the I. cornuta Lindl., however the A. pusilla ‘Variegata’ was 100% in all treatments. And survival rates of C. dammeri was 75% in greenhouse inside, 50% in outside, 25% in middle side, and 25% in inside of indoor. The growth rate of plant height after 3 months treatment of I. cornuta Lindl. in greenhouse inside was 31.1%, 27.3% in outside, 27.3% in middle side, and 4.4% in inside of indoor. And the growth rate of C. dammeri, A. pusilla ‘Variegata’, and D. moniliforme Sw. was also similar tendency with I. cornuta Lindl. which was decreased as the light intensity decreased. The increasing rate of plant leaf number also showed proportional with growth rate of plant height. The increasing rate of plant leaf number in the greenhouse inside was 7.5%, 7.2 % in outside, 6.1% in middle side, and 2.7% in inside of indoor. The increasing rate of plant leaf number of C. dammeri, A. pusilla ‘Variegata’, and D. moniliforme Sw. was also similar tendency with I. cornuta Lindl. which were decreased as the light intensity decreased. Therefore, when pottery plants are ornamented in indoor places, it is recommended to keep the plants in brightest part of indoor.
