초록
본 연구는 중부지방에서 동절기간에 적용 가능한 상록지피식물의 이용을 확대하기 위하여 서로 다른 광조건에서의 생장변화를 조사하였다. Nandina domestica는 동절기 동안 광조건에 관계없이 음지에서 높은 엽록소값을 나타냈다. 이후 4월에는 서울의 반포지역에서 엽록소 값이 광조건에 따른 차이는 나타나지 않았으나 북풍에 노출되어 있는 과천지역에서는 양지에서 현저히 감소하였으며 잎이 모두 낙엽 되었다. Ophiopogon japonicus는 지역에 관계없이 2월에 양지보다 음지에서 엽록소값이 두 배 이상의 높은 값을 나타냈으며 L과 b값도 조사기간 동안 음지조건에서 높게 나타났다. 4월에는 반포지역에서 광조건에 따른 차이가 없었으나 과천지역에서는 양지에서 동절기 동안 엽색이 탈색되었다. Pachysandra terminalis는 조사지역과 기간에 관계없이 음지조건에서 엽록소값과 L, b값이 높게 나타났다. 따라서 중부지방에서 상록지피식물을 이용하기 위해서는 음지조건의 조성이 필요할 것으로 여겨진다.
Abstract
Three evergreen ground-cover species were tested and evaluated for cold acclimation with different lights in central Korea to enrich the varieties of ground cover plants for over-wintering. Nandina domestica which recently started to be planted in central Korea had high chlorophyll unit with shade condition in both locations, Banpo and Gwacheon during winter. Light condition had no influence on chlorophyll unit in Banpo after April, meanwhile full sun condition decreased chlorophyll unit significantly in Gwacheon, which is exposed to cold wind from north. Ophiopogon japonicas had more than double chlorophyll unit in shade condition compared to that in full light condition in both investigation areas in February. In addition, higher value of L and b in shade condition had been maintained than in full sun condition throughout investigation period. However, leaves in Gwacheon were de-colorized in full sun condition after over-wintering. Pachysandra terminalis had more higher chlorophyll unit in shade condition compared to in full sun condition in both investigation areas in February. But light conditions had not effect the difference of chlorophyll unit of Gwacheon in April. Therefore, The present results suggest that evergreen ground covers with shade condition would be used as landscape materials in the capital area.
