이식된 포기거머리말의 현장 적응성을 알아보기 위해철사고정법으로 포기거머리말을 이식후 이식된 개체(이식구)와 인근 자연군락 포기거머리말 (대조구)의 밀도, 형태적 특성과 생산성의 변화를 약 2년간 조사하였다. 대조구에서는 봄 여름에 증가하고 가을 겨울에 감소하는 밀도변화를 보였으나, 이식구에서는 조사기간 동안지속적으로 증가하였으며, 초기 밀도감소가 나타나지 않았다. 엽초 길이, 잎 폭, 개체 길이와 엽초, 잎, 개체의 무게는 이식초기에는 대조구에 비해 이식구에서 감소하는경향이 보였으나 약 5개월 후부터는 대조구와 이식구가유사해졌다. 잎 생산성도 대조구와 이식구 모두 봄 여름에 증가하고 가을 겨울에 감소하는 뚜렷한 계절 경향을보였으나, 이식초기 이식구의 개체 잎 생산은 생산성이낮은 가을인데도 불구하고 증가하였다. 철사고정법으로이식된 포기거머리말은 개체의 유실이 없었고, 형태적특성으로 보아 약 5개월의 현장적응기간을 소요하는 것으로 판단된다.
Abstract
To evaluate adaptation success of Zostera caespitosa transplants, we transplanted the seagrass shoots at the bare area in close proximity to the donor bed using staple method in October 2005. Shoot density, morphological characteristics and leaf productivity of transplants and reference plants in the vicinity of the planting site were monitored monthly for 2 years. While shoot density of reference plants exhibited significant seasonal variations; increasing during spring and summer and decreasing during fall and winter, that of transplants increased consistently without initial loss during the whole study period. Although sheath length, leaf width and shoot height and weight of sheath, leaf and shoot of transplants were smaller than those of reference plants at the start of transplantation, increased rapidly reaching even higher values than those of reference plants 5 months after transplantation. Leaf productivity of transplants and reference plants showed seasonal variations; increasing during spring and summer and decreasing during fall and winter. But, leaf productivity of transplants increased at the beginning of transplantation during fall which is low production period. All of the Z. caespitosa transplants survived during the whole study period. Rapid changes in shoot morphology and growth of transplants indicated that Z. caespitosa transplants had great morphological plasticity and adapted successfully within 5months.
