초록
1994년 1월부터 1994년 12월까지 광양만 대도주변 잘피밭에서 잘피 및 착생해조류의 계절 변동을 연구하였다. 잘피의 잎 길이는 수온이 낮은 겨울철에 100cm 이하의 낮은 수치를 보였으며, 봄철에 접어들면서 잎 길이가 계속 증가하여 여름철인 6월과 7월에는 조사기간 중 최고치인 200cm에 달하였다. 그러나 가을철에는 감소하는 양상이었다. 잘피의 현존량은 가을과 겨울에 낮았으나, 봄부터 현존량이 증가하기 시작하여 여름철에는
Seasonal variations of eelgrass and epiphytic algae in eelgrass beds in Kwangyang Bay were studied from January 1994 to December 1994. A peak of the shoot length and standing crop of eelgrass occurred in summer, but low values were observed in fall and winter. The dominant species of epiphytic algae were Callophyllis rhynchocarpa and Champia sp. In spring and summer, while Polysiphonia japonica and Lomentaria hakodatensis in fall and winter. In contrast to the eelgrass, the standing crop of epiphytic algae showed a minimum in summer. There was a gradual increase in the standing crop of epiphytic algae during fall, and a peak of standing crop occurred in winter. Epiphytic algae accounted for approximately
