摘要
20 0 0年 4～ 6月 ,浙江省洞头海区发生了 2次赤潮。经测定 ,在该区栽培的羊栖菜 (Hizikiafusiforme)的鲜干比增加 ,日平均增长率、平均长度减少 ,营养生长减慢。羊栖菜个体的繁殖部分受影响较小 ,假根次之 ,主茎、次生叶 (气囊 )、分枝部分受影响最大 ,后者在羊栖菜产量中的比重最大。但在赤潮发生区的羊栖菜未出现明显病烂现象 ,生长发育正常 。
The red tide occurred in Dongtou sea area(Zhejiang coast) two times from April to June 2000. The growth and product construction of Hizikia fusiforme cultivated there were affected that the average length and daily average growth rate of the spoilt H. fusiforme decreased and so did its nutrient growth. For the individuals, the red tide had a smaller effect on their breeding parts than on their stems, leaves and branch parts. The ratio of wet weight to dry weight of the H. fusiforme grown in red tide waters is higher than that in normal seawater. Despite the red tide, the H. fusiforme grew normally without much rot, which implied that H. fusiforme had certain tolerance to red tide.
