Abstract:

将太湖微囊藻水华中3种优势微囊藻包括水华微囊藻1028、惠氏微囊藻929、铜绿微囊藻469和铜绿微囊藻905培养在改良后的BG-11培养基(TN=10mg/L,TP=0.4mg/L)中,然后加入角突网纹溞,以研究3种优势微囊藻对浮游动物摄食压力的形态反应,整个实验共进行了12d.除了水华微囊藻1028以外,在惠氏微囊藻929、铜绿微囊藻469和铜绿微囊藻905中没有观察到有大群体(大于10个细胞)的出现.在水华微囊藻中,处理组大群体细胞所占总细胞的比例与对照组显著不同,其中对照组占22%,而试验组占53%.水华微囊藻对照组和处理组中单细胞、2细胞、小群体(3-10个细胞)和大群体(大于10个细胞)细胞密度存在显著的不同.实验第6-12d,水华微囊藻对照组和试验组单位大群体细胞数量存在显著差异.研究结果表明,角突网纹溞的摄食压力不能促使惠氏微囊藻929、铜绿微囊藻469和铜绿微囊藻905形成大群体.角突网纹溞的摄食促使水华微囊藻形成更大的群体.
