摘要:
2009年10月25~30日中国珠海发生面积超过300 km2的大规模旋沟藻赤潮.于2009年10月29日作者采集赤潮区水样,对水样中浮游植物进行分析鉴定,研究旋沟藻赤潮水样对中肋骨条藻、海洋原甲藻和赤潮异弯藻生长的影响,揭示旋沟藻赤潮对海洋浮游植物群落结构的影响.研究发现,赤潮水体中,旋沟藻细胞密度为3.15×106 L-1,占浮游植物总密度的73.26%,是绝对优势藻种.旋沟藻赤潮水样对海洋原甲藻和赤潮异弯藻生长抑制作用明显;但对骨条藻生长不但没有明显抑制,且具有一定促进作用.赤潮水样中的抑藻物质主要存在于细胞滤液中,是一种具有水溶性和热稳定性的胞外物质.
Abstract:
A large scale bloom of Cochlodinium,covering over 300 km2,occurred in coastal waters of Pearl River Estuary in China in October 2009.Water samples in the bloom patches were collected during the bloom.Phytoplankton was analyzed,and the effects of bloom sample on the growth of the other three phytoplankton species Skeletonema costatum, Prorocentrum micans and Heterosigma akasiwo were studied.Cochlodinium was the predominant species in the phytoplankton community in the bloom samples,with the cell density of 3.15×106 cells/L and percentage proportion of 73.3%.The growth of P.micans and H.akasiwo was significantly inhibited by the bloom water.However,the bloom water did not inhibit the growth of S.costatum, even accelerated the growth to some extend.The inhibition substances were mainly in cell-free filtrate,and tended to be hot-resistive.
