| 摘 要： | 通过共培养的方法,研究了不同起始密度对赤潮异弯藻和中肋骨条藻、塔玛亚历山大藻和赤潮异弯藻、塔玛亚历山大藻和中肋骨条藻之间种间竞争的影响。结果表明1赤潮异弯藻对中肋骨条藻的生长有一定的抑制作用,随着初始接种时赤潮异弯藻细胞密度的提高,这种抑制作用愈加明显。2塔玛亚历山大藻和中肋骨条藻与塔玛亚历山大藻和赤潮异弯藻之间的种间竞争结果相类似,即起始密度比例为A∶S(H)=1∶4时,中肋骨条藻和赤潮异弯藻分别在竞争中占优势;当起始密度比例为A∶S(H)=1∶1和A∶S(H)=4∶1,塔玛亚历山大藻在竞争中占优势。

| Abstract: | Red tides is a ubiquitous and natural phenomenon caused by the excessive growth of phytoplankton. It has caused serious social problems and heavy damage to fisheries worldwide. Therefore, this has become a major environmental issue in the world. The red tide occurrence can be affected by the effects of the initial cell density on the interspecific competition between different species of red tide microalgae. However, few studies have been focused on the interspecific competition between different microalgae... |
