Abstract:

利用盐生植物抑制藻类生长是防治海洋赤潮发生的一种新兴技术.本文以中国近海典型赤潮原因种中肋骨条藻为对象,研究了滩涂盐生植物盐角草对藻生长的影响及其机制,并利用高效液相色谱技术分析潜在的抑藻物质.共培养实验结果显示,在营养盐充足的条件下,盐角草能够显著抑制中肋骨条藻的生长,降低藻生长水体叶绿素a(Chla)浓度.除盐角草根系水提物之外,其余3种有机相提取物均能抑制藻的生长,改变藻细胞大小,并且影响单个细胞的Chla含量.各种有机相提取物的抑制作用具有浓度效应,随浓度升高抑制作用增强;以甲醇相提取物效果最明显,其次是正丁醇和氯仿相提取物.经高效液相色谱分析,在甲醇相提取物中鉴定出2种黄酮化合物――芦丁和槲皮素-3-β-D-葡萄糖甙.其中芦丁对中肋骨条藻的生长具有一定的抑制作用,其抑制效果随芦丁浓度的升高而增强,随藻细胞初始接种密度的升高而减弱.结果表明,盐角草能够抑制中肋骨条藻的生长,芦丁作为盐角草的代谢产物之一有望成为新的抑藻剂.
