共培养条件下,采用叶绿素含量和叶绿素荧光参数研究穗花狐尾藻分泌的化感物质对铜绿微囊藻光合效率的影响,其中叶绿素荧光参数包括qN(非化学淬灭)、YⅡ(有效量子效率)、Fv/Fm(最大量子产量)、F'v/F'm(光系统Ⅱ有效量子产量)和快速光响应曲线.3 d共培养处理期间,铜绿微囊藻叶绿素含量及叶绿素荧光参数都受到不同程度的影响,不同参数表现出了不同的灵敏性.处理第2 d时,10.0 g/L穗花狐尾藻体系中铜绿微囊藻叶绿素含量抑制率为20.80%,表现出了显著的抑制 ...

巢湖微囊藻(Microcystis)水花(waterblooms)毒性及毒素的研究
本文实验以巢湖微囊藻(Microcystis)水花为材料,采用昆明鼠腹腔注射法对其毒性进行了测试,发现在86年9-11月期间,仅9月8日采自塘西的铜绿微囊藻(M.aeruginosa)水花和9月9日采自忠庙的水花微囊藻(M.flos-aquae)水花是有毒的。铜绿微囊藻(M.aeruginosa)水花的最低致死剂量(LDmin)为90mg干藻/kg鼠重,水花微囊藻(M.aeruginosa)的LDmin大约为1000 mg 干藻/kg鼠重。当注射剂量超过LDmin时,受试动物均在4小时死亡 ...
