铁对拟柱孢藻(Cylindrospermopsis raciborskii)和角星鼓藻(Staurastrum spp.)季节动态和生长的影响——以广东大沙河水库为例
拟柱孢藻 角星鼓藻 铁 季节动态 比生长速率 大沙河水库

拟柱孢藻(Cylindrospermopsis raciborskii)和角星鼓藻(Staurastrum spp.)是热带亚热带浮游植物群落中的常见优势种类,为了解铁对2种浮游植物季节动态和生长的影响,本文通过对典型热带水库的野外调查,分析铁与2种藻生物量和相对生物量的季节动态的关系,并通过室内实验分别以无机磷(KH2PO4)和有机磷(C6H13O9P)为磷源,比较3种铁浓度(0.029、0.2...
拟柱孢藻(Cylindrospermopsis raciborskii)是一种入侵蓝藻,能够产生拟柱孢藻毒素(cylindrospermopsin,CYN),严重危害人类健康.现有研究表明该藻已在我国广泛分布,更是华南地区常见的水华蓝藻,但目前对其产毒和起源还缺乏了解.本研究以中国广东省千灯湖分离出的10株拟柱孢藻为材料,对它们的生长、形态和产毒特性进行了观测,并构建了基于nifH和rpoC1基因...
