摘要(Abstract):
【目的】探索波吉卵囊藻(Oocystisborgei)的繁殖模式,调控其生殖过程以实现藻生物质稳定增长。【方法】在荧光显微镜下观察波吉卵囊藻似亲孢子形成过程,探究温度、照度、氮浓度对其繁殖模式的影响。【结果】波吉卵囊藻以2、4和8似亲孢子型模式繁殖,在藻细胞第二轮分裂过程中因分裂不同步,有时也形成3个似亲孢子。氮限制和弱光显著影响波吉卵囊藻繁殖模式(P <0.05)。通常情况下,波吉卵囊藻以4似亲孢子型繁殖模式繁殖,但在缺氮和弱光下2和3似亲孢子型模式的频率上升。在15~35℃温度范围内,波吉卵囊藻繁殖模式变化不大。【结论】波吉卵囊藻有4种繁殖模式。在不良环境中,2和3似亲孢子型模式频率上升。
