摘要
[目的]探讨紫玉兰组织和器官对铜绿微囊藻生长的影响.[方法]在实验室条件下,以南太湖水华蓝藻铜绿微囊藻为材料,研究了不同处理方式的紫玉兰叶和花瓣对其生长的化感抑制作用.[结果]0.10％、0.50％和1.00％的紫玉兰叶提取液、高压灭菌紫玉兰叶和经过次氯酸钠消毒后的新鲜紫玉兰叶对铜绿微囊藻均有不同程度的抑制作用,0.10％紫玉兰花瓣提取液、0.10％高压灭菌紫玉兰花瓣和1.00％新鲜紫玉兰花瓣也可显著抑制铜绿微囊藻的生长.[结论]紫玉兰叶和花瓣中含有抑制铜绿微囊藻生长的化感物质,试验结果为生态控制蓝藻水华提供了理论依据.
Abstract
[Objective] To investigate the effect of the tissue and organs of Yulania liliiflora on the growth of Microcystis aeruginosa.[Method] The allelopathic effect of leaves and petals from Y.liliiflora on M.aeruginosa from south Taihu lake was studied.[Result] The 0.10％,0.50％ and 1.00％ of the Y.liliiflora leaves extract,autoclaved Y.liliiflora leaves and fresh Y.liliiflora leaves disinfected by sodium hypochlorite had obvious inhibitory effect on M.aeruginosa.0.10％ of Y.liliiflora petal extract,0.10％ of autoclaved Y.liliiflora petals and 1.00％ of fresh Y.liliiflora petals also inhibited the growth of M.aeruginosa significantly.[Conclusion] The leaves and petals of Y.liliiflora contain the allelochemicals that can inhibit the growth of M.aeruginosa.The results lay theoretical basis for ecological control on cyanobacterial bloom.
