The Hg could inhibit seed germination of Alisma orientale Juzepcz, no seed germination was observed under the Hg solution in this experiment, the reason needs to be studied in the near future. Atrazine along concentration gradient could stimulate seed germination except the low concentration. The seed germination increases with the increasing atrazine content. When the atrazine concentration reaches 50mg/L, the seed germination reaches its peak.
结果表明:重金属汞对泽泻种子有抑制,未能诱发出芽来,其根源还有待于进一步的研究;有机污染物阿特拉津在一定浓度下却促进了泽泻种子的萌发,除了低浓度的T1处理比CK发芽率低以外,随着浓度的增加,发芽率逐渐升高,当阿特拉津浓度为50mg/L时,为泽泻种子发芽率最大值。
