摘要
用不同浓度的阿特拉津(Atrazine)溶液、Hg溶液以及自来水、蒸馏水、湖水对矮牵牛(Petunia hybrida)再生苗(祛花,只留两片叶)进行培养。结果表明:矮牵牛再生苗对低浓度的阿特拉津有一定抗性,高浓度下萎蔫甚至死亡;而汞溶液对矮牵牛再生苗的毒害较大,而且也是随着浓度的增加毒害增大;在湖水、自来水、和蒸馏水中培养的苗生长良好。说明矮牵牛对有机污染物没有抗性,对重金属汞低浓度有些抗性,得出了矮牵牛可以作为指示性植物,也可以应用在水体景观中。
The Petunia hybrida seedling was cultured in different water polluted condition, including atrazine solution, mercury solution, domestic water, distilled water and lake water to understand its adaptability to polluted water condition. Low atrazine solution poisoned Petunia hybrida seedling, when the atrazine concentration increases,Petunia hybri- da seedlings wilt and even die. The similar response was observed in mercury-polluted water. The Petunia hybrida seedling could grow very well in lake water, domestic water and distilled water. The results indicated that the Petunia hybria could be used as indicator plant for heavy metal pollution, and also could be used in Landscape architecture field.
