水稻黑暗条件下超声强化耐受硝基苯能力研究

目的]模拟自然黑暗条件下常规水稻对不同浓度硝基苯的耐受能力,寻找解决松花江源水中硝基苯污染对农田中水稻灌溉的影响。方法]进行常规水育种发芽,土培后观察水稻生长状态;选用不同浓度的硝基苯试剂进行水稻育种发芽耐受性试验,并对硝基苯含量进行高效液相检测;采用物理超声降解技术结合水生生物降解技术,采用正交试验分析最佳生物降解条件。结果]水稻在11.910、1.191 mg/L硝基苯溶液中长势良好,与对照组在根长、茎长上不存在差异,且在超声条件下水稻对硝基苯的最大耐受力为1 191 mg/L。超声强化降解的最佳条件为：1 191.000 mg/L硝基苯溶液,时间20 min,功率100%。结论]水稻对一定浓度硝基苯具有较强的耐受力和生物降解能力。
