Abstract利用从我国蜈蚣草主要分布地区收集到的不同蜈蚣草基因型进行田间试验,评价他们耐砷和富集砷的能力.试验结果表明,蜈蚣草基因型在株高、生物量、羽叶数上都表现出显著的不同.株高变化范围为29.6~68.2cm;每株羽叶数变化范围为18.0~60.0个;每株地上部鲜重变化为150~540g;每株根鲜重变化范围为20.3~94.9g.蜈蚣草基因型地上部和根部的砷浓度也表现出显著差异.地上部砷积累浓度变化范围为643.10~3009.03mg·kg^-1,根部砷积累浓度变化范围为26.34~112.38mg·kg^-1.基因型C108地上部积累砷最多,显著大于其它蜈蚣草基因型;研究还发现,蜈蚣草基因型间的转运系数和生物富集系数也存在显著差异.相关分析显示,蜈蚣草富集砷的量与株高、羽叶数、芽苞数等生长特性呈正相关.
