The effect of shoot cutting was tested on cadmium, lead and zinc concentration in leaves and capitula of Erigeron annuus, an invasive species, which is considered as a potential phytoremediator. Plant material and soil were collected in the city center of Kraków, southern Poland, considered as one of the most contaminated cities in Europe. We proved that the concentration of zinc in leaves and capitula was higher after regrowth, concentration of cadmium was lower in capitula than in leaves, and the average value of bio-concentration factor for zinc and cadmium was less than 1, whereas for lead it was greater than 1 in both plant organs. Our results suggested that E. annuus can be potentially used for phytoremediation of lead and cutting the shoots can promote effectiveness of zinc removal from the contaminated soil.
剪枝处理对入侵物种飞蓬（Erigeron annuus）叶片和头状花序中镉、铅和锌浓度的影响，飞蓬被认为是一种有潜力的植物修复剂。植物材料和土壤采集于波兰南部克拉科夫市中心，该城市被认为是欧洲污染最严重的城市之一。我们证明，再生后叶片和头状花序中锌的浓度更高，头状花序中镉的浓度低于叶片，锌和镉的生物浓缩因子平均值均小于 1，而铅在两种植物器官中的平均值均大于 1。我们的研究结果表明，飞蓬可用于铅的植物修复，剪枝处理可以提高从污染土壤中去除锌的效率。
