Abstract
Chamomile (Matricaria chamomilla L.) is a widely used medicinal plant but may also accumulate metals including cadmium. Because recent paper (Masarovicova et al. 2010 Acta Physiol Plant 32:823–829) contradicts previous results of our research group and suggested Cd “hyper/accumulation” in chamomile, present study examined Cd uptake in a long-term experiment (7 weeks) using low Cd concentration (1.5 μM). Besides, typical Cd hyperaccumulator Thlaspi caerulescens and Ni hyperaccumulator Thlaspi goesingense were also cultured under identical conditions. Data obtained indicate that shoot Cd content and bioaccumulation factor (BAF) in chamomile was ca. 5–10 times lower than that in Thlaspi. In this view, chamomile is not a hyperaccumulator species. Comparison of shoot Cd content, BAF and translocation factor (TF) in selected crops is also provided.
