Institute of Botany, Academy of Sciences of the Czech Republic, Dept. of Mycorrhizal Symbioses, Prùhonice, Czech Republic. The effect of fertilization and arbuscular mycorrhiza (AM) on cadmium (Cd) uptake by tobacco ( Nicotiana tabacum L.) was studied in a greenhouse pot experiment. Two tobacco varieties and five AM fungal isolates were included in this study. Each...
CORESTA Congress, Paris, 2006, AP 36 Effect of arbuscular mycorrhizae on cadmium uptake by tobacco (Nicotiana tabacum) JANOUSKOVA M.; VOSATKA M.; ROSSI L.; MARTIN F.; DONINI P.; LUGON-MOULIN N. Institute of Botany, Academy of Sciences of the Czech Republic, Dept. of Mycorrhizal Symbioses, Prùhonice, Czech Republic. Cadmium (Cd) uptake by tobacco ( Nicotiana tabacum L.) varieties Basma BEK, K326 and TN90 inoculated with five arbuscular mycorrhizae (AM) isolates was studied in a pot experiment. Despite low levels of root colonisation, AM symbiosis affected Cd...
