The paper reports some data obtained during experimental tests carried out in order to describe the behaviour in the early stages of growth of the two species Typha latifolia and T. angustifolia in relation to the presence of heavy metals in growing medium. In particular, while the germination is not affected by this type of stress, the development of root systems in both species is highly compromised especially in the presence of Cu and Cd. These observations make it possible to suggest the use of these two species as bioindicators to quickly show toxic levels of these pollutants in the environment.

Abstract
The paper reports some data obtained during experimental tests carried out in order to describe the behaviour in the early stages of growth of the two species Typha latifolia and T. angustifolia in relation to the presence of heavy metals in growing medium. In particular, while the germination is not affected by this type of stress, the development of root systems in both species is highly compromised especially in the presence of Cu and Cd. These observations make it possible to suggest the use of these two species as bioindicators to quickly show toxic levels of these pollutants in the environment.File in questo prodotto:
