Abstract
Eleven day-old grass pea plants (Lathyrus sativus L.) were grown hydroponically for 96 h in the presence of 0.5 mM lead nitrate (Pb(NO(3))(2)). The survival rate was 100%. The mean lead content (measured by ICP-OES) in root tissues was 153 mg Pb g(-1) dry matter. Over three quarters of the lead was not labile. Compared with control plants, lead-exposed plants showed a six-fold, two-fold and three and a half-fold reduction in their root calcium, zinc and copper contents, respectively. Together, these results suggested that Lathyrus sativus L. was tolerant to a deficiency in essential nutrients and able to store large amounts of lead in its root tissues. Therefore, it could be used for the development of new rhizofiltration systems.Entities:
