AbstractDrought tolerance and toxicity variation of grass pea (Lathyrus Sativus L.) were studied in the presence and absence of earth element Eu3+ under the pot-culture condition. The addition of exogenous Eu3+, increases the survival days (SD) and lowered the stomatal sensitivity of grass pea seedlings under the decreasing soil moisture from - 0. 2 MPa to - 1 MPa, suggesting that Eu3+ can improve the ability of grass pea seedlings to tolerate drought. But in this case, Eu3+ is found to significantly inhibit the increase in contents of plant toxicity beta-N-oxalyl-L-a, P-diaminopropionic acid (ODAP) level in leaves. Therefore, the results demonstrate that Eu3+ application is a potential agronomic approach to improve drought tolerance while lowering the toxicity level in grass pea productivity.
