The effect of cadmium (Cd) was studied on root tips of Pisum sativum L. Seeds of P. sativum were treated with a series of concentrations ranging from 0.125, 0.250, 0.500 and 1.000 mM for 6 h. The effect of Cd was analyzed by studying the percentage seed germination, radicle length (RL), mitotic index (MI) and chromosomal aberrations (CAs) in root tip. The results revealed that Cd had significant impeding effect on the root meristem activity of P. sativum at 0.500 and 1.000 mM as noticed by reduction in seed germination percentage and RL compared to control. Furthermore, it also reduced MI in doserelated manner compared to control. Additionally, the variation in the percentage of mitotic abnormalities was observed. The overall percentage of aberrations generally increased with increasing concentrations of Cd. Among these abnormalities laggards, bridges, stickiness, precocious separation and fragments were most common. The obtained results demonstrated that the Cd treatment leads to a significant reduction in MI and increase in Cas. Overall results allow us to suggest that the Cd has clastogenic effect on the crop.
