In the present study allelopathic potential of Xanthium strumarium L. was accessed to induce cytological changes in Lentil (Lens esculenta Moench.). For seeds of Lentil were treated with different concentrations (100%, 50% and 25%) of leachates of different plant parts, viz., leaves of young, mature, and senesced stages, flower, stem and seeds of Xanthium strumarium L for 24 hours. Reduction in mitotic index along with increment in abnormality index in a dose dependent manner was recorded in root tip meristem of Lentil over the control. 100% concentration of seed lachates caused maximum reduction of mitotic index with higher abnormality index. Types of abnormalities induced fragmentation of chromosome in prophase, stickiness of chromosome in metaphase and anaphase, C-metaphase, disturbed polarity at anaphase, Chromosome Bridge at both anaphase and telophase and laggard chromosome at telophase. Pronounced inhibitory effects were also recorded in cell size.
