Abstract : A study was conducted in Sirsi, Karnataka, India to determine the influence of allelopathic effects of multipurpose trees, viz., Acacia auriculiformis, Casuarina equisetifolia, Eucalyptus hybrid and Mangifera indica, on the germination behaviour, and root and shoot growth on some important aromatic and medicinal plants, e.g., kasthuri bendi (Abelmoschus moschatus), sanka pushpa (Clitoria ternatea) and honey plant (Ammi majus). A total of 25 seeds of each species were sown in trays filled with sand, and each tray was added with 200 ml of lead leachates (for the treatments) and 200 ml of water (for the control). Generally, the adverse effect of the 4 multipurpose trees differed with each medicinal plant. However, maximum adverse effect for the parameters considered was recorded in the M. indica while minimum adverse effects were observed in Eucalyptus hybrid. Sanka pushpa showed the greatest sensitivity compared to the two other species tested.
