ABSTRACT
The aquatic extracts obtained from the dark dried leaves of Ailanthus excelsa Roxb. (Simaroubaceae) were evaluated in vitro for potential allelopathic effects. The 25%, 50%, 75%, 100% and control concentration was examined for seed germination and seedling growth of Pennisetum glaucum. The A. excelsa aqueous leaf extract shows significant inhibition with increase in concentration. The maximum growth was observed in control pot which shows the average growth of 2.1cm per day and minimum growth was observed in 100% concentration with 0.5cm per day.
