The allelopathic potential of Sesamum indicum L. has been studied in relation to Triticum aestivum L. The seeds of wheat were soaked in aqueous extracts of plant parts of S. indicum at 3, 5, and 8% for 24 h. A pot experiment was conducted to determine the effects of sesame on percent germination, root and shoot length, fresh and dry weight, activities of antioxidant enzymes, phytohormones, and nutrient uptake by wheat roots and shoots. A significant decrease was recorded in the percent germination of wheat seeds treated with sesame plant extracts (maximum by leaf extracts) and shoot length (maximum by 8% stem extracts) concomitant with the marked increase in the root length and weight (maximum increase with 8% leaf extract). The activity of superoxide dismutase, peroxidase and ascorbate peroxidase was increased in wheat roots and shoots treated with different concentrations of S. indicum plant parts. The extracts of all parts of S. indicum increased the indole acetic acid (IAA) content in the wheat roots. Abscisic acid (ABA) content was higher in wheat shoots. The maximum increase in micronutrient uptake was observed at 8% leaf extract. It is inferred from the present study that all parts of S. indicum have allelopathic potential with leaves being more potent. S. indicum extract changes root to shoot ratio and modulate IAA and ABA ratio in root and shoot which can be implicated not only in the control of weed germination but also in combating drought stress in recipient plant.
