Abstract
Abstract This study was conducted to examine allelopathic actions of Common Purslane Portulaca oleracea L. aqueous shoot and root extracts on germination of seeds and some growth parameters of wheat ( Triticum aestivum ) and rapeseed ( Brassica napus ). The experiment was performed in sterilized Petri dishes for one week at 22 °C. The experiment was arranged for completely randomized design. The concentrations were chosen for this study as (0%, 3%, 6% and 9%). The results indicated that the higher concentrations (6% and 9%) of both shoot and root extracts of common purslane caused significant reduction in seed germination whereas the lowest concentration caused the least negative impact on seed germination. Other growth polarimeters such as shoot and root length and shoot and root oven dry weight were significantly inhibited by the application of both Common Purslane aqueous shoot and root extracts at concentrations (6% and 9%) in wheat T. aestivum and rapeseed B. napus . However, dicot B. napus turned out to be more effected than monocot T. aestivum. The findings of this study suggest that common purslane aqueous shoot and root extracts can be recommended to utilize as bio-herbicide to supress seed germination and growth of weeds.
