Abstract
Allelopathy is a natural phenomenon that refers to any direct or indirect positive or negative effect of one plant on another through the release of chemical compounds excreted into the environment. In order to evaluate the allelopathic effects of the Bermuda grass (Cynodon dactylon L.) extract on germination and early growth of Basil (Ocimum basilicum L.) and Common purslane (Portulaca oleracea L.), an experiment was conducted in Research station of Islamic Azad University, Isfahan (Khorasgan) branch in 2013. The experiment was arranged as a factorial in a completely randomized design with three replications. The experiment consisted of four stubble concentrations (control, 25, 50 and 100 g/L) along with Basil and Common purslane plants. The results obtained showed that the allelopathic effects of the Bermuda grass extract on coleoptile length, radicale length, coleoptile weight and radicale weight of Basil and Common purslane were significant but for germination percent was nonsignificant. The results of this research revealed that increasing in extract concentration lead to decrease seedling growth of Basil and Common purslane. Our results showed that Bermuda grass extract had strong allelopathic and inhibitory effects on different traits of Basil and Common purslane.
