Allelopathic Potential of Achillea biebersteinii Afan. (Asteraceae)
نویسنده
چکیده
The effects of different concentrations (0, 25, 50, 75 and 100%) of aqueous leachate of Achillea biebersteinii on germination characteristics, seedling growth, photosynthetic pigments and protein contents of pepper (Capsicum annuum L.) were investigated through conducting laboratory and greenhouse experiments. Leachate of A. biebersteinii affected negatively germination percentage, germination rate and radical and shoot length. When pepper seeds were sown in soil and irrigated with Achilliea leachate, root and shoot length were significantly decreased. However, stem diameter was slightly affected and leaf number was significantly unaffected. Significant reduction in the amount of chlorophyll a, chlorophyll b, total chlorophyll, carotenoids and protein were recorded in response to allelochemical stress
