Abstract:
The effect of different concentrations of allelochemicals including Ephedrin, Vanillin, abscisic acid (ABA), Eucalyptus comadulensis and Juglans ragia leaf and Onobrychis sativa seed extracts were tested on percentage germination, germination start and seedlings growth of Astragalus cycluphgllus. All considered compounds delayed germination start with respect to the control but among these allechemicals different concentrations of ABA and 33.3 mM of Vanillin delayed germination for a longer period than other allelopathic compounds. Ephedrin, Vanllin and Eucalyptus camadulensis leaf extract reduced percentage of germination. In addition, in Ephedrine, Juglans regia compounds seedlings had abnormal growth and twisted form. Therefore, only ABA had no negative effect on percentage of germination and seedling growth.
