Flowering and germination are important step of plant life. To study the allelopathic effect of aqueous extracts of Artemisia annua L. on early growth of lettuce, an experiment was designed in a completely accidental plot with 5 treatments (control, 25%, 50%, 75% and 100% of concentration of aqueous extracts) and four times repetition in the laboratory. SAS software was used to analyze the data and Duncan test at 5% of probably level indicated that the effect of different concentrations of extract was significant on morphological characters such as germination rate and percentage, plumule and radicle lengths and fresh and dried weights of seedlings.
