The plants synthetize abig quantity of chemically diverse compounds, which discharged into theenvironment influence in a decisive manner in the species dynamics that formthe agroecosystems, phenomenon denominated allelopathy. The study had the aim of the evaluation of allelopathic effects of turnipaqueous extract under beans and corn seeds. The experimental design wascompletely randomized with five treatments concentrations of 0%, 25%, 50%, 75% and 100% of raw extractand four repetitions. Thegross extract was prepared through the mixture of 50 g of turnips aerial partfresh mass in 450 mL of cold distilled water and then blended in a blender. Themixture was kept in rest in absence of light for 24 hours at 25℃ for posteriorfiltration and dilution of concentrations. They were evaluated the percentage of germination andthe germination velocity index in Germitest paper rolls dampened with theextract or distilled water, according to the treatments and each roll wasdistributed 50 seeds, kept in germination chamber at 25℃ ± 3℃ and 12 hours of photoperiod. At the end ofseven corn and nine beans days, the root length RL and the aerial partAPL were evaluated, and after drying in a hothouse 50℃, the dry mass of root system DMR andaerial part DMAP was determined, by the measure of 20 plantlets of eachtreatment. The results were submitted to an analysis of variance by F test and,when there was statistical significance, it was made the regression analysis test. For therealization of the statistical analysis, the ASSISTAT software was used. Theturnip aqueous extract affected negatively the germination and initialdevelopment of bean and corn plantlets.
