Allelopathic Potential of the Aqueous Extract of Raphanus sativus L on the Germination of Beans and Corn Seeds
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 extract)and 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, ke......
