Figure 1

Evaluation of allelopathic activity of ethanolic extracts of Arachis hypogaea (cultivar BR-1) on the growth of hypocotyls and rootlets of L. sativa based on the average lengths of each organ and the inhibition percentages relative to distilled water control. The same letter means no statistically significant difference between the samples in each graphic, according to Tukey’s test.
