Figure 2

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