| Sumario: | The present study aimed to evaluate the effect of chemical and biological scarification on the emergence and growth of Clitoria ternatea L. seeds. The following pregerminative treatments were used: soak in water for 12 h, soak in humic acid for 12 h, soak in humic acid for 24 h, soak in water at 80 ° C for 5 minutes and soak in 90% sulfuric acid for 45 minutes. The following variables were evaluated: percentage of emergence at 3, 6, 9 and 15 days after sowing, plant height (cm), from 30 to 75 days after sowing, on this last day Destructive sampling was used and root length (cm), root weight and forage biomass (g/plant) were evaluated. A tissue analysis was performed on the leaves at 30 and 75 days after sowing to determine the concentration of macroelements. The data were subjected to an analysis of variance and comparison of means by Tukey's test at the 0.05 level of significance. The results showed that when the seeds of C. ternateaare soaked with humic acids for 24 h, the emergence of the seeds improves, also in growth stages the height of the plants, root length, root weight and part increase significantly. In addition, the concentration of macronutrients in leaf tissues. |
