Sažetak
Phenolic acids are natural compounds that can inhibit the growth of many weed species. The objective of this study was to test the inhibitory potential of ferulic acid (FA), vanillic acid (VA), and p-coumaric acid (PCA) on the selectivity of Ambrosia artemisiifolia and maize in vitro. The phenolic acids were applied individually to the seeds in doses (10-7 mol): 200 (FA, VA, PCA), 400 (FA, VA), and 600 (VA). Treatments were applied to 50 seeds of Ambrosia artemisiifolia and 25 maize seeds per Petri dish in three replicates. The inhibitory potential of phenolic acids was estimated from the reduction in germination and early growth parameters 14 and 7 days after treatment of Ambrosia artemisiifolia and maize, respectively. The obtained data were subjected to analysis of variance and differences in mean values were tested in R using Tukey’s test (p < 0.05). PCA showed the greatest overall reduction potential, reducing radicle and hypocotyl length by more than 60%. Higher inhibition was achieved only with 600*10-7 VA by reducing germination by 85%. Maize was not significantly affected by the phenolic acid treatments. The highest reduction of radicle was caused by 200*10-7 mol PCA and 400*10-7 mol FA (16%). Based on the reduction potential against Ambrosia artemisiifolia and the selectivity of maize to PCA and VA, the effect of these phenolic acids will be further investigated in combination applications with reduced doses of herbicides used in maize.
