Data are pooled over runs of the experiment. Abbreviations: GR, glyphosate resistant; GS, glyphosate susceptible. Means within a parameter and analysis followed by the same letter are not significantly different according to Fisher’s Protected LSD test at P ≤ 0.05 for fresh weight reduction and P ≤ 0.10 for dry weight reduction. Consists of six Palmer amaranth biotypes. Consists of a group of three glyphosate-resistant (GR) and a group of three glyphosate-susceptible (GS) Palmer amaranth biotypes. |
