Figure 1: Glyphosate dose responses of glyphosate-resistant (GR), glyphosate-susceptible (GS), F1 R × S (GR female × GS male), and F1 S × R (GS female × GR male) Palmer amaranth populations. Points are mean values ± S.E. Best fit curves for these respective populations are: 𝑦 = 1 3 . 4 − 2 . 7 𝑥 , 𝑃 = 0 . 0 3 9 0 , 𝑟 2 = 0 . 9 2 ; 𝑦 = 1 2 . 4 − 4 . 2 𝑥 , 𝑃 = 0 . 0 2 2 1 , 𝑟 2 = 0 . 9 6 ; 𝑦 = 1 4 − 3 . 1 𝑥 , 𝑃 = 0 . 0 2 4 6 , 𝑟 2 = 0 . 9 5 ; and 𝑦 = 1 5 − 3 . 7 𝑥 , 𝑃 = 0 . 0 1 7 0 , 𝑟 2 = 0 . 9 7 .
