Early growth, development and allometry of glyphosate-resistant and susceptible Amaranthus palmeri in response to current and elevated temperature and CO₂.

ABSTRACT: This study aimed to evaluate the influence of CO₂ and temperature on glyphosate-resistant and susceptible biotypes of Amaranthus palmeri (Palmer amaranth) in terms of morphological development. Height (cm), stem diameter (cm), leaf area (cm²), number of leaves, leaf, stem, and root dry matter, plant volume (m³), as well as shoot-to-root allometry were evaluated. The Palmer amaranth biotypes were grown under four different scenarios: 1-low temperature (23/33 °C) and CO₂ (410 ± 25 ppm); 2-low temperature (23/33 °C) and high CO₂ (750 ± 25 ppm); 3-high temperature (26/36 °C) and low CO₂ (410 ± 25 ppm); and 4-high temperature (26/36 °C) and CO₂ (750 ± 25 ppm). Between CO₂ and temperature, the majority of dif
