Glyphosate-induced structural variations in Commelina erecta L. (Commelinaceae).

The purpose of this study was to analyze the structural variations of Commelina erecta, a glyphosate-tolerant weed, produced by this herbicide. Regrowth shoots (vegetative cloning axes) and seedlings and two glyphosate concentrations: 900 and 1800 grams of acid equivalent per hectare (ga.e.
