Morphoanatomic characterization of Gomphrena perennis and Gomphrena pulchella leaves

Background Gomphrena perennis (Gpe) and G. pulchella (Gpu) are perennial glyphosate-tolerant amaranthaceous weeds of central northern Argentina where glyphosate-resistant soybeans grown with no-till. The study leaves morphoanatomy is important to understand environmental adaptation could be used explain herbicide absorption. Leaf surfaces species were previously described for phylogenetic studies, two populations was characterized glyphosate tolerance. There no reports on comparative studies Gpe Gpu. [...]
