Differential effects of glyphosate on germination and chlorophyll in Zea Mays plants

Abstract— We studied the glyphosate effect on the germination and chlorophyll content of two corn varieties. The first variety is local "beldi" not improved and the second is a variety selected and imported. Our analysis showed that the imported variety is more tolerant than local. The latter would have been affected by the direct effects of glyphosate by oxidative stress manifesting itself by a strong inhibition of germination and an increased degradation of chlorophyll. However, the imported variety behaved as capable of degrading glyphosate to aminomethylphosphonic acid resulting in improved herbicide resistance
