PY - 2019/12/05 Y2 - 2024/03/28 TI - GLYPHOSATE TOXICITY STUDY IN CABBAGE AND RADISH GERMINATION JF - Revista Brasileira de Engenharia de Biossistemas JA - Braz J Biosyst Eng VL - 13 IS - 4 SE - Regular Section DO - 10.18011/bioeng2019v13n4p282-289 UR - https://seer.tupa.unesp.br/index.php/BIOENG/article/view/815 SP - 282-289 AB - <p><span style="font-weight: 400;">This work aimed to evaluate the toxic effects of glyphosate (N- (phosphonomethyl) -glycine), a herbicide widely used in Brazilian agriculture, as a stressor, through a methodology of evaluation of chronic and acute toxicity in cabbage (</span><em><span style="font-weight: 400;">Brassica oleracea</span></em><span style="font-weight: 400;"> L.) and radish (</span><em><span style="font-weight: 400;">Raphanus sativus</span></em><span style="font-weight: 400;"> L.) seeds. The chosen methodology allowed the analysis of the parameters NOEC (Not Observable Effect Concentration), LOEC (Lowest Observable Effect Concentration) and EC</span><span style="font-weight: 400;">50</span><span style="font-weight: 400;"> (Effective Concentration) for each species. For radish, it was observed that NOEC appeared in 1 mg L</span><span style="font-weight: 400;">-1</span><span style="font-weight: 400;"> stressor, LOEC at 2 mg L</span><span style="font-weight: 400;">-1</span><span style="font-weight: 400;"> and EC</span><span style="font-weight: 400;">50</span><span style="font-weight: 400;"> at approximately 7 mg L</span><span style="font-weight: 400;">-1</span><span style="font-weight: 400;">. For cabbage, NOEC appeared at 16 mg L</span><span style="font-weight: 400;">-1</span><span style="font-weight: 400;">, LOEC at 18 mg L</span><span style="font-weight: 400;">-1</span><span style="font-weight: 400;"> and EC</span><span style="font-weight: 400;">50</span><span style="font-weight: 400;"> between 14 e 15 mgL</span><span style="font-weight: 400;">-1</span><span style="font-weight: 400;">. It was possible to get, through the study, a high pH control (7.0 for radish and 7.5 for cabbage), high sensitivity and low cost compared to other toxicity tests.</span></p> ER -
