Peas (Pisum sativum L. Var Alaska) were allowed to absorb calcium and magnesium chloride for 8 hours and then were germinated in a potassium phosphate buffer pH 6.5 for 40 hours. Peas were then treated with 0, 0.1, 0.3, or 0.5 ppm dicamba (3,6-dichloro-o-anisic acid) and harvested at 24, 48, and 72 hour intervals. The following determinations were recorded: root elongation, nuclear volume, and anatomical modifications.
Root elongation recordings showed that dicamba prevented normal root elongation. Treatments induced very short thick primary roots.
Measurements of nuclear volume indicated that all herbicide concentrations were able to reduce the …
