title: Effect of simazine on nitrate reductase activity in corn.
abstract: The nutritional and environmental parameters required for eliciting increases in the nitrogen content and growth of corn (Zea mays L.) by non-toxic levels of simazine have been established. Corn seedlings with the endosperm removed 10 days after germination, proved to be a suitable test species. The addition of simazine to the root-zone area of corn plants grown under both sub-optimal temperatures and low nitrate levels, increased the nitrogen content and dry weight of the plants by 20 to 25%. This increase was found to be associated with an effect on nitrate reductase.
