Description

Results of a field study conducted in the summer of 2000 showed that when the antioxidant ethylene diurea (EDU) was applied to crops, there were increases in several parameters. The next step was to verify whether the effects of EDU resulted from EDU-mediated protection against ozone or from plant growth promoting effects of EDU that are independent of ozone. A series of controlled environment trials were designed to test this hypothesis.

Description

Ozone is an important phytotoxic gaseous pollutant and is known or suspected to cause injury in crops, including yield reductions. Studies have been conducted using the antioxidant EDU (ethylene diurea) in programs aimed at the quantification of the effects of ozone on vegetation. For the present study, a protocol making use of EDU as an antioxidant was designed and implemented at a site near the city limits of Fort Saskatchewan, Alberta, an area having elevated ozone levels relative to other areas of the province.
