Protoporphyrinogen oxidase 저해형 Oxyfluorfen 에 대한 식물종간 내성차이 = Originals : Differential Tolerance of Plant Species to Protoporphyrinogen Oxidase - Inhibiting Oxyfluorfen

다국어 초록 (Multilingual Abstract)

The four tolerant and one susceptible plant to oxyfluorfen were selected from 26 species and investigated for the inhibition of protox activity, the PPIX accumulation, and the activity of antioxidative enzymes by oxyfluorfen treatment. When treated, the oxyfluorfen-tolerant plant species showed a less decrease in fresh weight and height than the susceptible one. The susceptible barnyardgrass showed more inhibition of protox activity due to the treatment of oxyfluorfen than the tolerant species. Especially at the concentration of 10^(-6)M, protox activity of the susceptible barnyardgrass was inhibited completely, but tolerant species maintained 25∼45% of the activity. Under the light and dark condition, the susceptible barnyardgrass showed more PPIX accumulation than the tolerant.
