| Research Abstract |
Radical species released from soybean roots were trapped by spin trapping reagents such as DEPMPO and DBPMPO. The trapped radicals were carbon-centered radicals from their hyperfine coupling constants (aH = 2.15, aN = 1.48, aP =4.60 mT). Based on the decline rate of the signal intensity, three radical species with different half-lives were observed. The radical species were separated by HPLC and identified.
