Fig. 5From: Physiological Responses and Expression Profile of NADPH Oxidase in Rice (Oryza Sativa) Seedlings under Different Levels of SubmergenceThe activities of CAT, APX, SOD and POX in rice seedlings under different levels of submergence. Enzyme activity was detected from detached shoots of 14 days-old rice seedlings after treated control (CK), partial submergence (PS) and full submergence (FS) for 6 days then recovery 1 day (R1D). The catalase (CAT), ascorbate peroxidase (APX), superoxide dismutase (SOD) and total peroxidase (POX) activity were determined, respectively. The data represent average values ± SD from six biologically independent experiments. Values with the different letters are significantly different at P < 0.05, according to post-hoc LSD testBack to article page
