Table 3 Correlation coefficients between the plant growth factors, relative root elongation (RRE) and relative shoot extension (RSE), and the plant Cd concentrations in root and shoot versus the tendency index (TI) values of physiological traits, superoxide dismutase (SOD), ascorbate peroxidase (APX), H2O2, and malondialdehyde (MDA)

From: Aspects of cultivar variation in physiological traits related to Cd distribution in rice plants with a short-term stress
