Bridging a Gap between Cr(VI)-Induced Oxidative Stress and Genotoxicity in Lettuce Organs after a Long-Term Exposure

Table 2

Flow cytometry data for roots of L. sativa L. plants exposed to Cr(VI). Values are presented as the mean ± coefficient of variation. Different letters indicate for the same parameter significantly different means ().
