Table 1 Interactive effects of exogenous melatonin and selenium on plant morphological characteristics. Effects of different treatments of exogenous MT (0 μM, 50 μM and 100 μM) and Se (Se) (0 μM, 50 μM, 100 μM and 200 μM) on the leaf fresh/dry weight (g), root fresh/dry weight (g), plant height (cm) and leaf area (cm2 plant− 1) of Brassica napus cv. ZS 758
