Interactive effects of exogenous melatonin and selenium on photosynthesis traits. Effects of different treatments of exogenous melatonin (MT) (0 μM, 50 μM and 100 μM) and selenium (Se) (0 μM, 50 μM, 100 μM and 200 μM) on the a) Chl a (mg/g FW), bChl b (mg/g FW), c) carotenoids (mg/g FW), d) net photosynthetic rate (μM CO2 m− 2 s− 1) and (e and f) photochemical efficiency of PSII (Fv/Fm) of fully stretched leaves of Brassica napus cv. ZS 758
