Changes in photosynthesis-related parameters in DX and GN under cold stress. a chlorophyll content, (b) the maximum photosystem II quantum yield (Fv/Fm), (c) apparent electron transport rate (ETR), and (d) non-photochemical quenching (NPQ). Each value represents the mean of three replicates ± SE shown by the vertical error bar. The letters above the bars indicate a significant difference at the 0.05 level according to Duncan’s multiple range test
