marginally significantP = 0.056
Though marginally significant ( P = 0.056), the DT group had a higher g s under MWD compared to WW conditions (Supplementary Figure S2D ), suggesting a sustained g s may enhance carbon gain (Caldeira et al., 2014 ; Tardieu et al., 2014 ), and subsequently crop yield (Fischer et al., 1998 ; Lu et al., 1998 ), under mild stress conditions.
