the others exhibited significantly lower accumulations. The highest
correlations were detected between LT50 and DHN accumulation (r =
−0.815), intrinsic water use efficiency
(WUEi; r =
−0.643), net photosynthetic rate (r =
−0.628), stomatal conductance (r = 0.511), and
intracellular/intercellular CO2 concentration (r = 0.505).
