Values are simulated data on day 77 after the appearance of the first leaf to different architectural traits under 22/18°C (LT) and 32/28°C (HT) day/night temperature. In all cases, standard errors were smaller than 3%. The magnitudes of change in architectural traits are similar to the reported magnitude reported in the literature (Supplementary Table S1).
LN, leaf number, in percentage of leaf number under 0 mM NaCl; cEl,max, parameter for salinity effect on leaf area in Eq. 2 (reference value = -0.0006); IL, internode length, inpercentage of IL under 0 mM NaCl; 𝜃, leaf angle, in percentage of 𝜃 under stress conditions; Wsh,x, shoot dry weight in percentage of the Wsh,x under the correspondent stress conditions; As, total leaf area in percentage of the As under non-stress conditions; Qt/Q0, light transmittance through the canopy in percentage of the light intensity above the canopy.
