Correlation analysis. Correlation of primary panicle digital traits, primary panicle gas exchange (GE) parameters and flag leaf GE parameters at 10 DAF under HS in a TEJ-1 and b TEJ-2. Histograms and red lines represent each trait’s distribution. Green-colored text indicates a similar type of correlation in TEJ-1 and TEJ-2 for the respective traits. Blue-colored text represents contrasting correlation values in TEJ-1 and TEJ-2 for underlying traits. The font size of the text for correlation value is proportional to the actual value of the correlation between the parameters being compared. PPA projected panicle area, VC voxel count, G proportion of green pixel intensity, Apanicle Net CO2 assimilation of primary panicle, Epanicle: Transpiration of primary panicle, Aleaf: Net CO2 assimilation of flag leaf, Eleaf: Transpiration of flag leaf, GE gas exchange.
