Fig. 8: Relationship between differences in transpiration and differences in physiology.

Relationship between differences in transpiration rates and physiological differences of maximum LAI (a), root hydraulic conductance (Krs; b) and phenology (c) between a modern cultivar and historical cultivar. Colors of hexagons indicate the data density in the respective hexagon over ~5.4 million location-year combinations (European Union; 1990–2020). Black lines and annotations show results of a linear regression.
